Thanks for the info. I'll be sure to check those places out.
ving, I'm not sure how accurate it is. The web site mentions:
Colours correspond to ratios between the artificial sky brightness and the natural sky brightness of: <0.01 (black), 0.01-0.11 (dark-gray), 0.11-0.33 (blue), 0.33-1 (green), 1-3 (yellow), 3-9 (orange), 9-27 (red), <27 (white). There's lots of info on how they collect the data on the web site but it's too much reading for me
If I find a good close-to-Sydney spot I'll definitely mention it on this board.
