Shipwrecks of Magnetic Island

The Ghost Fleet of Magnetic Island

A Maritime Heritage Trail

Magnetic Island is more than just a tropical paradise; it is a graveyard of the Great Barrier Reef's maritime past. With over 20 known shipwrecks encircling its shores, the island offers a unique "underwater museum" where history meets nature.

 

From the haunting, mangrove-clad ribs of the City of Adelaide to the hidden wartime relics of the Moltke, these sites tell stories of survival, industry, and the raw power of the Coral Sea. Whether you are a walker, snorkeler, or history buff, this guide is your portal into the secrets lying just beneath the surface.

ICONIC "WALK-TO" WRECKS

Perfect for families and non-swimmers at low tide.

  • City of Adelaide (1916): Located in Cockle Bay. A 1863 passenger steamer turned "floating forest." It is the most photographed wreck in Australia for a reason.

  • George Rennie (1902): (Shown above). Located in Picnic Bay. A former paddle steamer whose iron skeleton provides a striking silhouette against the sunset at Hawkings Point.

  • Presto (1896): Located in Nelly Bay. An iron barque scuttled over a century ago to protect the island’s original timber jetty. Its bow now sits on the Nelly Bay Harbour entrance - on the "Presto Breakwater".

THE LEGACY OF CYCLONE SIGMA (1896) 

In January 1896, a devastating cyclone which caused immense destruction and reshaped the coastline, claiming several vessels in a single night.

  • Lavina: A timber brigantine which use to ferry timber and sugar, was lost at Rocky Bay.

  • Fate: Wrecked near Liver Point on the north west corner of Magnetic Island.

  • Burdekin: A sugar transport beached just offshore from the southern end of Young Bay.

  • Lalla Rookh: The ketch timber transporter which was torn from its moorings and can now be found in Alma Bay.

  • Presto: (As shown above - see "Walk-to Wrecks")

WINGS OVER THE WATER: WWII RELICS

Magnetic Island played a vital role in Northern Australia's defense.

  • Curtiss Falcon (1943): A US Army aircraft that ditched in Geoffrey Bay. While the pilot was heroically rescued, the propeller remains a silent underwater sentinel.

For more WWII relics, remember to visit the Forts while you're visiting. It's the No. 1 walk on Magnetic Island.

Safety and conservation

SAFETY FIRST

  • Check the Tides: Walk-to wrecks require a low tide.

  • Don't Climb: Rusted iron and barnacles are razor-sharp.

  • Stinger Suits: Essential from November to May.

  • Currents: Some offshore wrecks like the Octopus have strong tidal pulls.

CONSERVATION:

  • Look, Don't Touch: These are fragile historical sites and protected habitats.

  • Leave It There: Removing artifacts is illegal under the Underwater Cultural Heritage Act 2018.

  • Eco-Snorkeling: Avoid standing on the wrecks or surrounding coral.

  • Be Aware!: Ensure that all diving equipment is not dragging, be aware of your fins, and exercise buoyancy control.

  • No anchors: Don't tie marker buoys or access lines directly to the shipwrecks.

  • Observe from the outside: Please don't enter the wreck.
