The 3rd Brigade is a combined arms brigade of the Australian Army, principally made up of the 1st and 3rd Battalions of the Royal Australian Regiment (1 and 3 RAR). Initially raised in 1903 as part of the post-Federation Australian Army, it was removed from the order of battle in 1906 following the restructure of the field force. It was re-formed in 1914 for service during World War I, taking part in the fighting at Gallipoli and on the Western Front in Europe. During World War II the brigade was used in a defensive role before it was disbanded in 1944. It was re-raised in 1967 for service during the Vietnam War and later went on to provide the nucleus of the deployment to East Timor during the Australian-led intervention in 1999. The brigade is currently based at Lavarack Barracks in Townsville, Queensland. History Post-Federation Following the Federation of Australia in 1901, the structure of the new Australian Army was approved in 1903. Included in the new field force were three infantry brigades of both militia and volunteer personnel, each of which consisted of four infantry regiments, three field artillery batteries, a company of engineers, as well as a field hospital and veterinary and supply units in support. The 1st Brigade was raised in New South Wales and the 2nd in Victoria, each consisting primarily of troops recruited from those states respectively, while the 3rd Brigade was based in Queensland from troops based in the remaining states of Queensland, Tasmania, South Australian and Western Australia. Units of the brigade included 9th, 10th, 11th and 12th Australian Infantry Regiments. However, by 1906 the field force had been restructured into just two infantry brigades, along with five light horse and four mixed brigades. As a consequence the 3rd Brigade was removed from the Australian Army's order of battle, and its units became part of the mixed Queensland Infantry Brigade established at that time. In 1912, following the introduction of the compulsory training scheme, the brigade was assigned to the 1st Military District. At this time, the brigade's constituent units were located across south-east Queensland and northern New South Wales including Brisbane, Ipswich, Toowoomba, Warwick, Lismore, Casino and Grafton. World War I The 3rd Brigade was re-formed in August 1914, as part of the Australian Imperial Force (AIF) which was raised for service overseas during World War I. As part of the 1st
