A 38-year-old man died on Saturday after he was attacked by a 13-foot shark in Australia.

The attack happened at Horseshoe Reef near Rottnest Island on Australia’s western coast just before 10 a.m., police said. 

The island is located about 19 miles west of Perth.

The man was brought back to shore but never regained consciousness.

"A 38-year-old man was in the water at Horseshoe Reef when he was believed to have been bitten by a shark," a spokesperson for St. John WA Ambulance told 12-year-old died a week after he was attacked by a shark in Sydney Harbor.

Three others were attacked within the same two days along the New South Wales coast in non-fatal incidents.
