Two drivers. Same car. Same age. Same clean driving history. One lives in Parramatta. The other lives in Orange. The Parramatta driver pays around $200 more for the same CTP green slip.
That gap is not a glitch. SIRA built it into the NSW CTP scheme on purpose, and most drivers have no idea it exists or how it works.
How Does Your Postcode Change Your Green Slip Price?
SIRA divides New South Wales into five rating regions for CTP pricing. Every CTP insurer must use these regions when setting green slip prices.
Insurers cannot use your individual postcode as a separate pricing factor beyond the five zones, but they can still vary your price within a zone based on age, driving history, and vehicle type.
The five regions, ranked from most to least expensive:
- Sydney Metropolitan, highest accident frequency, highest CTP premiums
- Outer Metropolitan, moderate prices, covers fringes of Greater Sydney
- Newcastle and Central Coast, own region due to population density
- Wollongong, separate zone for the Illawarra
- Country, lowest prices across all six licensed insurers
More motor vehicle accidents and more serious injuries per capita in metro areas means more CTP claims. More claims means higher risk. Higher risk means you pay more.
Which Postcodes Fall in Which Zone?
This is the table most CTP sites skip. Here is the full SIRA allocation.
| Rating region | Postcode ranges |
| Metropolitan | 1001–2082, 2084–2234, 2555–2559, 2561–2567, 2745–2749, 2751, 2759–2770 |
| Outer Metropolitan | 2568–2574, 2752, 2754–2755, 2757–2758, 2773–2786 |
| Newcastle & Central Coast | 2250–2309, 2314–2327 |
| Wollongong | 2500–2526, 2530 |
| Country | 2311–2312, 2328–2490, 2527–2529, 2532–2551, 2575–2739, 2787–2899 |
If your postcode sits in the Metro column, you are in the highest‑priced band before any other rating factor kicks in.
What Are the Five Split Postcodes (and Why Do They Matter)?
Five NSW postcodes are split between two rating regions. If you live in one of these postcodes, the suburb you select in the green slip calculator changes your price, sometimes by $100 or more.
| Postcode | Suburbs in higher‑priced zone (Metro) | Suburbs in lower‑priced zone |
| 2083 | All suburbs not listed at right | Mooney Mooney, Cheero Point, Bar Point, Milsons Passage, Cogra Bay → Newcastle & Central Coast |
| 2560 | All suburbs not listed at right | Appin → Outer Metropolitan |
| 2750 | All suburbs not listed at right | Emu Plains (all), Leonay → Outer Metropolitan |
| 2753 | All suburbs not listed at right | Bowen Mountain, Grose Vale, Grose Wold, Yarramundi, Yarramundi Falls → Outer Metropolitan |
| 2756 | All suburbs not listed at right | Colo (all), Ebenezer, Freemans Reach, Glossodia, Lower Portland, Wilberforce (all), Sackville → Outer Metropolitan |
If you live in one of these suburbs and you pick the wrong one in the calculator, you could be quoted a higher price than you should pay. Always select your exact suburb, not just the postcode.
How Big Is the Price Gap Between Metro and Country?
The gap comes from two places: the insurer’s risk‑based premium and the fund levy. Most people only think about the premium. The levy matters too.
Fund levy by zone (motor car, as at January 2026)
| Zone | Fund levy |
| Sydney Metropolitan | $169 |
| Outer Metropolitan | $164 |
| Newcastle / Central Coast | $136 |
| Wollongong | $152 |
| Country | $130 |
A Sydney Metro driver pays $39 more in levy alone before the insurer’s risk premium even starts.

What this looks like for a real driver
Take a 35‑year‑old with a clean licence driving a 2020 Toyota Corolla. Approximate ranges based on publicly available CTP comparison data:
| Factor | Sydney Metro | Country NSW |
| Insurer risk premium (approx.) | ~$470–$550 | ~$310–$390 |
| Fund levy (motor car) | $169 | $130 |
| Approximate total | ~$639–$719 | ~$440–$520 |
| Gap | ~$120–$280+ |
Actual quotes vary by insurer, driving history and vehicle details. Use the green slip calculator for your exact price.
That gap gets wider for younger drivers.
A 21‑year‑old P2 driver in Sydney Metro can see a gap that pushes past $400 compared to the same driver in a Country postcode, based on comparison data, your quote may differ.

Can You Register in a Cheaper Area to Save?
We get asked this a lot. The honest answer is no.
Your CTP green slip must reflect where the vehicle is actually garaged, not a relative’s address two hours away. SIRA and the six licensed insurers use your garaging address to set the rating region.
If you provide a false address, your CTP claim may be refused when you need it most, and you could face penalties for providing false information on a statutory insurance document.
The smarter move: compare all six CTP insurers for your actual postcode. The gap between the cheapest and most expensive insurer inside the same zone can still be $100–$200+. That is real money you can save without bending any rules.

Key Points
- SIRA splits NSW into five rating regions, Metro is the most expensive, Country is the cheapest.
- Five postcodes (2083, 2560, 2750, 2753, 2756) are split between two zones, pick the right suburb in the calculator.
- The fund levy varies by zone: $169 for a motor car in Sydney Metro vs $130 in Country (as at January 2026).
- The bulk of the metro vs country gap comes from the insurer’s risk‑based premium, but the levy adds to it.
- Registering at a false garaging address to get a cheaper zone may result in your CTP claim being refused.
- Compare all six insurers for your actual postcode, the gap between the cheapest and most expensive quote inside your zone can still save you $100–$200+.
People Also Ask About Metro vs Country Prices
These are the questions NSW drivers most often ask about postcode‑based CTP pricing, answered under current SIRA rules.
1. Are green slips cheaper in the country?
Yes. Country NSW sits in the lowest‑priced SIRA rating region. Fewer motor vehicle accidents and fewer serious injury claims in regional areas mean lower risk for CTP insurers, which flows through to cheaper green slip premiums. The fund levy is also lower, $130 for a motor car in Country vs $169 in Sydney Metro.
2. Why do Sydney drivers pay more for CTP?
Sydney Metro has the highest accident frequency and the most CTP claims per registered vehicle in NSW. SIRA groups it into the highest rating region, and every licensed insurer must price accordingly. The fund levy is also the highest in this zone. More crashes, more injuries, more cost.
3. Which postcodes are split between zones?
Five: 2083, 2560, 2750, 2753 and 2756. Each has some suburbs in the Metro zone and others in a lower‑priced zone. Picking the correct suburb in the green slip calculator matters, it can shift your quote by $100+.
4. How much cheaper is country CTP than metro?
For a mid‑30s driver with a clean record and a standard motor car, the gap is roughly $120–$280+, depending on the insurer and fund levy difference. For younger drivers, the gap can push past $400 based on comparison data.
