In late April and early May 2026, authorities in New South Wales (NSW) officially announced the end of the annual “shark net season,” removing nets from many of the state’s most popular beaches.
At first glance, this may seem like a risky move at the height of beachgoing season. In reality, the decision is driven by one of nature’s most remarkable events.
Each year, tens of thousands of humpback whales migrate north along Australia’s east coast. To ensure their safe passage, shark nets must be taken out of the water.
This seasonal action, however, raises a broader and increasingly urgent question: do shark nets actually make beaches safer – or do they simply create the illusion of safety?
Whales on the Move: A Journey Full of Risks
Every year, more than 40,000 humpback whales (Megaptera novaeangliae) travel from the cold Southern Ocean to warmer northern waters to breed. Their migration along Australia’s coastline is one of the largest marine movements on Earth.
Yet along this route, they encounter a hidden danger. Shark nets are not solid barriers; they are loosely suspended mesh structures designed to reduce shark presence near beaches. In practice, they function more like entangling traps.
Young whales are particularly vulnerable. Lacking experience, they can easily become caught in the nets, often with fatal consequences.
Past incidents, including whale deaths along the NSW coast, have intensified pressure from conservation groups such as World Wide Fund for Nature and Humane Society International to remove nets earlier in the migration season.
The Big Debate: Do Shark Nets Work?
The use of shark nets in Australia has long been controversial, dividing public opinion between tradition and science.
Arguments in Favor
Supporters point out that the program has existed since the 1930s and is associated with a decline in fatal shark incidents. For many beachgoers, the presence of nets provides reassurance – a sense that the ocean is being managed and controlled.
Arguments Against
Scientific evidence, however, challenges the effectiveness of shark nets. According to data from the New South Wales Department of Primary Industries, approximately 40% of sharks caught in nets are found on the shoreward side. This means they had already entered the swimming area.
Even more concerning is the issue of bycatch. Between 80% and 90% of animals caught in the nets are not target shark species. These include dolphins, sea turtles, rays, and endangered species such as the grey nurse shark (Carcharias taurus).
Additionally, dead or dying animals trapped in the nets may attract larger predators, including great white sharks – potentially increasing, rather than decreasing, risk near shore.
Technology as an Alternative: A Net-Free Future
Advances in technology are offering new, less harmful approaches to beach safety. SMART drumlines (Shark-Management-Alert-in-Real-Time) use baited hooks equipped with sensors that alert responders immediately when a shark is caught. Teams can then quickly tag and release the animal further offshore, often within 30 minutes.
Drone surveillance is becoming increasingly widespread. Lifeguards can monitor coastal waters in real time, spotting sharks more efficiently than traditional methods without harming marine life.
Acoustic monitoring systems, connected to the SharkSmart app, track tagged sharks via underwater receivers. When a tagged shark is detected, alerts are automatically sent to authorities and the public.
Regional Differences
While New South Wales is gradually reducing its reliance on shark nets, Queensland continues to operate a year-round shark control program.
These differences reflect not only policy choices but also shifting public attitudes. In NSW, growing numbers of residents oppose the nets, particularly after repeated cases of dead dolphins and whales washing ashore.
A recent incident near Wollongong in May 2026 further highlighted the issue. The recovery of a whale carcass led to temporary beach closures due to increased great white shark activity.
The event underscored a fundamental reality: nature cannot be fully controlled, regardless of human intervention.
Balance Between Human Safety and Environmental Responsibility
The seasonal removal of shark nets is more than a procedural decision – it represents a delicate balance between human safety and environmental responsibility.
Increasingly, evidence suggests that traditional shark nets are both ineffective and ecologically harmful.
At the same time, emerging technologies offer a new model – one based on monitoring, rapid response, and coexistence rather than entrapment.
The ocean remains a wild and unpredictable environment. The challenge is not to dominate it, but to learn how to safely exist within it.
