Karumba to Chillagoe via Burke Development Road

The roads in good condition, but you have 560klms without available fuel. Was on part of it last week

Quite a good drive on decent quality gravel road, but you only pass Dunbar and one other property along the way, so there's no fuel or other services.
Plenty of spots to camp off the side of the road, but very little traffic when we did it last year - apart from a series of mysterious drive-bys in the middle of the night when we were camped - presumably from a nearby station.
