The Australian and New Zealand Army Corps (ANZAC) was formed from the AIF and NZEF in preparation for the Gallipoli Campaign in 1915 and was commanded by Birdwood. Initially the corps consisted of the 1st Australian Division, the New Zealand and Australian Division, and two mounted brigades—the Australian 1st Light Horse Brigade and the New Zealand Mounted Rifles Brigade—although when first deployed to Gallipoli in April, it did so without its mounted formations, as the terrain was considered unsuitable. However, in May, both brigades were dismounted and deployed along with the 2nd and 3rd Light Horse Brigades as reinforcements. Later, as the campaign continued the corps was reinforced further by the 2nd Australian Division, which began arriving from August 1915. In February 1916, it was reorganised into I and II ANZAC Corps in Egypt following the evacuation from Gallipoli and the subsequent expansion of the AIF.{{sfn|Fleming|2012|pp=5–6}}

I ANZAC Corps included the Australian 1st and 2nd Divisions and the New Zealand Division. The New Zealand Division was later transferred to the II ANZAC Corps in July 1916 and was replaced by the Australian 3rd Division in I ANZAC. Initially employed in Egypt as part of the defence of the [[Suez Canal]], it was transferred to the Western Front in March 1916. II ANZAC Corps included the Australian 4th and 5th Divisions, forming in Egypt it transferred to France in July 1916.{{sfn|Fleming|2012|p=6}} In November 1917 the five Australian divisions of I and II ANZAC Corps merged to become the Australian Corps, while the British and New Zealand elements in each corps became the [[XXII Corps (United Kingdom)|British XXII Corps]]. The Australian Corps was the largest corps fielded by the British Empire in France, providing just over 10 percent of the manning of the BEF.{{sfn|Kuring|2004|p=70}} At its peak it numbered 109,881 men.{{sfn|Fleming|2012|p=7}} Corps troops raised included the [[13th Light Horse Regiment (Australia)|13th Light Horse Regiment]] and three army artillery brigades.{{sfn|Palazzo|2001|p=68}} Each corps also included a [[Australian Cycling Corps|cyclist battalion]].{{sfn|Fitzpatrick|1983|pp=31–38}}

Meanwhile, the majority of the Australian Light Horse had remained in the Middle East and subsequently served in Egypt, Sinai, Palestine and Syria with the Desert Column of the Egyptian Expeditionary Force. In August 1917 the column was expanded to become the Desert Mounted Corps, which consisted of the ANZAC Mounted Division, Australian Mounted Division and the [[Imperial Camel Corps Brigade]] (which included a number of Australian, British and New Zealand camel companies).{{sfn|Fleming|2012|pp=7–8}} In contrast to the static [[trench warfare]] that developed in Europe, the troops in the Middle East mostly experienced a more fluid form of warfare involving manoeuvre and combined arms tactics.{{sfn|Blaxland|2006|p=24}}
