A man is missing and believed to have died after being bitten by a shark on the west coast of the Eyre Peninsula in South Australia.
South Australia Police have confirmed that a 46-year old man was surfing when he was attacked by a shark, and is now missing.
Paramedics were called to a beach near Elliston shortly after 10am on Saturday to assist a man following reports there had been a shark attack.
The incident was reportedly witnessed by multiple surfers at Walkers Rock Beach, which is near Elliston.
South Australia Police were leading the search for the man on Saturday, with local community members assisting, while the SA State Emergency Services sent a sea rescue boat from Port Lincoln.
