Cottesloe and North Cottesloe beaches closed after shark sighting while whale carcass sparks warning for Boranup Beach, near Margaret River
Cottesloe and North Cottesloe beaches are closed after a 2.5m shark was sighted 300 metres offshore.
The unknown species of shark was spotted by the Westpac Lifesaver helicopter at 3.15pm.
The closures come after a shark warning was issued for a South West beach after a decomposing whale carcass was reported nearby.
Surf Life Saving WA has warned a carcass off Boranup Beach, near Margaret River, could attract sharks close to shore.
The carcass was reported by a member of the public just after 1pm.
People are being told to take extra care in the area until it is removed.
Department of Biodiversity Conservation and Attractions officers are attempting to bring the carcass to shore.
Surf Lifesaving WA says heavy machinery will be prepared overnight before attempts to remove the carcass tomorrow.
Anyone who sees a shark is asked to report it to Water Police on 9442 8600.
