There have been no fatal attacks in NSW on a netted beach since 1951, though there have been encounters with sharks. Shark fatalities across the whole state total two a year on average, across nearly 900 beaches.
Macquarie University Professor Culum Brown, a fish and shark scientist, said there was no statistical difference.

“There’s no scientific evidence … that suggests that you’re any safer swimming at a beach that has a net, versus swimming at a beach that doesn’t have a net,” Brown said. “That’s because deaths by sharks, and even shark bites, are so rare that it’s hard to model.”
The shark nets are just 150 metres long with gaps above and below them, so sharks can swim around, over and under them. Brown said a large percentage of the sharks caught in the nets were found on the beach side.
This masthead has previously reported on University of Sydney research that suggests that flailing sea creatures caught in the nets could actually attract sharks, making them counterproductive. Brown said this research was credible and many of the pictures showed that the dead animals had chunks bitten out of them.
Humane World for Animals, a charity that has been campaigning against shark nets, obtained documents under freedom of information laws that show that the government’s own Fisheries Scientific Committee advised the minister before last summer that the netting program should be discontinued. It said there were no differences between netted and non-netted beaches in attacks, while the nets were a “key threatening process” for endangered species such as grey nurse sharks.
In 2024-25, 223 animals were caught in the nets, the FOI documents show, and more than two out of three were killed. Only 24 animals caught were target species – four bull sharks, two tiger sharks and 18 great white sharks. Four dolphins were killed, 13 turtles were caught of which seven died, and 11 grey nurse sharks were caught of which four were killed.
In 2023-24, 29 turtles were caught in the nets. Last year, the shark nets were removed a month earlier because of increased turtle activity in April; inspections of the nets were increased during March; more drone surveillance was used to scout for turtles and there was also a trial of lights to deter turtles on 21 nets in February and March.
Moriarty said all 51 nets would include turtle lights this year.
Humane World for Animals marine biologist Lawrence Chlebeck said it was disappointing the nets were being installed on Monday because it would kill wildlife without making the beaches safer, but he was relieved the trial was going ahead.
Shekhina Maher, 32, grew up on the northern beaches and now lives in Bronte, where she swims in the ocean nearly every day, even in winter when there are no nets. She sees whales and dolphins but never sharks.

“It’s the shark’s domain – it’s their kingdom,” Maher said. “It’s so important to have the cycle of all the animals in the ocean with the apex predators and things like that. I’m all about balance.”
She said if the nets made people safer, it was “worth the conversation,” but she was concerned about the damage to marine life.
