Bev, Bev & Bev. For you and two heads. Think about it. You would be better served saving you shiny shells and pelts ( or whatever you use for currency) and flying to Melbourne or even Sydney for the BIG shows.
Plan to spend 2 -3 days and you will see everything available to the RV’r. You literally have everything laid out for you and if you’re ready to spend some Australian currency ( we tend to use that up this way) you may score a great deal.
There is no hope you would ever get anything like a big show in Tassie.
Sorry, facts of life and all that.
PS. I love Tasmania, and the locals
