š¦ Whatās Actually Happening With Sharks Right Now, And Why We Need Science, Not Panic.š¦
Thereās been a lot of fear circulating after the recent shark encounters, and much of it is based on the idea that sharks are suddenly behaving differently, coming closer to shore, becoming more aggressive, or āhunting humans.ā None of this is supported by science. There is no increase in shark aggression, no unusual movement patterns, and no evidence that sharks are targeting people. What we are seeing is a normal winter pattern that has been documented for decades.
Great White sharks naturally move closer to the NSW coastline in winter because the water cools, the whale migration passes through, and the fish who they actually eat. including mullet and salmon, travel northward in tight schools along the shore. Sharks follow fishes, not humans. This seasonal movement is wellāestablished in research from CSIRO, NSW DPIās SharkSmart program, Bond University, and longāterm tagging studies. It happens every year, whether humans notice it or not.
At the same time, Bull Sharks leave Sydney in winter. They prefer warmer water and tend to move north or offshore when the cold sets in. So the idea that āall sharks are suddenly coming closerā simply doesnāt match the biology. Different species move differently, and their patterns are predictable.
Many people have been unsettled by the fact that the Coogee incident happened on a clear winter day between the flags. But that isnāt mysterious either. Winter brings clear water, and clear water is ideal for White Sharks because they are visual predators. The gutters and sandbanks between the flags often hold the fish they feed on, and predators follow those fish. The only unusual element was that a human happened to be in the water at a time of year when fewer people swim. Winter encounters feel rare because fewer swimmers are present, not because sharks behave differently.
Sharks are not a threat to the ocean, they are essential to it. As apex predators, they regulate entire marine ecosystems. Without sharks, fish populations destabilise, seagrass beds decline, coral reefs suffer, and the oceanās ability to store carbon drops. A healthy ocean requires sharks. Losing them would be far more dangerous to humans than encountering them.
What has changed is not shark behaviour, but the way we talk about it. More drones, more GoPros, more beach surveillance, more media coverage, and more social media amplification all create the impression that shark encounters are increasing, even when longāterm data from Tarongaās Australian Shark Incident Database shows no upward trend. When fear spreads quickly, it creates pressure for governments to consider drastic measures like culls or expanded nets, even though decades of research show these approaches do not reduce risk. This is how moral panics form: a rare event becomes a catalyst for fearādriven policy instead of evidenceābased management.
Sharks are not changing. The ocean is not changing. Whatās changing is the narrative, and the louder the fear becomes, the more pressure there is for harmful, ineffective responses. If we want safer oceans and healthier ecosystems, we need evidenceābased understanding, not fearābased policy.
