What's going on with Australia is reburying the remains of Mungo Man and Mungo Lady?

Mungo Man and Mungo Lady are the oldest human remains found in Australia

I gathered it was something to do with Aboriginal communities but I don't understand why remains that are 40,000 years + old are being treated this way?

Is there anything else that could be learned from them or are they basically tapped out in that regard?

Is the government forcing this to happen?
