from the prewar years until recent decades. The museum is open every day except Monday. RAAF Williams, Laverton Laverton is the third oldest RAAF base, being built in 1925 at the same time as RAAF Base Richmond, which was opened slightly before Laverton. Located approximately from Point Cook, Laverton is the home of Headquarters Air Force Training Group (formerly Training Command). It also contains all the administrative functions of RAAF Williams. Other units at Laverton are the ADF School of Languages, Defence International Training Centre (DITC), Director General Technical Airworthiness, No. 21 (City of Melbourne) Squadron (RAAF Active Reserve) and a number of smaller sub-units. It also hosts an element of 8th/7th Battalion of the Royal Victoria Regiment, Australian Army Reserve, as well as elements of the Defence Materiel Organisation (DMO). In 1946 Laverton played host to the first flight of the newly formed Trans Australia Airlines, its Douglas DC-3 VH-AES Hawdon forced to use the base as operations at Essendon had become adversely affected by recent heavy rains. The base hosted the shotgun portion of the shooting events for the 1956 Summer Olympics. Laverton's runway was decommissioned September 1996. In early 2007 the Victorian Government gave approval for the land that was formerly the Laverton airfield and runway to be developed into the new suburb of Williams Landing. Three areas totalling were set aside for conservation. More than of nationally significant native grassland outside the reserves was permitted to be cleared by the state- and federal governments. Williams Landing is being developed into a transit-oriented development, major activity centre and employment node. As well as being a major activity centre and employment node, there will also be four residential neighbourhoods each with their own distinctive character. Construction of Williams Landing commenced in late 2007 and is due for completion by 2025. In 2016 it was speculated that the Department of Defence would completely shut down Laverton and its land sold under plans by the RAAF to consolidate its facilities towards northern Australia.
