No. 1 Aircraft Depot RAAF

No. 1 Aircraft Depot (No. 1 AD) was a maintenance unit of the Royal Australian Air Force (RAAF). Formed in July 1921 at RAAF Point Cook, Victoria, it relocated to the nearby RAAF Laverton in March 1926. As well as servicing aircraft and other equipment, in its early years, the depot supported survey flights in Australia and the Pacific region. It was also responsible for training maintenance staff.
