Hello Bojan, fellow Mt Waverlian! I was checking out the
Taggerty Pioneer Settlement just a few kms past Buxton the other weekend, and was thinking the place would be perfect for a star party. There is plenty of budget accommodation on site and a big open field at the back of the property that is just begging to be populated with telescopes and observers.
It's probably farther than you had in mind: another 60km after Lilydale, but a pretty cruisy 60km, unlike the drive through burbs before you get to Lilydale. Skies are very nice and dark on good nights.
