Friends of the man killed in a shark attack on Sydney’s Northern Beaches last Saturday have returned to the scene a week on, to conquer their fears.

He had been out for a morning surf with several of his mates, who had tried to save him.

A week after his September 6 death, his friends were back in the water to honour the 57-year-old.

Psillakis’ sister was among those visiting today, while friend Toby Martin admitted to feeling scared to return.

“But I think we’ve got to lean into the fear,” he told 9News.

“To confront what’s been presented to us in a place we go everyday. That’s what he would have wanted. That’s what we want for our community.” 

A memorial has been set up on the beach, offering a place for healing for the community.

Local receivers today pinged for sharks around Avalon and Palm Beach.

The state had initially planned to remove shark nets in three locations in the Northern Beaches, including Dee Why, as well as areas within Waverley and Central Coast councils this summer to test their effectiveness in a trial.

Premier Chris Minns had indicated he would delay the trial until the Department of Primary Industries released its report on the shark incident. However, just days after, Agriculture Minister Tara Moriarty announced that the trial would be canceled before the report was completed.

Shark nets were reinstalled at 51 beaches from Newcastle to Wollongong on September 1.

Dee Why beaches have 150-metre-long, six-metre-deep shark nets installed about 500 metres from the shore.

Authorities have installed additional drumlines between Long Reef and Dee Why.
