Why dive here
Wreck of HMAS Perth is a wreck dive where divers can encounter mantis shrimp. Water ranges 29-32°C, warmest April, May, June.
The HMAS Perth wreck isn't just a dive, it’s a tangible piece of history sitting upright on the seabed off Sumatra. You drop down, and the sheer scale of this cruiser hits you. It’s a somber experience, knowing the fate of her crew in the Battle of Sunda Strait. We love exploring her gun turrets, still mostly intact, and imagining the chaos of that night. What makes the Perth special is how accessible her history feels. You can swim through parts of the superstructure, peering into what were once vital compartments. Corals have started to colonise the metal, soft dendronephthya corals and sponges adding splashes of colour to the grey steel. We've seen schools of fusiliers here, sometimes so thick they briefly block out the light filtering down from the surface. Look closely, and you’ll spot a few reef sharks patrolling the perimeter, and we’ve even come across giant groupers lurking in the shadows of the bow. It’s a dive that suits those with a deep appreciation for history and a love for exploring large, dramatic structures. Expect strong currents at times, which only adds to the adventurous feel.
