The SS Corangamite was a steel screw steamer built at Wallsend-on-Tyne in 1885 for the intercolonial passenger and cargo trade – about 91 m (300 ft) long and 2,420 gross tons, a large and modern ship for her day. On 6 December 1886, bound from Melbourne to Sydney with about 100 passengers and 40 crew under Captain Le Neveu, she ran aground at 8 am in dense fog on a headland in the Wreck Bay area.

Calm seas allowed an orderly evacuation, and most passengers were taken by the ship's boats to Ulladulla. Salvors worked for weeks with two tugs, the Eagle and the Stormcock, and several pumps, but on 22 December heavy seas broke her up and she became a total loss. The South Coast Register places the wreck on the south-west side of St George Head, and the Lady Denman Museum notes that the site is locally known as 'Corangamite'.

Today little remains. The wreck lies in about 15 m, and ballast blocks are described as the only visible evidence of the ship, along with scattered remains mentioned by other sources. It is therefore a historical site for divers interested in the maritime past of Wreck Bay – a stretch of coast whose very name records how many ships came to grief here – rather than a structural wreck dive. The surrounding reef is typical of the exposed Booderee coast. Because it is rarely dived and not well documented, marks and details should be confirmed locally. It is a protected historic shipwreck; nothing may be removed.

Launch at Murrays Beach (Booderee) or Huskisson and run south along the Booderee coast past Steamers Beach to St Georges Head (40–50 minutes from Huskisson); the remains lie off the south-west side of the head in about 15 m. Alternatively launch at Sussex Inlet in calm conditions and run north-east. Local marks are needed – the site is not widely published.

The southern headland of Jervis Bay (Booderee National Park's ocean coast) faces east and south-east and takes the full force of southerly and south-easterly swell. These sites need swell under about 1–1.5 m and are best in westerly or north-westerly winds – typically winter – when the cliffs give a lee. North-easterly winds are generally fine on this coast but make the run back across the bay choppy.

Visibility is usually good (15–25 m) in oceanic water; currents can be strong further offshore. The south-west side of St Georges Head is sheltered from north-easterly winds but exposed to southerly swell.

Descend on the marks and search the reef and sand at about 15 m for the ballast blocks and scattered plates, working in an expanding pattern from the anchor.
