The steamer Karitane, built in 1903, was wrecked on Christmas Day 1921 after striking the cliffs of Deal Island in fog while carrying copper ingots, and was beached in Squally Cove. The Marine Life Network guide rates the site 7 out of 10: the shell is flattened on a north-south line, with the bow on the pebbly beach and the stern about 80 m to the south, and the heavily salvaged wreck still shows machinery, the boiler, prop shafts and steel plate sections. It was famously salvaged by the professional diver 'Johnno' Johnson, who later recovered gold from other wrecks, and unauthorised salvors caused dynamite damage. Schools of fish frequent the wreck, and some steel pieces lie on the foreshore. The guide gives a depth range of 1-70 m, which presumably refers to the surrounding seabed rather than the wreck itself. The Marine Life Network guide's descriptions are the only detailed published account, so expect some changes in the decades since and plan to explore.

The Kent Group is one of the most isolated island groups in Australian waters, protected as the Kent Group National Park on land, with the surrounding waters managed as a marine reserve. It sits in the middle of Bass Strait where warm and cool currents mix, and its granite walls and clear water support rich invertebrate growth rarely seen by divers. The historic Deal Island lighthouse (1848), once the highest in the southern hemisphere, overlooks the anchorages.

With no facilities beyond the caretakers' station and a long passage back to the mainland or Flinders Island, any diving injury is a serious emergency requiring aeromedical evacuation, most likely to Melbourne's Alfred Hospital. Diving here is for experienced, completely self-sufficient expedition divers.

The Kent Group (Deal, Erith and Dover islands and outliers) lies in central Bass Strait about 55 km north-west of Flinders Island and roughly 90 km south of Wilsons Promontory. There is no scheduled transport: divers arrive on private yachts or expedition charters from Port Welshpool (Victoria), Flinders Island or north-east Tasmania, a passage of 6-12 hours depending on departure point. Murray Pass, the channel between Deal and Erith islands, offers the main anchorages (West Cove, East Cove); volunteer caretakers live on Deal Island, and landing and camping are managed by the Parks and Wildlife Service.

The wreck lies in Squally Cove on Deal Island, reached by tender from the Murray Pass anchorages in calm weather.

Central Bass Strait is notorious for sudden gales: westerly and south-westerly fronts and strong easterlies can arrive with little warning, and Murray Pass runs a strong tidal current that sweeps the headlands of West and East coves. January-April offers the most settled weather; after a gale, strong surface currents persist through the strait. Anchorages in Murray Pass give shelter from most directions except along the pass.

Squally Cove is exposed; dive only in calm conditions.

Start at the bow on the pebbly beach and follow the flattened shell south about 80 m to the stern, viewing the boiler, machinery and prop shafts. Turn the dive at half gas (thirds where current or overhead sections are involved), deploy an SMB before surfacing for the live-boat pick-up, and complete a 3-minute safety stop at about 5 m where depth allows.

No operator. Visited only by private yachts and occasional expedition charters (typically from Port Welshpool in Victoria or from Flinders Island); full self-sufficiency required, including compressor or ample cylinders.
