I think there's enough of a boost to aviation & other fields in the area right now with the water in Lake Eyre. And yes there has been talk of going over it again, but it's not going to happen.

Well apparently your call on that was wrong.
Flew over it this morning, vehicles on the ground around it and the entire Man has already been graded once, and looks like the deeper cuts bringing back the white contrast underneath have already commenced around his right arm.
Few more inquiries I made today revealed one of the local station owners has been hired to do the grading.
I'll try and post a few pics in the next few days as the work develops.
