The best southern night sky I have ever seen in my life is Milford Sound in New Zealand once the the bar closes. Absolutely no distant light glow because you are in a sound. I spent half the night observing with my binoculars wishing I had a big light bucket Dobsonian telescope.
I think the best night sky I ever saw also was in New Zealand. Just up the road from Milford Sound on the east side of Mt Cook. I can envision Milford Sound being pretty awesome, but I wasn't there at night.
