An easement is listed when you buy a property. It’s detailed on the property title, and has drawings showing where it is, and who has access.

These new laws were the complete opposite - as long as the property was larger than 1100m^2, it was assumed to be of cultural significance until proven otherwise. The landowner needs to notify aboriginal people (whoever that is?), then they take their feedback to apply for a permit from the government, then the government will notify aboriginal people (again, who?) then based on their feedback will issue a permit (or not). And this same process would apply wether you’re fixing the retic in your suburban backyard, or digging a billion tonne open cut mining pit in the Pilbara.
