K-IX SubmarinePrint Page Print this page

A plaque commemorates the loss of the K-IX submarine. The NSW Heritage Office initiated the installation of a plaque commemorating the loss of the submarine K IX at Submarine Beach, following its relocation of the wreck site in 2000. 

Funding support was obtained from the Consulate of the Kingdom of the Netherlands and Great Lakes Council.  The March 23, 2001 unveiling ceremony by Urban Affairs & Planning Minister, Dr Andrew Refshauge, involved some 120 guests. Established at the lookout adjacent to the Sugarloaf Point Lighthouse at Seal Rocks, guests included Mr Ed Reitsma, Consul General of the Kingdom of the Netherlands and Great Lakes Council staff.  Representatives of the Netherlands Ex-Servicemen & Women's Association of Australia, the Submarines Association of Australia, the Naval Association of Australia, DL&WC, NPWS, historical societies, local school children and residents, were also prominent. 

The former Royal Netherlands (Dutch) Navy submarine K-IX was built in 1922 at the K.M. de Shelde yard at Flushing, Holland. In a remarkable career, the submarine was finally wrecked on a desolate beach south of Treachery Head, Seal Rocks in 1945. It is the only known submarine wreck in New South Wales, apart from the Japanese midget submarine that was one of three that attacked Sydney Harbour. Escaping the Japanese advance of Java in 1942, the K-IX fled to Fremantle and was finally based at Sydney. The submarine was extensively damaged when a torpedo passed underneath it and destroyed the ex-ferry Kuttabul during the Japanese midget submarine raid of 31 May, 1942. Commissioned as a unit of the Royal Australian Navy, the submarine became an expensive liability requiring constant servicing. Finally paid off in 1944, the hull was converted to carry diesel oil. The vessel ran ashore on 8 June, 1945 after slipping the tow of its transport, the RNN Abraham Crijnsen, on a voyage to Brisbane. The wreck was bought at auction on 20 July, 1945 for £985 but salvage attempts were incomplete.  The K-IX wreck was last sighted in the 1980's following sand scouring, but is usually buried under several metres of beach sand. The submarine lies in the tidal zone of Submarine Beach, named in honour of the vessel's resting place.
