Chris certainly hit it on the head when he mentioned in his journal about how pricey it was... and how you're not going to see anything like it on any normal tourist tour.
For me, it was when we went to an Aboriginal rock art site, and realizing that the rock on the ground in front of the wall wasn't a rock at all, but a human skull. Then, suddenly, I saw the femurs and the other arm bones against the base of the wall. They were just all pushed over there, likely by the floodwaters as the site was next to a creek.
Looking in some of the other holes around there, we found a skull shoved into one, looking out. And under a rock shelf, another skull, this one painted red. Oh my, that's something you don't see everyday. The red ochre paint is an indication that the person was important.
A bit later, we found a five meter deep, horizontal 'cleft' in the rock... with maybe a dozen skulls and bones. And a paperbark parcel of bones, tied to some wooden branches, pushed up into a recess in the ceiling. The paperbark was quite intact; it looked like it was put there within the last five to ten years.
You just don't see that everyday.
