(CNN)A 36-year-old man died after being attacked by a shark off the coast of Fraser Island in the Australian state of Queensland on Saturday, local police said in a statement.
The man was spearfishing in the waters off Indian Head when he was bitten by a shark.
The man suffered injuries to his leg. A doctor and a nurse tried to save his life on the beach, but he passed away at about 4.30 p.m. local time.
Saturday's attack marked the fourth shark-related death in Australia this year. In April, Queensland wildlife ranger Zachary Robba, 23, was killed by a great white shark also near Indian Head.
In June a 60-year-old surfer died after being bitten by a great white shark in the state of New South Wales, while in January a 57-year-old diver died from a shark attack off Western Australia state.
