From Goondi you head north through Moonie. I'm not sure after that as I generally turn off for Dalby but I do know it is well-signposted to keep giong north for Rockhampton so I'd imagine it's well sign posted all the way.
Those roads are all good condition and it will be 100 all the way (110 in places).
There's some dodgy roads between Mudgee and Coona and I'm not fussed on the Wellington/Mudgee road. If you're thinking of going via Sofola you're kidding!!!!
So Dubbo's the go but turn off the Mitchell at Wheelers Lane (right) Road To by-pass town. If you need a coffee break though, give us a call and I'll see what I can do.........
From Dubbo you take 15km off the trip by going via Mendooran rather than Gilgandra. Roads are good and fewer cops, if you get my drift. Turnoff is right, 10km north of Dubbo at Brocklehurst - follw the signs after that.
