The man, from Queensland, was killed while surfing on Salt Beach near Kingscliff on the northern coast of New South Wales, according to Surf Life Saving New South Wales.
Shortly after. 10 a.m. Sunday, police and emergency responders were notified that a man had been attacked on the beach. Several other surfers and boarders had already rushed to rescue him as they fought the shark and then helped the man to shore, local police say in a statement.
He was bitten on the back of the thigh and received first aid onshore for serious injuries to his left leg, but died at the scene, Surf Life Saving said in a statement.
Beaches between the towns of Kingscliff and Cabarita close in 24 hours.
The first responders, police and biologists are now monitoring the area.
Surf Life Saving deployed several jet skis, drones and helicopters to track the shark. Authorities discovered it from the air and took photographs.
Shark biologists assessed these photos and the man’s bite marks and determined it had been a large, large white shark measuring approximately three feet (9.8 feet) according to Surf Life Saving.
The attack is the latest in a handful of other fatal shark encounters in Australia this year. In January, a diver was apparently attacked by a large white shark off the southern coast of Western Australia, although his body was not recovered. In April, a parker and an animal leader killed a shark near the Great Barrier Reef.
