    A number of issues affect the data quality of statistical information based on claims data, as

    provided by the Department of Mines, Industry Regulation and Safety (DMIRS). It is important to

    be aware of these issues when interpreting claims statistics, to ensure that the conclusions

    drawn from the information take into account known inconsistencies and omissions.

    More information about the data can be found in the Explanatory notes section at the end of this

    report.

    2018 Data Note Due to re-benchmarking of Labour Force estimates based on revisions to the Estimated Resident

    Population following the 2016 census; denominator data (total number of employees covered by

    workers’ compensation and total number of hours worked) provided by the Australian Bureau of

    Statistics (ABS) in 2018 include data revisions for 2014–15 and 2015–16.

    Workers’ compensation claims data has been revised back to 2000–01.

    The revisions have affected rate calculations and caution is advised for all reported rates. As

    such, incidence and frequency rates may differ from previous publications in respect to these

    years and should not be used. Revised data is denoted by ‘r’.

    In 2012–13, one LTI/D was recorded per 78 employees in the Education and Training division;

    this figure has declined slightly to one LTI/D in every 75 employees during 2016–17p, although

    an improvement than the one in 86 employees recorded in 2014-15. The number of employees

    (those who are covered by workers’ compensation) in this industry increased one per cent to

    104,093 during 2016–17 compared to 2012–13 figures. All LTI/D categories recorded above the

    five year division average during 2016–17p.

    The total estimated cost per LTI/D during 2012–13 was $31,352 increasing slightly to an

    estimated $32,804 per LTI/D in 2015–16. Preliminary data for 2016–17 suggest costs are

    currently the lowest in the reporting period; however this figure is expected to rise as claims data

    mature.

    The frequency rate for LTI/Ds of one or more days/shifts lost from work has reduced by

    2.2 per cent during 2016–17p compared to 2012–13; whereas the incidence rate has increased

    4.5 per cent over the same period. All LTI/D categories report increases in respect to incidence

    rate over the five year period. In respect to frequency rate, serious LTI/Ds (five days/shifts or

    more lost from work) and severe LTI/Ds (60 days/shifts or more lost from work) recorded

    respective increases of 7.6 and 19.8 per cent.

  • Work-related lost time injuries and diseases in Western Australia 2012–13 to 2016–17p 6 Education and Training Industry Profile (ANZSIC 2006)

    During the five year reporting period, the Tertiary Education subdivision recorded reductions in

    the frequency and incidence rate of LTI/Ds of 17.9 and 19.4 per cent respectively. Rates are

    above the subdivision average for the first time in four years. The number of employees (those

    covered by workers’ compensation) and total hours worked respectively decreased 9.7 per cent

    (to 24,809 employees) and 11.3 per cent over the same period.

    Severe LTI/Ds (60+ days/shifts lost) are currently above the subdivision average and at the

    highest level recorded in the reporting period.

    The subdivision of Adult, Community and Other Education accounts for the least amount of

    LTI/Ds in the Education and Training industry division. Frequency and incidence rates decreased

    30.5 and 30.6 per cent respectively during 2016–17p compared to 2012–13. Rates have

    remained below the subdivision average for the last two years. The total number of employees

    covered by workers’ compensation has risen 44.1 per cent to 16,349 in 2016–17 comparative to

    2012–13 figures (although down from the high of 17,669 recorded in 2015–16) and the total

    hours worked increased 43.8 per cent. These are the highest increases of all three subdivisions

    and may have had an effect on the marked reductions in rates.

    Sex

    The distribution of LTI/Ds (1+ days/shifts lost) between male and female in this industry division

    has changed by four percentage points between 2012–13 and 2016–17p with the majority

    proportion of female LTI/Ds increasing over male LTI/Ds.

    The distribution of employees between male and female in 2012–13 has changed by three

    percentage points when compared to 2016–17 and continues to demonstrate a higher

    representation of female employees than male.

    The distribution of female LTI/Ds is in line with female employees in 2012–13. However in

    2016–17p, female LTI/Ds did not decrease in line with the proportion of female employees; in

    fact they increased disproportionately meaning there were more female work-related LTI/Ds

    recorded by fewer female employees in 2016–17 and may suggest multiple incidents for some

    female employees.

    The situation is inversed regarding the male distribution. The distribution of male LTI/Ds is

    marginally higher than male employees in 2012–13; whereas a more desirable situation is

    evident in 2016–17 with fewer LTI/Ds than employees.

    Occupation

    The three most common sub-major occupation groups (in order of magnitude) in Western

    Australia that experienced a workplace injury or disease of one or more days/shifts lost during

    the five year period from 2012–13 to 2016–17p are the Education Professionals group with 2,375

    LTI/Ds, primarily the occupations of Secondary School Teacher with 979 LTI/Ds (up two from

    192 in 2012–13 to 194 in 2016–17p), Primary School Teacher with 917 LTI/Ds (-12.4 per cent

    from 201 to 176), and Special Needs Teacher with 126 LTI/Ds (up 109.5 per cent from 21 to 44,

    the highest level in the five year period); the Carers and Aides group with 1,895 LTI/Ds, mainly

    Teachers’ Aide with 1,807 LTI/Ds (up 33.7 per cent from 329 to 440, the highest level in the five

    year period) and Aboriginal and Torres Strait Islander Education Worker with 29 LTI/Ds (from

  • Work-related lost time injuries and diseases in Western Australia 2012–13 to 2016–17p 8 Education and Training Industry Profile (ANZSIC 2006)

    Service Workers (up 33.8 per cent from 364 LTI/Ds in 2012–13 to 487 in 2016–17p), Managers

    (up 31.4 per cent from 35 to 46 LTI/Ds), and Clerical and Administrative Workers (up two LTI/Ds

    from 68 to 70).

    Four major groups recorded a reduction in LTI/Ds over the five year reporting period. The

    greatest reductions occurred in the groups accountable for the least numbers of LTI/Ds, being

    Sales Workers and Machinery Operators and Drivers (-50 and 57.1 per cent respectively). The

    Labourers group followed with -26.9 per cent (from 201 LTI/Ds in 2012–13 to 147 in 2016–17p)

    and Technicians and Trades Workers (-19.9 per cent from 146 to 117 LTI/Ds).

    In terms of severe LTI/Ds (LTI/Ds 60+ days/shifts lost from work), table 5 shows the highest

    recording occupations during the combined five year period from 2012–13 to 2016–17p. These

    occupations collectively account for more than two-thirds of total severe cases in this industry

    division.

    The occupation of Teachers’ Aide alone accounts for almost a quarter of all severe LTI/Ds in this

    industry division (24 per cent).

    Nature of injury

    The nature of injury/disease is intended to identify the most serious injury or disease sustained

    by the worker.

    The three most common natures of injury and disease (in order of magnitude) in relation to

    workplace injuries or diseases of one or more days/shifts lost during the five year period from

    2012–13 to 2016–17p are Soft tissue injuries due to trauma or unknown mechanisms with 2,340

    LTI/Ds (-21.7 per cent from 493 in 2012–13 to 386 in 2016–17p); Contusion, bruising and

    superficial crushing with 854 (up 100 per cent from 129 to 258), and Trauma to muscles and

    tendons, unspecified with 743 (up 28.9 per cent from 159 to 205).

    Other notable increases are evident for Anxiety/stress disorder (up 87.2 per cent from 39 LTI/Ds

    in 2012–13 to 73 in 2016–17p), Superficial injury (up 64.7 per cent from 17to 28), and Other

    intracranial injury, not elsewhere classified (up 39.1 per cent from 23 to 32), Bursitis (up 100 per

    cent from six to 12), and Occupational overuse syndrome (from

    Chart 4: Frequency rates by nature of injury

    In terms of severe LTI/Ds (LTI/Ds 60+ days/shifts lost from work), table 6 shows the highest

    recording nature of injury subgroups during the combined five year period from 2012–13 to

    2016–17p. These subgroups collectively account for 79 per cent of total severe cases in this

    industry division.

    Severe cases of Soft tissue injuries due to trauma or unknown mechanisms alone account for

    39 per cent of the total cases recorded during 2012–13 to 2016–17p.

    Contusion, bruising and superficial crushing 103 7%

    Total 1,178 79%

    Mechanism of incident The mechanism of incident is intended to identify the overall action, exposure or event that best

    describes the circumstances that resulted in the most serious injury/disease.

    The three most common mechanisms of incident (in order of magnitude) in relation to workplace

    injuries or diseases of one or more days/shifts lost during the five year period from 2012–13 to

    2016–17p are Falls on the same level with 1,866 LTI/Ds (up 4.7 per cent from 379 in 2012–13 to

    397 in 2016–17p), Muscular stress while handling objects other than lifting, carrying, or putting

    down with 858 LTI/Ds (-32.9 per cent from 213 to 143), and Being assaulted by a person or

    persons with 623 LTI/Ds (up 169 per cent from 11 LTI/Ds in 2012–13 to 191 in 2016–17p).

    LTI/Ds associated with the classification Falls on same level accounted for 28 per cent of all

    LTI/Ds recorded in the Education and Training industry division during 2016–17p.

    Notable increases also occurred in the subgroups of Contact with or exposure to biological

    factors of human origin (from zero LTI/Ds in 2012–13 to eight in 2016–17p), Exposure to a

    traumatic event (from

    Breakdown agency of injury The breakdown agency is intended to identify the object, substance or circumstance that was

    principally involved in, or most closely associated with, the point at which things started to go

    wrong and which ultimately led to the most serious injury/disease.

    The three most common breakdown agency of injury groups (in order of magnitude) in relation to

    workplace injuries or diseases of one or more days/shifts lost during the five year period from

    2012–13 to 2016–17p are the Environmental agencies group with 2,066 LTI/Ds, particularly the

    subgroups of Traffic and ground surfaces other with 678 LTI/Ds (up 7.6 per cent from 132 in

    2012–13 to 142 in 2016–17p) and Other internal traffic and ground surfaces with 280 LTI/Ds

    (down four LTI/Ds from 64 to 60); the Non powered handtools, appliances and equipment group

    with 1,508 LTI/Ds, commonly Sporting equipment with 211 LTI/Ds (-35.4 per cent from 48 to 31)

    and Sitting furniture with 196 LTI/Ds (down one LTI/D from 42 to 41); and the Animal, human and

    biological agencies group with 1,234 LTI/Ds, primarily the subgroup of Other person with 1,153

    LTI/Ds (up 58.4 per cent from 190 to 301, the highest level in the reporting period).

    The chart below represents frequency rates of work-related lost time injuries and diseases by

    breakdown agency groups in relation to the Education and Training industry division.

    Reductions in frequency rate are evident in six groups during the five year period. The largest

    reductions were recorded in the groups of Powered equipment tools and appliances at

    -36.9 per cent (from 0.58 LTI/Ds per one million hours worked in 2012–13 to 0.36 in 2016–17p).

    This was followed by Non powered handtools appliances and equipment group (-20.5 per cent

    from 2.43 to 1.93) and the Chemicals and chemical products group (-20.3 per cent from a rate of

    0.05 to 0.04).

    Three breakdown agency of injury groups recorded an increase in frequency rate in the five

    years to 2016–17p. The Animal human and biological agencies group recorded a 47.5 per cent

    increase from 1.40 LTI/Ds per one million hours worked in 2012–13 to 2.06 in 2016–17p;

    followed by Machinery and mainly fixed plant (up 47.2 per cent from 0.08 to 0.12) and

    Environmental agencies (up 4.1 per cent from 2.75 to 2.87).

    Bodily location

    The bodily location is intended to identify the part of the body affected by the most serious

    injury/disease sustained by the worker.

    The three parts of the body most affected (in order of magnitude) in relation to workplace injuries

    or diseases of one or more days/shifts lost during the five year period from 2012–13 to 2016–17p

    are the Lower back with 687 LTI/Ds (-6.3 per cent from 143 in 2012–13 to 134 in 2016–17p),

    Knee with 649 (up one LTI/D from 138 to 139), and Ankle with 490 (-17.4 per cent from 109 to

    90).

    Other areas of the body to record notable increases over the five year period include the Chest

    muscles (from

    Over the five year period increases in frequency rate occurred in six groups where data was

    recorded. In particular, the groups of Systemic locations (up 99.2 per cent from 0.05 in 2012–13

    to 0.10 LTI/Ds per million hours worked in 2016–17p), Head (up 32.4 per cent from 0.59 to 0.77),

    and Neck (up 18.3 per cent from 0.15 to 0.18).

    The Lower limbs group was associated with the majority of LTI/Ds in the reporting period. LTI/Ds

    decreased 16.5 per cent from a frequency rate of 2.83 in 2012–13 to 2.36 in 2016–17p). The

    Trunk group was the only other group to record a decrease in frequency rate in the reporting

    period (-9.4 per cent from 1.65 to 1.49).

    Age group

    The chart below represents the proportion of work-related LTI/Ds recorded by age group (where

    the age is known) for the total five year period in relation to the Education and Training industry

    division.

    Over a third of all LTI/Ds were recorded in the 45-54 year old age group over the five year period.

    LTI/Ds for this age group increased 7.7 per cent from 452 in 2012–13 to 487 LTI/Ds in

    2016–17p).

    Four further age groups recorded increases during the reporting period. These were the 25-34

    age group (up 18 per cent from 122 to 144 LTI/Ds), the 55-59 age group (up 18.9 per cent from

    201 to 239), 60-64 age group (up 18 per cent from 128 LTI/Ds to 151), and the 65-100 age group

    (up 41.2 per cent from 51to 72).

    Three age groups experienced a reduction in LTI/Ds during the reporting period: the 15-19 age

    group where LTI/Ds reduced by 83.3 per cent (from 42 LTI/Ds in 2012-13 to seven in 2016–17p),

    the 20-24 age group (-50 per cent from 62 to 31), and the 35-44 age group (-1.5 per cent from

    269 to 265).

    Explanatory notes A number of issues affect the data quality of statistical information based on claims data, as

    provided by the Department of Mines, Industry Regulation and Safety (DMIRS). It is important to

    be aware of these issues when interpreting claims statistics, to ensure that the conclusions

    drawn from the information take into account known inconsistencies and omissions.

    Injury and disease claim data

    The data used in this report is derived from workers’ compensation claims lodged in accordance

    with the Workers’ Compensation and Injury Management Act 1981 (the Act). Claims may be

    lodged by any person who is a ‘worker’, as defined by section 5 of the Act. This includes working

    directors who are deemed ‘workers’ under the Act and have some ownership of the company, as

    well as employed family members and private household workers (for whom workers’

    compensation cover is optional). Self-employed persons, Commonwealth Government workers

    (including defence service personnel), workers covered by Comcare, police officers (except for

    work-related fatalities), unpaid volunteers and students on work experience are excluded from

    workers’ compensation data.

    In addition, the following claim types are excluded from lost time claim data:

    journey claims between home and work;

    asbestos-related diseases, including mesothelioma and pneumoconiosis;

    duplicated or disallowed claims;

    claims with less than one working day absence from work;

    claims with less than one whole shift absence from work; and

    injuries and diseases that are treated in the health system (i.e. invalid pensions and

    sickness and unemployed benefits).

    Claim data represents information on claims by the financial year in which the claim was lodged

    with the insurer. This is in contrast to claim payments, which reflect actual payments during a

    financial year regardless of when the claim was lodged. A claim may typically take a number of

    months to be finalised (particularly in the case of occupational disease). As claims information is

    dynamic in nature, reports should be considered as a snapshot in time of the workers’

    compensation system in Western Australia. Data are subject to revision as claims information

    matures. A one year time lag exists in relation to workers’ compensation claim data.

    Due to the high percentage of un-finalised claims concerning payments and days lost, data is

    subject to revision and likely under reported. This is especially true in relation to the latest

    snapshot of preliminary data (denoted by “p”) as it is extracted at a far earlier stage resulting in a

    higher proportion of immature claims. Consequently, when looking at changes over time

    particularly in respect to LTI/Ds 60+ days/shifts lost (severe cases), time lost from work and claim

    costs, the reader is advised to focus on the older more stable years and treat the preliminary

    data year as an indication.

    Unless otherwise stated in this report, data refers to lost time injuries and diseases (LTI/Ds) in

    Western Australia where one or more days/shifts are lost from work. The latest snapshot of

    preliminary data is denoted by “p”. To ensure confidentiality of workers’ compensation claims

    information, incidences that total less than five are denoted by the data symbol '

  • Work-related lost time injuries and diseases in Western Australia 2012–13 to 2016–17p 17 Education and Training Industry Profile (ANZSIC 2006)

    Caution needs to be exercised when using workers’ compensation payments data as a measure

    of the cost of workplace injury and disease. The costs data collected are only those paid by the

    workers’ compensation authority and will not include payments made by the injured worker which

    are not reimbursed by the workers’ compensation authority.

    ‘Total estimated cost’ takes into account estimated and actual claim payments made for

    un-finalised claims and actual claim payments made for finalised claims in relation to

    compensation (such as weekly payments, lump sum payments, treatments etc.) and

    non-compensation payments (such as legal costs, transport etc.).

    Claim payment information represents aggregated expenses attributed to the financial year in

    which a payment is made, regardless of the year in which the relevant claim is lodged.

    The total number of days lost takes into account estimated and actual days lost for un-finalised

    claims and actual days lost for finalised. Estimates of days lost for un-finalised claims are revised

    as claims progress, therefore, as claims mature, the estimates are more reflective of the finalised

    days lost.

    Legislative amendments may also impact on statistical information. WorkCover WA provide

    information regarding relevant legislative amendments on their website, at

    www.workcover.wa.gov.au

    Frequency and incidence rates require knowledge of the number of employees and the number

    of hours worked for the time frame being considered. The employment data used to calculate

    frequency and incidence rates in department statistical publications is derived from unpublished

    data estimates produced by the Australian Bureau of Statistics (ABS).

    Classification systems

    The industry classification codes used are in accordance with the Australian and New Zealand

    Standard Industrial Classification (ANZSIC) published by the Australian Bureau of Statistics. The

    classification codes are based on a hierarchal structure consisting of one digit codes (broadest

    level) down to four digit codes (finest level). For more information visit www.abs.gov.au

    The occupation classifications used are in accordance with the Australian Standard Classification

    of Occupations 2nd Edition (ASCO), for data reported up to and including the year 2008–09, and

    the Australian and New Zealand Standard Classification of Occupations First Edition (ANZSCO),

    for data reported from the year 2009–10 onward. Both are published by the ABS. For more

    information visit www.abs.gov.au

    The injury and disease classification groupings and descriptions are the standard terms taken

    from the National Occupational Health & Safety Commission publication: Type of Occurrence

    Classification System (TOOCS). For more information visit www.safeworkaustralia.gov.au

    Due to the differences in structure and definitions between each version/edition of the three

    coding classifications a break in time series has occurred. To ensure data integrity direct

    comparisons should not be made between classification versions.

    Work-related traumatic injury fatalities

    Work-related traumatic injury fatality information used in this report is derived from information

    recorded and published by DMIRS and relates to fatalities that result from a physical trauma or

    poisoning in Western Australia in accordance with the Occupational Safety and Health Act 1984,

    Energy Safety Act 2006, Electricity Act 1945, Gas Standards Act 1972, Mines Safety and

    Inspection Act 1994, Petroleum (Submerged Lands) Act 1982, Petroleum and Geothermal

    Energy Resources Act 1967 and the Petroleum Pipelines Act 1969. In scope are employees,

    self-employed workers, volunteers and bystanders. Diseases and most disorders that would be

    seen as 'diseases', such as cancers and heart attacks, are out of scope. Other exclusions

    include: road traffic accidents, unless there is a clear nexus with work; self-inflicted injuries,

    Commonwealth Government workers, workers covered by Comcare and defence personnel.

    For completeness, DMIRS includes in its statistics those work-related fatalities covered by the

    Civil Aviation Act 1988 and Transport Safety Investigation Act 2003 under the respective

    jurisdictions of the Civil Aviation Safety Authority (CASA) and the Australian Transport Safety

    Bureau (ATSB); and where possible, those covered under the Australian Maritime Safety

    Authority Act 1990 under the jurisdiction of the Australian Maritime Safety Authority (AMSA). The

    former named agencies are common examples of valid jurisdictional boundaries however, the list

    is not exhaustive. For more information see Recording of traumatic work–related fatalities by

    WorkSafe.
