Drones Outshine Shark Nets in Detecting Threats, Queensland Study Finds

According to a report published in November 2025, the Queensland government has found that drone surveillance is significantly more effective than traditional shark nets in detecting potential threats. The study, which monitored 10 beaches over four years, revealed that drones spotted 676 shark sightings, including 190 for sharks larger than 2 meters, far exceeding the 284 sharks and 133 large sharks caught in adjacent Shark Control Program gear.

Drones have proven to be a valuable tool, providing lifeguards with a real-time aerial view of the ocean and enabling them to better manage safety risks without being overly cautious. When large sharks are spotted, people can be quickly evacuated from the water. Drones also offer additional benefits, such as assisting in search and rescue efforts and monitoring beach conditions.

In contrast, the shark nets had a much higher environmental impact, with 123 non-target animals, including 13 dolphins, 8 whales, 45 turtles, and 2 dugongs, caught during the trial period. About half of these animals were already dead when retrieved.

Despite the clear advantages of drone surveillance, the Queensland government has stated that it will continue to rely on "traditional measures like nets and drum lines" as part of its Shark Control Program. The use of drones, however, will be expanded from 10 to 20 beaches, becoming a permanent fixture in the state's shark management efforts.
