The roads from Tibboorburra to Innaminka via Cameron's Cnr & Moomba would be no more difficult or isolated than the Oodnadatta track. Taken steady & with the usual preparations a car should have little problem. (if it doesn't rain) Craig......

Hell......roads vary in condition so much through there, depending on maintenance and weather patterns....if clearance presents no problems I feel sure the surfaces in some places will play havoc with your tyres.....better have at least two spares and some coms for back-up. It has rained up there recently....you could find washouts that have been ungraded.....dust washed away exposing kilometres of stones....or it could be great ! ....you just need to be able to cope with what you find at any particular time.

Ralvona,
a car is fine on that trip (many locals use standard cars).
Keep speed down on rougher stuff, have enough spares, and watch clearance of sump on dips and rises.
