The 6th Light Horse Regiment was raised at Sydney in September 1914 as part of the all volunteer Australian Imperial Force,[1] and comprised twenty-five officers and 497 other ranks serving in three squadrons, each of six troops.

In action one man of each section, was nominated as a horse holder reducing the regiment's rifle strength by a quarter.

The band of the 6th Light Horse played So Long written by Australian composer May Summerbelle as the infantry sailed.

During the campaign they fought mainly defensive actions around the Anzac Cove beachhead, until being withdrawn in December 1915 as part of the Allied evacuation from the peninsula.

The 6th Light Horse then took part in an operation along the River Jordan, which ended with the capture of Aman and Es Salt.

The Ottoman Empire surrendered soon after that and before returning home the regiment was sent back to Egypt to provide internal security as riots broke out there.

[8] Through this process, the 6th Light Horse was re-raised as a Citizens Forces unit within the 2nd Military District in the state of New South Wales, drawing lineage from the 9th Light Horse (New South Wales Mounted Rifles), which had been formed in 1912 and which traced its origins back to the 2nd Australian Light Horse Regiment (New South Wales Mounted Rifles) that had been formed in 1903 as part of the amalgamation of Australia's colonial forces into the Australian Army after Federation.

[9] The regiment was deemed surplus to requirements and, as part of a gradual demobilisation of the Australian Army, on 19 February 1943, it was disbanded without having seen operational service during the war.
