The 3rd Light Horse Regiment was raised in Adelaide on 17 August 1914. Although most of its recruits were enlisted in South Australia, one of the regiment’s three squadrons was composed of Tasmanians and was raised and trained in Hobart. The two components sailed from their home ports in late October 1914 and arrived in Egypt in the second week of December. Here, they joined the 1st and 2nd Regiments to form the 1st Light Horse Brigade.
