The ex-HMAS Tobruk, a 127-metre Landing Ship Heavy scuttled in 2018, rests on its starboard side in 12–28 metres of water off the southern Great Barrier Reef. One of the world's newest wreck dives, it sits within the Great Sandy Marine Park near Fraser Island. The wreck's open design allows exploration of eight deck levels, including a 100-metre swim-through inside the cavernous tank deck. Rapid coral colonisation has already transformed the steel hull into a thriving artificial reef, attracting grouper, wobbegong sharks, rays, octopus, turtles, and vast schools of silversides. Sheltered by Fraser Island, the site typically offers excellent visibility year-round.

Moderate risk: Deep water depth
Depths of 10–28m mean this is a deep-water wreck site requiring proper buoyancy control and dive certification.
Moderate risk: Overhead environment / wreck penetration
The wreck is a confined, enclosed structure with overhead environments; penetration beyond the open deck areas requires wreck-diver training.
Low risk: Open ocean currents
Located 31 km offshore, the site is exposed to open ocean conditions and occasional strong currents.
Low risk: Tidal flows
Strong tidal flows can occur in the waters between the mainland and Fraser Island, affecting visibility and entry/exit.
