and

downunder Greg. You are in for a real treat.
Surfers Paradise and the Gold Coast generally are very light polluted, but if you are prepared to travel for an hour or so West and South West you will find plenty of dark sites. In behind the Gold Coast is the Lamington National Park. It is on a high plateau which would be good, but the best part is once you get down the west side of the plateau you are blocked from the lights of the Gold Coast.

You can go even further West South west to the Girraween and the Boarder Ranges. But I would warn you not to go there. You won't want to go home if you do
There are a number of members in the area so hopefully they will pop in and give more specific advice. Of course you would be welcome to come up the north coast (Sunshine Coast), north of Brisbane where we have much better skies than those south of Brisbane.
Anyway check the map and you will get an idea of what is around the Gold Coast.
