The 32-year-old, believed to have been in Australia on a working holiday, was diving alone about 500m off Little Armstrong Bay on the island’s north-west coast when the predator struck about 1.30pm, Perth Now has reported.
Police said two people aboard a private 25-ft Bertram boat made a desperate emergency call after seeing bubbles in the water, before the man’s body surfaced a short time later with “obvious traumatic fatal injuries.”
Passengers travelling back to Perth from Rottnest Island today spoke of their shock and disbelief over the latest fatal shark attack in WA waters.
Police spokesman Gerry Cassidy said witnesses on the boat told police they had seen the shark, which they described as a 3m white pointer.
It is not clear if the man had been diving from a charter vessel or part of a dive tour operating in the area when the fatal attack happened.
It comes just 12 days after respected Perth businessman Bryn Martin disappeared while swimming at Cottesloe Beach. He is presumed dead, the victim of a shark attack.
