Buying car in NSW, want to drive it down to VIC and refund NSW rego

[-Tom]

Hey guys, I've been searching for the past hour but I haven't found any concrete answers.

I'm planning to purchase a car in NSW and bringing it back to VIC to register and drive here.
It has NSW registration, and from what I can see from the RTA website, if I want to claim a refund I will need:

1) 'Request for refund of NSW registration' form
2) The NSW plate number
3) A copy of the current interstate Certificate of Registration in your name

So that implies I've already registered the car in Victoria.

4) Proof of ID
5) For interstate acquirers, a copy of your Proof of Registration Entitlement which shows the date of acquisition and the vehicle's market value (eg signed transfer details on the back of the NSW Certificate of Registration, or a receipt from the seller).

I don't get this. Do I have to sign NSW transfer papers while I'm up there picking the car up? Or is it just something that the owner and I have to sign?

Any help would be good.

Thanks
