What We Do

We are based in the South Western Region of Sydney, NSW, Australia, including Campbelltown, Camden, Liverpool and Wollondilly.

We hold dark sky observing sessions for our members.

We organise the Macarthur Astronomy Forum, bringing local and international professional astronomers to address us on their research.

We organise community astronomy nights at Campbelltown Rotary Observatory at Western Sydney University and we collaborate with local institutions to broaden public understanding of the Universe.
