A small suite of imaging and spectroscopic instrumentation is available for use with the RSAA research telescopes. The RSAA Time Assignment Committee (TAC) meets quarterly to consider applications for use of RSAA telescopes and instruments from astronomers at institutions around Australia.

Astronomers at RSAA also have access to telescopes around the world through the RSAA and Australia's research partnerships and time-sharing agreements. These include the Gemini Observatory's twin 8m telescopes, the 10m Keck telescopes and 8.2m Subaru telescope in Hawaii (through a time-exchange agreement with Gemini), and the Magellan 6.5m telescopes in Chile. See the Australian Gemini Office website for more information.

Observers at ANU can also apply for time using the 2m Faulkes Telescope South at SSO, which is part of the Los Cumbres Observatory Global Telescope Network (LCOGT), and the former ANU 40 inch telescope that is now operated by the privately-owned Millroy Observatory near Coonabarabran.
