Wilson Promontory offers a genuinely varied diving environment across reef, wall, cave, wreck and seagrass habitats, with depths running from the shallows right down to 50 metres. Visibility is highly variable, so conditions can shift significantly between visits. Currents are likewise unpredictable, and cold water combined with surge demands a proper wetsuit and some experience reading conditions before you jump in. The marine life rewards patience: weedy seadragons move through seagrass beds, Australian fur seals are curious and playful around the rocks, and the reef structure holds red velvetfish, Port Jackson sharks, eastern blue groper, and dense growths of sponges, sea tulips and lace corals.

November through May brings the most reliable conditions, so plan accordingly and always check the forecast the morning of your dive as swell and surge can close sites quickly. Boat traffic is a genuine concern, so tow a surface marker buoy on every dive.
Most premier dive sites are offshore around the islands and require boat access. There is no public boat ramp within the national park; vessels are typically launched from the beach at Norman Bay, which requires a specific permit from Parks Victoria. Some commercial boat charters operate in the area. Some shore diving and snorkelling is possible from sites like Pillar Point near Tidal River.
