The 38-year-old victim, yet to be ​identified, was bitten on Saturday morning ​at Horseshoe Reef near Rottnest Island, about ⁠31 km (19.2 miles) west of the state capital Perth, ​police said in a statement.

The man was taken ​to shore but could not be revived, police said, adding that a report would be prepared for the ​coroner.

State authorities advised people to take extra ​caution in the water at Rottnest Island, a popular ‌tourist ⁠destination.

Aerial footage from the Australian Broadcasting Corporation showed a police boat, police officers, and a rescue helicopter with a stretcher at the scene.

The ​attack follows ​the death ⁠in January of a boy bitten by a shark in Sydney Harbour, ​after a series of shark attacks ​along ⁠the country’s east coast.

Most shark attacks occur along the east and southeast seaboard of Australia, which ⁠averages ​around 20 such incidents a ​year, according to Australia’s Institute of Health and Welfare.
