The 17th Construction Squadron is an Australian Army unit consisting of personnel drawn mainly from the Royal Australian Engineers. Originally formed in 1949, the squadron is currently part of the 6th Engineer Support Regiment and is based at Holsworthy Barracks in Sydney, New South Wales. Personnel from the squadron have deployed on operations during the Vietnam War and the ongoing War in Afghanistan; they have also participated in peacekeeping operations in Namibia and East Timor. The squadron is regularly involved in the Army Aboriginal Community Assistance Program and has also been called upon to provide assistance to the wider Australian community following natural disasters, including most recently in the wake of the 2010–2011 Queensland floods.
