Halls Gap Gardens Caravan Park, three nights from november 16th.
edit:
I haven't planned my course of action either side of that yet but the 16th will probably be arrive in the afternoon, unload and take a look around town, on the 17th do my own thing around the Grampians and the RTE lunch/dinner on the 18th.
My options for after that are open at this stage but I am considering going to Melbourne to get a nengajō photo of the Fairfield Industrial Dog Object in Fairfield. A nengajō is a Japanese style new year card which usually has a design related to the animal of the year. Next year will be the year of the dog. This was my 2015 equivalent (year of the sheep)
