When it comes to protecting swimmers from sharks, not all solutions are created equally. In Australia, the discussion around shark mitigation has grown and evolved considerably over the past decade, with increased awareness of the environmental impact of traditional methods. Two approaches that are often discussed, which include shark nets and shark barriers, are frequently confused. However, these two measures serve fundamentally different purposes. It is very important for local coastal councils, marine conservation organisations, and everyday beachgoers who care about both safety and environmental sustainability to understand the key differences between these methods.
Shark nets have been used in New South Wales since the 1930s and are installed seasonally at 51 beaches between Newcastle and Wollongong. These nets are part of the Shark Meshing (Bather Protection) Program, which aims to decrease the chances of shark encounters by capturing and killing specific species such as white sharks, tiger sharks, and bull sharks. However, the nets do not form a complete enclosure and are not made to prevent sharks from entering swimming areas. In fact, many sharks caught in the nets are often seen swimming away from the shore, having already moved past the area where people swim. According to the NSW SharkSmart website, the nets are intended to intercept sharks, rather than serve as a physical barrier between swimmers and marine animals. These measures are designed to protect beachgoers, but they are not entirely reliable and cannot completely eliminate the risk of shark encounters.
The issue with shark nets is that they are completely indiscriminate in what they catch. They trap anything that swims into them, whether it is a shark, dolphin, turtle, ray, or even a seal. According to data obtained by Humane Society International and reported by 9News, nearly 90 per cent of animals caught in New South Wales shark nets are species that are not the intended target. This includes endangered marine creatures such as leatherback turtles and grey nurse sharks. The high number of by-catch incidents has led to a renewed call for the permanent removal of shark nets. Many experts and conservationists believe that this practice is outdated and causes unnecessary harm to marine life.
In March 2025, the New South Wales Government announced that the shark netting program would end a month earlier than usual in order to better safeguard migrating turtles. This decision was welcomed by many marine conservation advocates who have long been advocating for more humane and environmentally friendly approaches. However, the future of the program remains uncertain as discussions continue over the most effective methods to protect swimmers and marine life. According to reports from the Australian Broadcasting Corporation, researchers and community leaders are increasingly encouraging the government to consider adopting more modern, non-lethal alternatives such as the use of drones for monitoring, listening stations to detect marine animals, and SMART drumlines, which are designed to be selective and safer for wildlife.
This is where shark barriers come into play. Unlike traditional shark nets, barriers are designed to create a clearly defined and demarcated swimming area that physically separates people from potentially dangerous marine creatures. They are not intended to catch or kill sharks. Rather, they serve as a protective enclosure, allowing swimmers to enjoy the ocean with peace of mind. Safer Swimming Australia’s enclosures exemplify this approach. They are constructed from semi-rigid mesh material and are securely anchored to the ocean floor. These barriers are capable of moving with the tide and swell, maintaining their structural integrity even in rougher sea conditions. They are built to meet Australian standards for breaking strength and are designed to have minimal environmental impact.
One of the most compelling features of SSA enclosures is our track record of having zero by-catch. Unlike shark nets, which many Australians have described as curtains of death, SSA barriers do not entangle marine life. They are carefully engineered to allow smaller marine creatures to pass through while keeping larger animals out. This distinction is not simply a technical feature; it is a significant ethical consideration. It demonstrates a strong commitment to coexistence rather than conflict and to protection rather than causing harm.
The difference between shark nets and shark barriers is not merely a matter of their physical design. It runs much deeper, touching on the fundamental philosophy behind their use. Shark nets operate on the belief that ensuring human safety involves making sacrifices; they accept that protecting people often results in the unintended death of marine life. Conversely, shark barriers challenge this way of thinking. They provide a solution that is both effective and humane, treating the ocean as a shared environment that must be respected rather than a battleground where conflict is inevitable.
As public sentiment in Australia continues to evolve and local councils reassess their shark mitigation strategies, it is crucial that decisions are based on facts rather than fear. The Guardian reports that there is increasing support within communities across the country for the removal of shark nets, with many residents calling for investment in smarter and more sustainable technologies. Safer Swimming Australia enclosures serve as an excellent example of this kind of innovative solution. They are designed not only to protect swimmers but also to help conserve the marine environment for future generations.
In the end, the choice between shark nets and shark barriers is a choice between old habits and new ways of thinking. It is a choice between reactive measures and proactive design that aims to prevent problems before they occur. Most importantly, it is a choice between causing harm and promoting harmony with the marine environment. At Safer Swimming Australia, we strongly believe that safety should never come at the expense of marine life. Our enclosures demonstrate clearly that it is possible to ensure safety in the water while also respecting and protecting marine creatures.
Whether you’re a local council along the coast seeking sustainable solutions or a community advocate who is deeply passionate about protecting our oceans, now is an ideal time to consider the benefits of shark barriers that focus on both safety and ecological responsibility. Safer Swimming Australia is ready and willing to partner with organisations and communities across the entire country to establish safer swimming zones that do not compromise our valuable marine biodiversity. Get in touch with us today to find out how our zero by-catch enclosures can assist in transforming your beach into a leading example of coexistence between humans and marine life. After all, ensuring the safety of people and the preservation of marine ecosystems should always be a shared priority.
