Sir Thomas Brisbane Planetarium

The Sir Thomas Brisbane Planetarium offers an accessible introduction to astronomy and space exploration in Brisbane. Its main attraction is the Cosmic Skydome, a 12.5-metre projection dome that recreates the night sky and presents immersive fulldome shows about planets, stars and constellations. Some sessions also include guided tours with expert astronomers, while children’s shows run for a shorter duration than the general audience sessions.

There is plenty to explore beyond the dome. The Display Zone and foyer include exhibits, models and interactive displays covering astronomy and space exploration. Current exhibitions include Earth: Our Blue Oasis, which looks at solar evolution and Earth’s wider cosmic environment; a display about Sir Thomas Brisbane’s life, governorship and astronomical work; and Skylore: Aboriginal and Torres Strait Islander Astronomy, featuring star knowledge shared by Elders and recognising the long history of First Australians observing the southern skies.

The venue is set within the Brisbane Botanic Gardens Mt Coot-tha, with a Sundial Courtyard on its eastern side. The courtyard provides a place to sit and view the large concrete, steel and glass sundial, while the nearby gardens make it possible to extend the visit into a broader day out. The Galaxy Gift Shop sells space-themed merchandise such as star charts, project kits and spacecraft. Admission to the Planetarium is free, although Cosmic Skydome shows have a fee and advance booking is recommended for popular sessions.

It suits families, with dedicated children’s shows and exhibits that encourage questions about space, as well as solo visitors and adults interested in astronomy or the history of science. School groups can book curriculum-linked programs on the night sky, Solar System and space technologies, including expert question-and-answer time. The Cosmic Skydome can also be hired for seminars, presentations and social events, with theatre seating for up to 125 people and foyer, display and covered courtyard spaces for functions of up to 100 guests. Free parking is available in the gardens’ main car park, and buses stop at the gardens.
