Since the 15th century, the town area including other parts of Labuan were under the Bruneian Empire. Its history dates back to the time when the island was ceded by Sultan Omar Ali Saifuddin II to the British. Rodney Mundy, a British naval officer, later visited the island under the name of Queen Victoria. The island was then occupied by Japan from 3 January 1942 until June 1945 and governed as part of the Northern Borneo military unit by the Japanese 37th Army. During the Battle of Labuan it was liberated by the 9th Division of Australian Imperial Force on 10 June 1945 and placed under a British Military Administration until 15 July 1946, when it was incorporated into North Borneo Crown Colony. During this time, the Crown Colony government re-established much of the infrastructure that had been destroyed during the war. The island later became part of the state of Sabah and Malaysia in 1963 before the state government of Sabah ceded the island to the federal government in 1984. It was declared an international offshore financial centre and free trade zone in 1990 to assist the development of Victoria.
