road conditions

Hi Carol
As with all dirt roads the conditions can change but we did that road in 2019 from the Dig Tree past Haddon Corner. The first maybe 50km from the Dig Tree to the Cook Oil Field turn off was quite rocky, rough and slow going. From there through to where the Cordillo Road joins was narrower and a bit sandy but much smoother. From there you could turn left and go past Cordillo Downs to Birdsville or up past Haddon Corner and onto the Birdsville Rd. This last part was similar to the Birdsville Rd. It's all a very nice drive. I think you would have drive carefully if you thought your van wasn't up to it.
cheers

G'day Carol, hopefully someone can give you up to date info, it was too long ago I went through those roads, heck Adventure Way / Innamincka Rd was still unsealed.
The dig tree road was a good station track.

If Arrabury Rd has been graded it's like a highway, doesn't happen that often though.
It's a month out to the BRB, any feedback just also watch weather until then, if it gets wet it could be interesting.

Expect you'll be driving up from the dig tree north on the qld road (Nappa Merrie Rd) to Arrabury Rd, I haven't done that up to Arrabury, but imagine it should be graded at times.
