Rescuers were scouring the waters off a remote beach in South Australia on Saturday for traces of a surfer believed to have been killed in a shark attack.
Emergency services were called to the beach near the town of Elliston, about 650 km (403 miles) south of the state capital of Adelaide, following reports of the attack.
"A man is believed to have died following a shark attack at Walkers Rocks Beach," police said in a statement, adding that the 46-year-old was the only person thought to have been attacked.
