Elsewhere in these comments are people saying that landowners will remove (public) signage(!), which might impact what the parks people can do?

Maybe a well-publicised term for a private easement that people recognise is treated in a particular way? I like that in the States, National Park means something, BLM means something, etc. Our designations in Australia don't seem as clear. We have Crown land, but I have no idea where to find out about it.

Private easement guides would be: You are a guest here on private land. Don't stray from the road, leave gates as you found them, livestock has right of way, no camping, etc.

Surely there's a balance in making reasonable land access available to people.
