Australia joined a U.S.-led coalition in the Iraq War. Declassified documents reveal that the decision to go to war was taken primarily with a view to enhancing its alliance with the United States.
The Australian contribution to the war in Afghanistan has been known as Operation Slipper (2001–2014) and Operation Highroad (2015–2021).
The military history of Australia spans the nation's 230-year modern history, from the early Australian frontier wars between Aboriginal people and Europeans to the ongoing conflicts in Iraq and Afghanistan in the early 21st century. Although this history is short when compared to that of many other nations, Australia has been involved in numerous conflicts and wars, and war and military service have been significant influences on Australian society and national identity, including the Anzac spirit. The relationship between war and Australian society has also been shaped by the enduring themes of Australian strategic culture and the unique security challenges it faces.
The Battle of Timor occurred in Portuguese Timor and Dutch Timor during the Second World War. Japanese forces invaded the island on 19 February 1942 and were resisted by a small, under-equipped force of Allied military personnel—known as Sparrow Force—predominantly from Australia, United Kingdom, and the Dutch East Indies. Following a brief but stout resistance, the Japanese succeeded in forcing the surrender of the bulk of the Allied force after three days of fighting, although several hundred Australian commandos continued to wage an unconventional raiding campaign. They were resupplied by aircraft and vessels, based mostly in Darwin, Australia, about 650 km (400 mi) to the southeast, across the Timor Sea. During the subsequent fighting, the Japanese suffered heavy casualties, but they were eventually able to contain the Australians.
6th Battalion, Royal Australian Regiment is a mechanised infantry battalion of the Australian Army. It was originally raised in Brisbane, Queensland, on 6 June 1965 and has since then served in a number of overseas deployments and conflicts including South Vietnam, East Timor, Iraq and Afghanistan. During the Vietnam War, the battalion earned a US Presidential Unit Citation from the United States when members from 'D' Company participated in the Battle of Long Tan on 18–19 August 1966. The battalion is currently based at Gallipoli Barracks in Brisbane and forms part of the 7th Brigade.
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. 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.
The International Force East Timor (INTERFET) was a multinational non-United Nations peacemaking task force, organised and led by Australia in accordance with United Nations resolutions to address the humanitarian and security crisis that took place in East Timor from 1999–2000 until the arrival of UN peacekeepers. INTERFET was commanded by an Australian military officer, Major General Peter Cosgrove.

HMAS Tobruk was a Landing Ship Heavy (LSH) of the Royal Australian Navy (RAN), based on the design of the Round Table-class of the British Royal Fleet Auxiliary. Planning for the ship began in the 1970s to provide the Australian Army with a permanent sealift capability. She was laid down by Carrington Slipways in 1979, launched in 1980, and commissioned in 1981. She was a multi-purpose, roll-on/roll-off heavy lift ship capable of transporting soldiers, APCs, and tanks, and delivering them to shore via landing craft or directly by beaching.

Australia was a member of the international coalition which contributed military forces to the 1991 Gulf War, also known as Operation Desert Storm. More than 1,800 Australian Defence Force (ADF) personnel were deployed to the Persian Gulf from August 1990 to September 1991, while contingents from the Royal Australian Navy circulated through the region in support of the sanctions against Iraq until November 2001. In August 1990, two frigates HMAS Adelaide and HMAS Darwin and the replenishment ship HMAS Success left for the Persian Gulf. HMAS Success had no air defences, so the Army 16th Air Defence Regiment was embarked. On 3 December 1990, HMAS Brisbane and HMAS Sydney (IV) relieved HMAS Adelaide and HMAS Darwin. On 26 January 1991, HMAS Westralia replaced HMAS Success. A Navy clearance diving team was also deployed for explosive ordnance disposal and demolition tasks. Australian ships were in danger of sea mines and possible air attacks. In a number of recorded incidents, HMAS Brisbane encountered free floating mines, on one occasion narrowly avoiding a collision. Both HMA Ships Brisbane and Sydney encountered significant air threat warnings from Iran and Iraq throughout the initial period of the commencement of the Desert Storm Campaign. The detection of land based Silkworm anti-ship missiles from Iran throughout the campaign also added to the challenges for both crews as well as the multi-national Naval Forces.
The British Commonwealth Far East Strategic Reserve was a joint military force of the British, Australian, and New Zealand armed forces. Created in the 1950s and based in Malaya, the FESR was conceived as a forward defence point for Australia and New Zealand, while protecting Commonwealth interests in the Southeast Asian region from both internal and external communist threats. The FESR was made up of an infantry brigade and an aircraft carrier group, supported by squadrons of aircraft.
The ANZAC Battle Group was an Australian-led battle group deployed to Timor Leste as part of Operation Astute. The battle group was established in September 2006 and comprised several rifle companies, including a company from the New Zealand Army, and sub-units of other Australian Army units.

The 11th Brigade is an Australian Army brigade which currently comprises most Australian Army Reserve units located in Queensland. The brigade was first formed in early 1912 following the introduction of the compulsory training scheme. Later, as part of the 3rd Division and saw action during World War I on the Western Front as part of the First Australian Imperial Force. In the interwar years, the brigade was re-raised with its headquarters in Brisbane.
The Battle of Same was fought in the village of Same in Timor Leste, 50 kilometres (31 mi) south of the capital Dili, between Australian Special Forces and Petitioner rebels under the command of Alfredo Reinado. The operation occurred under the auspices of Operation Astute, being the deployment of Australian forces in the wake of 2006 East Timorese crisis, and resulted in the Australians successfully securing the target compound and defeating the small rebel force, before the assault was called off by the Timor Leste government. Reinado and nine other rebels subsequently evaded the Australian cordon, however, and made good their escape into the mountains.
The logistical support of the multinational International Force East Timor (INTERFET) peacekeeping mission in 1999 and 2000 involved, at its peak, 11,693 personnel from 23 countries. Of these 5,697 were from Australia, making it the largest deployment of Australian forces overseas since the Vietnam War. INTERFET was unusual in that it was led by Australia, casting the country in a wholly unfamiliar role. The logistics and support areas of the Australian Defence Force (ADF) had been subject to deep cuts in the 1990s. The ADF had not anticipated being committed to such a large peacekeeping mission, and was unprepared to support an Australian force projection of this size, much less act as lead nation of an international coalition.
