A man attacked by a shark off Western Australia’s coast on Saturday died of his injuries, police said, in what is the second fatal shark attack in Australia so far this year.

The 38-year-old victim, yet to be identified, was bitten on Saturday morning at Horseshoe Reef near Rottnest Island, about 31 kilometres (19.2 miles) west of 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.
