The Astronomical Society of South Australia was founded in 1892 and is one of the largest organisations of its kind in Australia with over 750 members. Our mission is to observe, understand, share and to enjoy the wonders of the Universe. Most importantly, we promote Astronomy to the public to inspire and enrich the astronomer in everyone. Membership is open to anyone with an interest in Astronomy. You do not need to own a telescope. The Society is also the only representative body for amateur astronomers in the state of South Australia.
