On the day you register the vehicle you need to bring your current Victorian driver licence/permit. If you cannot provide this you will need to bring original evidence of identity documents. You must provide:
one primary evidence document (eg. Australian birth certificate or current passport)
one secondary evidence document (eg. Medicare card, credit/account card, student identity card, bank statement)
evidence of residence (if not indicated in the primary or secondary documents)
One of these documents must have your signature on it.
