It was just a Sunday.
March 3, 1985. The sun was out over Peake Bay in South Australia, and the water at Wiseman's Beach looked exactly like the kind of place you’d want to spend a family afternoon. Shirley Durdin, a 33-year-old mother of four, was out in the shallows. She wasn't miles offshore or doing anything reckless. She was just snorkeling for scallops.
Then the water changed.

Most people think of shark attacks as quick, splashy moments you see in movies. But the shirley durdin shark attack remains one of the most harrowing accounts in maritime history because of the sheer scale of the predator and the fact that it happened right in front of her husband and children. This wasn't just a "bite." It was a total predatory event that left a community, and the world, in absolute shock.
The Morning at Wiseman’s Beach
Wiseman’s Beach is tucked away about 15 miles north of Port Lincoln. If you know anything about South Australia, you know this is "Great White" territory. But back in the mid-80s, the local mindset was a bit different. People swam there all the time.
Shirley was about 150 yards from the shore. The water was only about 6 or 7 feet deep. Honestly, that’s the part that gets most people. You think you're safe if you can almost touch the bottom. Her husband, Barry Durdin, was watching from the beach. Her four kids—Jason, Tanya, Carla, and Sonya—were right there too.
Witnesses say the shark didn't circle. It didn't give a warning.
A massive Great White, estimated by onlookers and later by experts to be around 20 feet (6 meters) long, struck Shirley with incredible force. It hit her so hard she was basically lifted out of the water. In a single, gruesome moment, the shark bit her in two.
Barry and the kids had to watch this from the sand. Imagine that for a second. One minute your mom is waving from the water, and the next, a 2-ton fish is ending her life in front of your eyes.
A Rogue in the Bay?
The sheer size of the shark involved in the shirley durdin shark attack led to a massive hunt. Locals called it a "rogue." This is a controversial term in marine biology. Most experts today, like those from the Rodney Fox Shark Foundation, will tell you sharks don't usually "hunt" humans on purpose. They're curious, or they mistake us for seals.
But this specific shark was different.
When the rescuers and local fishermen scrambled into their boats, the shark didn't leave. It stayed in the area. When a boat approached the spot where Shirley had been, the shark actually came back and finished devouring her remains while the rescuers watched.
Nothing was left. Not a trace.
Why the Shirley Durdin Shark Attack Still Matters
You've probably heard of Jaws. That movie came out a decade before this happened, but the Durdin case felt like the movie had come to life in the worst way possible. It changed the way South Australians viewed the ocean.

Before 1985, there was a sort of "it won't happen to me" vibe. After this, things got tense. A few days after the attack, a shark net was put out to try and catch the animal. The next morning, the net was found torn to pieces. It was like the predator was sending a message, though we know now it was just a very large, very powerful animal doing what it does.
The hunt for the "rogue" shark went on for days. The Port Lincoln Game Fishing Club and local abalone divers were out in force. They used berley (bait) to try and lure it back. Peter Hurrell, a spokesman for the local diving club at the time, suggested the shark might have been old or injured. His theory was that it couldn't catch its normal, faster prey, like seals, so it went for something slower in the shallows.
Whether that’s true or not is still debated. Great Whites are apex predators; they don't really need an excuse to strike.
The Aftermath for the Family
The community in Port Lincoln rallied, obviously. About 500 people showed up for the memorial service at the Uniting Church. But the trauma for the Durdin family is something that doesn't just go away.
Barry Durdin later spoke about the "wall of water" and the "dark shape" that just appeared. It happened so fast. There was no time to swim out to her. No time to scream a warning that would have made a difference.
- Location: Wiseman's Beach, Peake Bay, SA.

- The Predator: A Great White shark, approx. 6 meters.
- Outcome: Fatal; body never recovered.
Lessons from a Tragedy
We know way more about shark behavior now than we did in 1985. If you're heading into the water in Great White territory, there are things you just don't do.
First off, stay away from "drop-offs" or areas where people are cleaning fish. In the case of the shirley durdin shark attack, she was snorkeling for scallops. Some believe the act of disturbing the seabed or the scent of the scallops might have attracted the shark, though that's never been proven.
Also, the time of year matters. March in South Australia is a transition period for water temps. These sharks are moving.
Honestly, the best thing you can do is be aware. Use a shark shield if you're a serious diver. Don't swim at dusk or dawn. And if you're in an area known for sightings—like Peake Bay—maybe keep the snorkeling to a minimum if there's been recent activity.
The story of Shirley Durdin isn't just a "scary shark story." It’s a reminder that the ocean is a wild space. We are guests there.
If you're interested in the history of these encounters, look into the work of Rodney Fox. He survived a massive attack himself and turned his life toward protecting the very animals that nearly killed him. It gives a lot of perspective on how we can coexist with these predators without the "rogue" hunting mentality of the 80s.
Keep your eyes on the horizon and respect the depth.
Next Steps for Ocean Safety
To stay safe in Great White territory, always check local shark sighting apps like SharkSmart before heading out. If you are diving or snorkeling in high-risk areas, consider investing in an independently tested electronic shark deterrent. Most importantly, never swim alone in isolated bays where help is far away.
