I bought an r34 from vic not to long ago, these are the steps I had to take, but if your just moving you dont need to pay stamp duty. More than likely have to pay the rest though.
1. Get ID check done at regency (only if the car is registered in another state)
2. Go to motor vehicles (around the corner)
3. Take old plates off your car before you go into the motor vehicles and fill out the hand in plates form (saves you a trip and a waiting line)
4. Pay stamp duty (4% for ever $100 over $3000), registration, admin fees($21), new plates($21) and for the ID check ($think its was $30-$50)
5. Drive your car away
If you car still has registration you need to write a cover letter and fax it to the state stating you still have rego left, attach this letter with the form you receive back from the motor vehicles.
Hope this helps everyone.
