The 29th Brigade was an infantry brigade of the Australian Army that was raised for service during World War II. Formed in late 1941 as part of the Militia, the brigade was initially formed for home defence in response to Japan's entry into the war. Composed of three Queensland-based infantry battalions and various supporting elements, the brigade initially undertook defensive duties around Townsville in 1941–1942 before deploying to New Guinea in 1943. There, the brigade undertook garrison duties before taking part in the Salamaua–Lae campaign. After a period of almost 18 months overseas, the brigade's elements were returned to Australia for a period of rest and reorganisation before later being assigned to the Bougainville campaign in 1944–1945. After the war, the brigade was disbanded in December 1945, along with its component units. History Raised on 20 December 1941 under the command of Brigadier Thomas Louch for service during World War II, the 29th Brigade was formed as part of the Militia, Australia's part-time military force. The brigade's headquarters opened in January 1942 at Ascot, Queensland, and the formation was initially tasked with undertaking defensive duties in response to concerns about a possible invasion from the Japanese. In March 1942, two of the brigade's three infantry battalions—the 42nd and 47th Battalions—began concentrating in Tiaro where they formed part of the 5th Division. The 25th Battalion remained in Toowoomba, to reinforce the 7th Brigade. After units of the Second Australian Imperial Force began to arrive in Australia to reinforce the east coast, in April 1942 the brigade began moving to Townsville. There, the 15th Battalion was assigned to the brigade, which took up defensive duties, constructing defences along line between Giru and Rollingstone. During the Battle of Coral Sea, when the threat of invasion seemed imminent, the brigade was moved to the coast, issued ammunition for the first time and stood-to in preparation for a Japanese landing. In the event, this invasion did not occur and the brigade was stood down, returning to more mundane garrison duties, before moving to Mount Spec, to undertake jungle training in preparation for overseas service. In January 1943, with the threat of invasion over, the brigade was deployed to New Guinea, under the command of Brigadier Ray Monaghan. The 42nd Battalion moved to Rabi, near Milne Bay, to relieve the 7th Brigade's 61st Battalion, which had fought a successful defensive action there against the Japanese the
