The 57-year-old man, named as Mercury Psillakis, was surfing with friends just after 9:30am on Saturday when the attack occurred. Police said he had been in the water for around half an hour and was only about 100 metres from shore when he disappeared beneath the surface. Fellow surfers managed to bring him back to land, but he had suffered catastrophic injuries and could not be revived. His surfboard was later found broken in two.
Authorities closed Dee Why Beach, the closest patrolled location, where restrictions will remain in place for up to 72 hours. Beaches between Manly and Narrabeen have also been temporarily shut. Drones have been deployed along the coastline, and five SMART drumlines are now set between Dee Why and Long Reef to detect shark movements. A shark net is already in place at Dee Why.
The Department of Primary Industries is examining photographs and damaged equipment to identify the species of shark involved. Police divers also assisted in recovering evidence from the scene.
“Officers attached to Northern Beaches Police Area Command have closed the beach and will liaise with experts from the Department of Primary Industries to determine the species of shark involved,” the NSW Police Force announced.
“Two sections of a surfboard have been recovered and taken for expert examination.”
“Beaches between Manly to Narrabeen have been closed pending further advice.”
Psillakis, an experienced surfer and father, leaves behind a wife and young daughter. The Northern Beaches community has expressed its grief, with tributes flowing for a man described as well-known in local surf circles. Council and Surf Life Saving officials thanked first responders and members of the public who tried to help.
