A second surfer has been attacked by a shark in Gracetown just hours after a man was airlifted to Perth for emergency surgery.
The man has been flown to Royal Perth Hospital by helicopter and is in a stable condition.
A man in his 30s, who was surfing at Cobblestones Beach near Gracetown, was bitten on the leg but managed to body surf to shore where bystanders used a rope from his surfboard to apply a torniquet.

A spokeswoman said he was being assessed and would later be transferred to the trauma unit.
St John Ambulance Western Australia said the injured surfer, aged in his 30s, was "conscious and breathing and being treated for leg injuries".
Surf photographer Peter Jovic saw the attack from the beach and said there were only about five people in the water at the time. "There was a lot more thrashing around".
Another radio caller said other surfers had been spooked by the shark and had started leaving the water just before the attack happened.
"It is possible the decomposing carcass will continue to act as an attractant that could lead to sharks coming close in to shore along this stretch of coast", a statement said. [I] saw the guy who had been attacked get separated from the [surf] board and then start to paddle for an inside wave, which he managed to body surf all the way in.

Another witness, Brett Newland, told the station it was a "large shark" and that "from the way it was behaving, it would have been a white pointer" - better known as a great white.
The Margaret River Pro is being held nearby and had been taking place in Gracetown over the weekend.

"We have been alerted of a shark incident that occurred near Gracetown", organisers said on Monday.
"The #MargiesPro is on hold while we work with local authorities".
"The safety of our surfers & staff is a top priority". Organizers added more drones and jet skis to ensure the safety of competitors. Chris Boyd, 35, was killed at nearby Umbies surf break in 2013.
Surf Life Saving WA had noted several sightings of sharks in the area, including a four-metre shark off Lefthanders, near where the attack happened, this morning.
