All great advice from Gary, Moh.
We stayed at the Warrumbungles Mountain Motel when we went on our MAS trip late last year and it was very close to the AAO. They were looking at an ownership change back then, so I don't know where that leaves you - most probably OK of course. Out the back of the motel (creek side) you will find acres of lawn - setup furthest away from the room lights and you'll be in great shape.
The Chinese restaurant in town was, quite frankly, sensational. It actually pulls up well next to some of the better-known restaurants along Dixon Street.
Here are some people you might recognise enjoying dinner in that very Chinese restaurant Moh...
