Australian Defence Satellite Communications Station

The surrounding buffer zone of 442 hectares is also owned by the Commonwealth and provides protection for the station against external electrical interference.

The antennas, of Australian design, were erected by a joint venture between AWA Defence Industries and Baulderstone Engineering.

Staff are drawn from the U.S. National Security Agency (NSA) and the Australian Signals Directorate (ASD), and the site is operated under the UKUSA Agreement.

[4] In 2007, after signing an agreement[5] it was announced that an additional but separate US military communications facility would be built within the grounds of the ADSCGS.

It will consist of three 19 m (62 ft) antennas and two smaller antennas making up a joint US-Australian ground station for the US Department of Defense Mobile User Objective System, a narrow-band networked satellite constellation for Ultra-High-Frequency satellite communications enabling secure all-weather and all-terrain 3-G mobile telecommunications.
