Info required - Cunnamulla to Winton via Bridsville

Hello,

I would like info on the condition of the roads for the following route:
Cunnamulla – Innamincka
Innamincka – Birdsville via Cordillo Downs
Birdsville – Boulia via Bedourie
Bedourie – Winton

I will be travelling in a Nissan Patrol 4.2 Turbo Diesel towing an off-road camper trailer. We will be travelling end of May/early June. We are planning to bush camp most of this route where possible. I imagine there would be plenty of travellers at this time doing these roads?

Any advice would be appreciated.

Thanks
Evan
