The 47th Battalion was an infantry battalion of the Australian Army. It was originally raised in 1916 for service during the First World War. The battalion then took part in the fighting in the trenches of the Western Front in France and Belgium, before being disbanded in early 1918 to provide reinforcements for other Australian units that were suffering from a manpower shortage following the German spring offensive. In 1921, it was re-raised as a part-time unit of the Citizens Force, which later became the Militia. During this time it was based in south-east Queensland and in 1927 it became known as the "Wide Bay Regiment". During the Second World War the 47th Battalion took part in fighting in New Guinea and Bougainville, before being disbanded again in January 1946. Later, the battalion was re-raised before eventually being subsumed into the Royal Queensland Regiment in 1960.

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.
