Yes. Bought in QLD. Registered in NSW. The previous owner deregistered it in QLD and I drove it back on an unregistered vehicle permit.
If you do it that way you can drive it all the way home to SYD on the permit and the prev owner gets their rego back. And then register it at home as in NSW you are allowed to drive from your house to a testing station whilst unregistered. . You'll need a full inspection including weighbridge certificate to register it in NSW if you are registering an unregistered trailer
Make sense?
