RAAF Base Williams consists of two separate Air Force bases on the outskirts of Melbourne.
RAAF Base Williams Point Cook is the birthplace of the Royal Australia Air Force and has the oldest continually operating military airfield in the world.
Point Cook is home to Number 21(City of Melbourne) Squadron which provides airbase combat support to RAAF Base Williams. The RAAF Museum is also housed at Point Cook and in addition to an extensive collection of memorabilia it also has a large collection of retired RAAF aircraft. The RAAF Museum is the only Defence flying unit based at Point Cook.
The airfield at Point Cook is unique in that it is part of an operational RAAF Base, but is predominately used by a number of civilian organisations for pilot training with the Royal Melbourne Institute of Technology (RMIT) Flying Training school being the largest. RMIT commenced flying activities at Point Cook in 1995. The Point Cook Flying Club and Vintage Tiger Moth Joyflights also operate from Point Cook and the Victoria Police and Victoria Emergency Service also occasionally conduct helicopter operations at the Base. Aircraft from Essendon and Moorabbin based flying schools also use Point Cook airfield.
Point Cook has three runways, two asphalt and one grass.
An F/18A Hornet and a replica of the first aircraft flown at RAAF Williams Point Cook celebrate the Centenary of Military Aviation at Point Cook.
