A woman is fighting for life after being mauled by a three to four metre shark at one of Australia's busiest beaches, with footage released of the animal believed responsible.
The incident follows a recent spate of fatal attacks nationwide and has prompted calls for stronger shark mitigation strategies.
Emergency services were called to Coogee Beach in Sydney's eastern suburbs shortly after 11am on Saturday following reports a swimmer had been bitten by a shark.
Bystanders pulled her from the water and started first aid before emergency services arrived.
Television presenter Fran Kelly was swimming nearby when she heard people screaming for her to get out before seeing others run into the water to rescue the victim.
"I saw them pulling her out and I could see the shark bite, which was big and awful," she told ABC News.
