Hi Chris,
> looking for suggestions of dark sky sites with a view to the North within a couple of hours of Brisbane - preferably West or NW of Brisbane.
There aren't any. SEQ is all light pollution.
It depends how you define a dark sky site? You have to go a long way to minimise the LP hump from SEQ. Even at the Astrofest site, just north of Moore, there is a substantial skyglow to the southeast and east from Brisbane and the sunshine coast but ok overhead and to the W and NW. The LP follows the Warrego Highway for a long way inland.
Lake Coolmunda is 15km east of Inglewood and away from the runs of light pollution. It is 250 km/3hrs from Brisbane. There's a public campground, and a private caravan park with on-site vans or you can book into a motel in Inglewood and reach the lake fairly quickly in 10-15 mins.
Regards
Joe Cali
