We discussed this a while back, at least so far as NSW is concerned.I have a question from the opposite point of view i.e. the private property owner. I have a commercial premise and rent out a car parking space. If somebody else parks in that parking space and I can't clamp wheels or levy a fine, what rights do I have to protect my own private property against people parking without my permission? Thanks in advance.
In short, the onus is on you (as landlord) to prevent unauthorised parking on your land.
