The regiment was formed on 13 January 2003, in order to serve as the administrative headquarters for a number of
squadron-level subunits, which had previously been independent. Attached to the
6th Brigade, the regiment's subunits – the
17th and 21st Construction Squadrons, the 1st Topographical Survey Squadron and the 20th Explosive Ordnance Disposal Squadron – were spread across three different locations:
Gallipoli Barracks in
Enoggera;
RAAF Base Amberley in
Amberley; and
Holsworthy Barracks in
Holsworthy. These subunits are supported by a fifth subunit, the Operational Support Squadron. By virtue of the regiment's function, the majority of its 600 personnel are regular soldiers drawn from the
Royal Australian Engineers, The 17th Construction Squadron relocated to RAAF Base Amberley in Queensland from Holsworthy Barracks in New South Wales. When the 6th Brigade was disbanded in December 2024 the 6th Engineer Support Regiment was transferred to the
17th Sustainment Brigade. ==Structure==
