Car Registration Cost by State in Australia (2026): Same 4-Cylinder Car Registered in NSW vs QLD vs VIC vs WA vs SA
Take one ordinary car — a 1,400 kg, 4-cylinder sedan like a Corolla or i30 — and register it in each state, and the total bill swings from roughly $630 a year in Tasmania to over $1,000 in New South Wales and the ACT. The gap isn't random: each state calculates the base fee differently (by weight, by cylinders, by emissions, or a flat rate), and — the part that trips everyone up — some states bundle your compulsory injury insurance (CTP) into the rego total while others make you buy it separately, so the "registration fee" you see quoted is not comparable across borders.
The apples-to-apples comparison
To compare fairly, we hold the car constant: a private-use, petrol, 4-cylinder sedan with a tare mass of about 1,400 kg (a very common family-car weight), registered to a metropolitan / higher-risk address for a full 12 months. Every figure below comes from the official state authority for the 2025–26 financial year (fees generally reset on 1 July). Where a state lets you choose your own injury-insurance premium, we show an indicative metro figure — your actual quote depends on your insurer, postcode and record.
| State | How base fee is set | Base rego + tax/levies | CTP / injury insurance | Indicative all-in (12 mo, metro) |
|---|---|---|---|---|
| TAS | Flat motor tax by cylinders | ~$254 (motor tax $166 + rego fee $87.86 + levies) | Included — MAIB $318 | ~$630–$660 |
| SA | Cylinders + location | Registration + levies | Bundled on notice; you pick insurer | ~$675 metro (~$575 country) |
| WA | Weight (per 100 kg tare) | Licence fee ~$401 (14 × $28.64) | Included — Motor Injury Insurance | ~$850–$900 |
| VIC | Flat rego fee + zoned insurance | Registration fee ~$343 (20.42 fee units × $16.81) | Included — TAC charge (zoned) | ~$860 (Zone 1), higher in outer zones |
| QLD | Cylinders (4-cyl bracket) | Rego fee $385.45 + traffic improvement fee $67.25 | Included — CTP $411.80–$424.80 | ~$865–$878 |
| ACT | Emissions rating (since Jul 2024) | Emissions-based rego fee + levies | MAI policy; you pick insurer | ~$950–$1,050 (model-dependent) |
| NSW | Weight (motor vehicle tax) | Rego $84 + vehicle tax $391 = $475 | Separate — Green Slip (CTP) ~$550–$680 metro | ~$1,025–$1,155 |
Figures as of the 2025–26 financial year / 2026, drawn from each state's official schedule (linked below). "All-in" totals for NSW, SA and ACT include an indicative metro injury-insurance premium because you choose your own insurer there — get a live quote before you rely on the number. Amounts exclude one-off costs like stamp duty and plate fees on a brand-new registration, and any pensioner/concession discounts.
Why the totals differ: four completely different formulas
There is no national registration fee. Each state parliament sets its own, and they don't even agree on what to charge for. That's the real reason the same car costs wildly different amounts:
By weight — NSW and WA
NSW charges a small flat registration fee ($84) plus a motor vehicle tax that steps up with your car's tare weight. A private car in the 1,155–1,504 kg bracket pays $391 in tax, so $475 before the Green Slip (NSW Government). WA is the purest weight formula: a licence fee of $28.64 per 100 kg of tare, so a 1,400 kg car pays 14 × $28.64 = $400.96, plus a recording fee, admin fee and Motor Injury Insurance (Transport WA). Heavier car = higher rego in both states.
By cylinders — QLD, SA and TAS
Queensland puts your car in a bracket by number of cylinders: a 4-cylinder private car pays a $385.45 registration fee + a $67.25 traffic improvement fee + CTP, for a total of $864.50–$877.50 (qld.gov.au). Move up to a 6-cylinder and the fee jumps. SA and Tasmania also band by cylinders (and, in SA, by metro vs country). In Tasmania a 4-cylinder car's motor tax is $166, on top of an $87.86 registration fee and the MAIB insurance premium (Transport Tasmania).
Flat fee + zoned insurance — VIC
Victoria is the odd one out: the registration fee itself is a flat amount for almost all light passenger cars — 20.42 fee units at $16.81 per unit = $343.26 for 2025–26 (VicRoads). Weight and cylinders don't change it. What does change your bill is the TAC charge — your compulsory accident insurance — which is priced by risk zone based on where you garage the car. Inner-metro Zone 1 is cheapest; outer and regional zones cost more (TAC). Yes, in Victoria the country driver often pays more, the opposite of SA.
By emissions — the ACT
Since July 2024 the ACT prices registration on your car's emissions rating, not its weight. A cleaner, lower-emitting car pays less; a thirsty petrol sedan pays more. Layered on top are the Lifetime Care and Support Levy ($110.40 for 2025–26), the Road Safety Contribution Levy ($3.20) and the Motor Accident Levy ($14), plus your chosen Motor Accident Injuries (MAI) insurance policy (Access Canberra). Because it's model-specific, the only reliable ACT number is the one the official calculator gives you.
Priya's 2019 Toyota Corolla — 4-cylinder, tare mass ~1,400 kg, private use, clean driving record. She's weighing up a move from Sydney to Brisbane and wants to know what rego actually costs in each. Both are metro addresses, both 12-month renewals, no concessions.
New South Wales (Sydney):
- Registration fee (flat): $84.00
- Motor vehicle tax, 1,155–1,504 kg private bracket: $391.00
- Subtotal on the RMS renewal: $475.00
- CTP Green Slip — a separate purchase from a licensed insurer, ~$600 for a clean-record Sydney sedan
- Priya's true NSW cost ≈ $1,075/year
Queensland (Brisbane):
- Registration fee, 4-cylinder bracket: $385.45
- Traffic improvement fee: $67.25
- CTP — included on the same notice: ~$418 (mid of the $411.80–$424.80 range)
- Priya's true QLD cost ≈ $870/year — one payment, nothing else to buy
The lesson: NSW's renewal notice reads $475 and Queensland's reads ~$870, so at a glance NSW looks almost half the price. But once Priya adds the Green Slip she's legally required to buy, NSW is about $205 a year more expensive for the identical car. The headline fee lied; the all-in figure told the truth.
Cheapest and most expensive on the same car
On an all-in basis for our 1,400 kg 4-cylinder metro sedan:
- Cheapest: Tasmania (~$630–$660), thanks to a low $166 motor tax and a modest MAIB premium — and South Australia's country rate (~$575) is lower still if you live regionally.
- Mid-pack: SA metro, WA, VIC (Zone 1) and QLD, clustered between roughly $675 and $880. These four bundle injury insurance, so the number you see is close to the number you pay.
- Most expensive: NSW and the ACT (~$1,000+). NSW because the separately-bought Green Slip pushes a cheap-looking $475 notice past four figures; the ACT because emissions pricing plus its levy stack lands high for a conventional petrol car.
Two honest caveats. First, zones and location move these numbers: a VIC outer-suburban or regional postcode can add a couple of hundred dollars via the TAC charge, while an SA or NSW regional address cuts the cost. Second, your CTP premium is personal in NSW, SA and the ACT — age, claims history and even the insurer you pick change it — so treat those totals as a starting estimate and get a live quote.
You must register where you actually live (the garaging-address rule)
Seeing that Tasmania or country SA is cheaper, plenty of people wonder if they can just register the car "at a mate's place" interstate. You can't. Every state requires you to register a vehicle in the jurisdiction where it is normally garaged and used — the address where it sleeps most nights — and to hold a driver licence for the state you reside in. It's not a paperwork technicality:
- Your CTP / injury insurance is priced on the garaging postcode. Give a false address and, in the event of a serious claim, the insurer can investigate and potentially reduce or dispute cover — leaving you personally exposed to injury liability that can run to hundreds of thousands of dollars.
- It's a false declaration. Registering against an address where the car isn't kept is providing false information to the registration authority, which carries fines and possible cancellation of registration.
- Genuine moves are fine — and required. If you actually relocate interstate, you generally have a set window (commonly a few weeks to three months, depending on the state) to transfer your registration and licence to your new home state. That's not a loophole; it's the correct process.
So the practical takeaway on cost: you don't get to shop states for the cheapest rego. You pay what your real home state charges. The comparison above is most useful when you're genuinely moving, buying interstate, or budgeting before a relocation.
- Same car, ~$400+ spread. A 1,400 kg 4-cylinder sedan runs ~$630 all-in in Tasmania and $1,000+ in NSW and the ACT.
- Never compare headline "registration fees." QLD, VIC, WA and TAS bundle compulsory injury insurance; NSW, SA and the ACT don't. Compare the all-in figure.
- Four different formulas: weight (NSW, WA), cylinders (QLD, SA, TAS), flat fee + zoned insurance (VIC), emissions (ACT).
- NSW is the classic trap: a $475 notice becomes ~$1,075 once you buy the separate Green Slip.
- You must register where the car lives. Chasing a cheaper state by using a false address risks your insurance cover and is a false declaration.

Frequently asked questions
Which Australian state has the cheapest car registration in 2026?
For a typical 1,400 kg 4-cylinder private sedan compared on an all-in basis (registration plus compulsory injury insurance), Tasmania is generally the cheapest at roughly $630–$660 a year, helped by a low $166 motor tax and modest MAIB premium. South Australia's country/regional rate (~$575) can be lower still if you live outside the metro area. Always confirm with the official state calculator for your exact car and postcode.
Why does NSW registration look so cheap but end up expensive?
Because NSW quotes registration and CTP separately. The registration notice for a mid-weight car is about $475 (an $84 fee plus $391 motor vehicle tax), but you must separately buy a compulsory CTP "Green Slip" from a licensed insurer — typically ~$550–$680 for a metropolitan Sydney sedan. Add them and the true annual cost is around $1,025–$1,155, making NSW one of the most expensive states once everything is counted.
Is CTP insurance included in the registration price?
It depends on the state. Queensland, Victoria, Western Australia and Tasmania include compulsory injury insurance (CTP / TAC / MII / MAIB) in the total you pay at renewal. New South Wales, South Australia and the ACT treat it as a policy you buy — in NSW it's fully separate (the Green Slip), while in SA and the ACT it's collected on the same notice but you choose the insurer. That difference is the main reason headline "rego fees" aren't comparable between states.
How is the base registration fee calculated in each state?
There are four approaches. Weight (tare mass): NSW and WA — heavier cars pay more (WA charges $28.64 per 100 kg). Cylinders: QLD, SA and TAS band cars by engine cylinder count. Flat fee plus zoned insurance: Victoria charges a flat registration fee (~$343 for 2025–26) and varies the cost through the location-based TAC charge. Emissions: the ACT has priced registration on a car's emissions rating since July 2024.
Can I register my car in a cheaper state to save money?
No. You must register a vehicle in the state where it is normally garaged and used, and hold a licence for the state you live in. Registering at an interstate address where the car isn't kept is a false declaration (subject to fines and possible cancellation) and can void or reduce your compulsory injury cover, because your premium is priced on the real garaging postcode. If you genuinely move interstate, you transfer your registration and licence within the required timeframe.
Do these figures include stamp duty and concessions?
No. The comparison shows ongoing 12-month renewal costs only. A brand-new registration or a transfer usually also attracts one-off vehicle stamp duty (based on the purchase price/value) and plate fees, which can add hundreds to thousands of dollars once. Separately, pensioners, seniors and some concession-card holders qualify for reduced or waived registration in several states — check your state authority for eligibility.
