A shark warning has been issued for waters off Yallingup in WA's south West after a surfer was knocked off his board by a shark at Injidup Beach.
The surfer was assisted to the shore and did not suffer any injury.
Unconfirmed reports say the surfer may have been launched into the air during the attack however, a well-timed wave helped all the surfers in the water reach the shore unscathed.
The species of the shark is unknown, though Surf Lifesaving WA tweeted the shark may have been a Great White.

It's the same stretch of coastline where 25-year-old Matthias Bache went missing after cliff diving in March.
Further down south, another shark was spotted just 50 metres from shore at Kelp Beds Beach near Esperance.
There's been over 60 shark sightings off WA's coast in recent weeks with the Department of Fisheries even closing a stretch of coastline in Perth's northern suburbs over what it called "an unprecedented number of sightings over a sustained period of time and in a small stretch of water."
The Department of Parks and Wildlife has erected signs at Injidup Beach warning of recent shark activity and water users are being urged to take extra precautions in the Yallingup area.
