Nope all the properties there are all old torrens title so they own the creeks and rivers there. There is very little crown land in that area.
You can look it up on the QLD Globe from dept of mines to see the boundaries of the properties.
Best to stay away from the place now, lots of angry people out there who don't want prospectors / fossickers going on their land. Can't blame them for being angry I would be too if someone went in and dug up my back yard, left a whole heap of rubbish and left the gates open all without permission.
