How long do you plan to live there? You might get away with it for a few months, but you’d always be living a version of a shadow existence. Can’t join the library. Possible trouble proving your address for a drivers license, enrolling a child in school, Medicare etc. lots of government services require a street address. What address would you provide for the electoral roll? Over the years I’ve had many interactions with my local government staff and elected representatives. Local friends who know where I live have successfully stood for Council. Do you really want to be hiding your address from the people who manage your local community, and denying yourself access to services?
