The way I see it is It' based on how far You are willing to travel
i.e. 1 1/2 hours out of Melbourne will get you to Castlemaine, Seymour, Yea, Marysville, Warragul, Wonthagi, All nice and very dark sky zones.
Closer in say 1 hour out of Melbourne will get you to Snake Valley, Macedon, Wallan, Healsville, Phillip Island still good dark sky available.
You'll need to weigh up the equipment taken, power availability, set up time and a return trip V an overnight stay (accommodation) required.
