Considering the number of people that have a pith over the rock when they get to the top of it, I think the indignation over a bit of semi naked dancing is a bit overdone.
If I was a rock I would rather be danced all over by this chic naked, than be pithed all over.
Heck! I'm not a rock and I wouild still rather she danced all over me naked.

Going back 30 years you could land a plane right up next to the rock and camp next to it and climb up it with no restriction.
The aboriginals used to have camps next to it at various times.
There was no mention or indication that it was anything sacred.
This sacred site bizzo seems to be something which has gained traction over the last 15 years.
