The 2nd Regiment of the New South Wales Mounted Rifles was established in Sydney, along the same lines as the 1st Mounted Rifles, which was then still serving in South Africa. The 2nd Mounted Rifles consisted of five mounted rifle squadrons but, unlike the 1st Mounted Rifles, also had a machine gun section. The preference for recruits was for trained men who were "good shots and riders". They needed to be between the ages of 20 and 40, 5 foot 6 inch or taller, and have a chest measurement of 34 inches or larger.

The regiment left Sydney in March 1901 as part of the fifth contingent sent by New South Wales to the war. The regiment numbered 33 officers and 673 other ranks, with 700 horses. They disembarked at Port Elizabeth, South Africa, on 17 April.

From April to October the regiment served in west Transvaal, under the command of Major General Fetherstonhaugh, where they were involved in a number of operations, the principal being the capture of a large Boer convoy in May. The regiment subsequently captured another Boer convey of 106 wagons carrying supplies, ammunition, and a large number of cattle. Still under Fetherstonhaugh's command, from October the regiment served in east Transvaal, where 1,000 prisoners were captured.

On 4 May 1902 the regiment embarked at Cape Town for the return voyage to Australia, stopping at Albany and Melbourne, before reaching Sydney on 4 June.
