What is this?

Hi,
Can anyone tell me what the clearing in the middle of this aerial image is? It is just to the south of Bruntons Bridge on the Thomson River and just to the north of the Cowwarr-Walhalla gravel road. I have tried searching online with no success, it obviously looks like it has been cleared and there are signs of some form of buildings, I looked for a track when driving the Cowwarr Road and couldnt find anything. Just curious as to what it is or might have been?
Thanks
