Bunker Bay, Cowaramup Bay and Lefthanders Surf Break's shark warning system will now be automated to alert beachgoers to the presence of a tagged shark.
The state government made the announcement on October 17 saying it had enhanced its shark mitigation measures in the lead up to summer.
As well as the beaches in the South West, Twilight beach and Kelp Beds in Esperance will also have the automation system.
An additional two automated towers have been allocated to the Town of Cottesloe for deployment.
The automation system will work when the shark monitoring network receiver detects a tagged shark and will trigger the beachside tower's flashing lights, siren and audio message and will operate for at least one hour after the detection.
Local Government rangers and Department of Primary Industries and Regional Development officers will continue to manually activate the towers when public shark sightings are reported.
The two shark warning towers at Surfers Point and Gas Bay in Margaret River will continue to operate manually.
Under the new automation program, the beachside Shark Warning System towers will operate between 5am to 7pm from the start of the October school holidays until the end of April, and then between 6am to 6pm for the remainder of the year.
Fisheries minister Don Punch said it was great to be able to make the safety announcement in time for summer.
"The Shark Warning System beachside towers provide direct valuable alerts of shark activity, but wherever and whenever you head for the ocean, remember to switch on your Sea Sense and check the SharkSmart App," he said
"The McGowan Government has committed $17 million to boost the services and infrastructure that support Western Australia's shark response and notification system.
"We have the most comprehensive and strongest evidence-based shark mitigation strategy in the world, so that people can continue to enjoy WA's beaches and ocean with confidence."
