Shark detections occur when an acoustically-tagged shark swims within approximately 400-500 metres of a receiver.
Sharks are fitted with acoustic tags which emit a sequence of low frequency ‘clicks’ that give each tag an audible ID number.
The Surf Life Saving WA (SLSWA) Twitter feed at twitter.com/slswa is the best way to keep up-to-date with any detection of tagged sharks, by the State Government’s Shark Monitoring Network, as well as any sightings reported by members of the community to Water Police.
