The attack happened just after 1 p.m. on Sunday as the man was diving from a boat at Cull Island, located off the south coast town of Esperance.

The Department of Primary Industries confirmed the attack, saying, “a man received fatal injuries after being bitten by a reported (great) white shark.”

The body of the man, who has yet to be identified, has not been found.

“Esperance Police and Marine Rescue WA volunteers deployed to the area on board the marine rescue vessels,” a police spokesperson said. “They are still searching the ocean for the victim.”

Great white shark gives divers an up-close thrill.

A woman who was on board the boat at the time of the attack was treated at an area hospital for shock.

The incident on Sunday was the second fatal shark attack in the area in less than three years.

In April 2017, 17-year-old Laeticia Brouwer died after being attacked by a great white shark while surfing with her father off Esperance.

The area, famous for its white beaches and stunning blue water, is thought to be popular for abalone diving, according to Sky News.

The shark attack happened at Amitié Beach in Praslin, the second-largest island in the archipelago known for pristine beaches and secluded islands — where Prince William and Kate Middleton spent their 10-day honeymoon.

The victim, a 45-year-old woman, had ventured into the sea after dark when she was attacked.

French Ambassador Dominique Mas told the Seychelles News Agency the woman was severely injured on one arm and transported to the Seychelles Hospital.

“She underwent an operation last night and her vital prognosis is not in danger,” he told the news agency.

The attack took place during what is peak tourist season in the island chain and spurred a warning by authorities for tourists to avoid swimming in the area.

Shark attacks are described as extremely rare in Seychelles, though two tourists — one French and one British — were killed in shark attacks off Praslin in August 2011, according to Agence France-Presse.

Authorities said the incident happened in an area of cooler water near the island that could attract sharks during breeding.

In the wake of the attack, the Seychelles Maritime Safety Administration cordoned off the area and is investigating what type of shark was involved, according to the Seychelles News Agency.
