Cooby Creek Tracking Station, Satellite tracking facility near Toowoomba, Australia

Cooby Creek Tracking Station stood 22.5 km north of Toowoomba, Queensland, near Cooby Dam in a radio quiet zone without powerlines. It was assembled from transportables the size of semi-trailers, shipped to Australia and trucked from Brisbane; three bolted together formed the Operations Centre and one held telemetry and command. The whole station packed into seven semi-trailers, with a 12-metre parabolic antenna giving an unrestricted 180-degree view.

Built in 1966 near Cooby Dam to support NASA's Application Technology Satellite Program, the station joined the Spacecraft Tracking and Data Acquisition Network. Between 1967 and 1970 its staff ran NASA-directed communication experiments that fed into Apollo systems. It closed in 1970; former employees held a reunion on site in October 2016.

On 6 June 1967 the station received the first television program from outside Australia to reach the Australian east coast, a broadcast from Expo 67. On 25 June 1967 it took part in Our World, linking 24 countries to Brisbane, Sydney, Melbourne and Adelaide. It was also the initial receiving point for the Apollo 11 moonwalk video, re-sent to the USA by satellite up-link.

The station stood on high ground 22.5 km north of Toowoomba, chosen so that hills to the south and south-west screened man-made radio interference while the lower north-west horizon allowed low-angle tracking. The antenna was arranged for an unrestricted 180-degree view. Staff mostly lived in Toowoomba and were collected by a company van.

The facility employed advanced receiver technology including cryogenically cooled maser devices and Klystron power amplifiers to communicate with geostationary satellites. These specialized components allowed the station to detect and decode extremely weak space signals.
