Shark nets are around 150 metres long and lie several hundred metres offshore in the water. Contrary to what many beachgoers believe, they do not form a barrier. Sharks can easily swim under or over the nets. Around 40 per cent of the trapped animals become entangled on the inshore side, meaning they had already reached the swimming area. Moreover, the nets do not only kill sharks but also dolphins, sea turtles, and other marine life—completely indiscriminately.
Alternatives to killing sharks
Australia has been using modern, non-lethal methods for several years, such as drone surveillance, SMART drumlines (where sharks are caught, tagged, and released), real-time alert systems, and public education. States like South Australia or Western Australia have already abolished shark nets and rely exclusively on these approaches.
In Queensland, by contrast, the use of nets and baited lines has even been expanded recently—a course of action criticised by experts as a politically motivated “tough stance” on sharks.
Changing societal attitudes
Studies show that while the public’s fear of sharks remains consistently high, support for lethal measures is declining. Many people were previously unaware that nets are designed to kill sharks, not to keep them away. Recent research also indicates no difference in shark encounters between beaches with or without nets.
Rare incidents – other dangers greater
Between 2015 and 2025, Australia averaged about 20 injuries and nearly three fatalities per year from shark attacks. In the same period, 150 people drowned while swimming last year alone, including 84 at beaches. Statistically, the risk from sharks is very low compared to other dangers at sea.
A first step with symbolic impact
The selection of beaches for the trial is the responsibility of local councils, which are to submit their proposals to the government by the end of August. Experts view the initiative as a significant turning point: it provides an opportunity to demonstrate the benefits of modern protection methods to the public while also enhancing the protection of endangered marine animals.
