A shark killed a 50-year-old swimmer Tuesday at eastern Australia's popular Byron Bay.
With an extraordinary act of bravery, beachgoer Mark Hickey swam 15 to 20 meters (50-65 feet) into the water at Clarkes Beach to retrieve the severely wounded victim, who was identified by police on Wednesday as British-born Paul Wilcox, 50, received medical treatment on the beach but did not survive.
Ten reported that the shark had bitten through Wilcox's wetsuit on his upper right thigh, tearing off much of his leg. The wounds were being examined to identify the size and species of the shark.
The crew of a rescue helicopter spotted what appeared to be a great white shark later but lost sight of it.
The last fatal shark attack in Australia was April 3, when a 63-year-old woman was taken by a 3-to-4-meter (10-to-13-foot) shark near the village of Tathra, 340 kilometers (210 miles) south of Sydney.
Although sharks are common off Australia's coasts, the country has averaged fewer than two fatal attacks per year in recent decades. But fatal attacks are becoming more common. Two men were killed off the east and west coasts in one week last November. They were the only fatalities in 2013.
