How car registration is priced in each state
There is no single national rego cost. Every state and territory charges it a different way, which is why the same car can cost hundreds of dollars more to register across a border. The four common building blocks are a fixed registration fee, a vehicle tax that scales with weight or engine size, compulsory injury insurance (CTP), and small admin or plate charges.
NSW and WA price the vehicle tax by the car's tare (unladen) weight. Queensland and Tasmania charge by the number of cylinders, and the Northern Territory by engine size. Victoria is unusual: its TAC injury charge is set by your risk zone, so where you garage the car matters more than the car itself. South Australia bundles a registration fee, levy and CTP together. This tool covers those seven states and territories; for the ACT, use the Access Canberra calculator.
CTP: bundled or bought separately
Compulsory Third Party injury insurance is the biggest swing factor. In Victoria (the TAC charge), WA (Motor Injury Insurance), Tasmania (MAIB) and the NT (MAC), it is government-set and effectively part of your rego bill, so the total is predictable. In NSW and Queensland you buy a CTP greenslip from a private insurer, and the price depends on your car, your record and where you live. For those states we show CTP as a range, not an exact figure, and you should get a live quote before you rely on the number.
Use this to compare, then confirm at the source
This calculator is built to give you a fast, plate-free estimate: handy before you buy, or when weighing up an interstate move. It is an estimate, not a quote. For the exact figure on your car, use your state's official calculator, which we link under each result. Concessions for pensioners, EVs and short-term registration can move the total further.
Frequently asked questions
How much does it cost to register a car in Australia?
It depends on your state and your car. Annual rego for a typical 4-cylinder passenger car runs from roughly $640 to over $1,000 once CTP insurance is included. Victoria and WA sit at the higher end, Tasmania and South Australia at the lower end. This calculator estimates the government fees for seven states and territories so you can see the split.
Which states does this calculator cover?
It covers New South Wales, Queensland, Victoria, Western Australia, South Australia, Tasmania and the Northern Territory, where we can verify the current government fee schedule. NSW, QLD, VIC, WA, TAS and NT are verified against the state authority; SA is a rough estimate because it does not publish a clean component table. The ACT is not included yet because its emissions-based fee is harder to verify, so use the Access Canberra calculator for the ACT.
Why is car registration so different between states?
Each state charges rego its own way. NSW and WA price it by the car's weight, Queensland and Tasmania by the number of cylinders, the NT by engine size, and Victoria by where you live (its risk zones). Compulsory injury insurance (CTP or its equivalent) is bundled in some states and quoted by insurers in others, which is why totals vary so much.
Is CTP insurance included in the rego cost?
It depends on the state. In Victoria (TAC), WA (Motor Injury Insurance), Tasmania (MAIB) and the NT (MAC), the injury premium is government-set and effectively bundled into your rego, so those totals are complete. In NSW and Queensland you buy a CTP greenslip from a private insurer, so we show it as a range rather than an exact figure. South Australia is shown as a bundled rough estimate.
How much is rego in VIC for 12 months?
For 2025-26, a standard Melbourne metro car pays about $343 in VicRoads registration fee plus a TAC charge of roughly $587 (high-risk zone, includes GST and duty), so around $930 for 12 months. Rural low-risk zones pay less because the TAC charge drops to about $458.
How much will my rego be in QLD?
Queensland charges by cylinders. From 1 July 2026 a 4-cylinder car is $385.45 registration plus a $67.25 traffic improvement fee, then CTP of about $412 to $425, so roughly $865 to $878 for 12 months. A 6-cylinder car pays $610.30 registration instead.
Do I need my number plate to use this calculator?
No. The official state calculators usually ask for your plate or client number. This tool estimates from your state and a couple of details about the car, so you can check the cost before you buy or when comparing states.
This tool is a guide, not financial or registration advice. Figures are estimates of government fees; confirm the exact cost with your state transport or revenue authority.
