Live the Dream.
There looks like plenty of area to set up a little camping area, little camp kitchen, little fire place, OZSTOC shop, little minor repair workshop.
No doubt there would be some volunteers to assist you with running the cafe, and would enjoy the ride and from work.
I can make a mean instant coffee (not those fancy coffee's) and can empty bins and clear tables, it would be like living at home, but I would enjoy it more.
Cheers
Dave
