Damn right you do if you're in Victoria or Queensland. A lot of bureaucracy is involved in car registration or rego, as it's known Down Under. Rego includes third-party compulsory insurance and stamp duty. In subsequent years, your rego fee will include the motor vehicle tax and the third-party compulsory insurance.t's nice to think that if you're buying your car in October with a May registration expiration that you're getting 7 months free registration. That's not altogether true. The seller will probably factor in the unused registration into the selling price of the car.
