Moving and leaving people and places behind is always sad, but I think you'll find plenty of equally wonderful folk and places up here Matt (and a winning State of Origin team
).
Apart from Brisbane itself you have the Gold and Sunshine Coast (with more of us IIS'ers up here too) . There's also the Brisbane Astro Society, South East Qld Astro Society, etc, etc if you want a more formal club as well.
Personally I'd say just accept Ron's invite to a night's viewing at his place - the skies are dark, the people are friendly, and there's room for plenty more scopes yet!
Hope to meet you sometime soon,
Steve
