Welcome to the Military history of Australia portal!
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 six British colonies in Australia participated in some of Britain's wars of the 19th century. In the early 20th century, as a federated dominion and later as an independent nation, Australia fought in the First World War and Second World War, as well as in the wars in Korea, Malaya, Borneo and Vietnam during the Cold War. In the Post-Vietnam era Australian forces have been involved in numerous international peacekeeping missions, through the United Nations and other agencies, including in the Sinai, Persian Gulf, Rwanda, Somalia, East Timor and the Solomon Islands, as well as many overseas humanitarian relief operations, while more recently they have also fought as part of multi-lateral forces in Iraq and Afghanistan. In total, nearly 103,000 Australians died during these conflicts. (Full article...)
The area command continued to operate after the war, but its assets and staffing were much reduced. Its responsibilities were subsumed in February 1954 by the RAAF's new functional commands: Home (operational), Training, and Maintenance Commands. The area headquarters was disbanded in December 1956 and re-formed as Headquarters RAAF Townsville. (Full article...)

The George Cross (GC) is the highest civil decoration for heroism in the United Kingdom. Australia as a member of the Commonwealth of Nations through the Governor-General of Australia was eligible to recommend awards, with the last GC recommended in 1972, on the advice of the Australian Prime Minister, for the late Jack Emanuel GC. Each governor of the six Australian colonies, when achieving self-government in the second half of the nineteenth century, had the power on the advice of the colonial premier to recommend awards. This power was retained by colonial governors who became state governors when Australia federated on 1 January 1901. The last Australian recommendation for the GC was made by the State Governor of Victoria in 1978 for the award to Constable Michael Kenneth Pratt.
Australian prime minister Paul Keating, on 5 October 1992, following more than two years of negotiations with Australian State governments, announced Australia would make no further recommendations under the Imperial honours system. British honours awarded to Australians, including the GC, after the announcement, would be treated as foreign awards. The highest civil decoration for heroism in Australia is the Cross of Valour instituted by letters patent within the Commonwealth of Australia and its Territories on 14 February 1975 when the Australian honours system was inaugurated.

Operation Kita (北号作戦, Hoku-gō sakusen, "North") was conducted by the Imperial Japanese Navy (IJN) during the Pacific War in February 1945. Its purpose was to return two Ise-class hybrid battleship-aircraft carriers and four escort ships to Japan from Singapore, where they had been based since November the previous year. The movement of the Japanese force was detected by the Allies, but all attempts to attack it with submarines and aircraft failed. Nevertheless, as a result of the intensifying Allied blockade of Japan, the Ise-class battleship-carriers and their escorts were among the last IJN warships to safely reach the country from the Southwest Pacific before the end of the war.
Before departing Singapore, the Japanese ships, which were designated the Completion Force, were loaded with supplies of oil and other important raw materials. This formed part of an effort to run increased quantities of supplies through the Allied blockade of Japan before the country was cut off from its empire. The Allies had learned of the Completion Force's composition and goals through intelligence gained from decrypting Japanese radio signals, and plans were developed for coordinated attacks on it by submarines and United States Army Air Forces (USAAF) aircraft. As part of these preparations, 26 submarines were eventually positioned along the ships' expected route. (Full article...)
In 1940, he joined the Royal Australian Naval Volunteer Reserve (RANVR) for service in World War II. Quickly sent back to the United Kingdom, he served on several shore establishments before being sent to British India as a naval mine clearance specialist. He returned to the UK in late 1944, and in April 1945 he was given command of a naval party responsible for mine clearance in the recently captured Bremen Harbour in Germany. He displayed exceptional courage in defusing three mines under very difficult conditions between 8 and 19 May 1945, which resulted in him being awarded the George Cross. (Full article...)
Thomas Charles Richmond Baker, DFC, MM & Bar (2 May 1897 – 4 November 1918) was an Australian soldier, aviator, and flying ace of the First World War. Born in Smithfield, South Australia, he was an active sportsman in his youth and developed a keen interest in aviation. He was employed as a clerk with the Bank of New South Wales, before he enlisted in the Australian Imperial Force in July 1915, for service in World War I. Posted to an artillery unit on the Western Front, he was awarded the Military Medal for carrying out numerous repairs on a communications line while subject to severe artillery fire. In June 1917, Baker was awarded a bar to his decoration for his part in quelling a fire in one of the artillery gun pits that was endangering approximately 300 rounds of shrapnel and high explosive.
In September 1917, Baker applied for a position as a mechanic in the Australian Flying Corps. He was instead selected for flight training, and was posted to courses in the United Kingdom. He graduated as a pilot and was commissioned a second lieutenant in March 1918. Posted for active duty in France that June, Baker joined the ranks of No. 4 Squadron AFC. Over the next four months, he rose to the rank of captain and was credited with bringing down 12 German aircraft. He was shot down and killed on 4 November 1918. In February 1919, he was posthumously awarded the Distinguished Flying Cross. (Full article...)
The Leeuwin class is a two-ship class of hydrographic survey vessels operated by the Royal Australian Navy (RAN). Leeuwin and Melville were ordered from NQEA in 1996, and were commissioned in 2000. The ships are capable of charting waters up to 6,000 metres (20,000 ft) deep, carry three Fantome-class survey boats, and could operate an AS 350B Squirrel helicopter. In addition to surveying duties, since 2001 both vessels have been used to supplement the RAN patrol force. Leeuwin is based at HMAS Cairns, while Melville was decommissioned in August 2024.

Over a 41-year career, Sinclair saw active service in Korea, Malaysia, Vietnam, and in relief operations following Cyclone Tracy, and commanded the naval base HMAS Penguin. He later rose to high command, serving as Director of Naval Plans and as chief project officer during the establishment of the tri-service Australian Defence Force Academy, and then serving as its first commandant. In 1987, he was appointed Flag Officer Commanding HM Australian Fleet, which was redesignated as Maritime Commander Australia the following year. In 1989, he was appointed as Deputy Chief of the Naval Staff but served only briefly until his retirement later that year. (Full article...)
Australia's involvement in the Vietnam War began with a small commitment of 30 military advisors in 1962, and increased over the following decade to a peak of 7,672 Australian personnel following the Menzies Government's April 1965 decision to upgrade its military commitment to South Vietnam's security. By the time the last Australian personnel were withdrawn in 1972, the Vietnam War had become Australia's longest war, eventually being surpassed by Australia's long-term commitment to the War in Afghanistan. It remains Australia's largest force contribution to a foreign conflict since the Second World War, and was also the most controversial military action in Australia since the conscription controversy during World War I. Although initially enjoying broad support due to concerns about the spread of communism in Southeast Asia, an increasingly influential anti-war movement developed, particularly in response to the government's imposition of conscription.
The withdrawal of Australia's forces from South Vietnam began in November 1970, under the Gorton Government, when 8 RAR completed its tour of duty and was not replaced. A phased withdrawal followed and, by 11 January 1973, Australian involvement in hostilities in Vietnam had ceased. Nevertheless, Australian troops from the Australian Embassy Platoon remained deployed in the country until 1 July 1973, and Australian forces were deployed briefly in April 1975, during the fall of Saigon, to evacuate personnel from the Australian embassy. Approximately 60,000 Australians served in the war: 521 were killed and more than 3,000 were wounded. (Full article...)

The 1st Australian Task Force (1 ATF) was a brigade-sized formation which commanded Australian and New Zealand Army units deployed to South Vietnam between 1966 and 1972. 1 ATF was based in a rubber plantation at Nui Dat, 8 kilometres (5.0 mi) north of Bà Rịa in Phuoc Tuy Province and consisted of two and later three infantry battalions, with armour, aviation, engineers and artillery support. While the task force was primarily responsible for securing Phuoc Tuy Province, its units, and the Task Force Headquarters itself, occasionally deployed outside its Tactical Area of Responsibility.
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 Howard government supported the disarmament of Iraq during the Iraq disarmament crisis. Australia later provided one of the four most substantial combat force contingents during the 2003 invasion of Iraq, under the operational codename Operation Falconer. Part of its contingent were among the first forces to enter Iraq after the official "execute" order. The initial Australian force consisted of three Royal Australian Navy ships, a 500-strong special forces task group, two AP-3C Orion maritime patrol aircraft, two B707 Air-to-Air refuelling aircraft, C-130 Hercules transport aircraft and No. 75 Squadron RAAF (which included 14 F/A-18 Hornet fighters). Combat forces committed to Operation Falconer for the 2003 Invasion were withdrawn during 2003. Under the name Operation Catalyst, Australian combat troops were redeployed to Iraq in 2005, however, and assumed responsibility for supporting Iraqi security forces in one of Iraq's southern provinces. These troops began withdrawing from Iraq on 1 June 2008 and were completely withdrawn by 28 July 2009. (Full article...)

HMAS Rankin, sixth submarine of the Collins class, underway in 2006
The Collins-class submarines are Australian-built diesel-electricsubmarines operated by the Royal Australian Navy (RAN). The Collins class takes its name from Australian Vice Admiral John Augustine Collins; each of the six submarines is named after significant RAN personnel who distinguished themselves in action during World War II. The six vessels were the first submarines built in Australia, prompting widespread improvements in Australian industry and delivering a sovereign (Australian controlled) sustainment/maintenance capability.
Planning for a new design to replace the RAN's Oberon-class submarines began in the late 1970s and early 1980s. Proposals were received from seven companies; two were selected for a funded study to determine the winning design, which was announced in mid-1987. The submarines, enlarged versions of Swedish shipbuilder Kockums' Västergötland class and originally referred to as the Type 471, were constructed between 1990 and 2003 in South Australia by the Australian Submarine Corporation (ASC).

Operation Okra was the Australian Defence Force (ADF) contribution to the military intervention against the Islamic State. The deployed forces formed part of Joint Task Force 633 in the Middle East. The operation commenced on 31 August 2014, and its initial stated aim was to combat ISIL threats in Iraq. In September 2015, the Australian airstrikes were extended to Syria. In June 2017, flights in Syria were temporarily halted in response to American forces shooting down a Syrian Air Force jet, before later being resumed.
Operation Okra concluded in December 2024. (Full article...)

The Women's Royal Australian Army Corps (WRAAC) was formed as an all women's corps of the Australian Army in April 1951. Its Colonel-in-Chief was Princess Margaret, Countess of Snowdon. The purpose of the corps was to counter a personnel shortage that developed due to fighting during the Korean War and post-World War II full employment. At the time of its formation, many senior WRAAC personnel had previously served in the Australian Women's Army Service (AWAS), which had been raised during World War II, and as a result the WRAAC is considered to have its origins in the AWAS. The corps consisted of both Regular and part-time personnel, and had commissioned officers, warrant officers, non commissioned officers and other ranks who filled a variety of roles including general duties, cooking, clerical work, instruction, warehousing, and signalling. There were also librarians, coders, projectionists, and psychologists.
Training was completed separately from male recruits at various locations including Queenscliff for soldiers and Georges Heights for officers. Personnel were posted either to formed WRAAC companies, or to male units to fill position vacancies. By the late 1970s female soldiers had begun to be integrated into the Army at large and in late 1984, the WRAAC was disbanded with personnel being transferred to other previously all male corps based on their trade specialty. At this time, female officer cadets began training at the Officer Cadet School, Portsea alongside male cadets, and when Portsea closed down at the end of 1985, they were integrated into the Royal Military College, Duntroon. Female soldiers began training alongside male recruits at the Army Recruit Training Centre at Kapooka in 1985. (Full article...)
The division was demobilised in 1919 before being re-raised in 1921 as part of the Citizen Forces, based in central Victoria. Throughout the 1920s and 1930s, the division's establishment fluctuated due to the effects of the Great Depression and a general apathy towards military matters. (Full article...)

The 2/18th Battalion was an Australian Armyinfantry unit that served during World War II. Formed in June 1940, the battalion was assigned to the 22nd Brigade, which formed part of the Australian 8th Division. After completing basic training, the 2/18th was sent to Singapore and Malaya to strengthen the defences of the British colonies in February 1941 against a possible Japanese attack. The 2/18th Battalion subsequently undertook garrison duties throughout the year at various locations in Malaya, where it conducted jungle training and constructed defences along the eastern coast.
Following the outbreak of war in the Pacific in December 1941, the 2/18th saw action against Japanese forces in the Malayan campaign, during which they took part in a large-scale ambush of a Japanese force on the Malay Peninsula before joining the withdrawal to Singapore in early 1942. Assigned to defend part of the north-west coast of the island, the battalion participated in the unsuccessful defence of Singapore in early February 1942. Following the fall of Singapore the majority of the battalion's personnel were taken as prisoners of war. Many of these men died in captivity; the survivors were liberated in 1945 and returned to Australia where the battalion was disbanded. (Full article...)

The Salamaua platoon of the NGVR on parade in April 1940.
The New Guinea Volunteer Rifles (NGVR) was an infantrybattalion of the Australian Army. It was initially raised as a unit of the Militia from white Australian and European expatriates in New Guinea upon the outbreak of the Second World War in 1939, before being activated for full-time service following the Japanese landings in early 1942. NGVR personnel then helped rescue survivors of Lark Force from Rabaul in February and March 1942. Between March and May, the NGVR monitored the Japanese bases which had been established in the Huon Gulf region, being the only Allied force in the area until the arrival of Kanga Force at Wau in May. The battalion subsequently established observation posts overlooking the main approaches and reported on Japanese movements.
Later, it inflicted significant casualties on the Japanese in a series of raids, and led them to believe that they faced a much larger opposing force. On 29 June, the NGVR and the newly arrived 2/5th Independent Company carried out a highly successful attack on the Japanese garrison in Salamaua, killing at least 113 men. When the focus shifted to the Milne Bay and Kokoda Track battles of August and September, the NGVR continued to man its posts overlooking the Japanese base areas. The Japanese were subsequently defeated in the Battle of Wau in January and February 1943, relieving the pressure on the NGVR. The battalion was disbanded in April 1943 due to attrition.

Isaacson grew up in Melbourne and started working for a newspaper when he was sixteen. He joined the RAAF in 1940. Following his stint in Bomber Command, he became well known in Australia for his tours in the Avro LancasterQ-for-Queenie to promote the sale of war loans and, in particular, for flying his plane under the Sydney Harbour Bridge in 1943. He transferred to the RAAF Reserve after the war, retiring as a wing commander in 1969. From 1956 he served as a Trustee, Chairman, and finally Life Governor of the Victorian Shrine of Remembrance. In 1991 he was appointed a Member of the Order of Australia for his publishing and community work. (Full article...)

The 23rd Battalion was an infantrybattalion of the Australian Army. It was raised in 1915 as part of the Australian Imperial Force for service during World War I and formed part of the 6th Brigade, attached to the 2nd Division. After being formed in Australia, the battalion was sent to Egypt to complete its training, before being committed to the Gallipoli Campaign as reinforcements in September 1915. They remained on the peninsula until the evacuation of Allied troops in December, when they were withdrawn back to Egypt where they were reorganised before being transferred to the Western Front in March 1916. Over the course of the next two-and-a-half years, the 23rd took part in a number of significant battles in France and Belgium, before being disbanded in mid-1919 following the conclusion of hostilities. In 1921, the battalion was re-raised as a part-time unit within the Citizens Forces in the state of Victoria, but was amalgamated with the 21st Battalion in 1929 to form the 23rd/21st Battalion.

Soldiers from the 2/10th prepare for a patrol, Milne Bay, September 1942
The 2/10th Battalion ("The Adelaide Rifles") was an infantrybattalion of the Australian Army that was raised for overseas service as part of the all-volunteer Second Australian Imperial Force (2nd AIF) during World War II. Formed in October 1939, it was the first 2nd AIF unit raised from the state of South Australia during the war; after completing a period of training in Australia, the battalion embarked for overseas service. Initially, it had been intended that the 2/10th and its parent brigade – the 18th Brigade – would be sent to the Middle East to join the other brigades of the 6th Division, but instead the 18th Brigade was sent to strengthen the garrison in the United Kingdom after France capitulated in mid-1940. Reassigned to the 9th Division, the 2/10th remained in the United Kingdom undertaking defensive duties until late 1940 when it finally arrived in the Middle East, where the 18th Brigade became part of the 7th Division.
The battalion's first experience of combat came during an attack against the Italian garrison at Giarabub in March 1941. This was followed by defensive actions during the Siege of Tobruk later in the year before the 2/10th joined the Allied garrison in Syria, which had previously been captured from the Vichy French. In early 1942, following Japan's entry into the war, the 2/10th was withdrawn to Australia and in August 1942, at the height of the Japanese advance in the Pacific, the battalion was committed to the fighting around Milne Bay in the Territory of Papua, suffering heavy casualties in their debut in the Pacific. Further fighting came during the Battle of Buna–Gona in northern Papua before the 2/10th was brought back to Australia for re-organisation in March 1943. In August 1943, it was sent to the Territory of New Guinea, first undertaking jungle training near Port Moresby and then, in December 1943, moving inland into the Finisterre Mountains where they later fought the Battle of Shaggy Ridge. After being withdrawn to Australia in mid-1944, the battalion did not take part in further fighting until the final months of the war when they were committed to the fighting on Balikpapan in July 1945. Following the conclusion of hostilities, the 2/10th Battalion was disbanded in December 1945. (Full article...)

No. 8 Service Flying Training School (No. 8 SFTS) was a flying training school of the Royal Australian Air Force (RAAF) that operated during World War II. It was formed in December 1941, and graduated its first course in March 1942. Responsible for intermediate and advanced instruction of pilots under the Empire Air Training Scheme (EATS), the school was based at RAAF Station Bundaberg, Queensland, and operated Avro Anson aircraft. It spawned two maritime patrol squadrons in early 1943, raised in response to increased Japanese submarine activity off Australia's east coast. Some of the school's aircraft were also attached to the Australian Army in 1944–45. No. 8 SFTS completed its final training course in December 1944, and was disbanded in July 1945. (Full article...)

HMAS Australia (III) was a County classheavy cruiser operated by the Royal Australian Navy. Australia was laid down on August 26, 1925, launched on March 17, 1927 and commissioned on April 24, 1928. HMAS Australia was one of the RAN's few major units during the 1930s and saw active service around the world during World War II. Australia first saw action off Dakar in September 1940 and escorted convoys and patrolled the Atlantic and Indian Oceans during 1941. Following the onset of the Pacific War, Australia was re-deployed to the South West Pacific Area where she took part on the Battle of the Coral Sea. From August 1942 until mid-1944 Australia provided supporting fire and surface protection for Allied land forces. HMAS Australia was damaged by the first-ever kamikaze attack while operating off the Philippines on October 21, 1944. While Australia returned to service in January 1945 she was hit by further kamikazes and was under repair at the end of the war. Following the end of the war, Australia served as a training ship until she was paid off for disposal on August 31, 1954.
"Australian troops had, at Milne Bay, inflicted on the Japanese their first undoubted defeat on land. Some of us may forget that, of all the allies, it was the Australians who first broke the invincibility of the Japanese army."
