I second what Lancair70 said, go to Dubbo, the price of fuel is good and you can get lunch in the terminal as long as you arrive within an hour or so of a RPT flight.
A landing at YNYN (Nyngan) can be fun just so you can say you've had a proper Bogan experience in Bogan Shire
- there is no fuel in Nyngan though.
YBHI is a good little stop over and the locals are quite friendly, we got a lift in to town from a really friendly guy who flies a Jab who's name escapes me right now!
