The 27th Brigade was a brigade-sized infantry unit of the Australian Army. The brigade was the last Second Australian Imperial Force infantry brigade raised for service during World War II. Initially assigned to the 9th Division, the brigade was transferred to the 8th Division shortly after it was raised. Training was undertaken around Bathurst, New South Wales throughout early 1941, before the brigade was sent to British Malaya in August 1941 to reinforce the 22nd Brigade, which had been dispatched earlier in the year. Following the Japanese invasion of Malaya, the brigade went into action in January 1942, taking part in the fighting along the western side of the Malay Peninsula. Its main action during this period came around Muar before the withdrawal to Singapore. In February, the brigade took part in the short lived Battle of Singapore. When the garrison surrendered on 15 February, the majority of the brigade's personnel were taken prisoner. They subsequently spent the remainder of the war in captivity before being released in August 1945.
