Tragedy struck the Northern Beaches community in early September when 57-year-old Mercury Psillakis was fatally attacked by a shark at Long Reef Beach.
Earlier this year, the NSW Government announced a trial to remove shark nets from three beaches across Sydney and the Central Coast, with local councils asked to nominate sites. Scientists and marine experts welcomed the move, arguing that nets provide a false sense of security and fail to prevent shark encounters.
Despite Long Reef Beach being netted, the day after Mr Psillakis’ death, NSW Premier Chris Minns delayed the shark net trial, calling it “the right thing to do” after such a devastating event.
The incident reignited debate. Advocates for removal argue the death shows nets provide little protection, while others see them as a necessary safeguard. Shark nets can reduce risks but also pose significant threats to marine life, killing not only sharks but dolphins, turtles, and other species.
Marine biologist Lawrence Chlebeck from Humane World of Australia said the nets are not barriers, noting sharks can swim over or under them.
“About 40% of sharks caught are found inside the nets, meaning they had already reached the beach,” he said.
As an alternative, experts highlight SMART drumlines, which use satellite technology to alert authorities when a shark is caught. This system enables rapid tagging, relocation, and release, offering improved beach safety while maximising survival rates for marine life.
It has been backed by experts as an efficient way to both keep animals and beach goers safe.
The debate now centres on whether nets protect swimmers or ultimately cause more harm than good.
