A 35-year-old surfer was fatally mauled by a shark on Saturday off a notorious stretch of Australia's west coast, police say.
The shark ''bounced off the board'' of one surfer ''before attacking the other male'' off a beach near Gracetown, said Western Australia state police Sergeant Norm Giocas.
The sleepy community of Gracetown has now been the site of three fatal shark attacks on surfers in the past decade. Surfers were also killed there in 2004 and 2010.
The victim, whose identity was known but not immediately released while police notified relatives, died instantly from massive injuries, Giocas said, adding that beachgoers brought his body ashore.
Surfer Ryan Scanlon saw the body and told the PerthNow news website that the victim had lost his left arm and flesh from his right leg.
The state Fisheries Department immediately closed beaches in the area, which is the state's premier surfing and wine-making region, located south of the state capital, Perth.
The victim lived in Margaret River, the main town in the region.
Marine officers were being sent with shark catching gear to deploy in the surrounding waters as soon as possible, the department said.
No details about the type of shark were immediately released, although great whites were often responsible for fatalities off the west coast.
The fatality was the first this year in Australian waters, where shark deaths average more than one a year and were becoming increasingly common.
After a spate of five fatalities off the west coast within 12 months scared tourists and locals alike, the Western Australia government last year approved a plan to kill sharks that ventured too close to people in the water.
The policy infuriated conservationists and marked a sharp reversal of the previous policy, which permitted the killing of sharks only after they attacked.
There have been several shark attacks in Australian waters recently that did not end in death.
Greg Pickering, a 55-year-old abalone diver, was attacked around the head and back last month by what officials suspect was a 3-metre great white shark near the Western Australia city of Esperance, southeast of Perth.
It was the second time Pickering had found himself in the jaws of a shark in nine years. In 2004, he was bitten on the leg while spearfishing near Cervantes, north of Perth.
