A snorkeler was bitten in the leg by a shark Monday, a day after two surfers were attacked by sharks in separate incidents across Australia.

Steven Fogarty, 24, said he was floating Monday in waters off Windang, in southern New South Wales state, when he felt something tugging on his right leg.

"I just saw the blood all over both feet and had a quick look to make sure both legs were there and they were there," Fogarty said.

He said he then punched what appeared to be a bull shark until it let go.

Fogarty flagged down a nearby boat and was taken to a hospital for treatment of about 50 puncture wounds to his calf and cuts on his fist. He was released from the hospital later Monday.

On Sunday, a teenage girl and a man were injured in separate shark attacks.

Hannah Mighall, 13, was twice dragged under water by a 16-foot white pointer shark while surfing in Tasmania state, Police Senior Sgt. Jason Elmer said.

Her adult cousin Syb Mundy punched the shark to make it release the girl before dragging her onto his surfboard and paddling to the beach, Elmer said.

Jono Beard, 31, paddled his board to shore after a shark bit his left thigh Sunday while he was surfing off a remote beach in New South Wales, lifeguard coordinator Stephen Leahy said.

The Daily Telegraph newspaper reported Monday that Beard lost a chunk of flesh up to 16 inches wide and 4 inches deep.

Although sharks are often spotted off Australia's beaches, fatal attacks are rare.

The last was on Dec. 27, when a 51-year-old man was killed while snorkeling off Australia's west coast. He was one of only two people killed by sharks in Australia last year.
