Hi Matt,
I agree with Geoff.
Mangrove Mountain (Pony Club).
Its not that far from you, just over 50k I reckom up the F3.
Check the location thread at the top of the Star Parties Forum.
Skies are as good as it gets within 100k.
there are facilities.
There are a great group of guys (occasional gals) that will help you enjoy your hobby.
And it free!
And you won't get arrested for setting up a rocket launcher in a public place.
Of course, if you want even darker skies, you could try Wiruna (near Mudgee). Site owned by Astro Socity NSW. (Fees apply)
Or better still, Bretti (free csmping reserve) 32k north of Gloucester. There is a group of us going up there end of July for four days near new moon. (See star parties thread)
Hope to see you soon, I'd be keen to have a look through your new DOB.
