Parkes Observatory is some 300km west of Sydney in the Central West of NSW, in the heart of Wiradjuri country. The site was chosen in 1956 for CSIRO’s largest radio astronomy project to that time, a 64-m fully-steerable parabolic dish commissioned in 1961 and still the largest dedicated “single dish” radio telescope in the Southern Hemisphere.
The site was selected to be distant from any large conurbation, for protection from terrestrial radio frequency interference (RFI), yet within relatively convenient distance of Sydney. Situated in a shallow and fertile valley about 20km North of the town of Parkes, it is screened from the town by a line of hills affording protection from terrestrial RFI,

The choice of the site was supported by the local Shire Council at the time, and the telescope has become an icon of the Central West and of Australian science. It has been described as Australia’s most productive scientific instrument.
In 2020 the Parkes telescopes received Wiradjuri names from the Traditional Owners.
