The WA Government is for the first time in WA extending daily aerial patrols of both south-west and metropolitan beaches beyond April 2018.
Surf Life Saving Western Australia (SLSWA) has been provided around $350,000 in additional funding to continue daily aerial patrols in the south-west and metropolitan areas until May 27, 2018.
Patrols began on September 2, 2017, three weeks earlier than the year before, and were due to conclude on Monday, April 30, 2018.
Due to higher levels of marine animal activity, including sharks, daily patrols will continue to cover the same areas for an additional month. It will cost about $350,000 for the additional month of service.
There are a number of environmental factors in the marine environment that could potentially create higher levels of shark activity in localised areas along the WA coast over the late summer and autumn period, including mass whale strandings and the salmon run.
On March 23, 2018, 105 Long-finned Pilot Whales stranded themselves at Hamelin Bay – the largest stranding in almost 10 years. In the following weeks a further 25 whales washed ashore along the south-west coast.
The high number of injured whales or carcasses, on or close to shore, could be providing an opportunistic food source, or acting as an attractant for a range of large animals, including white sharks.
The annual salmon run is known to attract large marine animals during this period and a departmental media release reminder about this was issued in March 2018, as the first signs of the salmon run were being noted.
Water users are urged to check SharkSmart’s shark activity map or Surf Life Saving WA’s Twitter, before going into the water. Report any shark sightings to Water Police on 9442 8600.
