I know - my point is, there is ample proof that I am not a resident of Australia anymore both with the records held by Border Force and the fact that I left UK on my UK passport (after showing my Oz passport at checkin to satisfy entry requirements). So I wouldn't (or won't) need to get permission to leave as I am not bound by that rule, thankfully.
