Fred.If you google miles show ground admin it will put you to a facebook location. I don't use facebook myself and the wife is not here at the moment to use her poota. Try it mate I hope this helps..Alan. Good luck.
Fred,
we stayed at Miles Showgrounds a couple of months ago - not nearly as good as the Theodore showgrounds, and more expensive.
We only stayed one night at Miles, then moved on to a nice free camp, at Caliguel Lagoon, near Condamine.
