A man has been killed in a shark attack off South Australia's Yorke Peninsula.
Police say the 28-year-old Adelaide man was part of a spear-fishing group when he went missing in the water off Goldsmith Beach, near Edithburgh, about noon on Saturday.
Witnesses have told police they saw the shark attack the man and raised the alarm after they were unable to find him.
Locals say there have been reports of a great white shark in the area in the past week.
The ABC reports the attack comes as the Western Australian Government fends off criticism of a shark culling programme it introduced last month to protect swimmers.
The policy allows for great white, tiger, and bull sharks larger than three metres to be killed, while smaller sharks are to be released.
Opponents of the policy say there is no scientific evidence that killing the sharks will reduce their threat to swimmers.
