The Anglo-Australian Telescope (AAT), which was opened in 1974 by HRH Prince Charles, is operated by ANU.

The ANU 2.3m Telescope was built in the early 1980s, at the initiative of the then director, Don Mathewson. The entire project was managed by the observatory's own technical staff, and a large amount of the construction was also undertaken in-house.

The Faulkes Telescope South is a Ritchey Chretien telescope that was designed and built in the United Kingdom and is now operated by the Las Cumbres Observatory.

GOTO-South forms part of an international network of wide-field optical telescopes to detect counterparts of gravitational-wave events.

The Huntsman Telescope is designed to take extremely faint images of astronomical objects in the Southern sky and is made up from an array of Canon telephoto lenses.

The iTelescope.Net facility at Siding Spring Observatory is the southern hemispheric station of a global network of small to medium sized robotic telescopes designed specifically for use by the public via the internet. It is its flagship observatory and was commissioned in January 2013.

The KMTNet aims primarily to discover extrasolar planets based on the analyses of gravitational microlensing phenomena, especially the detection of earth-mass planets in the habitable zone of their parent star.

Owned and operated by the Nicolaus Copernicus Astronomical Center in Torun, Poland, a branch of the Polish Academy of Sciences, the Solaris Telescope is a 20 inch Ritchey Chretien system that is being used to look for planets around eclipsing binary stars using precision photometry. 

SkyMapper is a state-of-the-art automated wide-field survey telescope that represents a new vehicle for scientific discovery. It is sited under the dark skies of Siding Spring Observatory near Coonabarabran, in central NSW.

HAT-South is a project to search for transiting extrasolar planets in the Southern Hemisphere. It uses a network of wide-field telescopes to monitor hundreds of thousands of bright stars, searching for the characteristic dip in light that occurs when a planet passes in front of its host star.

UNC PROMPT (Panchromatic Robotic Optical Monitoring and Polarimetry Telescopes), from the University of North Carolina at Chapel Hill, is made up of a number of observatories around the world. Here at SSO, UNC have installed four 17 inch Planewave telescopes.
