I'ts great Snap, it's called the Donnybrook Transit Park (council owned), the bookings and keys etc are obtained from the BP on the main highway through town.   About $26 a night I think and each site has it's own ensuite in a separate building, drive through sites with concrete pads on a nicely grassed area and power or non power  (cheaper).    I was there a few months ago, highly recommend it!

Oooops......just saw Pete's post, I didn't realise there was one in Qld........now you can see why I made the thread about making heading more descriptive, if it had Donnybrook Qld I wouldn't have bothered replying......

Always better to put the state as there are some similar names in various states, eg; Gin Gin in WA, Gin Gin in Qld, also Crystal Brook Caravan Park in WA, also one by the same name in SA.
