Depends on where you are moving to Pom.
I'd suggest NSW may not be where you should be aiming for.

As with every rego question on here, you will need to commission the assistance of an automotive engineer. Look one up that works in the state you are intending to move to and go from there.
If you are considering Victoria as a home, club rego (limited registration) may be your best hope at getting on the road with the least fuss.

Good luck
