Marianna Waterhole, Cordillo Downs Rd camping

We're looking for a camp between Birdsville and Innamincka. EO places has Marianna Waterhole as a possible camping spot. It's also a bit better positioned along the track than Cadelga. Has anyone camped there, or been told that they are not welcome? Tricorner burrs get a good run as a nuisance at Cadelga, presumably the same when camping anywhere along the road?
