Why dive here
With 93+ marine species recorded in the area - including blue whales, dolphins, dwarf minke whales, great white sharks and hammerhead sharks - Ex-HMAS Hobart offers some of South Australia's richest wreck diving. Water ranges 14-21°C, warmest January, February, March.
The Ex-HMAS Hobart, scuttled off South Australia, feels less like a wreck and more like an underwater museum. We love that it’s an accessible wreck dive, sitting upright and pretty intact, with plenty of opportunities to penetrate. You can duck into the engine room, navigate the bridge, or explore the missile launcher, each section offering a different mood. Inside, the light plays through openings, illuminating schools of old wives and sweepers, while outside, big schools of yellowtail scad often swirl around the mast. Our favourite spot is probably the funnel, where you’ll frequently find a giant cuttlefish or two eyeing you curiously. It’s not just the structure; the marine life has really made it home. Nudibranchs crawl over railings, and schools of magpie perch congregate in the darker corners. We’d suggest going on a calm day; South Australian weather can be temperamental, and good visibility really enhances the experience here. It suits divers who appreciate a well-preserved wreck with some current awareness.
Safety Notes
Wreck site - avoid penetration without wreck diving certification. Watch for sharp metal and entanglement hazards.
