In addition, through the process of re-roling, the several light horse, armoured or cavalry units have also contributed to the regiment's history such as the 6th New South Wales Mounted Rifles, the 6th Light Horse and the 6th Armoured Regiment.

[1] The regiment was formed in 1960 as a result the amalgamation of all the Citizen's Military Force infantry battalions in New South Wales.

[2] This came about through an Army-wide reorganisation of regionally based infantry battalions and the formation of multi-battalion state-based regiments.

The first battle honour received was "Suakin 1885", which was awarded to regiment due to the commitment of a 767-strong New South Wales force consisting of four infantry companies, artillery, and a field ambulance.

[11] The 1st and 2nd Battalions received a unique battle honour, "Herbertshohe", as they were formed from personnel who had previously served in the Australian Naval and Military Expeditionary Force that fought in German New Guinea.
