Second-hand vehicles (interstate)
To establish registration for a second-hand vehicle purchased interstate, you will need to go to a motor registry and provide:

Proof of your identity (see related link above right) or, if registering the vehicle in the name of a company, proof of company name and the ACN/ARBN number.
Proof of acquisition (eg a receipt for purchase of the vehicle, certificate of registration signed by the previous registered operator/s of the vehicle, or the previous certificate of registration in the same name if coming from interstate).
Proof of your residential address (see related link above right).
A valid Compulsory Third Party insurance policy – also known as a green slip – with the number plate section blank (not required for trailers).
An inspection report – also known as a blue slip – from an Authorised Unregistered Vehicle Inspection Station (AUVIS). If there is no AUVIS in your area, you can get a pink slip from an Authorised Inspection Station (AIS) instead of the blue slip.
Your interstate number plates – you'll have to surrender your interstate plates before you'll be given NSW plates.
Evidence of eligibility for any concession (see related links to Pensioner concessions and Apprentice registration rebate above right).
A completed Application for Registration form.
Payment for registration, including stamp duty (3% of the vehicle's purchase price, 5% if more than $45,000) and applicable number plate fee.
All second-hand vehicles requesting establishment of registration (including interstate and imported vehicles) may be selected for an additional inspection by the RTA's vehicle identity unit. You will be notified at the time of registration if you are selected.
