Meet the site
The Geltwood is one of South Australia's most tragic shipwrecks and, according to the Marine Life Network, one of its most spectacular wreck dives – on the rare days it can be dived. An iron, three-masted barque of 65.7 m and 1,056 net tons, she was launched on 18 January 1876 by R. Williamson & Sons at Harrington and was completing her maiden voyage from Liverpool to Melbourne when, in a storm on 14 June 1876, she struck a reef, capsized and broke up off the Canunda coast. All 31 passengers and crew were lost. Authorities only learned of the wreck on 5 July, after nearly three weeks in which washed-up cargo was looted from the beaches.
The wreck lies about 1.6 km offshore near the northern end of Lake Bonney, 16 km south-east of Southend. Divers who have reached it describe a recognisable hull with masts, yards, anchors and concreted cargo – unusual for an iron wreck on such an exposed coast. The Marine Life Network is candid that it is undiveable most days because of continual swell, and there is no charter.
Anchors and memorabilia are displayed at the Geltwood anchor memorial on Cape Buffon Drive at Southend, the Millicent Living History Museum and the Beachport museum, and the wreck's 150th anniversary in 2026 prompted a documentary and commemorations. The site is a protected historic shipwreck: look, photograph and leave everything in place. It suits experienced, self-sufficient boat divers who can wait for a genuine flat calm on the Southern Ocean.
Research this site before booking Stored site notes may be historical. These questions highlight gaps without turning old instructions into a current dive plan.
Geltwood Wreck is recorded as Wreck in Limestone Coast. The listed access is boat. Confirm the actual meeting point, route and permission to visit; a map pin does not establish any of these.
Topics flagged by the stored research
These are questions prompted by the existing notes, not a verified or complete hazard assessment.
- Other water users
- Ask about vessel activity, exclusion areas and the agreed surface arrangements.
- 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.
