Thursday’s attack came less than three months after a shark fatally attacked 57-year-old surfer Mercury Psillakis at Dee Why on Sydney’s northern beaches in September. His widow, Maria Psillakis, has called for an overhaul of alert systems at Sydney beaches.

Shark receivers, which ping when a tagged animal swims within 500 metres, are in place at 37 beaches along the NSW coast between Tweed Heads and Bega. There is no receiver at Kylies Beach, with the closest located at Old Bar, about 30 kilometres south.

Police on Thursday contacted the consulate general of Switzerland in Sydney and the couple’s family abroad. The Herald has made attempts to contact the couple’s family.
