Australian Light Horse were mounted troops with characteristics of both cavalry and mounted infantry, who served in the Second Boer War and World War I. During the inter-war years, a number of regiments were raised as part of Australia's part-time military force. These units were gradually mechanised either before or during World War II, although only a small number undertook operational service during the war. A number of Australian light horse units are still in existence today.
The First Australian Imperial Force was the main expeditionary force of the Australian Army during World War I. It was formed as the Australian Imperial Force on 15 August 1914, following Britain's declaration of war on Germany, initially with a strength of one infantry division and one light horse brigade. The infantry division subsequently fought at Gallipoli between April and December 1915, being reinforced by a second division which was later raised, as well as three light horse brigades. 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 II ANZAC Corps was an Australian and New Zealand First World War army corps. Formed in early 1916 in Egypt in the wake of the failed Gallipoli campaign, it initially consisted of two Australian divisions, and was sent to the Western Front in mid-1916. It then took part in the fighting in France and Belgium throughout 1916 and 1917, during which time it consisted of New Zealand, Australian and British divisions. In November 1917, the corps was subsumed in to the Australian Corps, which concentrated all five Australian infantry divisions. After this, the corps was reformed as the British XXII Corps.
The Australian Corps was a World War I army corps that contained all five Australian infantry divisions serving on the Western Front. It was the largest corps fielded by the British Empire in France. At its peak the Australian Corps numbered 109,881 men. By 1918 the headquarters consisted of more than 300 personnel of all ranks, including senior staff officers, as well as supporting personnel such as clerks, drivers and batmen. Formed on 1 November 1917, the corps replaced I Anzac Corps while II Anzac Corps, which contained the New Zealand Division, became the British XXII Corps on 31 December. While its structure varied, Australian Corps usually included 4–5 infantry divisions, corps artillery and heavy artillery, a corps flying squadron and captive balloon sections, anti-aircraft batteries, corps engineers, corps mounted troops, ordnance workshops, medical and dental units, transport, salvage and an employment company.
The 5th Battalion was an infantry battalion of the Australian Army. Raised in Victoria as part of the First Australian Imperial Force for service during World War I, the battalion formed part of the 2nd Brigade, attached to the 1st Division. It participated in the landing at Anzac Cove on 25 April 1915, coming ashore in the second wave, before taking part in the fighting at Krithia and then at Lone Pine. In December 1915 the battalion was withdrawn from the peninsula and returned to Egypt where it was involved in defending the Suez Canal until being transferred to the Western Front in France in early 1916. After that, over the course of the next two and a half years the 5th Battalion was rotated in and out of the front line and took part in a number of significant battles including at Pozieres, Ypres, Amiens and the Hindenburg Line. Following the end of the war, the battalion was disbanded and its personnel returned to Australia. The battalion was re-raised during the inter-war years as a part-time unit and was later mobilised during World War II, but did not serve overseas. During the post war period, the battalion has existed at various times before being subsumed into the 5th/6th Battalion, Royal Victoria Regiment.
The 8th Battalion was an infantry battalion of the Australian Army. Initially raised in 1914 for the First Australian Imperial Force during the First World War the battalion was completely recruited from Victoria and formed part of the 2nd Brigade, 1st Division. During the war it fought at Gallipoli and in France and Belgium on the Western Front. It was disbanded in 1919, before being re-raised as a Militia battalion in 1921. During the Second World War the 8th Battalion was used primarily as a garrison unit before taking part in the Bougainville campaign late in the war. It was disbanded again in 1946 during the demobilisation process, although it was reformed again in 1948 when it was amalgamated with the 7th Battalion. Today, its honours and traditions are perpetuated by the 8th/7th Battalion, Royal Victoria Regiment.

The battalion was recruited from Tasmania, South Australia and Western Australia and formed part of the 3rd Brigade, 1st Division.

During the interwar years, the 12th Battalion was re-raised as a part-time military unit and during the Second World War undertook garrison duties in Australia, but did not see combat. Today its lineage is perpetuated by the 12th/40th Battalion, Royal Tasmania Regiment, a unit which continues to serve in the Australian Army Reserve.

The ANZAC acronym came from the Australian and New Zealand Army Corps, formed in Egypt prior to the Gallipoli Campaign during the First World War. The corps was the higher formation for all Australian and New Zealand soldiers. It then gave its name to ANZAC Cove, on the Gallipoli peninsula, and at first was only used to identify the men who took part in the Gallipoli landings, although it later came to mean "any Australian or New Zealand soldier of the First World War." Both the 'ANZAC' and the 'Anzac' versions of the acronym have been protected by the Commonwealth Government of Australia.
