Ocean Divers

Ocean Divers covers recreational and technical training with access to Port Phillip diving, including the HMAS Canberra and the walls at the Heads — the sites that define Victorian diving.

HMAS Canberra is Victoria's signature wreck. The former guided missile frigate was scuttled off Ocean Grove in 2009 and sits at approximately twenty-eight metres. Visit Victoria's own guidance is instructive: divers need an industry-recognised entry-level qualification *and* experience appropriate for the dive. That second requirement is the one people overlook.

A certification card identifies training completed. It does not demonstrate recent experience in cold water at twenty-eight metres with reduced visibility, current and the task loading that a thick suit adds. At 138 metres long the wreck cannot be covered in one dive, which is part of its appeal — divers return repeatedly and see different sections.

Port Phillip Heads is the other major destination, and it is entirely tide-governed. Most Heads diving happens in a limited slack-water window that shifts daily, and operators who insist on that scheduling are demonstrating competence rather than inflexibility.

Technical training is documented, which fits the terrain — the walls run from twelve metres to beyond ninety, giving divers somewhere genuine to apply decompression and Trimix training.

HMAS Canberra is also a good illustration of why experience matters more than certification. At twenty-eight metres in cold water with reduced visibility, a diver with twenty warm-water dives and one with two hundred cold-water dives are in genuinely different situations.
