Shark Attack Reignites Debate Over Effectiveness of NSW Shark Nets
Sydney, Australia – A tragic shark attack on saturday at Long Reef Beach in northern Sydney has once again brought the efficacy of shark nets into sharp focus.The victim, identified as Mercury Psillakis, was surfing near Dee why Beach, where a shark net had recently been installed as part of a wider rollout across 50 beaches from Newcastle to Wollongong. despite the presence of these nets, experts caution that they are not foolproof barriers against shark encounters.
The attack underscores a long-standing debate: do shark nets provide a meaningful level of protection for ocean users,or are they a costly and ecologically damaging measure offering a false sense of security?
What Do Shark Nets Actually Do?
Shark nets,typically 150 meters in length,are designed as gill nets anchored to the seabed and positioned to intercept sharks approaching popular swimming areas. However, as christopher Pepin-neff, a shark net researcher at Sydney University, explains, they are far from impenetrable.
“They’re these gill nets that are set in front of the swimming area in front of the flags, and they’re stable there. They’re sort of anchored there,” Pepin-Neff said. Crucially, the nets do not create a complete barrier. Large swells, strong currents, and marine debris can easily displace or compromise the netting, allowing sharks – and other marine life – to pass through.

This inherent limitation stems from the very nature of the ocean environment. As Pepin-Neff points out, “Mother Nature…we build things in the ocean – and mother Nature…” frequently enough finds a way around human intervention.
