Controversy Surrounds Calls for Shark Culling Following Sydney Beach Attack
In the wake of a recent shark attack at a Sydney beach, former Australian Prime Minister Tony Abbott has called for the culling of sharks, a statement that has sparked significant debate among marine experts. The attack, which occurred on Saturday morning, left a woman in her 30s critically injured after being bitten on the leg and arm by what is believed to be a great white shark.
Abbott made his remarks via a social media video, asserting that it is “so wrong that we don’t cull sharks after attacks.” He further advocated for the establishment of a fishery designated to capture sharks. However, experts in marine biology have pushed back against Abbott’s perspective, emphasizing that such measures would not effectively reduce the risk of future shark encounters.
Emeritus Professor Rob Harcourt, who leads the Marine Predator Research Group at Macquarie University, stated, “Tony Abbott doesn’t understand risk, he does not understand climate change, and he doesn’t understand the science when he calls for a cull.” Harcourt elaborated that unless white sharks are completely removed from the ocean—a highly impractical and ecologically detrimental approach—a cull would not lower the risk of attacks.
Harcourt characterized the recent incident as tragic yet rare, suggesting that calls for a cull stem from a reactionary mindset rather than evidence-based reasoning. Similarly, Professor Culum Brown, a fish behavior researcher at Macquarie University, criticized the notion of shark culling as a naive political ploy and emphasized the need for coexistence with marine wildlife rather than an “18th-century approach to annihilating nature.”
The New South Wales Premier Chris Minns has sided with the experts, noting that great white sharks are a protected species. He expressed skepticism about the effectiveness of a cull, stating, “I’m not convinced it would work, and we’ve certainly had no expert evidence suggesting that we could ward off great whites from our beaches as a result of a cull.” Minns highlighted the migratory nature of sharks, suggesting they could originate from various distant locations, complicating any localized culling efforts.
In light of these debates, Minns advocated for a reevaluation of shark protection strategies in the state, focusing on innovative solutions such as shark netting and enhanced surveillance, including the use of drones. Harcourt also endorsed the use of drones for beach monitoring, arguing that their deployment could significantly reduce the likelihood of shark bites by guiding surfers and swimmers to safety when sharks are detected.
On Monday, the Civil Aviation Safety Authority temporarily lifted a ban on using drones for shark surveillance at Coogee Beach, a location close to Sydney Airport flight paths. Dr. Daryl McPhee from Bond University has indicated that had drones been operational during the recent incident, the bite might have been preventable. He noted that incidents at patrolled beaches are exceedingly rare due to vigilant monitoring.
Statistical trends reveal a noticeable increase in shark bites in New South Wales, rising from an average of 0.6 incidents per year from 1980 to 1999 to 4.16 in recent years. Dr. McPhee attributes this increase to population growth, which leads to more individuals entering the water, and an increase in whale populations that may attract more great white sharks along the coast.
Marine biologist Lawrence Chlebeck of Humane Society International reiterated that culling is ineffective due to the migratory behavior of sharks, emphasizing that such actions might inadvertently heighten shark activity. He stated that since 2012, the state’s shark nets have killed 174 great white sharks, along with numerous other species, further complicating conservation efforts.
As discussions continue, experts advocate for a shift in focus toward coexistence and innovative solutions to enhance beach safety without resorting to culling, which they argue poses both ecological risks and questionable effectiveness.
