Federation in 1901 brought with it a remodelling of the Australian defence forces on 1 July 1903 when this unit was given the name 13th (Queensland Mounted Infantry) Australian Light Horse (13th (QMI) ALH). A re-organisation of Australian defences as a consequence of the 1910 Kitchener Report led to the creation of Military Districts. Queensland was designated as the 1st Military District. Military units renamed throughout Australia using Queensland as the beginning numbers and so the 13th (QMI) ALH became the 2nd (QMI) ALH.
