The type of shark involved in the latest attack has not yet been identified.

Emergency services responded promptly, treating the victim at the scene before transporting him to the hospital.

This incident adds to a troubling trend of shark attacks in South Australia, which has seen multiple fatal incidents in recent years.

Authorities have closed the beach at Port Noarlunga in response to the attack, reflecting growing concerns over shark activity in the region.

Following the attack, swimmers were evacuated from the popular snorkeling and diving site to ensure their safety.

On May 15, 2025, a man in his 40s sustained serious injuries from a shark bite while swimming off the Port Noarlunga jetty in South Australia, and he is currently in critical condition with severe wounds to his thigh.

The recent attack follows four fatal shark incidents in South Australia since 2023, including the deaths of 28-year-old Lance Appleby and 15-year-old Khai Cowley.

Earlier this year, Lance Appleby was killed by a great white shark while surfing at Granites Beach, and his body was never recovered.

Port Noarlunga Beach, located 33 kilometers south of Adelaide's CBD, is a well-frequented area for swimming and fishing.

Some experts link the increase in shark encounters to the protection status of great white sharks established in 1999, although this claim is disputed by others who argue the shark population has remained stable.

The timing of these incidents is particularly poignant as the World Surf League prepares for the Margaret River Pro in Western Australia, scheduled from May 17-27.

In addition to the fatalities, there have been non-fatal attacks, such as those involving Pam Cook and Bridgette O'Shannessy, who survived their encounters in late 2023.
