The Real Annual Cost of Running a Car in Australia: State-by-State Honest Numbers

"Just $35 a week to run." You see it in finance ads for new cars. The number is fuel cost only, often based on absurd low-mileage assumptions, and ignores everything else that actually drains your bank account when you own a car in Australia.

The honest number for owning a typical mid-size car in Australia, including everything, is usually $9,000-$14,000 per year. State-by-state varies significantly because compulsory insurance (CTP) and registration costs differ enormously across the eight jurisdictions.

Here is the real breakdown for 2025-2026, with honest state-by-state numbers.

The 7 Real Cost Categories

Every Aussie car owner pays for some combination of:

1. Registration ("rego") — annual renewal fee paid to your state government
2. Compulsory Third Party insurance (CTP) — mandatory injury insurance, charged with rego in most states (separate in NSW)
3. Comprehensive (or third-party property) insurance — optional but strongly recommended
4. Fuel — petrol, diesel or electricity
5. Servicing and maintenance — annual log book service plus tyres, wipers, batteries
6. Repairs — unscheduled (averaged across years)
7. Depreciation — value lost as the car ages (the big silent cost most owners forget)

State-by-State: Rego + CTP for a Typical Family Car

Indicative annual rego + CTP for a 4-cylinder petrol passenger car (no concessions):

Big takeaways:

• NSW + ACT are the most expensive for combined rego + CTP, mostly because of higher CTP premiums
• Tasmania is cheapest, often by a margin of $400-$700/year vs NSW/ACT
• Victoria includes CTP in rego, simplifying comparison but the total is still mid-range
• Concession-eligible owners (pensioners, low-income, vets) get significant discounts in most states — check eligibility

Comprehensive Insurance — The Wildcard

Comprehensive insurance varies enormously based on age, location, vehicle, claims history. Indicative annual premiums for a 35-year-old driver with clean record:

Premium rises for: under-25 or over-70 drivers, performance models, theft-prone vehicles (some Range Rovers, Lexus models), high-claim postcodes (Sydney west, Melbourne north, Gold Coast).

Fuel — The Real Numbers

Average Aussie driver does about 13,000 km/year (per BITRE data).

Servicing & Maintenance — Annual Average

This excludes major repairs (timing belts every 100,000-150,000 km, transmission services, suspension overhauls). Budget an extra $400-$800/year averaged across the life of the vehicle for these.

Depreciation — The Silent Big Cost

The cost most owners ignore. A new $45,000 car loses about $11,000-$15,000 in its first 3 years (25-35%). That is $3,500-$5,000 per year in depreciation alone.

Some categories depreciate slower: Toyota HiLux, LandCruiser, Mazda CX-5 hold value better than equivalents. European luxury (BMW, Mercedes, Audi) and EVs (in 2024-25 particularly) depreciate faster.

If you keep the car 10+ years, annual depreciation drops dramatically (most loss has already happened). If you change every 3-5 years, this is your biggest cost.

Putting It All Together — Worked Examples

Example 1: Sydney resident, 2018 Mazda CX-5, owned outright

• Rego + CTP: $1,000
• Comprehensive insurance: $1,100
• Fuel (13,000 km): $1,950
• Service + maintenance: $900
• Repairs (averaged): $400
• Depreciation (year 7-8): $2,500
• Annual total: $7,850

Example 2: Brisbane resident, 2022 Ford Ranger, financed

• Rego + CTP: $760
• Comprehensive insurance: $1,300
• Fuel (13,000 km diesel): $2,300
• Service + maintenance: $1,100
• Repairs (averaged): $300
• Depreciation (year 3-4): $4,000
• Finance interest (estimated): $1,800
• Annual total: $11,560

Example 3: Hobart resident, 2015 Toyota Corolla, owned outright

• Rego + CTP: $565
• Comprehensive insurance: $750
• Fuel (13,000 km): $1,440
• Service + maintenance: $700
• Repairs (averaged): $500
• Depreciation (year 10-11): $1,200
• Annual total: $5,155

Where the Real Savings Live

• Older car, owned outright beats newer car on finance — by far. Depreciation + interest dominate other costs.
• State of residence matters — Tasmania vs NSW for the same car can differ by $1,500/year in rego+CTP+insurance combined
• Vehicle category matters — a Corolla costs less than half what a HiLux Premium does annually, with the same driver and same kilometres
• Insurance shopping annually — biggest single lever most owners can pull. $200-$600/year savings is realistic.
