ACTION’s southern depot is located in the Tuggeranong suburb of Greenway, and is the only depot with CNG fuelling facilities.

At Kingston, the original depot was located near the Power Station.

When Ainslie Depot opened in June 1929, it consisted of two garages, which originally came from the Molonglo Construction camp

Initially, buses from Kingston serviced the new suburbs in Woden Valley. The first stage of the Woden Depot, housing 44 buses was completed on 16 April 1974. A second stage, also housing 44 buses was completed on 14 July 1975

Although a public bus service to Belconnen commenced in 1967, it was not until 1979 that a depot was available in the new town. Problems with the design of the depot followed by budgetary restraints caused delays to the start of construction.
