so, in Victoria, when you take your ICV for full reg you are considered a new car, and you need to pay stamp duty on the value of the car. Stamp duty and rego costs are of course highly variable around the country.

Luxury Car Tax is applied at point of sale, not point of registration, so LCT does not apply to an ICV. Even if VicRoads/you determine that your ICV has a "value" of 200K and you pay stamp duty on that amount, LCT does not even exist in a VicRoads system.

I have no f'in idea what the state of play is in QLD, but I'm sure the LCT part will be the same.
