The 33rd Brigade was a formation of the Australian Army established at the end of World War II. Formed in August 1945 at Morotai Island, it consisted of three Australian Imperial Force infantry battalions that were raised for occupation duties in the Dutch East Indies following Japan's surrender. After deployment to Timor and Ambon, it returned to Morotai when Dutch colonial rule was re-established. It was disbanded in early 1946 and its personnel demobilised.
