SS Zealandia, nicknamed "Z" (or "Zed"), was an Australian cargo and passenger steamship. She served as a troopship in both World War I and World War II. Zealandia transported the Australian 8th Division. Her crew were the last Allied personnel to see , which was lost with all hands in 1941. Zealandia was sunk in the air raids on Darwin of 19 February 1942. Building John Brown & Company of Clydebank, Scotland, built Zealandia for Huddart Parker & Co of Melbourne, launching her on 20 November 1909 and completing her in May 1910. She had 21 corrugated furnaces with a total grate area of heating seven single-ended boilers with a total heating surface of . They supplied steam at 215 lbf/in2 to two four-cylinder quadruple expansion engines, each of which drove one of her twin screws. Early civilian service In 1910–13, she was chartered by the Union Steam Ship Company of New Zealand mainly for use on the trans-Tasman route, but also undertaking voyages to ports as distant as Fremantle and Vancouver. Huddart Parker then used Zealandia on the Melbourne–Fremantle route. World War I In May 1918, Zealandia was requisitioned as an Allied troopship. She was among the ships used to transport the American Expeditionary Force from the east coast of the United States to France. After the armistice, she carried troops on the Liverpool–Sydney route. In 1919, she resumed her commercial role with Huddart Parker. World War II On 29 June 1940, Zealandia embarked part of the 8th Division, the 2/21st Battalion, later known as Gull Force, at Sydney and took it and other units to Darwin. Zealandia transported another part of the 8th Division, Lark Force (otherwise known as the 2/22nd Battalion), to Rabaul, leaving Sydney on 19 April 1941. Following that voyage, Zealandia went to Noumea, New Caledonia and transported Free French troops to Sydney. In mid-1941, Zealandia took the main body of the 8th Division, their stores, and equipment to Singapore, where the main body of the 8th was surrendered to Japanese forces in February 1942. After several other war-related voyages, in November 1941 Zealandia visited several Australian ports en route to Singapore. A labour dispute involving some crew members caused her and HMAS Sydney to be delayed in leaving Fremantle, whence Sydney escorted Zealandia to Sunda Strait. Zealandias crew were the last Allied personnel known to have seen Sydney, which was sunk by the and
