Two-time world champion snowboarder Alex Pullin has died while spearfishing in his native Australia, local officials have confirmed.
Pullin, 32, was found unresponsive off a beach on Queensland's Gold Coast on Wednesday.
He was treated by paramedics at the scene but could not be revived, authorities said.
Nicknamed "Chumpy", Pullin was Australia's flagbearer at the 2014 Winter Olympics in Sochi.
A Queensland Ambulance spokesman said: "The man was spearfishing off Palm Beach. He was brought to shore by bystanders where he was treated by local lifesavers and paramedics."
A snorkeler had spotted Pullin unconscious underwater on an artificial reef, local media said.
Lifeguards brought him to shore and called paramedics about 10:30 local time (00:30 GMT).
A police official told Australia's Channel 9 News that Pullin appeared to have been diving alone.
"He didn't have an oxygen mask, we understand he was free diving and spearfishing out on the reef," Officer Chris Tritton said.
The athlete had previously shared pictures online of himself spearfishing, swimming and surfing.
The sport's Australian top body, Snow Australia, said it was "shocked and saddened" by Pullin's death.
"Alex was a beloved member of the Snow Australia community and he will be dearly missed," it said in a statement.
"An incredible athlete, beloved teammate and role model, you will be sorely missed," the Australian Olympic Team, which Pullin had been part of three times, said.
