Meet the site
Kakariki was a steel interstate trader of 1,887 dwt built by Cochrane and Sons at Selby, Yorkshire, in 1926, 58 m (190 ft) long, one of a class of small steamers that carried timber, ore and general cargo around the Tasmanian and Victorian coasts. On 29 January 1937 she was inbound from Strahan on Tasmania's west coast with timber and ore when, in the fairway off Williamstown, she collided with the steamer Caradale. The Caradale struck her on the starboard side between the forecastle and the mess room and tore a hole 28 feet wide; the Kakariki sank in three minutes and five of her crew died. The wreck lay in the main channel until 1945, when what was left after salvage was moved in pieces and dumped in deeper water off Point Gellibrand. What survives is a scatter rather than a ship. Parts of the mast, the bridge structure and the bow lie on a muddy bottom in 8–10 m in two debris fields about 80 m apart, festooned with mussels and sponges and home to the fish of the northern bay – snapper in season, flathead on the mud, leatherjackets and small wrasse in the steel. Visibility is usually one to five metres and a reel from the anchor is the only sensible way to explore. It is dived rarely, by Williamstown and inner-Melbourne divers with their own boats, and is not on any charter schedule. The Kakariki matters more for what she represents than for what she offers underwater: she is the port of Melbourne's worst peacetime collision, a grave for five seamen and the reason a section of channel was cleared in 1945. Divers who want a quick, unusual historic wreck fifteen minutes from the West Gate Bridge will find her worth one visit on a clear flood tide; anyone after structure and visibility should go to the Uralba or the Heads.
