Shark management

In 2015 the NSW Government announced the NSW Shark Management Strategy, a program designed to complement the existing Shark Meshing Bather Protection Program.

The key objective of the NSW Shark Management Strategy is to increase protection for bathers from shark interactions while minimising harm to sharks or other animals.

This is a scientifically driven, integrated strategy involving several innovative approaches to provide the most effective shark attack mitigation measures at NSW beaches. The NSW Shark Management Strategy is an investment of more than $16 million to introduce innovative trials and fund continual projects over five years.

In September 2015, shark experts from across the world met at the NSW Shark Summit and considered an independent review of potential shark deterrent technology (PDF, 4142.53 KB) to be trialled in NSW waters.

  • Ongoing aerial surveillance providing more patrols along the NSW coastline.
  • Two state-of-the-art eco-friendly shark barriers to be trialled at Lighthouse Beach in Ballina and Lennox Head Beach. These trials were unsuccessful and were discontinued in August and September 2016.
  • 20 Satellite linked (VR4G) shark listening stations, to provide real-time tracking data of tagged sharks. Ten of these listening stations are deployed in northern NSW waters, including at: Kingscliff, Byron Bay, Lennox Head, Ballina, Evans Head, Yamba, Coffs Harbour, South West Rocks, Port Macquarie and Forster. Another 11 will be deployed at Lighthouse Beach, Ballina, Crescent Head, Old Bar, Bondi, Hawks Nest, Redhead, Kiama, Sussex Inlet, Mollymook, Batemans Bay and Merimbula.
  • Partnership with Surf Life Saving NSW and professional lifeguard associations to refine procedures for shark observation and incident response.
  • In-water surveillance trials of sonar technology. 'Clever Buoy'™ uses new sonar technology coupled with tailored software to detect shark sized objects. The manufacturer has completed initial sea trials at Bondi Beach. Further collaborative trials to determine the ability of this technology to detect potentially dangerous sharks will be conducted with the manufacturer and DPI.
  • Trials of unmanned aerial vehicles (UAVs or drones). These trials commenced in December 2015 and are continuing at Ballina, Lennox Head,. Evans Head, Redhead and Kiama until the end of 2016.
  • Monitoring of emerging promising technology, including the development of electronic shark deterrents will continue to determine their effectiveness and suitability.
  • Additional expert staff to roll out the NSW Shark Management Strategy.
  • Annual competitive grants, which will be advertised and funded to foster further commercial innovation in technologies for detection and deterrents.
  • Expansion of DPI shark tagging to tag more sharks and improve detection and reporting capabilities. This will include more tagging operations off the NSW coast by expert shark researchers over the next five years.
  • Trials of SMART Drumlines along the NSW coast.
  • Funding for advanced university research projects relevant to bather protection, including shark detection or deterrence.
  • More community awareness events to better educate the public about sharks and how to minimise their risk of a shark incident.
  • The popular SharkSmart Mobile App has been updated, to include real-time tracking of tagged sharks on a mobile phone/tablet and provide alerts when a shark is spotted.
  • Follow @NSWSharkSmart on Twitter to keep up to date with shark alerts
  • In response to an increase in the number of shark incidences in 2015/16 on the NSW north coast, the NSW Government's Shark Management Strategy includes a targeted north coast response.
  • The north coast was earmarked as a priority trial site for the deployment of two barriers, at Lighthouse Beach, Ballina and at Seven Mile Beach, Lennox Head. Due to the inability of the contractors to install both of these barriers successfully, the trials were discontinued in August and September 2016.
  • VR4G shark listening stations have been deployed on the north coast. An additional VR4G will be deployed at Lighthouse Beach, Ballina. Shark tagging will continue off the NSW north coast, as will targeted aerial surveillance.
  • A range of SharkSmart material specifically designed for the north coast  including posters, brochures and radio community service announcements have been distributed across the region.

Technology to be trialled

Trials of eco friendly shark barriers at Lighthouse Beach, Ballina and Lennox Head beach were discontinued after both manufacturers were unable to safely and effectively install the barriers.

Lighthouse Beach, Ballina

All barrier construction materials have been recovered from Lighthouse Beach and the beach has been restored to its original condition.

Lennox Head

Works have commenced to remove all barrier construction materials. Scheduled works will be undertaken over 2-3 weeks, weather dependant. Machinery will be on-site during this process. The beach will be restored to its original condition.

DPI has invested in satellite linked (VR4G) shark listening stations. These are receivers that record the presence of tagged animals swimming within a 500 metre radius of the listening station and provide real-time updates of tagged sharks close to key swimming/surfing locations.

Captured information goes straight to a satellite and is then instantly sent to the public and beach authorities via Twitter and the SharkSmart App. This data from the full network of listening stations also provides important insights into the movements of sharks in our waters.

DPI also manages several hundred VR2W listening stations that must be retrieved from the seabed to download data. This retrospective shark movement data provides finer scale information on shark movements and habitat use that will assist in understanding factors affecting shark distribution and their interactions with humans.

Sonar technology is a rapidly advancing surveillance technology that is potentially able to detect swimming objects underwater and relay information to shore. ‘Clever Buoy’™ has recently completed a trial of the technology at Bondi Beach to determine if this new sonar technology, coupled with tailored software, can detect shark-sized objects. Further trials will be completed in late 2016.

Unmanned aerial vehicles, often known as drones, offer emerging surveillance technology that provides aerial surveillance of coastal waters and real-time vision of the area.

DPI is currently trialling the use of UAV's and tethered aerial surveillance platforms in several locations, including the NSW north coast, as a form of shark spotting.

A review on UAV's for Marine Surveys was conducted in February 2015 by the University of Sydney.

Phase 3 of the drone trials is currently underway at Ballina, Lennox Head, Evans Head, Redhead and Kiama. The drones  will fly a 3.5-4km circuit over the ocean at a height of 60 metres and speed of 40km per hour, with an on-board camera providing real-time vision of coastal waters. CASA-certified pilots  fly the drones from vantage points for one hour in the morning every Thursday, Friday and Sunday until mid-December.

SMART (Shark Management Alert in Real Time) drumlines differ greatly from traditional drumlines as they are not designed to kill sharks. The state‐of‐the‐art technology alerts a response team when a shark is captured. The team then respond immediately to tag and potentially relocate the shark.

Initial testing of the SMART drumline technology occurred in the Bellinger River, south of Coffs Harbour, in late 2015 with scientists from Reunion Island. Further trials have taken place at several locations along the NSW coast and will continue in order for scientists to determine the best use of this technology.

These drumlines are only deployed when a team is on hand for immediate response.

15 SMART drumlines are currently in use along the NSW coast. An additional 85 SMART drumlines have been ordered and will begin to be rolled out before the end of the year.
