Welcome to the Astronomical Society of South Australia

The Astronomical Society of South Australia is the only representative body for amateur astronomy in the state of South Australia. Founded in 1892 and with around 700 members, it is the oldest and one of the largest organisations of its kind in Australia.

Our monthly meetings, which usually feature a guest speaker, are free, open to the public and visitors are most welcome to attend.
