HMAS Perth II is a decommissioned warship sitting on the seabed off Western Australia, resting at depths from 5 to 38 metres. The wreck is substantial enough to reward multiple dives, with visibility ranging from 10 to 25 metres giving you good sightlines along the hull. Resident marine life includes blue groper, blue devils, pink snapper, queen snapper, samson fish and break sea cod, while wobbegong sharks and other sharks are regular visitors. Nudibranch and tasmanian blenny add smaller-scale interest for those who take their time. Current is generally mild, but the deeper sections push into decompression diving territory, so solid buoyancy control and dive planning are essential before heading down.

Keep your bottom time at depth conservative on your first dive down to the lower sections of the wreck, as nitrogen narcosis can become a factor and the conditions can change your available no-decompression time quickly. Check locally for current conditions before you go, as visibility can vary significantly.
