Ahhh! VIC. The way I see it is It's based on how far You are willing to travel:-
i.e.
2 1/2 hours out of Melbourne will get you to Port Campbell, Dunkeld, The Grampians, Stawell, Charlton, Echuca, Wangaratta, Mt. Bullar, Sale, Yarram, Wilsons Prom, All nice and
very very dark sky zones May 7+ visible! some light polution near 5deg of horizons & from some nearby towns.
Closer in say
1 1/2 hours out of Melbourne will get you to Castlemaine, Seymour, Yea, Marysville, Warragul, Wonthagi, All
nice and very dark sky zones some light polution near 15deg of horizons & from nearby towns.
Closer in say
1 hour out of Melbourne will get you to Snake Valley, Macedon, Wallan, Healsville, Phillip Island
still some good dark sky available. some light polution near 25 deg of horizons & from nearby towns.
You'll need to weigh up the equipment taken, power availability, set up time and a return trip V an overnight stay (accommodation) required.
