An aerial search will resume on the New South Wales south coast tomorrow for a shark that attacked a 24-year-old man.

Steven Fogarty was snorkelling at Windang near the entrance to Lake Illawarra when the shark bit him on the leg, leaving 40 puncture wounds.

He described the shark as a bull shark and said he punched the shark until it let go.

Mr Fogarty was released from hospital this afternoon.

Aerial Patrol spokesman Harry Mitchell says a search of the lake and nearby beaches found no sharks, despite recent sightings.

"We launched the aircraft over the top of the area, within 10 minutes of the alleged attack, and we carried out a surveillance east of the bridge through the channel there and in other parts of the lake as well, with no evidence of any shark activity," he said.

It is the third shark attack off Australian beaches and the second in New South Wales in the past two days.

A 31-year-old Brisbane man was surfing with three friends when a shark bit him on the leg at Fingal Beach on the north coast of NSW yesterday.

Thirteen-year-old Hannah Mighall was attacked by a five-metre white pointer shark at Bailey's Rocks yesterday afternoon.

Beach warning

The spate of shark attacks across Australia so far this summer has prompted New South Wales far south coast lifesavers to warn swimmers to be vigilant.

Far south coast director of lifesaving Mark McLeay says there have only been a few sightings in the region this summer, but people need to be alert.

"One thing I want everyone to realise is that if you do see something that could be a shark, raise the alarm," he said.

"It is a lot better to be prepared than to get attacked."
