This is correct
If you currently do not exist on the NSW RTA computer they can not register anything into your name. I have had mates have to get 3rd party stat decs to state that their NSW holiday homes is a real address that they sleep at and that the boat trailer will be stored at and show attached bills and rates notice along with original passport ( they won't accept certified copies of anyything anymore) . If you don't have a NSW lic or existing relationship with the NSW RTA they won't deal with you. They will not accept a interstate lic etc etc as they can't look it up on their computer systems
It is a pain that we have state based organisations and they all have different rules and especially when they don't trust teh other states info.
