The Japanese army occupied North Borneo from 1942-1945. In June 1945 the Australian 9th Division landed in Brunei and liberated much of North Borneo before the end of the war. North Borneo was placed under British Military Administration (BMA) until  the British North Borneo Company decided to sell its interests to the British government in July 15, 1946 to become the British crown colony.
