Imagine four shark encounters in just two days—a chilling reality that recently unfolded on Australia's east coast. This alarming cluster of incidents has sparked fear, debate, and a flurry of questions about what’s really going on beneath the waves. But here’s where it gets controversial: Are sharks the problem, or are we missing something much bigger?
On January 18, a 12-year-old boy suffered critical injuries after a shark attack while swimming in Sydney Harbour. Less than 24 hours later, an 11-year-old’s surfboard was bitten at Dee Why beach, followed by another attack on a man at nearby Manly, who was rushed to the hospital in critical condition. If that wasn’t enough, a fourth surfer was bitten just two days later, nearly 300 kilometers up the coast. This unprecedented string of events has left experts and locals alike scrambling for answers.
‘This is the closest series of shark bites—both in time and location—I’ve seen in my 20-year career,’ says Chris Pepin-Neff, a shark researcher and associate professor of public policy at the University of Sydney. The incidents prompted the closure of dozens of beaches and reignited calls for shark culls. But experts are urging caution, arguing that the real issue isn’t the sharks themselves—it’s the conditions that brought them closer to shore.
And this is the part most people miss: The recent attacks coincided with days of heavy rainfall, with Sydney recording its wettest January day in 38 years. This deluge created ‘perfect conditions’ for bull sharks, which thrive in warm, brackish water—a stark contrast to most other shark species. ‘Bull sharks love river mouths and estuaries,’ explains Rebecca Olive, a senior research fellow at RMIT University. ‘The freshwater runoff from the rain was like an open invitation for them.’
But that’s not all. The freshwater also carried sewage and nutrients into the ocean, attracting bait fish—and, in turn, sharks. ‘It’s like a biodiversity explosion,’ Pepin-Neff notes. ‘The bait fish come to the surface, the bull sharks follow, and suddenly, everyone’s in the same near-shore area.’
Are shark attacks on the rise? Official statistics show a gradual increase in shark bites over the past 30 years, from around 8-10 annually in the 1990s to mid-20s in recent years. But before you panic, consider this: The rise is likely due to better data collection, a growing coastal population, and more people engaging in water sports. ‘The number of encounters is higher because more people are in the water,’ Pepin-Neff clarifies. Yet, the rate of attacks hasn’t skyrocketed proportionally.
Here’s the kicker: Despite the media frenzy, shark attacks remain relatively rare. ‘Given how many people use the ocean daily, incidents are uncommon, and fatalities even rarer,’ Olive points out. The perception of increased danger may stem from better reporting, drone footage, and sensationalized media coverage. Plus, the term ‘shark attack’ often lumps together sightings, encounters, and bites, distorting our understanding of the risk.
Do shark culls actually work? In the wake of the Sydney attacks, calls for culls have grown louder. But experts are pushing back. ‘Culling sharks creates an illusion of safety,’ Olive argues. ‘It doesn’t make anyone safer.’ Pepin-Neff agrees, citing research that shows culls are ineffective. ‘The real issue isn’t the sharks—it’s the attractants drawing them in,’ he explains. ‘Even if you remove all sharks from an area, new ones will come if the conditions are right.’
So, how can we stay safe? Both experts emphasize awareness and pragmatism. Avoid swimming or surfing after heavy rain, and consider designated shark enclosures for safer ocean access. But the bigger shift needs to come in our mindset. ‘We need to treat the ocean like the wild it is,’ Pepin-Neff says. ‘Sharks aren’t the villains—we’re just in their way, not on their menu.’
Here’s a thought-provoking question for you: Should we focus on controlling shark populations, or should we prioritize understanding and adapting to their behavior? Let us know your thoughts in the comments—this debate is far from over.
