Surfers and swimmers are being warned to take caution around Preston Beach in Falcon, after a dead dolphin has washed ashore - potentially attracting sharks to the area.
Department of Biodiversity, Conservation and Attractions (DBCA) said the carcass was located about 1.5 kilometres off the northern entrance at the beach.
The spokesman said the decomposing carcass will potentially attract sharks to the Mandurah beaches.
“While it’s not uncommon for sharks to be present off the West Australian coast throughout the year, people should exercise additional caution until the dolphin carcass is removed,” he said.
DBCA officers are monitoring the situation and providing advice to relevant authorities.
If you see a shark, report it to Water Police on 9442 8600.
