The results of shark mitigation trials
Session 1
NSW SHARK MANAGEMENT STRATEGY AIM
Increase protection for beachgoers from shark interactions
while minimising harm to sharks and other marine animals.
Surveillance, Detection and
Deterrents

Education and Community Awareness
NSW SHARK MESHING PROGRAM‘Shark nets’
• Longest running shark mitigation program since 1937• The NSW Government’s Shark Meshing (Bather Protection) Program includes
51 beaches between Newcastle and Wollongong.• Set 1 September – 30 April each year
SURVEILLANCE, DETECTION AND DETERRENTSMost preferred technologies

DRONES
Tests and Trials included:
• Comparison with helicopters & spotter• Development of operating procedures• Integration with beach safety• Artificial intelligence, beyond line of
sight, automation
DRONES
Benefits
• No impacts to marine animals• Cheap and easy to operate• Potential for automation• Suitable for events• Rapid response and general
beach surveillance
Considerations
• Flights are restricted within 1 kmof the pilot
• Proximity to airspace limits flightsand level of pilot training
• Limited by sea conditionseg. water turbidity and wave chop
• Trained pilots needed

Benefits
• Information on movement and distribution of sharks
• Alerts in real time• The public can download the
SharkSmart App to mobile devices and set it to receive notifications for certain locations, times and alert types
LISTENING STATIONS
Considerations
• Only detects tagged sharks• Requires a tagging program to tag
sharks to detect
HELICOPTERSConsiderations
• Very expensive• Surveillance short time
while flying overhead• Relies on good conditions
(e.g. water turbidity/ sea surface chop)
• Requires trained observers
Benefits
• No impacts to marine animals
• Surveillance at unpatrolled beaches
• Cover large areas of coastline
• Work with beach authorities to herd shark out to sea

TECHNOLOGIES TRIALLED AND CURRENTLY NOT SUITABLE FOR NSW
The science of sharks
Session 2
SCIENCE AND RESEARCH
White Sharks
• travel great distances• are not permanent residents
of any one location• many move north in winter
and south in summer
Bull Sharks
• can live in rivers, estuaries and nearshore areas
• large sharks travel north for winter and return to NSW for summer and autumn
• juveniles reside in the estuary in which they were born for up to 5 years
SCIENCE AND RESEARCH
Tiger Sharks
• prefer warm seas and live in both nearshore and offshore waters
• travel great distances• many travel north for
winter and south for summer
