Shark Bay diving is expedition style: you come for dolphins, dugongs, and World Heritage scenery, then pick a weather window for a big boat day. Denham based operators such as Shark Bay Eco Tours (PADI) run trips toward Steep Point and Dirk Hartog Island for walls, bommies, and sanctuary-zone fish life. Depths commonly sit around 4 m to 24 m, and water temperatures are often about 20°C to 26°C. Expect long runs, variable conditions, and occasional cancellations for swell or wind, so keep your schedule flexible and build a strong Plan B.
Steep Point Wall (The Dutchman)
A flagship outeredge site near mainland Australia's westernmost point.
A ledge dive in a sanctuary zone off Dirk Hartog Island where fishing is not permitted, often translating to more confident big fish.
Pristine bommies that can be a magnet for rays, turtles, and occasional dugong or manta sightings.
Cabbage Patch Cleaning Station
A hard coral patch on white sand that functions as a cleaning station, with frequent ray and turtle traffic.
A shallow horseshoeshaped ledge where crayfish are commonly spotted.
A compact wall feature with coral cover and turtle resting nooks.
