Local authorities have confirmed that a surfer was injured late Friday following a shark attack off the coast of Gracetown in the WA's South West.
It's believed the man was surfing at South Point at around 6pm when he was bitten by an unconfirmed species of shark, suspected to be either a wobbegong or a small whaler.
He has since been released from hospital.
A shark alert has now been issued for the Gracetown area, with beachgoers told to take additional care.
Warning signs have been put up by the Shire of Augusta Margaret River, while fisheries officers from the Department of Primary Industries and Regional Development will continue to monitor the situation.
If you see a shark, report it to water police on 9442 8600.
