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 Aboriginals 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...)
Roy Cecil Phillipps, MC& Bar, DFC (1 March 1892 – 21 May 1941) was an Australian fighter ace of World War I. He achieved fifteen victories in aerial combat, four of them in a single action on 12 June 1918. A grazier between the wars, he joined the Royal Australian Air Force (RAAF) in 1940 and was killed in a plane crash the following year.
The Battle of Arras (also known as the Second Battle of Arras) was a British offensive on the Western Front during the First World War. From 9 April to 16 May 1917, British troops attacked German defences near the French city of Arras on the Western Front. The British achieved the longest advance since trench warfare had begun, surpassing the record set by the French Sixth Army on 1 July 1916. The British advance slowed in the next few days and the German defence recovered. The battle became a costly stalemate for both sides and by the end of the battle, the British Third Army and the First Army had suffered about 160,000 casualties and the German 6th Army about 125,000.
For much of the war, the opposing armies on the Western Front were at stalemate, with a continuous line of trenches from the Belgian coast to the Swiss border. The Allied objective from early 1915 was to break through the German defences into the open ground beyond and engage the numerically inferior German Army (Westheer) in a war of movement. The British attack at Arras was part of the Anglo-French Nivelle Offensive, the main part of which was the Second Battle of the Aisne 50 mi (80 km) to the south. The aim of the French offensive was to break through the German defences in forty-eight hours. At Arras the Canadians were to capture Vimy Ridge, dominating the Douai Plain to the east, advance towards Cambrai and divert German reserves from the French front. (Full article...)

Australian soldiers from the 2/16th Battalion arriving at Kaiapit on 20 September after the area was captured by the 2/6th Independent Company
The Australian 2/6th Independent Company flew in to the Markham Valley from Port Moresby in 13 USAAFC-47 Dakotas, making a difficult landing on a rough airstrip. Unaware that a much larger Japanese force was also headed for Kaiapit, the company attacked the village on 19 September to secure the area so that it could be developed into an airfield. The company then held it against a strong counter-attack. During two days of fighting the Australians defeated a larger Japanese force while suffering relatively few losses. (Full article...)
Information is scarce about the basic facts of the massacre, including the exact date and number of victims. A contemporary account of the massacre listed nine victims – three women, two teenage girls, three infants, and an "old man blind and infirm". Another account published by Christina Smith in 1880 gave the number of victims as eleven, and specified that they belonged to the Tanganekald people. Pastoralist James Brown and his overseer, a man named Eastwood, were suspected of committing the murders in retaliation for attacks on Brown's sheep. (Full article...)

The Avro Ansons after landing safely, having collided in mid-air and locked together, 29 September 1940
On 29 September 1940, a mid-air collision occurred over Brocklesby, New South Wales, Australia. The accident was unusual in that the aircraft involved, two Royal Australian Air Force (RAAF) Avro Ansons of No. 2 Service Flying Training School, remained locked together after colliding, and then landed safely. The collision stopped the engines of the upper Anson, but those of the one underneath continued to run, allowing the aircraft to keep flying. Both navigators and the pilot of the lower Anson bailed out. The pilot of the upper Anson found that he was able to control the interlocked aircraft with his ailerons and flaps, and made an emergency landing in a nearby paddock. All four crewmen survived the incident. The upper Anson was repaired and returned to flight service; the lower Anson was used as an instructional airframe. (Full article...)

Denny in c. 1910
William Joseph DennyMC (6 December 1872 – 2 May 1946) was an Australian journalist, lawyer, politician and decorated soldier who held the South Australian House of Assembly seats of West Adelaide from 1900 to 1902 and then Adelaide from 1902 to 1905 and again from 1906 to 1933. After an unsuccessful candidacy as a United Labor Party (ULP) member in 1899, he was elected as an "independent liberal" in a by-election in 1900. He was re-elected in 1902, but defeated in 1905. The following year, he was elected as a ULP candidate, and retained his seat for that party (the Australian Labor Party from 1917) until 1931. Along with the rest of the cabinet, he was ejected from the Australian Labor Party in 1931, and was a member of the Parliamentary Labor Party until his electoral defeat at the hands of a Lang Labor Party candidate in 1933.
Leak was evacuated to the United Kingdom, and did not return to his unit until October 1917. Suffering from the effects of his service, Leak was convicted of desertion by a court-martial in November, but his sentence was ultimately suspended, and he returned to the 9th Battalion. In early March 1918 he was gassed, and did not rejoin to his unit until the Armistice of 11 November 1918. He returned to Australia and was discharged in 1919. (Full article...)

Area commands were the major operational and administrative formations of the Royal Australian Air Force (RAAF) between 1940 and 1954. Established in response to the outbreak of World War II, they underpinned the Air Force's geographically based command-and-control system for the duration of the conflict and into the early years of the Cold War, until being superseded by a functional control system made up of Home, Training, and Maintenance Commands.
The area commands and their responsibilities evolved over time according to changing circumstances. The RAAF established four commands to begin with in 1940–41: Southern Area, Central Area, Western Area, and Northern Area. They oversaw most of the operations, training and maintenance within their boundaries. A concession to functional control occurred in mid-1941, when the Air Force formed two groups that assumed the training role of the southern and eastern states; Central Area was disbanded and most of its units taken over by Northern and Southern Areas, and the newly formed No. 2 (Training) Group. The area structure was further revised in 1942, following the outbreak of the Pacific War; Northern Area was split into North-Eastern Area and North-Western Area, and a new command, Eastern Area, was created, making a total of five commands. The same year, the RAAF formed two functional groups that assumed the maintenance role of the area commands; the latter focussed on operations until the end of hostilities. A new area command covering RAAF units in New Guinea, Northern Command, was formed in 1944 and dissolved soon after the war. (Full article...)
The Rivers saw service during World War I. Ships of the class participated in the Australian Naval and Military Expeditionary Force capture of German New Guinea, and performed patrols in Australian and Malayan waters. In 1917, the class was deployed as a single unit to the Mediterranean, and assigned to anti-submarine patrols of the Adriatic. The destroyers returned to Australia in 1919, and were placed in reserve. (Full article...)
The Ikaramissile was an Australian ship-launched anti-submarine missile, named after an Australian Aboriginal word for "throwing stick". It launched an acoustic torpedo to a range of 10 nautical miles (19 km), allowing fast-reaction attacks against submarines at ranges that would otherwise require the launching ship to close for attack, placing itself at risk. By flying to a distant target, the engagement time was dramatically shorter than provided by short-range weapons, giving the target less time to respond. (Full article...)

The Inspector-General of the Australian Defence Force Afghanistan Inquiry Report, commonly known as the Brereton Report (after the investigation head), is a report into war crimes committed by the Australian Defence Force (ADF) during the War in Afghanistan between 2005 and 2016. The investigation was led by Paul Brereton, who is both a New South Wales Supreme Court judge and a major general in the army reserve. The independent commission was initiated by the Inspector-General of the Australian Defence Force in 2016, and after a long investigation, delivered its final report on 6 November 2020. The redacted version was released publicly on 19 November 2020.
The report found evidence of 39 murders of civilians and prisoners by (or at the instruction of) members of the Australian special forces, which were subsequently covered up by ADF personnel. The report stated 25 ADF personnel were involved in the killings, including those who were "accessories" to the incident. Some of those believed to be involved were still serving with the ADF. The unlawful killings discussed by the report began in 2009, with most occurring in 2012 and 2013. (Full article...)
The Rum Rebellion of 1808 was a coup d'état in the then-British penal colony of New South Wales, staged by the New South Wales Corps in order to depose GovernorWilliam Bligh. Australia's first and only military coup, its name derives from the illicit rum trade of early Sydney, over which the 'Rum Corps', as it became known, maintained a monopoly. During the first half of the 19th century, it was widely referred to in Australia as the Great Rebellion.
Bligh, a former Royal Navy captain known for his overthrow in the mutiny on the Bounty, had been appointed governor in 1805 to rein in the power of the Corps. Over the next two years, Bligh made enemies not only of Sydney's military elite, but several prominent civilians, notably John Macarthur, who joined MajorGeorge Johnston in organising an armed takeover. On 26 January 1808, 400 soldiers marched on Government House and arrested Bligh. He was kept in confinement in Sydney, then aboard a ship off Hobart, Van Diemen's Land, for the next two years while Johnston acted as Lieutenant-Governor of New South Wales. The military remained in control until the 1810 arrival from Britain of Major-GeneralLachlan Macquarie, who took over as governor. (Full article...)
Operation Okra is the Australian Defence Force (ADF) contribution to the military intervention against the Islamic State. The force is 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. (Full article...)

In 1911, at the Imperial Conference held in London, it was decided that aviation should be developed by the national armed forces of the British Empire. Australia became the first member of the Empire to follow this policy. By the end of 1911, the Army was advertising for pilots and mechanics. During 1912, pilots and mechanics were appointed, aircraft were ordered, the site of a flying school was chosen and the first squadron was officially raised. On 7 March 1913, the government officially announced formation of the Central Flying School (CFS) and an "Australian Aviation Corps", although that name was never widely used. (Full article...)

The Indonesia–Malaysia confrontation (Indonesian: Konfrontasi) was fought from 1962 to 1966 between the British Commonwealth and Indonesia. Indonesia, under President Sukarno, sought to prevent the creation of the new Federation of Malaysia that emerged in 1963, whilst the British Commonwealth sought to safeguard the security of the new state. The war remained a limited one however, and was fought primarily on the island of Borneo, although a number of Indonesian seaborne and airborne incursions into the Malay Peninsula did occur. As part of Australia's continuing military commitment to the security of Malaysia, Australian army, naval and air force units were based there with the Far East Strategic Reserve, mainly in the 28th Commonwealth Infantry Brigade Group.
The Australian Government was initially reluctant to become involved in the conflict, and Australian forces did not see combat until 1964. Australia's involvement expanded in 1965, however, following repeated requests from the British Government with an Australian infantry battalion and special forces being deployed to Borneo where they were involved in a number of actions against Indonesian Army units. Other army units deployed included artillery batteries and engineers, both of which served tours in support of the infantry in Borneo. A number of RAN warships also patrolled the waters off Borneo and Malaysia to deter Indonesian infiltration parties, and were involved in shelling Indonesian positions in Borneo and in repelling infiltrators in the Singapore Strait. The RAAF played only a relatively minor role, although it would have been used far more extensively had the war escalated. (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...)
Japan's geography made this invasion plan obvious to the Japanese as well; they were able to accurately predict the Allied invasion plans and thus adjust their defensive plan, Operation Ketsugō (ja), accordingly. The Japanese planned an all-out defense of Kyūshū, with little left in reserve for any subsequent defense operations. Casualty predictions varied widely, but were extremely high. Depending on the degree to which Japanese civilians would have resisted the invasion, estimates ran up into the millions for casualties. (Full article...)

The above map shows how the network of fortresses defended the approaches to Hobart. The shaded white areas show the effective range of the fort's gun positions.
The Hobart coastal defences are a network of now defunct coastal batteries, some of which are inter-linked with tunnels, that were designed and built by British colonial authorities in the nineteenth century to protect the city of Hobart, Tasmania, from attack by enemy warships. During the nineteenth century, the port of Hobart Town was a vital re-supply stop for international shipping and trade, and therefore a major freight hub for the British Empire. As such, it was considered vital that the colony be protected. In all, between 1804 and 1942 there were 12 permanent defensive positions constructed in the Hobart region.
Prior to Australian Federation, the island of Tasmania was a colony of the British Empire, and as such was often at war with Britain's enemies and European rivals, such as France and later Russia. The British had already established the colony of Sydney at Port Jackson in New South Wales in 1788, but soon began to consider the island of Tasmania as the potential site of a useful second colony. It was an island, cut off from the mainland of Australia and isolated geographically, making it ideal for a penal colony, and was rich in timber, a resource useful to the Royal Navy. In 1803, the British authorities decided to colonise Tasmania, and to establish a permanent settlement on the island that was at the time known as Van Diemen's Land, primarily to prevent the French from doing so. During this period tensions between Great Britain and France remained high. The two nations had been fighting the French Revolutionary Wars with each other through much of the 1790s, and would soon be engaging each other again in the Napoleonic Wars. (Full article...)

American manned Alligators during the landing of Australian troops at Balikpapan, Borneo
The Battle of Balikpapan was the concluding stage of Operation Oboe, the campaign to liberate Japanese-held British and Dutch Borneo. The landings took place on 1 July 1945. The Australian 7th Division, composed of the 18th, 21st and 25th Infantry Brigades, with a small number of Netherlands East Indies KNIL troops, made an amphibious landing, codenamed Operation Oboe Two, a few miles north of Balikpapan. The Allied invasion fleet consisted of around 100 ships. The landing had been preceded by heavy bombing and shelling by Australian and US air and naval forces. The Allied force totalled 33,000 personnel and was commanded by Major General Edward Milford, while the Japanese force, commanded by Rear Admiral Michiaki Kamada, numbered between 8,400 and 10,000, of which between 3,100 and 3,900 were combatants. After the initial landing, the Allies secured the town and its port, and then advanced along the coast and into the hinterland, capturing the two Japanese airfields. Major combat operations concluded around 21 July, but were followed by mopping-up operations, which lasted until the end of the war in mid-August. Australian troops remained in the area until early 1946. (Full article...)
The fighting occurred following a failed landing by Australian forces at Porton Plantation in early June, which was part of an attempt to outflank a series of strong points that the Japanese had built across the base of the Bonis Peninsula. After this, the fighting in the northern sector around Ratsua essentially became a containment action for the Australians as they concentrated their efforts and resources upon driving south towards Buin, which was the main centre of Japanese resistance on the island at the time. As a result, the situation around Ratsua remained largely static until the end of hostilities in mid-August 1945. (Full article...)

The Battle of France (French: bataille de France; 10 May – 25 June 1940), also known as the Western Campaign (German: Westfeldzug), the French Campaign (Frankreichfeldzug, campagne de France) and the Fall of France, during the Second World War was the German invasion of France, that notably introduced tactics that are still used. France and the Low Countries were conquered, ending land operations on the Western Front until the Normandy landings on 6 June 1944.
Sir Wilfrid Selwyn "Bill" Kent Hughes, KBE,MVO,MC (12 June 1895 – 31 July 1970) was an Australian army officer and politician who had a long career in both state and federal politics, most notably as a minister in the Menzies government. He also had a longstanding involvement with the Olympic movement, as both an athlete and organiser.
The wing was established to provide fighter protection for an Allied offensive from Darwin in northern Australia into the eastern Netherlands East Indies (NEI). This operation was effectively cancelled in June 1944, however, leaving No. 80 Wing without a clear mission. The unit remained at Darwin until it moved to Morotai in the NEI between December 1944 and March 1945. Due to the small number of Japanese aircraft remaining in this area the Wing's aircraft were mainly used in the ground attack role. From May 1945 to the end of the war two of No. 80 Wing's squadrons participated in the Borneo Campaign. (Full article...)
