How registration in Australia is calculated
Australia has no CO2 car tax; the recurring cost is annual registration (rego). It combines a base fee, a motor-vehicle tax that rises with tare weight, and compulsory third-party insurance (CTP).
Rates and CTP differ between NSW, Victoria, Queensland and other states. The calculator uses an illustrative NSW-style structure. Estimate, not advice.
