I know 2 who have been to the Coonabarabran Festival of the Stars.
As the web site says, "The week long celebration all things astronomical caters for all tastes, including poetry reading, concerts, stargazing nights, science in the pub and tours of the professional observatories." The aim to to have a very broad appeal, so actual observing is only a small part of the activites. I am told that these events tend to get a lot of beginners who are not heavily into amateur observational astronomy. If you want some serious stargazing, the star parties glen has provided are recommended.
Otherwise you could try the Magellan Observatory:
