5th Engineer Regiment (Australia)

5th Engineer Regiment  is a Reserve unit of the Royal Australian Engineers. Originally raised as the "5th Combat Engineer Regiment", it is based in Penrith, Sydney, with one of its sub-units based in Canberra at the HMAS Harman multi-user depot.

In late 2013, the regiment was reorganised, when two sub-units – 101st Construction Squadron and the Littoral and Riverine Survey Squadron – were transferred from the 21st Construction Regiment, following the decision to disband that unit. The regiment subsequently assumed the designation of the "5th Engineer Regiment".
