Summary of the Offering

Issue The Issuer will issue f400,000,000 Floating Rate NationalCapital Instruments (the "NCIs") to investors.

The NCIs will rank pan passu among themselves in all respects.NCIs do not represent deposits or securities of National, areguaranteed by National only to the limited extent as describedunder Summary of Principal Documents—Terms of the NCISubordinated Guarantee below and, apart from under thatlimited guarantee, an NCI Holder has no claim on National forpayment of any amount in respect of the NCIs.

Issue Date

The NCIs are expected to be issued on 29 September 2006 (the"Issue Date").

Maturity Date The NCIs are perpetual instruments with no set maturity date.However, an NCI is redeemable for cash (subject to APRA'sprior written approval) and in certain circumstances will beautomatically converted into a preference share of National("Preference Share") according to the terms of issue of the NCIs(the "NCI Terms").

Use of Proceeds The proceeds of issue of the NCIs will be used to purchase theLLC Notes and the Convertible Debentures as described underSubscription and Sale—Subscription, Assignment and Sale of theRelevant Instruments below.

National New York Branch will use the ultimate proceeds ofissue for its general business purposes including on-lending (seefurther Use of Proceeds below).

Distributions on the NCIs

NCIs will pay distributions ("Distributions") at a floating rate.

Distributions on the NCIs will be paid quarterly in arrears on29 March, 29 June, 29 September and 29 December of each yearcommencing on 29 December 2006 (each a "DistributionPayment Date").

The amount of each Distribution will be calculated inaccordance with the relevant formula set out in the NCI Terms(see Terms and Conditions of the NC's—Distributions below).

9

Distribution Limitations Distributions on the NCIs are limited to interest received by theIssuer from National LLC 1 on the LLC Notes. Payment ofinterest on the LLC Notes is subject to the tests and conditionsset out in the terms of the LLC Notes (see Summary of PrincipalDocuments—Terms of the LLC Notes below). In turn, interest onthe LLC Notes is limited to interest received by National LLC 1from National New York Branch in respect of the SubordinatedDebentures. Payment of interest on the SubordinatedDebentures is also subject to similar tests and conditions as setout in the terms of the Subordinated Debentures (see Summaryof Principal Documents—Terms of the Subordinated Debenturesbelow).

Distributions on the NCIs are non-cumulative and the holders ofthe NCIs (the "NCI Holders") will have no claim for anyDistribution not paid, or for any part of any Distribution notpaid, pursuant to the limitations discussed above.

However, on and from the occurrence of a CapitalDisqualification Event, Distributions on the NCIs will not besubject to the limitations described above but will be absoluteand unconditional liabilities of the Issuer on each DistributionPayment Date.

A "Capital Disqualification Event" will occur if:

(a) the NCIs would not be eligible to qualify (save where suchnon-qualification is only as a result of any applicablelimitation on the amount of such capital) as Tier 1 regulatorycapital for National on a Level 1 or a Level 2 basis underapplicable regulatory capital requirements; and

(b) the Australian Prudential Regulation Authority ("APRA")has confirmed to National in writing that the NCIs wouldnot be eligible to qualify as Tier 1 regulatory capital forNational on a Level 1 or a Level 2 basis.

NCI Subordinated Guarantee National guarantees Distributions on the NCIs, the RedemptionPrice of the NCIs, and, if the Issuer is wound up, the LiquidationAmount of the NCIs, in each case to the extent the Issuer:

(a) has funds available to make the payment after payment ofany creditors it may have; and

(b) does not make the payment,

(the "NCI Subordinated Guarantee") (see Summary of PrincipalDocuments—Terms of the NCI Subordinated Guarantee below).

Consequences of Non-Payment of

Failure to pay in full, for any reason, Distributions on or withinDistributions seven Business Days of the scheduled Distribution Payment

Date, will trigger the Conversion Event (except where a CapitalDisqualification Event has occurred) (see Terms and Conditionsof the NCIs—Conversion), but will not constitute an event ofdefault and will not otherwise entitle the NCI Holder to a returnof its investment.

10

Failure to pay in full, for any reason, Distributions on thescheduled Distribution Payment Date, will also immediatelytrigger distribution restrictions for National as described in theTerms and Conditions of the NCIs—Distributions—Restrictions inthe case of non-payment and, when the Preference Shares areissued, substantially in the form described in Summary ofPrincipal Documents—Terms of the Preference Shares-Dividends—Distribution Restrictions below.

Withholding Tax and Additional

The Issuer will make all payments of Distributions withoutAmounts deduction or withholding for, or on account of, tax unless that

deduction or withholding is required by law. If any deduction isrequired, the Issuer must pay the full amount required to bededucted to the relevant revenue authority and, subject to:

(a) certain exceptions (see Terms and Conditions of the NCIs-Payments to NCI Holders—Gross-up below); and

(b) having received sufficient amounts from National LLC 1 inrespect of the LLC Notes or from National under the NCIGross-Up Indemnity (as defined below),

an additional amount ("Additional Amount") to the NCIHolders so that the NCI Holders receive the same amount inrespect of that payment as if no such deduction had been madefrom the payment.

National will covenant in a deed of covenant entered intobetween National, National LLC 1 and the Issuer (the "Deed ofCovenant") to indemnify the Issuer for the payment of anyAdditional Amounts (see Summary of Principal Documents —Terms of the Deed of Covenant—Undertakings by National below)(the "NCI Gross-Up Indemnity"), subject to the same tests andconditions that apply to payment of interest on the SubordinatedDebentures (see Summary of Principal Documents—Terms of theSubordinated Debentures—Interest below).

Conversion Events In certain circumstances the Conversion Event (as defined in theNCI Terms (see Terms and Conditions of the NCIs—Conversionbelow)) will occur with respect to the NCIs. An NCI Holder maynot initiate the Conversion Event.

Conversion Mechanics Upon the occurrence of the Conversion Event, each NCI will beredeemed in consideration for the delivery of a PreferenceShare in accordance with the steps set out under Summary ofPrincipal Documents—Terms of the Convertible Debentures—Conversion below. In certain circumstances National may beprevented by law from issuing the Preference Shares (seeSummary of Principal Documents—Terms of the ConvertibleDebentures—Failure to Issue Preference Shares below). NCIs willnot convert into Preference Shares after a CapitalDisqualification Event occurs.

Optional Redemption

Subject to APRA!s prior written approval, National has theoption to redeem for cash:

(a) all (but not some) of the Convertible Debentures on theoccurrence of a Regulatory Event, a Tax Event or anAcquisition Event (each as defined in the NCI Terms (seeTerms and Conditions of the NCIs—Interpretation andDefinitions—Definitions below)); and

11

Redemption Price

(b) some or all of the Convertible Debentures on the Step-UpDate or any subsequent date which is a DistributionPayment Date in respect of the NCIs.

A redemption of the Convertible Debentures will, in turn,trigger a redemption of the NCIs for cash (see Terms andConditions of the NCIs Redemption below).

Where the NCIs are redeemed as provided under "OptionalRedemption" above, they will be redeemed in consideration ofthe payment of the Redemption Price. This will generally be anamount equal to the Liquidation Amount of the NCIs plus anyaccrued but unpaid Distribution for the then currentDistribution Period.

See further—Tenons and Conditions of the NC's—Redemption-Redemption Price below.

Voting and Other Rights The agreement under which the Issuer is constituted (the"Issuer LLC Agreement") contains provisions for conveningmeetings of the NCI Holders to consider any matter affectingtheir interests, including any variation of the NCI Terms whichrequires the consent of NCI Holders.

Subject as provided above, NCI Holders will have no votingrights in respect of National Head Office, National New YorkBranch, National LLC 1, the Issuer, the LLC Manager orNational Sub (each a "National Entity") unless and until thePreference Shares are issued (see further Summary of PrincipalDocuments—Terms of the Preference Shares—Voting and OtherRights below).

No Set-Off An NCI Holder has no right to set off any amounts owing by itto any National Entity against any claims owing by any NationalEntity and no offsetting rights or claims on any National Entityif a National Entity does not pay a Distribution or interest whenscheduled under any Component Instrument.

Not Deposit Liabilities The NCIs do not represent deposit liabilities of National or anyaffiliate of National. The NCIs are guaranteed by National onlyto the limited extent provided in the NCI SubordinatedGuarantee and an NCI Holder otherwise has no claim onNational for payment of any amount in respect of the NCIs.

Rating It is expected that the NCIs, when issued, will be assigned arating of "A —" by Standard & Poor's, "A2" by Moody's and"A+" by Fitch.

A credit rating is not a recommendation to buy, sell or holdsecurities and does not comment on the adequacy of marketprice or the suitability of any security for a particular investor. Acredit rating may be subject to revision, suspension, withdrawalor placed on ratings watch at any time by the relevant ratingagency. Each rating should be evaluated independently of anyother rating.

No rating agency has been involved in the preparation of thisProspectus.

Indication of yield The yield depends on a number of factors including:

(a) the amount and timing of any return of investment withrespect to the NCIs; and

(b) the amount of Distributions paid in respect of the NCIs.

12

Under certain assumptions including that the NCIs areredeemed on the Step-Up Date and an issue price of €50,000per NCI, an indication of yield is the Distribution Rate on theNCIs. It is not an indication of future yield and it in no wayindicates that the NCIs will be redeemed on the Step-Up Date.

Listing and admission to trading of

Application has been made to the Commission de surveillance duNCIs secteur financier in its capacity as competent authority under the

Luxembourg act relating to prospectuses for securities (loirelative aux prospectus pour valeurs mobilieres) (the "CompetentAuthority") to approve this Prospectus.

RISK FACTORS

Prospective investors should consider carefully the risks set forth below and the other information contained inthis Prospectus prior to making any investment decision with respect to the NCIs.

Each of the risks highlighted below as being risks relating to National and its business could have a materialadverse effect on National's business, operations, financial condition or prospects, which, in turn, could have amaterial adverse effect on the amount which investors will receive in respect of the NCIs. In addition, each ofthe risks highlighted below as being risks relating to the NCIs could adversely affect the trading price of the NCIsor the rights of investors under the NCIs and, as a result, investors could lose some or all of their investment.

Prospective investors should note that the risks described below are not the only risks faced by the Issuer andNational. The Issuer and National have described only those risks relating to their operations that they considerto be material. There may be additional risks that the Issuer or National currently considers not to be materialor of which it is not currently aware, and any of these risks could have the effects set forth above.

Risks relating to the Issuer

The assets of the Issuer are limited

The assets of the Issuer consist only of its rights against National LLC 1 on the LLC Notes and againstNational on the Convertible Debentures.

If the assets of the Issuer are not sufficient to make payments of Distributions or repayments of theamount invested in respect of the NCIs, then payments to NCI Holders will be reduced.

Under applicable Delaware law, the Issuer cannot make a distribution to an NCI Holder to the extent thatat the time of the Distribution, after giving effect to the Distribution, all liabilities of the Issuer (other thanliabilities to NCI Holders on account of the NCIs) exceed the fair value of its assets.

Risks relating to National and its business

General Economic Activity

The business activities of National are dependent on the level of banking, finance and financial servicesrequired by its customers. In particular, levels of borrowing are heavily dependent on customer confidence,employment trends, the state of the economy and market interest rates at the time. As National conductsits business in various locations, including Australia, the United Kingdom and New Zealand, itsperformance is influenced by the level and cyclical nature of business activity in those locations, which is, inturn, affected by both domestic and international economic and political events. There can be no assurancethat a weakening in the economies in which National operates will not have a material effect on its futureresults.

Risks relating to the business of National

As a result of its business activities, National is exposed to a variety of risks, the most significant of whichare credit risk, market risk, operational risk and liquidity risk. Failure to control these risks could result inmaterial adverse effects on the financial performance and reputation of National.

Credit Risk

Risks arising from changes in credit quality and the recoverability of loans and amounts due fromcounterparties are inherent in a wide range of the businesses of National. Adverse changes in the creditquality of its borrowers and counterparties or a general deterioration in the economic conditions in thelocations in which it operates or globally, or arising from systemic risks in the financial systems, could affectthe recoverability and value of its assets and require an increase in the provision for bad and doubtful debtsand other provisions of National.

Market Risk

The most significant market risks National faces are interest rate, foreign exchange and bond and equityprice risks. Changes in interest rate levels, yield curves and spreads may affect the interest rate marginrealised between lending and borrowing costs. Changes in currency rates affect the value of assets andliabilities denominated in foreign currencies and may affect income from foreign exchange dealing. The

15

performance of financial markets may cause changes in the value of the investment and trading portfoliosof National. National has implemented risk management methods to mitigate and control these and othermarket risks to which it is exposed and exposures are constantly measured and monitored. However, it isdifficult to predict with accuracy changes in economic or market conditions and to anticipate the effectsthat such changes could have on the financial performance and business operations of National.

Operational Risk

Operational risk is the risk of loss resulting from inadequate or failed internal processes, people andsystems or from external events. Losses can result from fraud, errors by employees, failure to documenttransactions properly or to obtain proper internal authorisation, failure to comply with regulatoryrequirements and conduct of business rules, equipment failures, natural disasters or the failure of externalsystems, for example, those of suppliers or counterparties. Although National has implemented riskcontrols and loss mitigation actions and substantial resources are devoted to developing efficientprocedures and to staff training, there are always elements of residual operational risk which cannot beentirely mitigated.

Liquidity Risk

The inability of any bank, including National, to anticipate and provide for unforeseen decreases orchanges in funding sources could have consequences on such bank's ability to meet its obligations whenthey fall due.

Impact of Regulatory Changes

National is subject to financial services laws, regulations, administrative actions and policies in thelocations in which it operates. Changes in supervision and regulation, in particular in Australia, couldmaterially affect the business of National, the products and services offered or the value of its assets.Although National works closely with its regulators and continually monitors the situation, future changesin regulation, fiscal or other policies can be unpredictable and are beyond the control of National.

National is subject to capital requirements that could limit its operations

National is subject to capital adequacy guidelines adopted by the APRA for a bank or a bank holdingcompany, which provide for a minimum ratio of total capital to risk-adjusted assets both on a solo basisand on a consolidated basis. National's failure to maintain its ratios may result in administrative actions orsanctions against it which may impact its ability to fulfil its obligations under the Subordinated Debentures(with the effect that the Issuer would not be able to make scheduled payments on the NCIs) or thePreference Shares (if issued). APRA has recently revised its capital adequacy regime following theintroduction of Australian equivalent International Financial Reporting Standards ("AIFRS"). This revisedregime became effective on 1 July 2006 and the NCIs are being issued under this regime. The revisedregime also provides for transition arrangements and National is working in conjunction with APRA as tothe application of transition provisions to it.

In addition, the risk-adjusted capital guidelines (the "Basel Accord") promulgated by the Basel Committeeon Banking Supervision (the "Basel Committee"), which form the basis for APRAs capital adequacyguidelines, have recently been revised. In June 2004, the Basel Committee published InternationalConvergence of Capital Measurement and Capital Standards, a Revised Framework ("Basel II"). APRAcurrently expects to implement Basel II on a common starting date of 1 January 2008. The principalchanges effected by the revised guidelines include the application of risk-weighting (depending upon thecredit status of certain customers, using an "internal ratings-based" approach to credit risk, and subject toapproval of supervising authorities), allocation of risk assets in relation to operational risk and supervisoryreview of the process of evaluating risk measurement and capital ratios. At this time, National is unable topredict how the revised guidelines will affect its calculations of capital and the impact of these revisions onother aspects of its operations.

16

Risks relating to the NCIs

NCIs may not be a suitable investment for all investors

Each potential investor in any NCIs must determine the suitability of that investment in light of its owncircumstances. In particular, each potential investor should:

(a) have sufficient knowledge and experience to make a meaningful evaluation of the NCIs, the meritsand risks of investing in the NCIs and the information contained or incorporated by reference in thisProspectus;

(b) have access to, and knowledge of, appropriate analytical tools to evaluate, in the context of itsparticular financial situation, an investment in the NCIs and the impact such investment will have onits overall investment portfolio;

(c) have sufficient financial resources and liquidity to bear all of the risks of an investment in the NCIs,including where the currency for payments in respect of the NCIs is different from the potentialinvestor's currency;

(d) understand thoroughly the terms of the NCIs; and

(e) be able to evaluate (either alone or with the help of a financial adviser) possible scenarios foreconomic, interest rate and other factors that may affect its investment and its ability to bear theapplicable risks.

The NCIs are complex fmancial instruments. A potential investor should not invest in NCIs unless it hasthe expertise (either alone or with a financial adviser) to evaluate how the NCIs will perform underchanging conditions, the resulting effects on the value of the NCIs and the impact this investment will haveon the potential investor's overall investment portfolio.

If National's financial condition were to deteriorate, holders could lose all or a part of their investment

If National's financial condition were to deteriorate, payments of distributions or other payments on theSubordinated Debentures (and, therefore, the NCIs) or the Preference Shares (if issued) could besuspended and holders would not receive any distributions or other payments. Potential investors shouldnot assume that unfavourable market or other conditions or events will not harm National's financialcondition. If National liquidates, dissolves or winds up, NCI Holders and holders of the Preference Shares(if issued) could lose all or a part of their investment. No Component Instrument is a deposit liability ofNational for the purposes of the Banking Act or any other similar law of any jurisdiction and noComponent Instrument will be insured by any governmental agency or compensation scheme of Australiaor any other jurisdiction.

If National does not issue the Preference Shares pursuant to the terms of the Convertible Debenturesfollowing the occurrence of the Conversion Event, NCI Holders will not receive them and will continue tohold the NCIs, and the LLC Notes will automatically vest in National Head Office as assignee (see furtherSummary of Principal Documents—Terms of the LLC Notes—Assignment below). In addition, in the event ofthe liquidation or dissolution of the Issuer in circumstances where National has not issued the PreferenceShares in redemption of the NCIs, NCI Holders may not receive the full Liquidation Amount per NCI andthe accrued and unpaid distribution for the then current Distribution Period if the Issuer does not havesufficient funds after it pays any creditors it may have.

Distributions on the NCIs are subject to payment and other restrictions and are non-cumulative

A Distribution on the NCIs will only be payable if and to the extent that the Issuer has sufficient funds tomake the payment of that Distribution. The funds available to the Issuer in respect of any DistributionPayment Date will be limited to the interest received from National LLC 1 on the LLC Notes. Payments ofinterest on the LLC Notes are limited to payments received by National LLC 1 on the SubordinatedDebentures. In addition, interest on the LLC Notes and the Subordinated Debentures is subject to thepayment tests and conditions described in the LLC Notes and Subordinated Debentures (see Summary ofPrincipal Documents—Terms of the LLC Notes and Summary of Principal Documents—Terms of theSubordinated Debentures for details of these tests and conditions). These conditions include the exercise ofthe sole discretion of:

(a) in the case of the LLC Notes, the LLC Manager as manager of National LLC 1; and

17

(b) in the case of the Subordinated Debentures, the directors of National.

Distributions will only be paid when so determined and applicable law so permits, if sufficient resourcesexist and if all the conditions to payment are satisfied. NCI Holders will not be entitled to recover missedDistributions because they are non-cumulative. Accordingly, if Distributions on the NCIs for anyDistribution Period are not paid, the NCI Holders will not be entitled to receive such Distributions (or anypayment in respect of such Distributions) whether or not funds are, or subsequently become, available.

Upon the occurrence of the Conversion Event (see further Summary of Principal Documents—Terms of theConvertible Debentures—Conversion below), unless National is legally unable or otherwise fails to issue thePreference Shares on the scheduled Conversion Date, the NCIs will be redeemed for Preference Shares.Dividends on the Preference Shares are also non-cumulative and subject to payment tests and conditions(see Summary of Principal Documents—Terms of the Preference Shares below). If the Conversion Event isthe failure of the Issuer to pay a Distribution in full on the NCIs and of National to pay that amount underthe NCI Subordinated Guarantee, holders of the Preference Shares issued as a result of that ConversionEvent will also not receive any Dividends on those Preference Shares for the corresponding Dividendperiod, unless National pays an Optional Dividend in its absolute discretion and with the consent ofAPRA. National will pay Dividends on the Preference Shares only if and when declared by the directors. Ifthe directors do not declare all or any part of a Dividend payable on any Dividend Payment Date, thenholders will have no right to receive that Dividend at any time, even if National pays other Dividends in thefuture.

Distributions on the NCIs may be restricted by the terms of other similar instruments

The terms of certain of National's outstanding instruments could limit National's ability to make paymentson the Subordinated Debentures, the Convertible Debentures or the Preference Shares (if issued). If theIssuer does not make payments on the NCIs, distributions may not be permitted to be made in respect ofother capital instruments National has previously issued having similar economic rights and benefits as theNCIs (such as certain other Tier 1 capital instruments issued by National, directly or indirectly). If ascheduled payment is not made in full on those capital instruments, Distributions will not be permitted tobe made in respect of the NCIs.

Perpetual nature of the NCIs and the Preference Shares

Neither the NCIs nor the Preference Shares (if issued) have a fixed final maturity date and holders have norights to call for the redemption of the NCIs or the Preference Shares. Although the NCIs or thePreference Shares (if issued) may be redeemed (subject to APRAs prior written approval) in certaincircumstances (including at National's option on the Step-Up Date or on any Distribution Payment Datethereafter or following the occurrence of a Tax Event, a Regulatory Event or an Acquisition Event throughthe redemption of the Convertible Debentures which will, in turn, trigger a redemption of the NCIs), thereare limitations on National's ability to do so. Therefore, holders should be aware that they may be requiredto bear the financial risks of an investment in the NCIs for an indefinite period of time.

If a holder wishes to obtain the cash value of its investment, that holder will have to sell the NCIs or thePreference Shares (if issued). Neither the Distribution Rate on the NCIs nor the rate of Dividend on thePreference Shares will be adjusted to reflect subsequent changes in interest rates or other marketconditions, National's results of operations or financial condition or any decline in the market price ofNational's ordinary shares. As a result, a holder may not be able to sell the NCIs or the Preference Shares(if issued) for the amount of that holder's original investment.

NCIs may be redeemed at the option of National

National's ability to cause the NCIs to be redeemed may limit the market value of the NCIs (see Summaryof Principal Documents—Terms of the Convertible Debentures and Terms and Conditions of the NCIs-Redemption for the circumstances in which this optional redemption right may be exercised by National).During any period when National may elect to cause the NCIs to be redeemed, the market value of theNCIs generally will not rise substantially above the price at which they can be redeemed. This also may betrue prior to any redemption period. The Preference Shares (if issued) will be subject to similarredemption rights and, accordingly, their market value may be similarly limited.

In the period post the Step-Up Date, National may be expected to bring about the redemption of the NCIsor the Preference Shares (if issued) when its cost of borrowing is lower than the Distribution Rate on the

18

NCIs or the Preference Shares (as the case may be). At those times, an investor generally would not beable to reinvest the redemption proceeds at an effective rate as high as the rate of Distribution on the NCIsor the rate of Dividend on the Preference Shares (as the case may be) being redeemed and may only beable to do so at a significantly lower rate. Potential investors should consider reinvestment risk in light ofother investments available at that time.

NCIs may be converted into Preference Shares

Because NCI Holders will receive Preference Shares when the Conversion Event occurs (unless National islegally unable or otherwise fails to issue the Preference Shares at that time), in connection with anyinvestment decision with regard to the NCIs, investors are also making an investment decision with regardto the Preference Shares. Prospective investors should carefully review all the information regarding thePreferences Shares contained in this Prospectus.

If NCI Holders receive Preference Shares following the Conversion Event, the trading value of thosePreference Shares may be lower than the trading value of the NCIs, which may result in a lower returnupon a sale of those Preference Shares.

Subordination

National's obligations under the Subordinated Debentures, the Convertible Debentures and the NCISubordinated Guarantee are unsecured and will rank subordinate and junior in right of payment toNational's obligations to its depositors and other creditors, including other subordinated creditors, otherthan subordinated creditors holding subordinated indebtedness that by its terms ranks equally with, orjunior to, the holders of the Subordinated Debentures the Convertible Debentures and the NCISubordinated Guarantee. Accordingly, National's obligations under the Subordinated Debentures, theConvertible Debentures and the NCI Subordinated Guarantee will not be satisfied unless it can satisfy infull all of its other obligations ranking senior to the Subordinated Debentures, the Convertible Debenturesand the NCI Subordinated Guarantee.

Further, in the event that National is wound-up, liquidated or dissolved, the assets of National would beavailable to pay obligations under the Subordinated Debentures or in respect of the Preference Shares (ifissued) only after all payments have been made on such senior liabilities and claims.

There are no terms in the NCIs, the LLC Notes, the Subordinated Debentures, the ConvertibleDebentures, the NCI Subordinated Guarantee or the Preference Shares (if issued) that limit National'sability to incur additional indebtedness, including indebtedness that ranks senior to or equally with theSubordinated Debentures, the Convertible Debentures, the NCI Subordinated Guarantee or thePreference Shares (if issued) or to issue other instruments which rank senior to or equally with theSubordinated Debentures, the Convertible Debentures, the NCI Subordinated Guarantee or thePreference Shares (if issued). For example, as part of its ongoing capital management programme,National issued A$400,000,000 of similar Tier 1 capital instruments in the Australian markets on18 September 2006.

Although the NCIs may pay a higher rate of interest than comparable instruments which are notsubordinated, there is a real risk that an investor in NCIs will lose all or some of his investment shouldNational become insolvent.

The NCIs and the Preference Shares have limited voting rights

A NCI Holder has no voting rights in respect of the Issuer and has limited voting rights at a meeting ofNCI Holders (see Terms and Conditions of the NCIs—General provisions—Voting and Description of theIssuer—Issuer LLC Agreement below). A holder of Preference Shares after the Conversion Date will alsohave limited voting rights as a shareholder of National (see Summary of Principal Documents—Terms of thePreference Shares—Voting and Other Rights below). This limits the rights of holders to take action withrespect to the NCIs or the Preference Shares (as the case may be).

In addition, holders acknowledge in the terms of the NCIs and in the terms of the Preference Shares (ifissued) that they have no right to apply for the winding-up or administration of any of National HeadOffice, National New York Branch, National LLC 1, the Issuer, the LLC Manager or National Sub (each a"National Entity"), or to cause a receiver, or a receiver and manager, to be appointed in respect of aNational Entity merely on the grounds that the National Entity does not make a scheduled payment ofDistributions or interest.

19

NCI Holders will not receive Preference Shares on the Conversion Date if National is legally unable orotherwise fails to issue the Preference Shares

If on the Conversion Date National is prohibited by law from issuing the Preference Shares, National willissue the Preference Shares if and when it is no longer prohibited from doing so.

Under current Australian law, National may be prevented from issuing the Preference Shares on theConversion Date if:

• National is in liquidation;

• APRA has assumed control of National under the Banking Act 1959 of Australia (the "Banking Act")and APRA does not cause National to issue the Preference Shares; or

• APRA has appointed a statutory manager under the Banking Act to take control of National'sbusiness and the statutory manager does not cause National to issue the Preference Shares.

See further Summary of Principal Documents—Terms of the Convertible Debentures—Failure to IssuePreference Shares below.

A holder of NCIs has no rights as a shareholder of National

A holder of NCIs, will not have any rights conferred on holders of the Preference Shares, including rightsto receive any Dividends or other distributions in respect of the Preference Shares or to vote as a holder ofthe Preference Shares, until the Preference Shares are issued on the Conversion Date.

There is no prior market for NCIs or the Preference Shares

The NCIs and the Preference Shares (if issued) each constitute new issues of securities with no establishedtrading market. National cannot predict whether an active or liquid trading market for the NCIs or thePreference Shares (if issued) will develop or be sustained.

Therefore, investors may not be able to sell their NCIs or their Preference Shares (if issued) easily or atprices that will provide them with a yield comparable to similar investments that have a developedsecondary market. Illiquidity may have a severely adverse effect on the market value of the NCIs or thePreference Shares (if issued).

Modification, waivers and substitution

Exchange rate risks and exchange controls

Distributions and repayments of amounts invested in respect of the NCIs and the Preference Shares (ifissued) will be made in Euro. This presents certain risks relating to currency conversions if an investor'sfinancial activities are denominated principally in a currency or currency unit (the "Investor's Currency")other than Euro. These include the risk that exchange rates may significantly change (including changesdue to devaluation of Euro or revaluation of the Investor's Currency) and the risk that authorities withjurisdiction over the Investor's Currency may impose or modify exchange controls. An appreciation in thevalue of the Investor's Currency relative to Euro would decrease (a) the Investor's Currency-equivalentyield on the NCIs or the Preference Shares (if issued), (b) the Investor's Currency-equivalent value of anyrepayments of amounts invested in respect of the NCIs or the Preference Shares (if issued) and (c) theInvestor's Currency-equivalent market value of the NCIs or the Preference Shares (if issued).

Government and monetary authorities may impose (as some have done in the past) exchange controls thatcould adversely affect an applicable exchange rate. As a result, investors may receive lesser amounts inrespect of the NCIs or the Preference Shares (if issued) than expected, or no amounts.

Credit ratings may not reflect all risks

One or more independent credit rating agencies may assign credit ratings to the NCIs. The ratings may notreflect the potential impact of all risks related to structure, market, additional factors discussed above, andother factors that may affect the value of the NCIs. A credit rating is not a recommendation to buy, sell orhold securities and may be revised or withdrawn by the rating agency at any time.

Legal investment considerations may restrict certain investments

The investment activities of certain investors are subject to legal investment laws and regulations, or reviewor regulation by certain authorities. Each potential investor should consult its legal advisers to determinewhether and to what extent (a) NCIs or, if issued, the Preference Shares, are legal investments for it,(b) NCIs or, if issued, the Preference Shares, can be used as collateral for various types of borrowing and(c) other restrictions apply to its purchase or pledge of any NCIs or, if issued, the Preference Shares.Financial institutions should consult their legal advisors or the appropriate regulators to determine theappropriate treatment of NCIs under any applicable risk-based capital or similar rules.

There are several provisions of Australian law that are relevant to the ability of any person to gain controlof National.

Mergers, acquisitions and divestments of Australian public companies listed on the ASX (such as National)are regulated by detailed and comprehensive legislation and the rules and regulations of the ASX.

In summary, under the Corporations Act, a person must not acquire a relevant interest in issued votingshares in an Australian listed company if, broadly, because of the transaction, that person's or someoneelse's voting power in the company increases from 20% or below to more than 20%, or from a startingpoint that is above 20% and below 90%, unless those shares are acquired in a manner specificallypermitted by law. This restriction also limits the options available to a shareholder wanting to sell ashareholding of more than 20% in an Australian listed company.

Australian law also regulates acquisitions which would have the effect, or be likely to have the effect, ofsubstantially lessening competition in a market in Australia, in a state or in a territory of Australia.

Acquisitions of certain interests in Australian listed companies by foreign interests are also subject toreview and approval by the Treasurer of the Commonwealth of Australia ("Australian Treasurer").

There are also specific limitations on the acquisition of a shareholding in a bank under the Financial Sector(Shareholdings) Act 1998 of Australia (the "FSSA"). Under the FSSA, a person (including a company)must not acquire an interest in an Australian financial sector company where the acquisition would takethat person's voting power (which includes the voting power of the person's associates) in the financialsector company to more than 15% of the voting power of the financial sector company without firstobtaining the Australian Treasurer's approval. Even if a person has less that 15% of the voting power, theAustralian Treasurer has the power to declare that a person has practical control of that company and, byapplying for an order from the Federal Court of Australia may require the person to relinquish thatcontrol. The definition of a financial sector company includes banks such as National.

In accordance with Article 35(3) of Regulation (EC) No 809/2004 (the "Prospectus Regulation"), theobligation to restate historical financial information according to Regulation (EC) No 1606/2002 (the "IASRegulation") set out in Annex XI item 11.1 of the Prospectus Regulation does not apply to National. Thefinancial information relating to National in the Full Year Reports described above and incorporated byreference in this Prospectus has therefore been prepared in accordance with Australian GenerallyAccepted Accounting Principles ("AGAAP") and not in accordance with the international accountingstandards adopted pursuant to the procedure of Article 3 of the IAS Regulation. However, the financialinformation relating to National in the 2006 Half Year Report described above and incorporated byreference into this Prospectus has been prepared in accordance with AIFRS.

There may have been material differences in the financial information had the same accounting standardsbeen applied to each of the Financial Reports.

The financial statements referred to above contain both National's own statements and consolidatedstatements for the National Group.

See further Documents Incorporated by Reference above.

Auditing of historical annual financial information

The historical annual financial information referred to above has been audited; please see the Auditors'Statements at page 228 of the Annual Report on Form 20-F for the year ended 30 September 2004 and atpages 251 and 252 of the Annual Report on Form 20-F for the year ended 30 September 2005 which areincorporated by reference in this Prospectus.

Legal and arbitration proceedings

Except as listed below, there are no governmental, legal or arbitration proceedings (including any suchproceedings which are pending or threatened of which National is aware) in the 12-month period beforethe date of this Prospectus which may have, or have had in the recent past, significant effects on thefinancial position or profitability of National and/or that of the National Group.

On 29 August 2003, a civil class action complaint was filed in the US District Court, Southern District ofNew York, against the National Group and others for alleged violations of the US federal securities lawrelating primarily to disclosure concerning the valuation of the mortgage servicing rights held byHomeSide US (sold in October 2002). The complaint failed to specify any quantum of damages. Theplaintiffs in the complaint filed their consolidated amended class action complaint on 30 January 2004, andthe National Group moved to dismiss the consolidated amended class action complaint on 11 March 2004.It is anticipated that the court will rule on the motion to dismiss during the 2006 financial year.

On 26 February 2004, National announced that it had received a voluntary document request from the USSecurities and Exchange Commission ("SEC") as part of an investigation into certain Australianregistrants and public accounting firms. The document request covers National and controlled entities andincludes issues relating to audit independence. In addition, National has provided certain information tothe SEC about the accounting and internal controls of National and its controlled entities, including theforeign currency options trading matter and HomeSide US.

For further information on contingent liabilities of the National Group, refer to note 44 in the financialreport included in National's Annual Report on Form 20-F for the year ended 30 September 2005incorporated by reference into this Prospectus. These contingent liabilities include amended assessmentsfrom the Australian Tax Office regarding ExCaps and amended assessments from the New Zealand InlandRevenue Department.

Recent events

National continues to consider a range of options to optimise its corporate structure to best support thebank's operations domestically and internationally.

A non-operating holding company structure is one of the options being considered in response to thechanging regulatory environment and its impact on capital and for future flexibility to deliver shareholdervalue.

34

Consideration of various structural options involves a range of complex issues and the analysis and anysubsequent decision on a particular path are expected to take some time to complete. National is currentlyparticipating in industry-wide consultation with regulators in relation to the matter.

As part of any structural review process, National remains committed to retaining the existing level ofcredit ratings for the National Group.

Any non-operating holding company would continue to be regulated by APRA.

Once any proposal is sufficiently advanced stakeholders will be consulted.

There are no recent events particular to National that are, to a material extent, relevant to the evaluationof its solvency.

Significant change in the financial or trading position of National

There has been no significant change in the financial or trading position of the National Group since31 March 2006.

If two or more of the Reference Banks provide the relevant quotation, the arithmetic meanshall be calculated as described above on the basis of the quotations supplied. If less thantwo Reference Banks provide a quotation, then EURIBOR for the relevant DistributionPeriod shall be the arithmetic mean (rounded if necessary to the nearest one-ten-thousandthof a percentage point, with 0.00005 being rounded upwards) which leading banks in theEuro-zone, selected by the Calculation Agent are quoting on the Determination Date toleading European banks for a period of 3 months. If banks so selected by the CalculationAgent are not quoting, EURIBOR for the Distribution Period is the rate in effect for the lastpreceding Distribution Period;

Euro-zone means the region comprised of Member States of the European Union that adopt thesingle currency in accordance with the Treaty establishing the European Community, as amended(the Treaty);

Margin (expressed as a percentage per annum) means, for a Distribution Period:

Upon the registration of the Preference Shares in thename of a nominee of Euroclear and Clearstream, Luxembourg and delivery of the Registered GlobalPreference Share to the common depository for Euroclear and Clearstream, Luxembourg, Euroclear andClearstream, Luxembourg will credit each subscriber with a number of Preference Shares equal to thenumber of NCIs in respect of which the subscriber held an interest through the Registered Global NCIprior to the Conversion Date. The provisions above in relation to Accountholders, &change, Payments andTransfers of Interests will thereafter apply and a reference to NCIs (and holders of interests therein) will betaken to be a reference to Preference Shares (and holders of interests therein).

If those applications are not accepted, registered definitive certificates will be issued in respect of thePreference Shares to each Accountholder in respect of an NCI (if on the Conversion Date an ExchangeDate has not occurred), or otherwise to each NCI Holder, on the Conversion Date.

The following is a summary of certain provisions of the principal documents relating to the transactionsdescribed in this Prospectus and is qualified in its entirety by reference to the detailed provisions of theTransaction Documents.

Terms of the NCI Subordinated Guarantee

General

The terms of the NCI Subordinated Guarantee (the "NCI Guarantee Terms") will be set out in a deed pollgiven by National in favour of NCI Holders.

Under the NCI Subordinated Guarantee National irrevocably guarantees on a subordinated basis and tothe extent set out in the NCI Subordinated Guarantee Terms the following amounts (the "GuaranteedAmounts") payable by the Issuer in respect of the NCIs.

The Guaranteed Amounts are:

• any accrued Distributions;

• the Redemption Price; and

• if the Issuer is wound up, the Liquidation Amount,

in each case including any Additional Amount (as described below) and in each case to the extent theamount is unpaid and, except where there is a Capital Disqualification Event (as described in Terms of theNCI Subordinated Guarantee—Capital Disqualification Event below), the Issuer has funds available to paythat amount after payment of any creditors it may have.

Additional Amounts

National will make all payments under the NCI Subordinated Guarantee without deduction or withholdingfor, or on account of, tax unless that deduction or withholding is required by law. If any deduction isrequired, National must pay the full amount required to be deducted to the relevant revenue authority andan additional amount ("Additional Amount") to the NCI Holder so that the NCI Holder receives the sameamount in respect of that payment as if no such deductions had been made from the payment, except thatno Additional Amount is payable in the circumstances under the NCI Terms as described in the Terms andConditions of the NCIs—Payments to NCI Holders—Gross-Up.

Capital Disqualification Event

If a Capital Disqualification Event occurs (as described in the Terms and Conditions of the NCIs—CapitalDisqualification Event), a claim on the NCI Subordinated Guarantee is not subject to the limitation that theIssuer has funds available to pay that amount but, after the occurrence of an Assignment Date, a claim onthe NCI Subordinated Guarantee in respect of an unpaid Distribution will be subject to equivalentrestrictions relating to retained earnings to those applying to payments of interest on the ConvertibleDebentures after that date.

Obligations of National

Under the NCI Subordinated Guarantee, National agrees that it will:

• comply with its obligations described in Terms and Conditions of the NCIs—Distributions—Restrictionsin the case of non-payment;

• on the occurrence of the conversion of the NCIs:

(a) comply with National's obligations to issue the Preference Shares in accordance with theConvertible Debenture Terms as directed by the Issuer;

(c) pay or reimburse the NCI Holders any amounts on account of certain taxes incurred inconnection with the conversion; and

56

• on the occurrence of an Exchange Event, procure that the Issuer issues Registered Definitive NCIs ifrequired to do so by the NCI Terms, the Issuer LLC Agreement or the Registered Global NCI.

Status and liquidation

The NCI Subordinated Guarantee constitutes an unsecured, subordinated obligation of National.

In the event of the dissolution, liquidation, termination or winding up of National, whether voluntary orinvoluntary, any claim in respect of the NCI Subordinated Guarantee will rank senior to the claims of theordinary shares of National and pan passu with the claims of the holders of the Convertible Debentures,the Subordinated Debentures and the Preference Shares (if issued) and junior to the claims of alldepositors and other creditors of National, other than creditors expressed to rank equally with, or juniorto, the NCI Subordinated Guarantee.

Amendment and Modifications

The NCI Subordinated Guarantee provides that the NCI Guarantee Terms may be amended with the priorwritten approval of APRA (if required) but without the consent or approval of the Issuer or NCI Holdersif National is of the opinion that the amendment:

• is of a formal, minor or technical nature;

• is made to cure any ambiguity or correct any manifest error;

• is expedient for the purpose of enabling NCIs to be listed or to remain listed on a stock exchange orlodged in a clearing system or to remain lodged in a clearing system or to be offered for sale or forsubscription under the laws for the time being in force in any place and it is otherwise not consideredby National to be materially prejudicial to the interests of the NCI Holders as a whole;

• is necessary to comply with the provisions of any statute or the requirements of any statutoryauthority; or

• in any other case, will not materially adversely affect the NCI Holders' rights.

In any other case, the NCI Guarantee Terms may be amended or added to by National if the amendmentor addition has been approved by a Special Resolution.

No Set-off or Offsetting Rights

An NCI Holder has no right to set-off any amounts owing by it to any National Entity against any claimsowing to it by any National Entity, including under the NCI Subordinated Guarantee. An NCI Holder alsohas no offsetting rights or claims on any National Entity if a National Entity does not pay a distribution orinterest when scheduled under any Component Instrument.

Governing Law

The NCI Subordinated Guarantee will be governed by, and construed in accordance with, English law.National irrevocably submits to the non-exclusive jurisdiction of the courts of England to settle anydisputes arising out of the NCI Subordinated Guarantee. National irrevocably appoints National AustraliaBank Limited London Branch, at its registered office at 88 Wood Street, London, EC2V 7QQ as its agentfor the service of process in England.

Terms of the LLC Notes

General

National LLC 1 will issue the LLC Notes to the Initial Subscriber, who will then sell the LLC Notes(together with the Convertible Debentures) to the Issuer, as more fully described under Subscription andSale—Subscription, Assignment and Sale of the Relevant Instruments below.

Each LLC Note will be a fully paid subordinated note, in registered form, denominated in Euro, with aface value and principal amount of €50,000 ("Face Value").

The LLC Notes will rank pan passu among themselves in all respects.

The terms of the LLC Notes (the "LLC Note Terms") will be set out in a tripartite deed between National,National LLC 1 and the Issuer (the "LLC Note Deed").

57

Interest

LLC Note Interest

The LLC Notes will pay interest ("LLC Note Interest") at a floating rate.

LLC Note Interest will be paid quarterly in arrears on 29 March, 29 June, 29 September and 29 Decemberof each year commencing on 29 December 2006 (each a "LLC Note Interest Payment Date"). The LLCNote Interest Payment Dates will match the Distribution Payment Dates in respect of the NCIs (so long asthe NCIs are on issue).

The amount of each payment of LLC Note Interest will be calculated in accordance with the relevantformula set out in the LLC Note Terms, which, will equal the calculation of the Distributions on the NCIs(see Terms and Conditions of the NC's Distributions above).

LLC Note Interest limitations, tests and conditions

Payment of LLC Note Interest on the LLC Notes is subject and limited to the interest received by NationalLLC 1 from National New York Branch on the Subordinated Debentures. Payment of interest on theSubordinated Debentures is subject to tests and conditions (see Summary of Principal Documents—Termsof the Subordinated Debentures below).

Further, a payment of LLC Note Interest is subject to the LLC Manager resolving to pay the LLC NoteInterest and the specific condition that no APRA Condition exists. The circumstances in which an "APRACondition" will exist are set out in the NCI Terms (see Terms and Conditions of the NC's—Interpretationand Definitions—Definitions above).

LLC Note Interest will be cumulative and, accordingly, any unpaid LLC Note Interest ("Accumulated LLCNote Interest") will accumulate. However:

(a) interest will not accrue on any unpaid amount of Accumulated LLC Note Interest;

(b) National LLC 1 is not permitted (unless approved by APRA) to pay any Accumulated LLC NoteInterest until the first LLC Note Interest Payment Date thereafter on which no APRA Conditionexists and the other interest payment tests are met; and

(c) the Issuer (as holder of the LLC Notes) will have no claim for any Accumulated LLC Note Interest, orfor any part of any Accumulated LLC Note Interest, because, upon the occurrence of a ConversionDate or Redemption Date, the Assignment will occur and, accordingly, the rights to suchAccumulated LLC Note Interest will vest in National Head Office pursuant to the Assignment (seefurther Summary of Principal Documents—Terms of the LLC Notes—Assignment below).

Failure to pay in full, for any reason, LLC Note Interest on or within seven Business Days of the scheduledLLC Note Interest Payment Date, will result in the Issuer having insufficient funds to pay, in full, thecorresponding Distribution scheduled to be paid on the corresponding Distribution Payment Date and,accordingly, will trigger the Conversion Event (see Terms and Conditions of the NCIs—Conversion above).Failure to pay the corresponding Distribution in respect of the NCIs will also immediately triggerdistribution restrictions for National as described in the Terms and Conditions of the NCIs—Distributions-Restrictions in the case of non-payment above and, when the Preference Shares are issued, substantially inthe form described in Summary of Principal Documents—Terms of the Preference Shares—Dividends-Distribution Restrictions below but it will not constitute an event of default and it will not entitle the holderof the LLC Notes to take any other action, including, for example, to require that the LLC Notes beredeemed.

On and from the Assignment but prior to the LLC Notes being redeemed, National LLC l's obligation topay LLC Note Interest may be satisfied by National New York Branch paying all interest (if any) payableon the Subordinated Debentures to National Head Office (see further Summary of Principal Documents—Terms of the LLC Notes—Assignment below).

Additional Amounts

National LLC 1 will make all payments of LLC Note Interest without deduction or withholding for, or onaccount of, tax unless that deduction or withholding is required by law. If any deduction is required,

58

National LLC 1 must pay the full amount required to be deducted to the relevant revenue authority and,subject to:

(a) a demand being made for that amount by the Issuer (as holder of the LLC Notes); and

(b) having received sufficient amounts from National New York Branch in respect of the SubordinatedDebentures or from National under the LLC 1 Gross-Up Indemnity (as defined below) and the otherinterest payment tests are met,

an additional amount ("Additional Amount") to the Issuer (as holder of the LLC Notes) so that the Issuerreceives the same amount in respect of that payment as if no such deduction had been made from thepayment.

National will covenant in the Deed of Covenant to indemnify National LLC 1 for the payment of anyAdditional Amounts (See Summary of Principal Documents—Terms of the Deed of Covenant—Undertakingsof National below) (the "LLC 1 Gross-up Indemnity"), subject to the same tests and conditions that applyto payment of interest on the Subordinated Debentures.

Capital Disqualification Event

If a Capital Disqualification Event (as described in the Terms and Conditions of the NCIs—CapitalDisqualification Event above) occurs, LLC Note Interest will not be subject to the limitations describedabove under the Summary of Principal Documents—Terms of the LLC Notes—LLC Note Interest limitations,tests and conditions and will be absolute and unconditional liabilities of National LLC 1 on each InterestPayment Date.

Assignment

On the Issue Date, National Head Office (the "Assignee") will pay the Initial Subscriber the AssignmentPayment (as defined in Subscription and Sale below) in consideration for the rights in connection with theAssignment (as defined below). Payment of the Assignment Payment will entitle the Assignee to receive:

(a) on a Conversion Date;

(b) on a Redemption Date; or

(c) on a Trigger Date after a Capital Disqualification Event occurs, as described in Summary of PrincipalDocuments—Terms of the Convertible Debentures—Capital Disqualification Event,

(an "Assignment Date"), LLC Note Interest and an amount in Euros equal to the Face Value on thatnumber of LLC Notes which equals the number of Convertible Debentures being converted or redeemedon the relevant Assignment Date. Specifically:

(a) until an Assignment Date, all rights to principal and interest on the LLC Notes vest in the Issuer (asholder of the LLC Notes prior to the Assignment); but

(b) on and from an Assignment Date:

(i) all rights to principal and interest payable on LLC Notes in number equal to the number ofConvertible Debentures being redeemed or converted on that date will automatically vest in theAssignee (or, where a Capital Disqualification Event has occurred, all the LLC Notes); and

(ii) that number of LLC Notes will be automatically transferred to the Assignee,

(together the "Assignment"), but without affecting the obligation to pay to the Issuer (as holder of theLLC Notes prior to the Assignment) any Excluded Interest Amounts (as defined below).

An "Excluded Interest Amount" is, in respect of an Assignment Date:

(a) if the Assignment Date is also a LLC Note Interest Payment Date, any accrued but unpaid LLC NoteInterest for the interest period ending on the day before that LLC Note Interest Payment Date; or

(b) if the Assignment Date is not also a LLC Note Interest Payment Date and the Assignment Dateoccurs in connection with a redemption of the NCIs, any amount of LLC Note Interest payable onthat date in accordance with the LLC Note Terms in respect of the period since the immediatelypreceding LLC Note Interest Payment Date (or the Issue Date if there has been no preceding LLCNote Interest Payment Date).

59

For the avoidance of doubt "Excluded Interest Amounts" do not include any other amounts of interest(including any Accumulated LLC Note Interest).

Notwithstanding the Assignment, any Excluded Interest Amount will be paid by National LLC 1 to theIssuer (as holder of the LLC Notes prior to the Assignment).

The Assignment will occur even if National fails to, or is unable on account of applicable law, to issue thePreference Shares on the Conversion Date.

Redemption

The LLC Notes must be redeemed if National New York Branch elects to redeem the SubordinatedDebentures.

On and from the Assignment occurring, National LLC l's obligation to pay to National Head Office (asAssignee) the Face Value and accrued interest on redemption of the LLC Notes will be satisfied byNational New York Branch paying the Face Value and all accrued interest (if any) payable on theSubordinated Debenture to National Head Office. On the Issue Date, National LLC 1 will irrevocablydirect National New York Branch to make those payments, without any further act or direction on the partof National LLC 1.

Liquidation

In the event of the dissolution, liquidation, termination or winding up of National LLC 1, whethervoluntary or involuntary, the Assignee is entitled to claim the Face Value and all accumulated and accruedand unpaid LLC Note Interest on the LLC Notes. Any such claim will rank subordinate to all creditors andother indebtedness of National LLC 1 and senior to the LLC 1 Common Securities.

The Issuer (as holder of the LLC Notes) will acknowledge in the LLC Note Terms that a holder has noright to apply for any National Entity to be wound up, or placed in administration, or to cause a receiver,or a receiver and manager, to be appointed in respect of a National Entity merely on the grounds that aNational Entity does not pay a distribution or interest when scheduled under any Component Instrument.

Amendments and Modifications

The LLC Note Terms can be amended with the prior written approval of APRA (if required) but, incertain limited circumstances (see Description of the Issuer—Issuer LLC Agreement—Amendments andModifications above), without the consent of the NCI Holders or the Issuer (as holder of the LLC Notes).Any other amendment to the LLC Note Terms will require a Special Resolution of NCI Holders and theapproval of the Issuer (as holder of the LLC Notes).

No Set-Off or Offsetting Rights

Each Subordinated Debenture ("Subordinated Debenture") will be a fully paid subordinated note, inregistered form, denominated in Euro, with a face value of E50,000 ("Face Value"). The SubordinatedDebentures will rank pad passu among themselves in all respects.

The Subordinated Debentures will be constituted under a deed poll (the "Subordinated Debenture DeedPoll") and the terms of the Subordinated Debentures (the "Subordinated Debenture Terms") will bescheduled to the Subordinated Debenture Deed Poll.

Interest

Subordinated Debenture Interest

The Subordinated Debentures will pay interest ("Subordinated Debenture Interest") at a floating rate.

Subordinated Debenture Interest will be paid quarterly in arrears on 29 March, 29 June, 29 September and29 December of each year commencing on 29 December 2006 (each a "Subordinated Debenture InterestPayment Date"). The Subordinated Debenture Interest Payment Dates will match the LLC Note InterestPayment Dates in respect of the LLC Notes (so long as the NCIs are on issue).

The amount of each payment of Subordinated Debenture Interest will be calculated in accordance with therelevant formula set out in the Subordinated Debenture Terms, which, will equal the calculation of theLLC Note Interest on the LLC Notes (see Summary of Principal Documents—Terms of the LLC Notes—Interest above).

Subordinated Debenture Interest limitations, tests and conditions

A payment of Subordinated Debenture Interest is subject to the directors of National resolving to pay thatSubordinated Debenture Interest and the specific condition that no APRA Condition exists. Thecircumstances in which an "APRA Condition" will exist are set out in the NCI Terms (see Terms andConditions of the NCIs—Interpretation and Definitions—Definitions above). The APRA Conditions inrespect of the Subordinated Debentures will mirror the APRA Conditions in respect of the LLC Notes.

Subordinated Debenture Interest will be cumulative and, accordingly, any unpaid Subordinated DebentureInterest will accumulate. However:

(a) interest will not accrue on any unpaid amount of Subordinated Debenture Interest ("AccumulatedSubordinated Debenture Interest");

(b) National New York Branch is not permitted (unless approved by APRA) to pay any AccumulatedSubordinated Debenture Interest until the first Subordinated Debenture Interest Payment Datethereafter on which no APRA Condition exists and the other interest payment tests are met; and

(c) any Accumulated Subordinated Debenture Interest can never be distributed to NCI Holders, because,if the Assignment has occurred, National Head Office will be the holder of the LLC Notes and if theSubordinated Debentures are to be redeemed, National LLC 1 has irrevocably directed National NewYork Branch to pay the redemption amount to National Head Office (see further Summary ofPrincipal Documents—Terms of the LLC Notes—Assignment and Summary of Principal Documents—Terms of the LLC Notes—Redemption above).

Failure to pay in full, for any reason, Subordinated Debenture Interest on or within seven Business Days ofthe scheduled Subordinated Debenture Interest Payment Date, will ultimately result in the Issuer havinginsufficient funds to pay, in full, the corresponding Distribution scheduled to be paid on the correspondingDistribution Payment Date in respect of the NCIs and, accordingly, will trigger the Conversion Event (seeTerms and Conditions of the NCIs—Conversion). Failure to pay that corresponding Distribution in respectof the NCIs will also immediately trigger distribution restrictions for National as described in the Termsand Conditions of the NCIs—Distributions—Restrictions in the case of non-payment and, when thePreference Shares are issued, substantially in the form described in Summary of Principal Documents—Terms of the Preference Shares—Dividends—Distribution Restrictions below but it will not constitute an event

Additional Amounts

National New York Branch will make all payments of Subordinated Debenture Interest without deductionor withholding for, or on account of, tax unless that deduction or withholding is required by law.

an additional amount ("Additional Amount") to National LLC 1 (as holder of the SubordinatedDebentures) so that National LLC 1 receives the same amount in respect of that payment as if no suchdeduction had been made from the payment.

Capital Disqualification Event

If a Capital Disqualification Event (as described in the Terms and Conditions of the NCIs—CapitalDisqualification Event) occurs, Subordinated Debenture Interest will not be subject to the limitationsdescribed above under Summary of the Principal Documents—Terms of the Subordinated Debentures-Interest—Subordinated Debenture Interest limitations, tests and conditions and will be absolute andunconditional liabilities of National New York Branch on each Interest Payment Date.

Redemption

The holder of the Subordinated Debentures has no right to require the Subordinated Debentures to beredeemed.

At any time after the occurrence of the Assignment, the Subordinated Debentures may, subject to APRNsprior written approval, be redeemed by National New York Branch, in its sole discretion, at their FaceValue together with accrued interest (if any).

If the Subordinated Debentures are redeemed at any time after the Assignment, National LLC l'sobligation to pay to National Head Office (as Assignee) the Face Value and accrued interest onredemption of the LLC Notes will be satisfied by National New York Branch paying the Face Value and allaccrued interest (if any) payable on an equivalent number of Subordinated Debentures to National HeadOffice.

Liquidation

In the event of the dissolution, liquidation, termination or winding up of National, whether voluntary orinvoluntary, the holder of the Subordinated Debentures will be entitled to claim the Face Value plus any

62

accumulated and accrued interest on the Subordinated Debentures. Any such claim will rank senior to theclaims of the ordinary shares of National and pari passu with the claims of the holders of the ConvertibleDebentures, the Preference Shares (if they were issued) and NCI Holders under the NCI SubordinatedGuarantee and junior to the claims of all depositors and other creditors of National, other than creditorsexpressed to rank equally with, or junior to, the Subordinated Debentures.

Subject to APRNs prior written approval, National has the option to redeem:

• all (but not some) of the Convertible Debentures on the occurrence of a Regulatory Event, a TaxEvent or an Acquisition Event, and

63

• some or all of the Convertible Debentures on the Step-Up Date or any subsequent date which is aDistribution Payment Date in respect of the NCIs,

provided that where a Convertible Debenture remains on issue after the Conversion Date, the Issuer mayredeem the Convertible Debenture in the circumstances in which it would have been entitled to redeemthe Preference Shares had those Preference Shares been issued to or as directed by the holder of theConvertible Debentures on the Conversion Date.

"Regulatory Event", "Tax Event" and "Acquisition Event" are defined above in the definitions of the NCITerms (see Terms and Conditions of the NCIs Interpretation and Definitions—Definitions above).

• National is in liquidation;

• APRA has assumed control of National under the Banking Act and APRA does not cause National toissue the Preference Shares; or

• APRA has appointed a statutory manager under the Banking Act to take control of National'sbusiness and the statutory manager does not cause National to issue the Preference Shares.

64

Consequences of a failure to Issue Preference Shares

In the event that National fails to issue the Preference Shares when required to do so:

• the Assignment will still occur (see Summary of Principal Documents—Terms of the LLC Notes—Assignment above); and

• the Issuer will continue to hold the Convertible Debentures until National is no longer preventedfrom issuing the Preference Shares.

However, on and from the occurrence of the Conversion Event and for so long as the Issuer continues tohold the Convertible Debentures, the Issuer will be entitled, as holder of the Convertible Debentures:

• prior to the commencement of the winding up of National, to interest on the Convertible Debenturescalculated in the same manner and subject to the same tests and conditions as the payment ofdividends on the Preference Shares (see Summary of Principal Documents—Terms of the PreferenceShares—Dividends below), had they been issued; and

• in a winding up of National, to claim an amount in respect of the Convertible Debentures such thatthe Issuer recovers the same amount as it would have received if the Preference Shares had beenissued and were held by it.

Capital Disqualification Event

Notwithstanding the description of the Convertible Debentures in Summary of Principal Documents—Convertible Debentures—Conversion, if a Capital Disqualification Event occurs (as described in Terms andConditions of the NCIs—Capital Disqualification Event), the Convertible Debentures will not convert intoPreference Shares.

If a Capital Disqualification Event occurs, the Assignment (as described in Summary of PrincipalDocuments—Terms of the LLC Notes—Assignment above) will occur on the first to occur of the eventsdescribed in clause 5.2 (a) and (b) of the Terms and Conditions of the NCIs (the "Trigger Date").

On and from such Assignment Date, the Issuer shall continue to hold the Convertible Debentures and willbe entitled to interest on the Convertible Debentures ("Convertible Debentures Interest") until they areredeemed. Convertible Debentures Interest is payable in arrears on each Distribution Payment Date forthe NCIs at a rate equal to the rate payable on the NCIs on the corresponding Distribution Payment Date,subject only to the availability of sufficient retained earnings. Where the Assignment Date occurs on a datethat is not a Distribution Payment Date, the Convertible Debentures Interest will be calculated from theDistribution Payment Date in respect of the NCIs immediately preceding the Assignment Date (or if theAssignment occurs before the first scheduled Distribution Payment Date in respect of the NCIs, the issuedate in respect of the NCIs).

National will make all payments of Convertible Debentures Interest without deduction or withholding for,or on account of, tax unless that deduction or withholding is required by law. If any deduction is required,National must pay the full amount required to be deducted to the relevant revenue authority and, subjectto a demand being made for that amount by the Issuer (as holder of the Convertible Debentures) anadditional amount ("Additional Amount") to the Issuer as holder of the Convertible Debentures so thatthe Issuer receives the same amount in respect of that payment as if no such deduction had been madefrom the payment.

Voting and Other Rights

The Issuer (as holder of the Convertible Debentures) has no right to vote as a shareholder of Nationalunless and until the Preference Shares are issued, nor any right to vote on the management of National orany other National Entity.

The Issuer (as holder of the Convertible Debentures) will acknowledge in the Convertible DebentureTerms that a holder has no right to apply for any National Entity to be wound up, or placed inadministration, or to cause a receiver, or a receiver and manager, to be appointed in respect of a NationalEntity merely on the grounds that a National Entity does not pay a distribution or interest when scheduledunder any Component Instrument.

65

Liquidation

In the event of the dissolution, liquidation, termination or winding up of National, whether voluntary orinvoluntary, the Convertible Debentures will rank, without any preference amongst themselves, senior tothe claims of the ordinary shares of National and pari passu with the claims of the holders of the PreferenceShares which would have been issued if the Convertible Debentures had converted into Preference Shares,the Subordinated Debentures and the beneficiaries of the NCI Subordinated Guarantee and junior to theclaims of all depositors and other creditors of National, other than creditors expressed to rank equallywith, or junior to, the Convertible Debentures.

Amendments and Modifications

The Convertible Debenture Terms can be amended with the prior written approval of APRA (if required)but, in certain circumstances (see Description of the Issuer—Issuer LLC Agreement—Amendments andModifications above), without the consent of the NCI Holders or the Issuer (as holder of the ConvertibleDebentures). Any other amendment to the Convertible Debenture Terms will require a Special Resolutionof NCI Holders and the approval of the Issuer (as holder of the Convertible Debentures).

Without the consent of NCI Holders or the Issuer (as holder of the Convertible Debentures) Nationalmay, prior to the Conversion Date, amend the Convertible Debentures to provide for the issue ofPreference Shares on the terms described in the third paragraph of Summary of Principal Documents—Terms of the Preference Shares—Redemption.

No Set-Off or Offsetting Rights

The Issuer (as holder of the Convertible Debentures) has no right to set-off any amounts owing by it to anyNational Entity against any claims owing to it by any National Entity. The Issuer also has no offsettingrights or claims on any National Entity if a National Entity does not pay a distribution or interest whenscheduled under any Component Instrument.

Governing Law

The Convertible Debenture Deed Poll, the Convertible Debenture Terms and the Convertible Debentureswill be governed by, and construed in accordance with, English law.

Terms of the Preference Shares

General

The Preference Shares ("Preference Shares") will be issued on the occurrence of the Conversion Event,and will be fully paid preference shares in National, denominated in Euro, with a liquidation amount ofE50,000 ("Liquidation Amount"), corresponding to the NCIs being converted into the Preference Sharesthrough the conversion (see Summary of Principal Documents—Terms of the Convertible Debentures—Conversion above). National will bear the cost of any stamp duty on the issue of the Preference Shares.

The Preference Shares will rank pan passu among themselves in all respects and with all Equal RankingInstruments.

"Equal Ranking Instruments" means:

(a) the NIS preference shares;

(b) the ExCap preference shares (if issued);

(c) the 2003 trust preferred preference shares (if issued);

(d) the 2005 trust preferred preference shares (if issued);

(e) each other preference share that National may issue that is expressed to rank equally with theforegoing for returns of capital in a winding-up of National; and

(f) any securities or other instruments that are expressed to rank in a winding-up equally with thosepreference shares.

"NIS" means the income securities issued by National in 1999 comprising fully paid notes issued byNational through National New York Branch stapled to unpaid preference shares issued by National.

66

"NIS preference shares" means the preference shares issued by National in connection with the NIS which,if paid up in accordance with the terms of the NIS, will be outstanding in an aggregate liquidation amountof up to A$2.0 billion.

"ExCap preference shares" means the preference shares which may be issued by National in an aggregateliquidation amount of up to US$1.0 billion by National in connection with the ExCaps.

"ExCaps" means the exchangeable capital securities issued by National in 1997, each consisting of a capitalsecurity exchangeable in certain circumstances into ExCap preference shares or ordinary shares ofNational.

"2003 trust preferred securities" means the trust preferred securities issued by National Capital Trust I in2003 which are exchangeable for global depositary receipts, or "GDRs", each evidenced by a globaldepositary share, or "GDS", representing one 2003 trust preferred preference share.

"2003 trust preferred preference shares" means the preference shares which may be issued by National in anaggregate liquidation amount of up to £400 million by National in connection with the 2003 trust preferredsecurities.

"2005 trust preferred securities" means the trust preferred securities issued by National Capital Trust II in2005 which are exchangeable for 2005 trust preferred preference shares.

"2005 trust preferred preference shares" means the preference shares which may be issued by National in anaggregate liquidation amount of up to US$800 million by National in connection with the 2005 trustpreferred securities.

The terms of the Preference Shares will be approved by the directors of National (the "Preference ShareTerms") (see further General Information—Authorisation below).

Dividends

Dividends

The Preference Shares will pay dividends ("Dividends") at a floating rate.

Dividends on any Preference Shares issued will be paid quarterly in arrears on 29 March, 29 June,29 September and 29 December of each year (each a "Dividend Payment Date"). The Dividend PaymentDates will match the Distribution Payment Dates in respect of the NCIs.

The amount of each Dividend will be calculated in accordance with the relevant formula set out in thePreference Share Terms, which will substantially mirror the calculation of the Distributions on the NCIs(see Terms and Conditions of the NCIs—Distributions above). Where the Conversion Event occurs on adate that is not a Dividend Payment Date, the Dividend for the first Dividend Period will be calculatedfrom the Distribution Payment Date in respect of the NCIs immediately preceding the Conversion Date(or, if the Conversion Date occurs before the first scheduled Distribution Payment Date in respect of theNCIs, the issue date in respect of the NCIs).

Payment of a Dividend on the Preference Shares is subject to the directors of National resolving to pay theDividend and the specific condition that no APRA Condition exists. The APRA Conditions in respect ofthe Preference Shares will substantially mirror the APRA Conditions in respect of the NCIs (see Terms andConditions of the NCIs—Interpretation and Definitions—Definitions above).

Dividends will not be cumulative and the holder of a Preference Share (the "Preference Shareholder") willhave no claim for any Dividend not paid, or for any part of any Dividend not paid, pursuant to thelimitations on Dividends discussed above. Failure to pay in full, for any reason, Dividends on the scheduledDividend Payment Date, will trigger distribution restrictions for National (see Summary of PrincipalDocuments—Terms of the Preference Shares—Dividends—Distribution Restrictions below) but it will notconstitute an event of default and it will not entitle the Preference Shareholders to take any other action,including, for example, to require that the Preference Shares be redeemed.

Additional Amounts

National will make all payments of Dividends without deduction or withholding for, or on account of, taxunless that deduction or withholding is required by law. If any deduction is required, National must pay thefull amount required to be deducted to the relevant revenue authority and, subject to certain exceptions(which will substantially mirror the exceptions in the NCI Terms (see Terms and Conditions of the NCIs-

67

Payments to NCI Holders—Gross-up above)), an additional amount ("Additional Amount") to PreferenceShareholders so that each Preference Shareholder receives the same amount in respect of that payment asif no such deduction had been made from the payment.

Distribution Restrictions

National's ability to pay distributions will be restricted if:

• National fails to pay in full, on any Dividend Payment Date, the accrued dividends on the PreferenceShares for the relevant Dividend Period; or

• a Conversion Event has occurred as a result of any failure by the Issuer to pay in full the distributionpayable on the NCIs on any Distribution Payment Date;

then, unless approved by the Preference Shareholders by ordinary resolution, National may not:

(a) pay any interest, dividends or similar distributions on any other capital instruments of National whichrank for dividends equal with, or junior to, the Preference Shares; or

(b) redeem, buy-back or reduce capital on any other capital instruments of National which rank for returnof capital in a winding up, equal with, or junior to, the Preference Shares,

subject to certain limited exceptions (which will substantially mirror the exceptions to the distributionrestriction in the NCI Terms (see Terms and Conditions of the NCIs—Distributions—Exceptions torestrictions above)).

The distribution restrictions will remain in force until National has paid in full:

(a) consecutive dividends on the Preference Shares on each Dividend Payment Date during the 12 monthperiod following the non-payment of the Dividend; or

(b) with APRiVs prior written approval, an optional dividend equal to the unpaid amount of thescheduled dividends, or distributions on the Preference Shares or NCIs, for the period of 12 monthsprior to the date of payment of the optional dividend ("Optional Dividend").

Redemption

A Preference Shareholder has no right to require a redemption or buy-back of, or reduction of capital on,the Preference Shares.

Subject to APRNs prior written approval, National has the option to redeem, buy-back or reduce capital(in such combination as National may determine) on:

• all (but not some) of the Preference Shares on the occurrence of a Preference Share Event (as definedbelow) or the issuance of Preference Shares (provided that the Conversion Event giving rise to theissue of the Preference Shares did not result from National exercising its discretionary right to causethe Conversion Event to occur); or

• some or all of the Preference Shares on the Step-Up Date or any subsequent Dividend Payment Date.

Pursuant to the Convertible Debenture Terms (as described in Summary of Principal Documents—Terms ofthe Convertible Debentures—Amendment and Modification) National may, prior to the issue of thePreference Shares, elect that it issue Preference Shares on terms that it does not have the option to redeemthose Preference Shares (but without limiting its rights to buy-back or reduce capital on such PreferenceShares, in such combination as it may determine and otherwise on the same terms as the Preference Sharesdescribed in Summary of Principal Documents—Terms of the Preference Shares below).

A Preference Share Event ("Preference Share Event"), occurs in circumstances where an AcquisitionEvent, a Regulatory Event or a Tax Event occurs.

For these purposes, "Acquisition Event" and "Regulatory Event" will have a substantially similar definitionto those defined above in the Definitions of the Terms and Conditions of the NCIs (see Terms andConditions of the NCIs—Interpretation and Definitions—Definitions above).

"Tax Event" means that, on or after the Issue Date of the NCIs, National receives an opinion from areputable legal counsel or other tax adviser in Australia, the United States, the United Kingdom or New

68

Zealand or any other jurisdiction (each a "Relevant Jurisdiction"), experienced in such matters that thereis more than an insubstantial risk that, as a result of a 'Fax Law Change:

(a) there is a requirement to gross-up any Dividend on the Preference Shares; or

(b) National would be exposed to more than a de minimis amount of other taxes, assessments or othergovernmental charges in connection with the Preference Shares.

"Tax Law Change" will have a substantially identical definition to that set out under the Terms andConditions of NC's Interpretation and Definitions—Definitions above.

The Redemption Price payable on each Preference Share redeemed will equal the Redemption Price thatwould have been payable on the redemption of the corresponding NCI (see Terms and Conditions of theNCIs—Redemption--Redemption Price above).

Voting and Other Rights

Voting

Generally, the Preference Shareholders will not be entitled to vote at a general meeting of National.However, they may vote together with holders of ordinary shares in National:

• on any resolution to wind up National, or during the winding up of National;

• on any resolution to reduce National's share capital (except a reduction of capital in accordance withthe Preference Share Terms);

• on any resolution to approve the terms of a buy-back agreement (except a buy-back in accordancewith the Preference Share Terms);

• on any resolution that National dispose of all of its business, property and undertaking; and

• during a Special Voting Period (as defined below), with respect to all matters on which the holders ofordinary shares are entitled to vote, other than on a resolution to approve a Redemption.

They may also vote as a class on any resolution to vary the rights attaching to Preference Shares.

In any such case Preference Shareholders will have one vote per Preference Share.

"Special Voting Period" means the period from (and including):

(a) any Dividend Payment Date on which National does not pay in full the Dividends calculated in respectof the Preference Shares for the immediately preceding Dividend Period; or

(b) the 22nd Business Day after the Conversion Event occurs if the Conversion Event occurred as a resultof non-payment of a Distribution on the NCIs unless prior to such date National has paid in full anOptional Dividend,

in each case to (but not including) the first Dividend Payment Date after that date on which National haspaid an Optional Dividend in accordance with the provisions of Preference Share Terms or has paid in fullthe Dividends scheduled to be payable on the Preference Shares during a period of 12 consecutivecalendar months.

The Preference Share Terms provide that a Preference Shareholder has no right to apply for National to bewound up, or placed in administration, or to cause a receiver, or a receiver and manager, to be appointedin respect of National merely on the grounds that National does not pay a Dividend when scheduled underthe Preference Shares.

Restrictions on Ownership and Transfer

The acquisition of shares in Australian public companies listed on the Australian Stock Exchange ("ASX")is regulated by detailed and comprehensive legislation and the rules of the ASX. Legislation also affectsthe offer of shares for sale in certain circumstances.

One of the most common manners in which a controlling shareholding is acquired in an Australian listedcompany is by a takeover bid. The form and content of the bid documentation is regulated by law.Australian takeover law purports to have extra-territorial force. Australian law may therefore apply to atransaction outside Australia with respect to a non-Australian company if the transaction affects thecontrol of voting power in an Australian publicly listed company.

69

Australian law also regulates the acquisition of shares in Australian corporations by foreign persons underthe Foreign Acquisitions and Takeovers Act 1975 ("Takeovers Act"). The Takeovers Act empowers theAustralian Treasurer to prohibit a proposed acquisition of shares in an Australian corporation where theresult of the acquisition will be that a foreign person (together with its associates) would have an interest ofnot less than 15% of the issued shares of a corporation, or two or more foreign persons (together with theirassociates) would in aggregate have an interest in 40% of the issued shares of the corporation that has totalassets valued at A$50,000,000 or more, such as National. In addition, the Takeovers Act requires foreignpersons who propose to make such acquisitions to first notify the Australian Treasurer of their intention todo so. Failure to notify the Treasurer of a proposed acquisition is an offence under the Takeovers Act.Where such an acquisition has already occurred without notice having been given, the Australian Treasurerhas the power to order a person that acquired the shares to dispose of them. The concepts of acquisition,interest, associate and foreign person are very widely defined in the Takeovers Act and investors shouldseek their own advice on the application of the Takeovers Act to them.

Australian law also regulates acquisitions of shares in Australian companies which would have the effect,or be likely to have the effect, of substantially lessening competition in a market in Australia, or in a stateor territory thereof, under the Trade Practices Act 1974. Investors should seek their own advice on theapplication of the Trade Practices Act 1974.

There are also restrictions placed upon shareholdings in Australian banks generally under the Financial(Shareholdings) Act 1998 (the "FSSA"). Under the FSSA, the Australian Treasurer's prior approval isrequired before any person may acquire shares in an authorised deposit-taking institution, of whichNational is one, in Australia where the acquisition would take that person's stake in that institution tomore than 15% (see Description of National—Major Shareholders above). A person's stake relates to thedirect control interest of that person or its associates in the shares of a company. The concepts of "stake","direct control interests", "voting power", "associates" and "shares" are broadly defined in the FSSA andinvestors should seek their own advice on the application of the FSSA.

Takeover and Substantial Shareholder Provisions

Generally, the Corporations Act prohibits a person from acquiring a "relevant interest" in the votingshares in a listed company (such as National) if that person's or someone else's "voting power" in thecompany increases from 20%, or from a starting point that is above 20% and below 90%, unless thoseshares are acquired in a manner specifically permitted under an exception. The exceptions in theCorporations Act are limited and include, for example, an acquisition previously consented to by theshareholders of the company, or an acquisition made under a court-approved scheme. Generally, theconcept of a voting share does not include certain types of preference shares with limited voting rights.However, because Preference Shareholders have been conferred a right to vote following the failure to paya Dividend (see Summary of Principal Documents—Terms of the Preference Shares—Voting and OtherRights—Voting above), the Preference Shares will be treated as voting shares under the Corporations Act.Therefore any person considering the acquisition of the NCIs should consider the effect on their orsomeone else's "voting power" which will arise upon the issue to them of Preference Shares following theConversion Event and should seek appropriate advice in the context of the regulatory thresholdssummarized under this section.

The concepts of "relevant interest", and "associates" and "acquire" are very broadly defined and investorsshould seek their own advice on the application of the Corporations Act. In very general terms:

• a person's voting power ("voting power") equals the total number of votes attached to the votingshares in which the person and their associates have a relevant interest ("relevant interest") (which isbasically where they hold, or have or control the exercise, of the right or power to vote or dispose ofthe shares), expressed as a percentage of all the voting shares in the company, but there are additionalinclusions and certain exceptions;

• a person acquires ("acquires") shares in a company if, as a direct or indirect result of a transaction inrelation to securities of any body corporate, that person acquires a relevant interest in those sharesand, as a result of extensive tracing provisions concerning relevant interest, a person may be taken tohave acquired National's shares for example as a result of the purchase of securities in another bodycorporate if that body corporate holds, or acquires, a relevant interest in National's shares; and

• an associate ("associate") (the "second person") of the primary person is widely defined in Division 2of Part 1.2 of the Corporations Act and includes, among others, a body corporate the primary person

70

controls, a body corporate that controls the primary person, or a body corporate that is controlled byan entity that controls the primary person as well as persons acting, or agreeing or proposing to agreeto act in concert in relation to the listed company's affairs.

The Corporations Act also obliges persons who begin to have, or cease to have a substantial holding in alisted company (being a relevant interest of that person, or their associates, in 5% or more of the votingshares of the company), or whose substantial holding moved at least 1%, to give notice to the company andto the ASX of their substantial shareholdings and such movements.

Amendments and Modifications

The Preference Share Terms and the rights attaching to the Preference Shares may be amended ormodified with the sanction of a Special Resolution passed at a meeting of the Preference Shareholders.

The Preference Share Terms can also be amended or modified with the prior written approval of APRA (ifrequired) but without the consent of Preference Shareholders in certain circumstances (which substantiallymirror the circumstances in which the NCI Terms may be amended or modified without the consent ofNCI Holders (see Description of the Issuer—Issuer LLC Agreement—Amendment and Modification above)).

The rights attaching to the Preference Shares will not be deemed to be varied by the creation or issue ofany further preference shares ranking equal with, junior to, or senior to, the Preference Shares and thecreation of such preference shares will be expressly permitted by the Preference Share Terms.

Liquidation

In the event of the dissolution, liquidation, termination or winding up of National, whether voluntary orinvoluntary, the Preference Shares will rank:

• senior to the claims of the ordinary shares of National and pan passu with the claims of the holders ofthe classes of preference shares of National with the same ranking identifying number as provided inNational's constitution; and

• junior to all depositors and other creditors, other than creditors whose claims are expressed to rankpan passu with the Preference Shares.

No Set-Off or Offsetting Rights

A Preference Shareholder has no right to set off any amounts owing by it to National against any claimsowing to it by National. The Preference Shareholder also has no offsetting rights or claims on National ifNational does not pay a Dividend when scheduled under the Preference Shares.

Governing Law

The Preference Share Terms and the Preference Shares will be governed by, and construed in accordancewith, the laws of the State of Victoria.

Terms of the Deed of Covenant

General

In order to give effect to the terms of the NCIs, National, National LLC 1 and the Issuer have entered intoa deed of covenant (the "Deed of Covenant") under which the parties have agreed to give certainundertakings on the terms set out in the Deed of Covenant.

Undertakings by National

National undertakes to the Issuer and National LLC 1 (each a "Relevant Party") (among other things) to:

• to meet the expenses of each Relevant Party;

• pay, subject to the tests and conditions set out in the Subordinated Debenture Terms (see Summary ofPrincipal Documents—Terms of the Subordinated Debentures—Interest above), each other RelevantParty for any Additional Amounts it is required to pay in accordance with the terms of the relevantComponent Instrument;

• indemnify each Relevant Party for any liabilities incurred in relation to the Capital Instrument;

71

• comply with National's obligations with respect to distribution restrictions in the case of non-paymenton the NCIs (see Terms and Conditions of the NCIs—Distributions—Restrictions in the case ofnon-payment above);

• comply with all other things which are specified in the Component Instruments to be done or not doneby National; and

• to do all other things which are necessary to be done by National to enable the Relevant Party tocomply with its obligations under the Component Instruments to which it is a party.

National's role under the Deed of Covenant

Notwithstanding the provisions described above:

• National's obligations to the Relevant Parties in connection with the Deed of Covenant are not andshould not be construed as a guarantee by National of any obligations of a Relevant Party in relationto any Component Instrument or that any payment scheduled to be made under a ComponentInstrument will be made; and

• the Deed of Covenant does not confer on any NCI Holder a right to take action against any NationalEntity to enforce payment of any amounts payable by that entity under the Deed of Covenant or toclaim damages for breach of any obligation under the Deed of Covenant.

Governing Law

The Deed of Covenant will be governed by, and construed in accordance with, English law.

72

USE OF PROCEEDS

The proceeds of issue of the NCIs will be used by the Issuer to purchase the LLC Notes and theConvertible Debentures from the Initial Subscriber. Prior to that, the Initial Subscriber will havesubscribed for the LLC Notes and the Convertible Debentures and will have received from National HeadOffice the Assignment Payment.

National LLC 1 will use the proceeds from the sale of the LLC Notes to subscribe for the SubordinatedDebentures issued by National New York Branch. The proceeds of issue of the Subordinated Debentureswill be used by National New York Branch for its general business purposes including the lending of theproceeds to branches or entities within the National Group or the acquisition of debt securities issued byentities within the National Group.

73

TAXATION

This section summarises the principal United States and Australian taxation consequences and certain EUtaxation consequences arising from the acquisition, holding and disposal of NCIs by NCI Holders who holdtheir NCIs on capital account for tax purposes.

The summary is based on tax law and practice in force as at the date of this Prospectus, unless otherwiseindicated. It is of a general nature only and is neither exhaustive nor definitive and it does not purport to be acomplete analysis of all of the tax considerations relating to the NCIs or the Preference Shares (if issued). Thesummary does not apply to NCI Holders who hold NCIs on revenue account, as trading stock or as part of asecurities trading business and may not apply to certain other classes of persons. It is not intended to be adviceand should not be relied upon as such.

Prospective holders of NCIs should seek independent taxation advice having regard to their own particularcircumstances before making a decision to invest in NCIs.

Certain United States Federal Income Tax Consequences to Non-U.S. Holders

This section summarises the material U.S. federal income tax consequences of the acquisition, ownershipand disposition of the National Capital Instruments (NCIs) by a non-U.S. holder (as defined below). Itapplies to an NCI Holder only if the NCI Holder acquires the NCIs in this offering and holds the NCIs ascapital assets for tax purposes.

This section is based on the Internal Revenue Code of 1986, as amended (the "Code"), its legislativehistory, existing and proposed regulations, published rulings and court decisions, all as currently in effect.These laws are subject to change, possibly on a retroactive basis. This section does not address any aspectsof state, local, foreign or other tax laws.

To ensure compliance with IRS Circular 230 disclosure requirements imposed by the IRS, the Issuerinforms each NCI Holder that (i) any U.S. tax advice contained in this communication (including anyattachments) is not intended or written to be used, and cannot be used, for the purpose of avoiding penaltiesunder the Internal Revenue Code and (ii) any such tax advice is written in connection with the promotion ormarketing of the matters addressed.

A NCI Holder is a "non-U.S. holder" if the NCI Holder is a beneficial owner of NCIs and is not: (i) acitizen or resident of the United States for U.S. federal income tax purposes, (ii) a corporation or apartnership (including an entity treated as a corporation or a partnership for U.S. federal income taxpurposes) created or organized in or under the laws of the United States, any state thereof or the Districtof Columbia, (iii) an estate whose income is subject to U.S. federal income tax regardless of its source, or(iv) a trust if (a) a court within the United States is able to exercise primary supervision over theadministration of the trust and one or more U.S. persons have the authority to control all substantialdecisions of the trust or (b) it has a valid election in effect under applicable Treasury regulations to betreated as a U.S. person.

Special rules may apply to certain non-U.S. holders, such as "controlled foreign corporations," "passiveforeign investment companies," foreign partnerships, foreign estates or foreign trusts having a beneficiarythat is a U.S. person, corporations that accumulate earnings to avoid U.S. federal income tax, persons thatactually or constructively own 10% or more of the voting stock of National, and persons that are subject tospecial treatment under the Code. These persons should consult their own tax advisors to determine theU.S. federal, state, local and other tax consequences that may be relevant to them.

Classification of Subordinated Debentures and the NCIs

Although there is no statutory, judicial or administrative authority that directly addresses the US federalincome tax treatment of an issuance of securities similar to the Subordinated Debentures and the NCIs,the Subordinated Debentures and the NCIs should be treated as equity of National for US federal incometax purposes. National, National LLC 1, the Issuer and the holders of the NCIs (by acquiring NCIs in thisoffering) will agree to treat the Subordinated Debentures and the NCIs as equity of National for suchpurposes and the discussion below assumes that the Subordinated Debentures and NCIs will be so treated.

74

US federal income tax and withholding tax on NCIs

Subject to the discussion of backup withholding below, a non-U.S. holder will not be subject to U.S. federalincome tax, including withholding tax, on any income in respect of the NCIs, or on any gain realised by thenon-U.S. holder on the sale or exchange of NCIs unless (i) such income or gain is effectively connectedwith the conduct of a trade or business by the non-U.S. holder in the United States or (ii) in the case ofgain realised by an individual non-U.S. holder, the non-U.S. holder is present in the United States for183 days or more in the taxable year and certain other conditions are met.

Information reporting and backup withholding may apply to payments made on and proceeds from the saleof the NCIs unless the non-U.S. holder complies with applicable certification procedures to establish that itis not a U.S. person for U.S. federal income tax purposes.

Certain Australian Tax Consequences

General

The discussion below outlines certain Australian taxation consequences of the acquisition, ownership anddisposition of a beneficial interest in NCIs and Preference Shares (if issued upon the occurrence of aConversion Event). The discussion is based upon laws, regulations, rulings and judicial decisions now ineffect and is subject to future change. This discussion is intended only as a descriptive summary and doesnot purport to be a complete technical analysis or to list all potential Australian tax consequences. It is notintended to be advice and should not be relied upon as such.

This summary assumes that the holder of a beneficial interest in NCIs and Preference Shares (whereissued) (a) will not be a "resident" of Australia for Australian income tax purposes; and (b) will not holdthe beneficial interest in NCIs or Preference Shares as part of a business carried on by that holder at orthrough a permanent establishment in Australia ("Non-resident Holder").

Persons considering the purchase of a beneficial interest in NCIs should consult their own tax advisorsconcerning the application of Australia's tax laws to their particular situations as well as any consequencesof the acquisition, ownership and disposition of a beneficial interest in NCIs or the Preference Sharesunder the laws of any other taxing jurisdiction.

NCIs

Status of the Issuer

The Issuer, a limited liability company formed under the laws of Delaware in the United States, will not betreated as a resident of Australia for Australian income tax purposes.

Distributions on NCIs

Non-resident Holders will only be subject to Australian income tax on so much of their income as has anAustralian source. Distributions on the NCIs would be regarded as having a foreign source. Accordingly,Distributions on the NCIs will not be subject to Australian income tax in the hands of Non-residentHolders, either by withholding or otherwise.

Disposal; redemption or conversion of NCIs

Under current law, non-residents may be subject to Australian capital gains tax on the disposal of certaintypes of assets having the necessary connection with Australia. A beneficial interest in NCIs would nothave the necessary connection with Australia. Accordingly, Non-resident Holders should not be subject toAustralian capital gains tax on the disposal, redemption or conversion of a beneficial interest in NCIs.

Preference Shares

Dividends paid on the Preference Shares

Dividends paid by National on the Preference Shares may be either franked or unfranked. Broadly, to theextent to which those dividends are paid out of profits which have been subject to Australian corporateincome tax, they will be franked dividends. Fully franked dividends paid to a Non-resident Holder will beexempt from Australian dividend withholding tax. Unfranked or partially franked dividends will be subjectto Australian dividend withholding tax at a rate of 30% to the extent to which the dividend is unfranked,

75

unless a double tax agreement between Australia and the particular country in which the Non-residentHolder resides reduces that rate.

Disposal of Preference Shares

Under current law, Non-resident Holders should not be subject to Australian capital gains tax on a disposalof a beneficial interest in Preference Shares provided, at the time of disposal, they, together with theirassociates, have not beneficially owned at least 10% or more by value of the ordinary shares in National atany time during the preceding five years.

Recently released Tax Laws Amendment (2006 Measures No. 4) Bill 2006 proposes to amend Australia'stax legislation, such that Australian capital gains tax will no longer have application to non-residents inrespect of assets such as the Preference Shares (that are not held through an Australian permanentestablishment) under any circumstances. The amendments are proposed to take effect for disposalsoccurring on or after the date the Bill receives Royal Assent.

GST and stamp duty

No GST or stamp duty should apply to the issue, disposal, redemption or conversion of a beneficialinterest in NCIs or Preference Shares (as applicable).

EU Savings Tax Directive

Under EC Council Directive 2003/48/EC on the taxation of savings income, each Member State isrequired, from 1 July 2005, to provide to the tax authorities of another Member State details of paymentsof interest or other similar income paid by a person within its jurisdiction to, or collected by such a personfor, an individual resident in that other Member State; however, for a transitional period, Austria, Belgiumand Luxembourg may instead apply a withholding system in relation to such payments, deducting tax atrates rising over time to 35%. The transitional period is to terminate at the end of the first full fiscal yearfollowing agreement by certain non-EU countries to the exchange of information relating to suchpayments.

Also with effect from 1 July 2005, a number of non-EU countries, and certain dependent or associatedterritories of certain Member States, have agreed to adopt similar measures (either provision ofinformation or transitional withholding) in relation to payments made by a person within its jurisdiction to,or collected by such a person for, an individual resident in a Member State. In addition, the Member Stateshave entered into provision of information or transitional withholding arrangements with certain of thosedependent or associated territories in relation to payments made by a person in a Member State to, orcollected by such a person for, an individual resident in one of those territories.

The partners of the Issuer's auditors are typicallymembers of the Institute of Chartered Accountants of Australia, but the firm itself is not a member.

The auditors of National up to and including the year ended 30 September 2004 were KPMG, independentauditors, who had audited National's accounts, without qualification, in accordance with generallyaccepted auditing standards in Australia for the financial year ended 30 September 2004.

Similar limitations areexpected to become operative in the other states of Australia in the near future after the recent passage ofenabling legislation. The scope of the limitations and their effect on the enforcement of foreign judgmentsin Australia are so far untested.
