The Complete List of Aeradio/FSUs in WA
As of 1 Oct 1963, the Aeradio units (later to be known as Flight Service units after 1965) in WA were:
Albany: Aerodrome Flight Information Zone (AFIZ) SFC/3000ft AMSL
Broome: Flight Information Zone (FIZ), later to become known as Flight Information Areas (FIA); Derby was only an AFIZ at that time
Carnarvon: FIZ
Cocos Island: FIZ
Derby: AFIZ SFC/3000ft AMSL
Forrest: AFIZ SFC/3000ft AMSL
Geraldton: AFIZ SFC/3000ft AMSL
Kalgoorlie: FIZ
Meekatharra: FIZ
Port Hedland: FIZ (no control tower and no FSC then)
Wittenoom: AFIZ SFC/3000ft AMSL
Wyndham: FIZ
Prior to '63, there were also Aeradio units located at Glenroy Station (Air Beef Scheme), Halls Creek, and Onslow but these all closed before that date.
The Broome FSU was closed in '71 and Derby was expanded to assume Broome’s FIA functions, an FSU was established at Karratha (AFIZ SFC/5000ft AMSL) sometime around 1972/73 to support the increased air traffic servicing the Hamersley railway and mining operations at Tom Price and Paraburdoo, the Wittenoom and Forrest FSUs closed in ’72 and ‘73, the Albany FSU was closed in ’74 and the Wyndham FSU was decommissioned and its functions transferred to the newly established FSU at Kununurra sometime around 1977.
After 1985, with the advent of satellite communications capability all remaining FSUs were slowly consolidated into the Perth FSC under the Integration, and Modernisation of Air Traffic Services (IMAS) project which was completed sometime around ’95.
I’m a bit hazy now on some of the dates, so quite happy to be corrected.
