I've seen this place and thought about heading out. On the topic of dark sites & farmstays my cousins have a farm just outside Griffith in SW NSW. I was there last week on a work trip and was amazed how good the sky was even with full moon up. They rent a large cottage out and a small flat. They often get astronomy groups from melbourne coming up for the dark skies. I'm heading out for the june long week as its a new moon. Can't wait. Add to that the great farm activites to do in the day and its a great time away. Here's the link. I guess the only plus about Magellan is they have scopes and such. But if your just after a dark site i highly recommend Griffith.
