You're standing on the golden sands of Bondi or maybe the rocky cliffs of Little Bay, looking out at that deep Pacific blue. It’s stunning. Honestly, it’s why most people move to this city. But then that tiny, nagging thought creeps in. You’ve seen the headlines. You’ve heard the stories of Sydney Australia shark attacks that stop the city in its tracks.
Is it actually safe to go in?
Most of us grew up with Jaws on a loop, which basically ruined our ability to look at a dark patch of seaweed without a mini heart attack. But the reality in Sydney is way more nuanced than "don't go in the water." It’s a mix of changing climates, better technology, and some really tragic cases of being in the wrong place at the wrong time.
The Elephant (or Shark) in the Room: Recent History
For nearly 60 years, Sydney felt almost immune to fatal encounters. That changed in February 2022. Simon Nellist, a 35-year-old diving instructor and regular at Little Bay, was killed by a great white shark estimated to be over three meters long. It was a "vertical attack," according to witnesses like Kris Linto—basically an ambush from below.
It was horrific.
Then, more recently, in September 2025, 57-year-old Mercury Psillakis was fatally attacked at Long Reef Beach. He actually spotted the shark first and warned his mates to get out. His family said he "saved his friends in the surf," but he didn't make it back himself. Biologists later identified the predator as a white shark around 3.5 meters.
When things like this happen, the city feels different. You see fewer people at the dawn sessions. People talk about "the big one" at the local pub. But if you look at the raw numbers from the Australian Shark-Incident Database, there have only been 312 fatal attacks across the entire country since 1791. In a city of five million people where almost everyone swims, those odds are actually incredibly low. Kinda puts it in perspective, right?

Why the Water Feels Different Lately
You might’ve noticed people saying there are "more sharks" now. Experts like Dr. Vincent Raoult from Macquarie University suggest it’s not necessarily that there are more sharks, but that we are seeing them more often.
Why? Drones.
We’ve got a massive fleet of drones now. The NSW Government’s Shark Management Program for 2025/26 has drones patrolling 50 beaches. When you have a camera in the sky every day, you’re going to spot things that have probably been there for centuries.
The "Diabolical Combination"
There’s a term used by Dr. Chris Pepin-Neff: a "diabolical combination" of factors.
- Warmer Water: Climate change is heating up the East Australian Current.
- Lingering Bull Sharks: A study led by Nicolas Lubitz found that bull sharks are staying in Sydney for about 15 days longer than they did 15 years ago. They used to head north to Queensland the second it got a bit nippy, but now they’re hanging out until the water drops below 19°C.
- More People: We have more people in the water, for longer, wearing better wetsuits that keep us warm through winter.
Basically, the "window" of time where humans and sharks overlap is getting wider.
The Great Net Debate
Walk along any Sydney beach and you’ll likely see the yellow buoys marking the shark nets. They’ve been around since the 1930s. Most people think they act like a fence, keeping sharks out of the swimming area.

They don't.
They are basically just 150-meter-long strips of mesh that sit in the middle of the water. Sharks can swim under, over, or around them. In fact, many sharks are caught on the inside of the nets. The real controversy is what else they catch. Turtles, dolphins, and rays get tangled and die.
That’s why the government is pivoting. They’re moving toward SMART drumlines. These are anchored buoys with a baited hook. When a shark takes the bait, it triggers a GPS alert. A team arrives within 30 minutes, tags the shark, and moves it about a kilometer offshore. Data shows these relocated sharks usually stay away for months. It’s a lot more "human-quality" than just letting a net kill everything that swims into it.
Common Myths vs. Cold Hard Facts
We’ve all heard the "rules." Don’t swim at dusk. Don’t swim after rain. Let's look at what actually matters.
- The Dawn/Dusk Rule: This one is actually legit. Bull sharks—which are the real "locals" of Sydney Harbour—are more active when the light is low. They use the gloom to hunt.
- The Seal Lookalike: People often say surfers look like seals. While white sharks do hunt seals, some experts think it’s more about curiosity or "investigatory bites." Unfortunately, a "test bite" from a three-meter shark is catastrophic for a human.
- The Harbor is Safe: Most people think the harbor is safer than the ocean. Actually, Sydney Harbour is a massive nursery for bull sharks. They love the murky, brackish water, especially after a heavy downpour when the runoff brings in nutrients (and baitfish).
How to Actually Stay Safe
If you're going to swim in Sydney, you don't need to live in fear. You just need to be smart about it.
First, download the SharkSmart app. It’s connected to 37 "listening stations" along the coast. If a tagged shark swims within 500 meters of a station, your phone pings. It’s surprisingly effective. If you see a notification for a 4-meter Great White at the beach you’re standing on, maybe just go grab a coffee instead.

Second, avoid the "bait." If you see birds diving or schools of small fish jumping, get out. Sharks aren't looking for you, but if you're in the middle of their lunch, accidents happen.
Third, stay near the shore. Most incidents occur when swimmers or surfers are further out, isolated from the crowd. Sharks are ambush predators; they like an easy, solitary target.
Actionable Steps for Your Next Surf or Swim
Instead of worrying, take control of the variables you can.
- Check the App: Open SharkSmart before you leave the house. Look for recent sightings or tagged detections at your specific beach.
- Avoid Murky Water: If there’s been a big storm, stay out of the water for a few days. The runoff makes it impossible for sharks to distinguish between a fish and a human foot.
- Swim at Patrolled Beaches: Lifeguards aren't just there for drownings. They have a direct line to drone pilots and fisheries. If they blow the whistle and hold up a red flag, move fast.
- Ditch the Bling: Leave the shiny jewelry at home. To a shark, a flashing silver watch looks exactly like the scales of a struggling fish.
- Stick to Enclosures: If you’re really nervous, Sydney has some of the best netted harbor pools in the world—places like Murray Rose Pool or Greenwich Baths. They have actual physical barriers.
Sydney is a coastal city. The ocean is their backyard, but it's also a wild ecosystem. We share it with predators that have been there for millions of years. Respecting that fact—rather than fearing a "monster"—is the only way to enjoy the water safely. Stay alert, stay informed, and maybe don't go for a solo splash at 8:00 PM in the middle of a rainstorm.
Practical Safety Resources
- NSW SharkSmart Mobile App: Available on iOS and Android for real-time alerts.
- BeachSafe App: Provides current conditions and patrol status for every Sydney beach.
- DPI NSW Website: Check the latest "Shark Management Program" maps to see where SMART drumlines and listening stations are currently active.
The reality of Sydney Australia shark attacks is that they are rare, but they are a part of life in a city that lives by the sea. By using the tech we have and following basic ocean safety, you can keep the risk as low as possible.
