Dive the S.S. Yongala shipwreck, Great Barrier Reef — and you’re not just exploring a sunken ship. If you’re chasing the kind of dive that makes your hair stand on end (even underwater), then diving the SS Yongala Wreck is about as legendary as it gets. Tucked beneath the warm waters of the Great Barrier Reef Marine Park, just off Cape Bowling Green, this ghostly relic delivers an eerie mix of maritime mystery, epic marine life, and a full-blown underwater ecosystem that’s teeming with colour, life, and stories.
And it’s not just a pretty site. This wreck’s got teeth — strong currents, depth, and a whole heap of “respect the ocean” energy. Chuck in a few sea snakes, a snoozing Marble Ray, and the occasional Giant Trevally the size of your leg, and you’ve got yourself a dive that lives up to every inch of the hype.
Why This Dive Site's Hot Topic
There are loads of dive sites on the East Coast of Australia, especially around the Outer Reef, but the Yongala Wreck? She’s in a league of her own.
What makes it one of the most revered dive spots in the world?
- Artificial reef turned marine metropolis – coral polyps and soft coral have transformed the steel skeleton into a blooming reef ecosystem
- Incredible diversity of life – from coral species to apex predators
- Historical depth – both literally and metaphorically
- Strict protection – courtesy of the Barrier Reef Marine Park Authority
It’s not just a wreck; it’s a living, breathing reef community — a haven for marine species big and small.
Tucked Beneath the Waves
The Yongala rests on the sandy bottom 30 metres below the surface in the Coral Sea, part of the Great Barrier Reef Marine Park, about:
- 12 nautical miles east of Cape Bowling Green
- 70 km south-east of Townsville
- 48 km offshore from Ayr (near Alva Beach)
It’s in a remote patch of open water with no other reef structures nearby, which makes it a magnet for marine life.
Most divers launch from:
- Alva Beach (near Ayr) – shortest boat ride (~30 mins)
- Townsville – longer trip, but more dive operators and infrastructure
Unravelling the Eerie Legend
Let’s wind the clock back to 1911.
The S.S. Yongala was a passenger steamship, chugging down the Queensland coast on its way from Mackay to Townsville. She was hauling freight, passengers, and a whole lot of ambition — including tonnes of coal, racehorses, and mail. But on 23 March 1911, she sailed unknowingly into a Category 5 cyclone.
No distress signals. No survivors. Just silence.
The wreck wasn’t found until 1958. And since then, it’s become a place of solemn intrigue and one of the most famous tourist destinations for divers in the Southern Hemisphere.
Some reckon it’s haunted. Others say it’s just the isolation that gets to you. Either way, descending onto the SS Yongala Wreck feels like entering sacred ground.
What You’ll See
Imagine the whole cast of a marine documentary showing up for one scene — that’s the Yongala Dive.
Expect to see:
- Giant Trevally, batfish, and big-eye trevally circling like sentinels
- Reef sharks, bull sharks, and if you’re lucky (or unlucky), the odd tiger shark
- Turtles lounging like they own the place
- Explosions of coral gardens and colourful coral
- Olive sea snakes weaving in and out like slippery ghosts
- Dense clouds of baitfish make everything shimmer
- Colonies of coral polyps blanketing the structure
It’s one of the most concentrated showcases of marine life on any single dive in Tropical North Queensland, thanks to its position as an artificial reef in otherwise empty seabed.

Safety and Environmental Considerations
The Yongala Wreck is situated within a protected zone of the Great Barrier Reef Marine Park and is overseen by the Barrier Reef Marine Park Authority and the Department of the Environment and Energy.
Safety Basics:
- Strong current? Listen to your dive guide. Seriously.
- Don’t enter the wreck — it’s illegal and structurally risky
- Stay aware — marine life here can be both massive and moody
Environmental Respect:
- Don’t touch coral communities — your GoPro shot’s not worth it
- Avoid disturbing the plant species and the bottom silt
- Report any damage or poor visibility (possibly due to a decline in water quality) to park rangers or your operator
Efforts like the Handbook for the Great Barrier Reef and Flora of the Great Barrier Reef World Heritage Area emphasise diver responsibility in preserving the diversity of life on sites like the Yongala.
Real yarn from the deep
I’ll never forget my second dive at the Yongala. The swell was rocking the boat like a pub stool after a big Friday. We rolled off the side, followed the mooring line, and there she was.
Schools of Giant Trevally moved like shadows. A Marble Ray glided past, unfazed by our bubbles. A sea snake did a drive-by. I hovered above the wreck and felt this mix of awe and sadness, knowing what had happened here. It was like the ocean had both claimed and honoured this ship.
