A father-of-two who was killed by a great white shark off Gracetown in WA has been described as an "absolute champion" by those who knew him in his hometown in Queensland.
Chris Boyd, 35, was killed instantly on Saturday morning at the popular surf break "Umbies", about 270km south of Perth.
Friends from the Coolum Boardriders' Club in Mr Boyd'e hometown have paid tribute to the man who has been described as a "legend and an inspiration to many".
The shark that Mr Boyd in the waters off Western Australia bounced off the board of another surfer before fatally attacking him, police say.
Eyewitnesses described how a nearby surfer dragged the injured man onto his board and ferried him to shore.
Those who witnessed the aftermath described how the victim was missing his left arm and part of his right leg.
Beach-goers looked on in horror as the man could not be revived. His yellow and green surfboard was recovered.
The state's fisheries department issued a catch and kill order for the shark, saying there was an imminent threat of more attacks in the area.
Acting Sergeant Norm Giocas of Margaret River police said the shark had initially struck out at one surfer in the water, before fatally wounding another.
"From what we understand, the shark bounced off the surfboard of one surfer before attacking the other," Acting Sgt Giocas said.
Police spoke to the man's tearful friends and relatives when they arrived at the beach as word of the tragedy spread.
His body was taken from the area by helicopter.
Moments after the catch and kill order, Surf Life Saving WA reported a large shark had been spotted offshore of Ellensbrook homestead near Gracetown.
The beaches near Lefthanders surf break have been closed, as has an eight-kilometre stretch of beach from Umbies to South Point and on to Huzzas, North Point and the main Gracetown beach.
The beach closures will be in place for 24 hours.
Gracetown is the site of three fatal shark attacks in the past 10 years.
Surfer Bradley Smith was taken by a great white at a beach near the town in 2004, and another surfer, Nicholas Edwards, was killed by a shark at nearby South Point in 2010.
Saturday's attack comes weeks after abalone diver Greg Pickering was bitten on the face and body by a five-metre great white while diving off the coast of Esperance.
It also comes as some of the world's finest chefs - including Heston Blumenthal - gather in WA's southwest for a gourmet tourism extravaganza.
AAP understands Blumenthal was surfing in waters near the site of the attack on Friday.
Many school leavers are also holidaying in the area.
