 in 1901. Some of colonial forces, which served the states of Australia at the time, were gradual united into federal units between 1899 to 1903; thus forming the beginning of the Australian Army. The colonial armies were officially united as the Commonwealth Forces in the Defence Act of 1903. Since then the Australian Army has changed to suit to needs of Australia; with particular changes occurring during, and following, the World Wars, Korean War, Vietnam War and Gulf War.

During the economic depression of the early 1890s, large-scale strikes in various colonies were met with governments mobilising and/or threatening to use militia against strikers. This was very unpopular and led to successful and historically-significant campaigns against the formation of standing, regular forces. The "two armies" system was established whereby the only infantry units would be militia, although permanent artillery and other support units remained.

The colonies dispatched 200 men from Victoria, 260 from New South Wales and the South Australian ship HMCS Protector, under the command of Captain William Creswell. Amongst the naval contingent from New South Wales were 200 naval officers and sailors and 50 soldiers headquartered at Victoria Barracks, Sydney who originally enlisted for the Second Boer War. The soldiers were keen to go to China but refused to be enlisted as sailors. The NSW Naval Brigade objected to having soldiers in their ranks. The Army and Navy compromised and titled the contingent the NSW Marine Light Infantry.

1901–14

As the Boer War raged, the Commonwealth of Australia was founded on 1 January 1901. On 1 March, 28,923 colonial soldiers, being 1,457 professional soldiers, 18,603 paid militia and 8,863 unpaid volunteers, were transferred to the new Australian Army. However, the individual units continued to be administered under the various colonial Acts. Maj. Gen. Sir Edward Hutton

The Defence Act of 1903 brought all of the units under one piece of legislation; more significantly, it prevented the raising of standing infantry units and specified that militia forces could not be used in industrial disputes, and could not serve outside Australia. The vast majority of soldiers remained in militia units, now known as the Citizen Military Forces (CMF).

In January 1958, 3RAR began Operation Ginger, a major operation designed to disrupt the food supply to the communist forces. Ginger continued until April 1959 when Perak was declared a safe area. The battalion was withdrawn from operations in September 1959, returning to Australia in October. It had four killed during its tour

In October 1959, 3RAR was replaced by 1RAR. Following a month spent climatising to the jungle, 1RAR participated in Operation Bamboo, a deep jungle search near the Thai-Malay border. This operation met with little success, as insurgents could cross over the border into Thailand, where they could not be followed. In April 1960, 1RAR began Operation Magnet, the first operation in which Australian forces were able to cross the border into Thailand. However, Magnet did not result in any engagements.

. The multi-national force was to comprise of approximately 8,000 military personnel and a large contingent of Civilian Police. However, due to significant difficulties within the UN and in having South African forces withdrawn, the UN force did not deploy until 1989.

Australia deployed a combat engineer force of approximately 310 all ranks as part of the military force. The Australian contingent provided engineering support to the UN Force throughout its deployment. Tasks included numerous major construction projects including road and airfield construction, buildings, barracks, schools and other infrastructure to support the UN. The Australians also provided a wide range of assistance to the Namibian people by constructing a variety of civil projects.

Of note was the task of battlefield clearance after twenty years of warfare. Much of Namibia was in conflict and resulted in millions of land mines being laid around civilian communities and areas along the northern land border. The removal of these land mines was left to the South African Army

, however, tens of thousands remained when RSA forces finally withdrew in 1990. The task then fell to the Australians. Despite the significant danger of this task, a 98% success rate was achieved with many civil communities becoming safe for the first time in decades.

The Australia force rotated once after six months deployment and provided continuous engineer support to the UN and Namibia. The force achieved its mission without sustaining any fatalities, making it one of the few military units in UNTAG to do so. Australia's contribution to UNTAG was a success and, as the first deployment of troops to a war zone since the Vietnam War, paved the way for future deployments.
