I can appreciate that. And while evidence of Aboriginal life at some sites might be scant (age and geology being big factors), I don't think it would be an insane inconvenience to work around them for many things outside of very massive operations like mines, even if there are loads of sites. I suspect the significance of these sites is being overplayed as a negotiating tactic on the back of the Rio Tinto incident. As it was, one of the authorities demoted half of the sites. On the other hand, if there was a broad area of historical interest (heavily frequented by nomads, or well-preserved), usually it'd be set aside. It's possible that the best examples already have been.
