Description:
Bradley Adrian Smith, 29, died on Saturday afternoon after being "bitten in half."
Witnesses said the surfer tried to beat off the sharks, which officials said were probably great whites, although they said they could have been bronze whaler sharks.
"We saw the guy start scrambling around and saw him clinging to the shark and... trying to whack it and trying to get away," surfer Mitch Campbell said.
An ambulance officer said the victim suffered extensive injuries to the pelvis and abdomen. He died on the beach near the small fishing village of Gracetown before medical workers reached him.
A witness, who was not named, said that two teenagers who pulled the victim out of the water claimed one of the sharks was "as big as a car."
