General Sir Henry George Chauvel, GCMG, KCB (16 April 1865 – 4 March 1945) was a senior officer of the Australian Imperial Force who fought at Gallipoli and during the Sinai and Palestine Campaign in the Middle Eastern theatre of World War I. He was the first Australian to attain the rank of lieutenant general and later general, and the first to lead a corps. As commander of the Desert Mounted Corps, he was responsible for one of the most decisive victories and fastest pursuits in military history.

The son of a grazier, Chauvel was commissioned as a second lieutenant in the Upper Clarence Light Horse, a unit organised by his father, in 1886. After the family moved to Queensland he was commissioned as a second lieutenant in the Queensland Mounted Infantry in 1890, and saw service during the 1891 Australian shearers' strike. He became a regular officer in 1896, and went to the United Kingdom as part of the Queensland contingent for the 1897 Diamond Jubilee of Queen Victoria. In 1899 he commanded one of two companies of Queensland Mounted Infantry that were Queensland's initial contribution to the Boer War. After the war, he was closely involved with the training of the Australian Light Horse. (Full article...)

Peter Jeffrey, DSO, DFC (6 July 1913 – 6 April 1997) was a senior officer and fighter ace in the Royal Australian Air Force (RAAF). Born in Tenterfield, New South Wales, he joined the RAAF active reserve in 1934, and transferred to the Permanent Air Force (PAF) shortly before World War II. Posted to the Middle East in July 1940, Jeffrey saw action with No. 3 Squadron and took command of the unit the following year, earning the Distinguished Flying Cross for his energy and fighting skills. He was appointed wing leader of No. 234 Wing RAF in November 1941, and became an ace the same month with his fifth solo victory. The next month he was awarded the Distinguished Service Order for his achievements, which included rescuing a fellow pilot who had crash landed in the desert.

In 1942, Jeffrey was posted to the South West Pacific, where he helped organise No. 75 Squadron for the defence of Port Moresby, and No. 76 Squadron before the Battle of Milne Bay. He served two stints in charge of No. 2 Operational Training Unit in southern Australia before the end of the war, broken by command of No. 1 (Fighter) Wing in the Northern Territory and Western Australia during 1943–44, at which time he was promoted to temporary group captain. Jeffrey was transferred to the RAAF reserve after the war but returned to the PAF in 1951, holding training posts in Victoria and command of RAAF Base Edinburgh in South Australia, before resigning in 1956. Outside the military, he was a grazier and stockbroker. He died in 1997 at the age of 83. (Full article...)

The Australian Air Corps (AAC) was a temporary formation of the Australian military that existed in the period between the disbandment of the Australian Flying Corps (AFC) of World War I and the establishment of the Royal Australian Air Force (RAAF) in March 1921. Raised in January 1920, the AAC was commanded by Major William Anderson, a former AFC pilot. Many of the AAC's members were also from the AFC and would go on to join the RAAF. Although part of the Australian Army, for most of its existence the AAC was overseen by a board of senior officers that included members of the Royal Australian Navy.

Following the disbandment of the AFC, the AAC was a stop-gap measure intended to remain in place until the formation of a permanent and independent Australian air force. The corps' primary purpose was to maintain assets of the Central Flying School at Point Cook, Victoria, but several pioneering activities also took place under its auspices: AAC personnel set an Australian altitude record that stood for a decade, made the first non-stop flight between Sydney and Melbourne, and undertook the country's initial steps in the field of aviation medicine. The AAC operated fighters, bombers and training aircraft, including some of the first examples of Britain's Imperial Gift to arrive in Australia. As well as personnel, the RAAF inherited Point Cook and most of its initial equipment from the AAC. (Full article...)

James Park Woods VC (4 January 1886 – 18 January 1963) was an Australian recipient of the Victoria Cross during World War I; the Victoria Cross was the highest award for gallantry in the face of the enemy that could be awarded to members of the Australian armed forces at the time. Woods enlisted in the Australian Imperial Force in September 1916 and, after training in Australia and the United Kingdom, joined his unit, the 48th Battalion, in France in September 1917. Along with the rest of his battalion, he participated in the First Battle of Passchendaele the following month. In early 1918, Woods was hospitalised for several months before rejoining his unit in May. He again reported sick in July, and did not return to the 48th Battalion until mid-August.

On 18 September 1918, the 48th Battalion was involved in the attack on the Hindenburg Outpost Line during the Hundred Days Offensive. After the first phase of the attack, some elements of Woods' unit were tasked to support another battalion as it conducted a further assault. When it was suspected that flanking British troops had not gone forward to their objective as reported, a four-man patrol including Woods attempted to make contact with them. Instead of finding British troops, they encountered a strong German post and, after calling for reinforcements, attacked it, driving more than thirty Germans from the position. Woods' actions during this assault and subsequent defence of the captured post resulted in him being awarded the Victoria Cross. Woods survived the war, returned to Australia and operated a vineyard and orchard in Western Australia. He retired early due to ill health and died in 1963. His medals are displayed in the Hall of Valour at the Australian War Memorial. (Full article...)

Australian Hospital Ship (AHS) Centaur was a hospital ship which was attacked and sunk by a Japanese submarine off the coast of Queensland, Australia, on 14 May 1943. Of the 332 medical personnel and civilian crew aboard, 268 died, including 63 of the 65 army personnel.

The Scottish-built vessel was launched in 1924 as a combination passenger liner and refrigerated cargo ship and operated a trade route between Western Australia and Singapore via the Dutch East Indies (now Indonesia), carrying passengers, cargo, and livestock. At the start of World War II, Centaur (like all British Merchant Navy vessels) was placed under British Admiralty control, but after being fitted with defensive equipment, was allowed to continue normal operations. In November 1941, the ship rescued German survivors of the engagement between Kormoran and HMAS Sydney. Centaur was relocated to Australia's east coast in October 1942, and used to transport materiel to New Guinea. (Full article...)

Richard Cresswell, DFC (27 July 1920 – 12 December 2006) was an officer and pilot in the Royal Australian Air Force (RAAF). He held command of No. 77 (Fighter) Squadron twice during World War II, and again during the Korean War. Cresswell was credited with being the first RAAF pilot to shoot down an enemy aircraft at night over Australian soil, the only man to serve as commanding officer of an RAAF squadron on three occasions during wartime, and the first officer to lead a jet-equipped Australian squadron in combat. His performance in Korea earned him both the Commonwealth and the US Distinguished Flying Crosses.

Born in Tasmania, Cresswell worked as an apprentice electrician before joining the RAAF in July 1938. He initially commanded No. 77 Squadron from April 1942 to August 1943, flying P-40 Kittyhawks in defence of Australia's North-Western Area against Japanese raiders. Cresswell claimed the squadron's first aerial victory—the first by an Australian over the mainland—in November 1942. He was wing leader of No. 81 (Fighter) Wing in New Guinea from May 1944 to March 1945, simultaneously commanding No. 77 Squadron for a second time between September and December 1944. In September 1950, during the Korean War, Cresswell took command of No. 77 Squadron in combat for the third time. He oversaw its conversion from P-51 Mustangs to Gloster Meteors, becoming the first RAAF commander of a jet squadron in war. As well as Meteors, Cresswell flew F-80 Shooting Star and F-86 Sabre jets in combat while on attachment to the United States Air Force in Korea. He handed over command of No. 77 Squadron for the last time in August 1951, but flew six more missions as a Meteor pilot in 1953. (Full article...)

Alexander Augustus Norman Dudley "Jerry" Pentland, MC, DFC, AFC (5 August 1894 – 3 November 1983) was an Australian fighter ace in World War I. Born in Maitland, New South Wales, he commenced service as a Lighthorseman with the Australian Imperial Force in 1915, and saw action at Gallipoli. He transferred to the Royal Flying Corps the following year, rising to captain. Credited with twenty-three aerial victories, Pentland became the fifth highest-scoring Australian ace of the war, after Robert Little, Stan Dallas, Harry Cobby and Roy King. He was awarded the Military Cross in January 1918 for "conspicuous gallantry and devotion to duty" on a mission attacking an aerodrome behind enemy lines, and the Distinguished Flying Cross that August for engaging four hostile aircraft single-handedly.

Pentland served in the fledgling Royal Australian Air Force (RAAF), and later the Royal Air Force, before going into business in 1927. His ventures included commercial flying around the goldfields of New Guinea, aircraft design and manufacture, flight instruction, and charter work. In the early 1930s, he was employed as a pilot with Australian National Airways, and also spent time as a dairy farmer. Soon after the outbreak of World War II, he re-enlisted in the RAAF, attaining the rank of squadron leader and commanding rescue and communications units in the South West Pacific. Perhaps the oldest operational pilot in the wartime RAAF, Pentland was responsible for rescuing airmen, soldiers and civilians, and earned the Air Force Cross for his "outstanding courage, initiative and skill". He became a trader in New Guinea when the war ended in 1945, and later a coffee planter. Retiring in 1959, he died in 1983 at the age of eighty-nine. (Full article...)

Air Vice Marshal Stanley James (Jimmy) Goble, CBE, DSO, DSC (21 August 1891 – 24 July 1948) was a senior commander in the Royal Australian Air Force (RAAF). He served three terms as Chief of the Air Staff, alternating with Wing Commander (later Air Marshal Sir) Richard Williams. Goble came to national attention in 1924 when he and fellow RAAF pilot Ivor McIntyre became the first men to circumnavigate Australia by air, journeying 8,450 miles (13,600 km) in a single-engined floatplane.

During World War I, Goble flew fighters on the Western Front with the British Royal Naval Air Service. He became an ace with ten victories, commanded No. 5 Squadron (later No. 205 Squadron RAF), and was awarded the Distinguished Service Order and the Distinguished Service Cross. Returning to Australia, Goble assisted in the formation of the RAAF as an independent branch of the Australian armed forces. On an exchange posting to Britain in the 1930s, he led No. 2 (Bomber) Group RAF. (Full article...)

John Woods Whittle, VC, DCM (3 August 1882 – 2 March 1946) was an Australian recipient of the Victoria Cross, the highest decoration for gallantry "in the face of the enemy" that can be awarded to members of the British and British Commonwealth armed forces. Whittle was serving as a sergeant in the First World War when he was decorated with the Victoria Cross following two separate actions against German forces during their retreat to the Hindenburg Line in 1917. In the latter action, he attacked a machine gun crew, killing the group and seizing the gun.

Born in Tasmania, Whittle completed twelve months active service during the Second Boer War, before returning to Australia and enlisting in the Royal Navy, where he served for five years as a stoker. Re-enlisting in the army, he was posted to the Army Service Corps, artillery, and Tasmanian Rifle Regiment before the outbreak of the First World War. Transferring to the Australian Imperial Force in 1915, Whittle joined the 12th Battalion in Egypt and embarked for the Western Front the following year. During an attack on the village of La Barque, Whittle rushed a German trench and forced the men from the position; he was awarded the Distinguished Conduct Medal as a result. (Full article...)

The invasion of Tulagi, on 3–4 May 1942, was part of Operation Mo, the Empire of Japan's strategy in the South Pacific and South West Pacific Area in 1942. The plan called for Imperial Japanese Navy troops to capture Tulagi and nearby islands in the British Solomon Islands Protectorate. The occupation of Tulagi by the Japanese was intended to cover the flank of and provide reconnaissance support for Japanese forces that were advancing on Port Moresby in New Guinea, provide greater defensive depth for the major Japanese base at Rabaul, and serve as a base for Japanese forces to threaten and interdict the supply and communication routes between the United States and Australia and New Zealand.

Without the means to effectively resist the Japanese offensive in the Solomons, the British Resident Commissioner of the Solomon Islands protectorate and the few Australian troops assigned to defend Tulagi evacuated the island just before the Japanese forces arrived on 3 May. The next day, however, a U.S. aircraft carrier task force en route to resist the Japanese forces advancing on Port Moresby (later taking part in the Battle of the Coral Sea) struck the Japanese Tulagi landing force in an air attack, destroying or damaging several of the Japanese ships and aircraft involved in the landing operation. Nevertheless, the Japanese troops successfully occupied Tulagi and began the construction of a small naval base. (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.

Significant battles conducted by the Task Force were Battle of Long Tan in 1966, Battle of Suoi Chau Pha in 1967, and Operation Coburg and the Battle of Coral–Balmoral in 1968. Other significant actions included Battle of Hat Dich in late-December 1968 and early 1969, Battle of Binh Ba in June 1969, and Battle of Long Khanh in June 1971. (Full article...)

Fort Lytton National Park is a national park in Lytton, City of Brisbane, Queensland, Australia. Its main attraction is Fort Lytton Historic Military Precinct, providing guided tours of historic Fort Lytton, a museum and re-enactments. The park was created in 1990 as Queensland's first historic national park. It initially contained only heritage-listed Fort Lytton, a colonial coastal fort that continued to operate as a military base until after the Second World War. The park was extended in 1999 to include Lytton Quarantine Station which occupied adjacent land. The Quarantine Station is also heritage-listed, but is only open to the public on special occasions.

The park is 13 kilometres (8.1 mi) northeast of the Brisbane CBD near the mouth of the Brisbane River. (Full article...)

The Surafend massacre (Arabic: مجزرة صرفند) was a premeditated massacre committed against inhabitants of the village of Sarafand al-Amar (modern-day Tzrifin) and a Bedouin camp in Ottoman Palestine by occupying Australian, New Zealand and Scottish soldiers on 10 December 1918. Occurring at the conclusion of the Sinai and Palestine campaign of World War I, Allied occupational forces in the region, in particular Australian and New Zealand troops, gradually grew frustrated over being subject to petty theft and occasional murders by local Arabs without redress.

On the night of 9 December, a New Zealand soldier was killed by an Arab thief who had stolen his kitbag. In response, troops of the ANZAC Mounted Division, as well as a small number of Scottish soldiers, surrounded Sarafand al-Amar and demanded the village's leaders hand over the thief. When they denied knowledge of the murder, the soldiers deliberated on their course of action before eventually deciding to attack the village, killing approximately 40–137 male villagers, with the only body count being 137 while others who did not count the bodies stated it was as low as 40. The massacre caused a significant rift between the Division and its Commander-in-Chief, Sir Edmund Allenby. (Full article...)

The Invasion of Lingayen Gulf (Filipino: Paglusob sa Golpo ng Lingayen), 3–13 January 1945, was an Allied amphibious operation in the Philippines during World War II. In the early morning of 6 January 1945, a large Allied force commanded by Admiral Jesse B. Oldendorf began approaching the shores of Lingayen from Lingayen Gulf, on the island of Luzon. U.S. Navy and Royal Australian Navy warships began bombarding suspected Japanese positions along the coast of Lingayen from their position in Lingayen Gulf for three days. On "S-Day", 9 January, the U.S. 6th Army landed on a roughly 25 mi (40 km) beachhead at the base of the Gulf between the towns of Lingayen and San Fabian. (Full article...)

Clive Robertson Caldwell, DSO, DFC & Bar (28 July 1911 – 5 August 1994) was the leading Australian air ace of World War II. He is officially credited with shooting down 28.5 enemy aircraft in over 300 operational sorties, including an ace in a day. In addition to his official score, he has been ascribed six probables and 15 damaged. Caldwell flew Curtiss P-40 Tomahawks and Kittyhawks in the North African Campaign and Supermarine Spitfires in the South West Pacific Theatre. He was the highest-scoring P-40 pilot from any air force and the highest-scoring Allied pilot in North Africa. Caldwell also commanded a Royal Air Force (RAF) squadron and two Royal Australian Air Force (RAAF) wings. His military service ended in controversy, when he resigned in protest at the misuse of Australian First Tactical Air Force's fighter units and was later court martialed and convicted for trading liquor.

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 AC1 Sentinel was a cruiser tank designed in Australia in World War II in response to the war in Europe, and to the threat of Japan expanding the war to the Pacific or even a feared Japanese invasion of Australia. It was the first tank to be built with a hull cast as a single piece, and the only tank to be produced in quantity in Australia. The few Sentinels that were built never saw action as Australia's armoured divisions had been equipped by that time with British and American tanks. (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...)

General Sir Francis George Hassett, AC, KBE, CB, DSO, LVO (11 April 1918 – 11 June 2008) was an Australian general who rose to the position of Chief of the Defence Force Staff, the professional head of the Australian Defence Force, serving in this capacity from November 1975 until April 1977. Hassett joined the Australian Army in 1935 upon gaining entrance into the Royal Military College, Duntroon. Serving with distinction in the early stages of the Second World War, he was promoted to lieutenant colonel in 1942 at the age of 23, and posted as a staff officer for the remainder of the war.

In 1951, Hassett was appointed to command the 3rd Battalion, Royal Australian Regiment in Korea, where he led the unit through some of the toughest fighting of the war. For his leadership and planning during the Battle of Maryang San, he was granted an immediate award of the Distinguished Service Order. Promoted to brigadier in 1960, Hassett commanded a brigade in Malaya for three years, before returning to Australia and serving in a variety of positions, culminating in his appointment as Chief of the General Staff with the rank of lieutenant general. Promoted to general after two years in this role, he was appointed Chairman, Chiefs of Staff Committee, which was reorganised as Chief of the Defence Force Staff the following year. Hassett died in 2008 at the age of 90. (Full article...)

Charles Curnow Scherf, DSO, DFC & Bar (17 May 1917 – 13 July 1949) was an Australian flying ace of the Second World War. Born in New South Wales, Scherf was working on his father's grazing property when he enlisted in the Royal Australian Air Force in 1941. On graduating as a pilot, he was sent to the United Kingdom for service in the European theatre. Flying de Havilland Mosquitos with No. 418 Squadron RCAF, Scherf was credited with the destruction of 7½ aircraft in the air and on the ground, and awarded the Distinguished Flying Cross. Afterward, he was posted for duties with Headquarters Air Defence of Great Britain. He nevertheless returned occasionally to No. 418 Squadron and flew operational sorties with the unit, destroying a further 16 aircraft and earning two more decorations. By the end of the war, Scherf had achieved 14½ aerial victories in 38 operational sorties. He was also credited with destroying nine aircraft on the ground, and with damaging seven others.

The General Dynamics F-111C (nicknamed the "Pig") is a variant of the F-111 Aardvark medium-range interdictor and tactical strike aircraft, developed by General Dynamics to meet Australian requirements. The design was based on the F-111A model but included longer wings and strengthened undercarriage. The Australian government ordered 24 F-111Cs to equip the Royal Australian Air Force (RAAF) in 1963, but the aircraft were not delivered until 1973 because of long-running technical problems. During 1979 and 1980 four of these aircraft were converted to the RF-111C reconnaissance variant. Four ex–United States Air Force (USAF) F-111As were purchased by Australia and converted to F-111C standard in 1982 to replace F-111Cs destroyed during accidents. Australia also operated 15 F-111Gs between 1993 and 2007, mainly for conversion training. The RAAF retired its remaining F-111Cs in December 2010. In Australian military and aviation circles, the F-111 Aardvark was affectionately known as the "Pig", due to its long snout and terrain-following ability.

The F-111Cs gave the RAAF a powerful strike capability but were never used in combat. The aircraft went through modernization programs in the 1980s and 1990s, and the RAAF acquired improved weapons to maintain their ability to penetrate hostile airspace. Despite this, by the 2000s the F-111Cs were becoming outdated and expensive to maintain, leading to a decision to retire them in 2010 rather than 2020 as originally planned. The F-111s were replaced by 24 Boeing F/A-18F Super Hornets pending delivery of F-35 Lightning IIs in development. (Full article...)

The 7th Battalion was an infantry battalion of the Australian Army. Raised in 1914 as part of the Australian Imperial Force during the First World War, the battalion was completely recruited from the state of Victoria and formed the 2nd Brigade, 1st Division. The battalion served during the Gallipoli campaign where it had the distinction of having four of its members awarded the Victoria Cross. In 1916, it was transferred to Europe, fighting in the trenches along the Western Front for the next two and a half years.

Although disbanded in 1919 following the end of hostilities, it was re-raised in 1921 in the Citizens Force (later known as the Militia) as a part-time infantry battalion based in Victoria. However, due to lack of funding following the Great Depression and a shortage of manpower following the suspension of the compulsory training scheme in 1929, the battalion was amalgamated with the 38th Battalion as the 7th/38th Battalion, although it was delinked again in 1936 when the Army was expanded due to rising tensions in Europe.

The Battle of Suối Châu Pha (6 August 1967) was fought during the Vietnam War between Australian troops and the Việt Cộng. The battle took place during Operation Ballarat, an Australian search and destroy operation in the eastern Hát Dịch area, north-west of Núi Đất in Phước Tuy province. Following a covert insertion the day before which had caught a number of Việt Cộng sentries by surprise, A Company, 7th Battalion, Royal Australian Regiment (7 RAR) had patrolled forward unaware of the presence of a large Việt Cộng main force unit nearby. Clashing with a reinforced company from the Việt Cộng 3rd Battalion, 274th Regiment, a classic encounter battle ensued between two forces of roughly equal size. Fought at close quarters in dense jungle amid a heavy monsoon rain, both sides suffered heavy casualties as neither was able to gain an advantage. Finally, after a battle lasting several hours, the Australian artillery proved decisive and the Việt Cộng were forced to withdraw, dragging many of their dead from the battlefield after having suffered crippling losses.

The 23rd Battalion was an infantry battalion 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.

The German attacks on Nauru were conducted in December 1940 on the island of Nauru, an Australian-administered League of Nations mandate in the Central Pacific. Nauru was of considerable strategic importance for its phosphate resources. The attacks were conducted by auxiliary cruisers between 6 and 8 December and on 27 December. The raiders sank five Allied merchant ships and inflicted serious damage on Nauru's economically important phosphate-loading facilities. Under the terms of the League of Nations mandate, the island had no fortifications or military facilities and was consequently undefended, with the German forces unimpeded in their operations.

The two attacks were the most effective operations conducted by German raiders in the Pacific Ocean in World War II. They disrupted supplies of phosphate to Australia, New Zealand and Japan, which reduced agricultural production in these countries. In response, Allied naval vessels were deployed to protect Nauru and nearby Ocean Island and escort shipping in the South Pacific. Small garrisons were also established to protect the two islands, but Nauru was ultimately evacuated of most non-indigenous residents following the attack on Pearl Harbor and was invaded by the Japanese in 1942.

Ivor Ewing McIntyre, CBE, AFC & Bar (6 October 1899 – 12 March 1928) was a pilot in the Royal Australian Air Force (RAAF). He gained national recognition in 1924 when he and Wing Commander Stanley Goble became the first men to circumnavigate Australia by air. Two years later, under the command of Group Captain Richard Williams, McIntyre piloted the first international flight undertaken by an RAAF plane and crew; this feat earned him the first Air Force Cross awarded to an RAAF member. Born and raised in England, McIntyre had served with the Royal Naval Air Service and Royal Air Force in World War I before joining the RAAF. He left the Air Force in 1927 to become an instructor with the South Australian branch of the Australian Aero Club, and died after a plane crash the following year. (Full article...)

The First Australian Imperial Force (1st AIF) was the main expeditionary force of the Australian Army during the First World War. It was formed as the Australian Imperial Force (AIF) following Britain's declaration of war on Germany on 15 August 1914, with an initial strength of one infantry division and one light horse brigade. The infantry division subsequently fought at Gallipoli between April and December 1915, with a newly raised second division, as well as three light horse brigades, reinforcing the committed units.

After being evacuated to Egypt, the AIF was expanded to five infantry divisions, which were committed to the fighting in France and Belgium along the Western Front in March 1916. A sixth infantry division was partially raised in 1917 in the United Kingdom, but was broken up and used as reinforcements following heavy casualties on the Western Front. Meanwhile, two mounted divisions remained in the Middle East to fight against Turkish forces in the Sinai and Palestine. The AIF included the Australian Flying Corps (AFC), the predecessor to the Royal Australian Air Force, which consisted of four combat and four training squadrons that were deployed to the United Kingdom, the Western Front and the Middle East throughout the war.

The Battle of Suoi Bong Trang (23–24 February 1966) was an engagement fought between US, Australian and New Zealand forces, and the Viet Cong and North Vietnamese Army during the Vietnam War. The battle occurred during Operation Rolling Stone, an American security operation to protect engineers building a tactically important road in the vicinity of Tan Binh, in central Binh Duong Province, 30 kilometres (19 mi) north-west of Bien Hoa airbase. During the fighting, soldiers from the US 1st Brigade, 1st Infantry Division and the 1st Battalion, Royal Australian Regiment (1 RAR), which had been attached for the operation, fought off a regimental-sized Viet Cong night assault. Repulsed by massed firepower from artillery and tanks, the Viet Cong suffered heavy casualties and were forced to withdraw by morning. After the attack, the Americans and Australians made no attempt to pursue the Viet Cong, focusing on securing the battlefield and evacuating their own casualties. The Viet Cong continued to harass the American sappers with occasional sniper and mortar fire, but these tactics proved ineffective, and the road was completed by 2 March. (Full article...)
