Hi Aaron, we have a bit of a group in Mackay but the closest official club is in Townsville.
Our group is very casual and mainly keeps in touch though facebook, but we do manage to catch up in person a couple of times a year. A few of us also get involved in outreach nights at some of the local schools. We have a web page at
http://tropicalstargazers.webs.com/ as a starting point and a facebook group page with the name tropicalstargazers.
Cheers Rick
