Meet the site
The Admella disaster of August 1859 remains South Australia's worst maritime tragedy. The iron screw steamer, built in 1857 at Port Glasgow and about 60 m long, was on passage from Adelaide to Melbourne when she struck Carpenter Reef off Cape Banks and broke up. Of the 113 people aboard only 24 survived – including one woman, Bridget Ledwith – after clinging to the wreck for a week while rescuers on shore and in boats were repeatedly beaten back by the surf. 89 people died, 14 of them children. The rescue attempts, reported daily, gripped the colonies and led to a public reward fund and improvements in coastal lifesaving; the Cape Banks lighthouse followed.
The wreck lies in about 5 m on the reef, broken into pieces and scattered by more than 160 years of Southern Ocean swell. What remains is iron plating, machinery and fittings among kelp and limestone, colonised by the same life as the surrounding reef. The site is protected under the Commonwealth Historic Shipwrecks Act 1976 (now the Underwater Cultural Heritage Act 2018), so nothing may be removed.
Practically, it is one of the hardest dives in the region to get: Carpenter Reef is very exposed and diving is difficult in all but the calmest seas, there is no charter, and surge over the shallow reef can be violent. Most visitors experience the story on land, via the Admella Discovery Trail, the memorial cairn at Cape Banks and museum displays. It suits experienced local boat divers with an interest in maritime history who can pick a rare flat day.

Topics flagged by the stored research
These are questions prompted by the existing notes, not a verified or complete hazard assessment.
- Water movement
- Ask how swell and local exposure affect the proposed entry, exit and route.
Historical access notes exist for this record, but have not been independently verified for current use. Request current directions from the operator or site manager rather than following an old entry description.
