"Parks and Wildlife Service personnel are working in partnership with registered volunteers and other organizations to try to return the remaining 46 whales to deeper water during the course of the day," said the department.

The mass whale stranding incident triggered a shark alert issued by the state government of Western Australia, as the possible dead and injured animals may attract sharks to come closer to the shore

It also urged members of the public to stay away from the beach for safety concerns.

Cheynes Beach Caravan Park noted that an incident management team has been established by DBCA.

"Experienced staff from DBCA are currently being deployed, including Perth Zoo veterinarians and marine fauna experts, along with specialized equipment, including vessels and slings," the park updated on its social media.

On Tuesday morning, DBCA received reports that a large pod of long-finned pilot whales clustered about 150 meters off Cheynes Beach.
