Average Weekly Fuel Cost in Australia by Vehicle Type (2026)
Average Australian spends $50–80/week on fuel. Compare costs by vehicle type, state, and distance. Calculate yours with FuelCalc.
The average Australian driver spends between $50 and $80 per week on fuel—roughly $2,600 to $4,160 annually. But your weekly fuel bill depends heavily on three factors: your vehicle's fuel efficiency, how far you drive, and where you live.
In 2026, with unleaded petrol (ULP) averaging $2.20 per litre nationwide and diesel at $2.60/L, fuel costs remain a significant household expense. Whether you're commuting to the city, doing regional runs, or exploring Australia's vast outback, understanding your weekly fuel spend helps you budget better and identify savings opportunities.
This guide breaks down real weekly costs by vehicle type, distance driven, and state—so you can see exactly where you stand.
Below is what you'll spend per week on fuel (ULP $2.20/L) across six common vehicle types and five realistic weekly distance scenarios:
Australia's fuel prices vary significantly by state due to supply chain costs, refinery proximity, and local competition. Here's what a typical mid-size sedan (8.5 L/100km, 300 km/week) costs in each state:
**QLD** $54.40/week — Most competitive pricing in the east; major refineries keep costs down. **NSW** $56.10/week — Sydney metro slightly higher; regional NSW cheaper. **VIC** $57.80/week — Melbourne metro premium; inland regions $1–2/week cheaper. **SA** $53.90/week — Some of Australia's best fuel deals due to intense local competition. **WA** $55.70/week — Perth prices reflect long supply lines; regional WA more expensive. **TAS** $56.10/week — Hobart metro competitive; regional Tasmania 5–10% higher. **NT** $65.30/week — Darwin and regional NT premium (supply limitations). **ACT** $55.20/week — Canberra mid-range; benefits from NSW supply competition.
Over a year, living in NT instead of SA could cost an extra $600 in fuel—worth considering if relocating for work.
**The Melbourne Commuter (Mid-size sedan, 8.5 L/100km)** Drives 250 km/week (5 × 50 km round trip to the office). Weekly cost: $46.75 Annual spend: $2,431
If this driver shifted to 3 days in the office: $28.05/week ($1,459/year)—saving $972 annually.
**The Regional Farmer (Dual-cab ute, 11 L/100km)** Drives 450 km/week (stock checks, town runs, equipment moves). Weekly cost: $109.89 Annual spend: $5,714
Swapping to a more efficient vehicle or consolidating trips could save $800–1,200 yearly.
**The Road Tripper (SUV, 10 L/100km)** Weekend trips and mid-year holidays: 150 km/week average across the year. Weekly cost: $33.00 Annual spend: $1,716
Planning routes efficiently (using [FuelCalc](/)) can save 10–15% on trip costs.
Your weekly pattern—short daily commutes, long regional runs, or occasional road trips—matters more than your vehicle type when budgeting fuel.
The formula is simple:
**(Weekly distance in km ÷ 100) × Fuel consumption (L/100km) × Fuel price ($/L) = Weekly cost**
Example: You drive a Corolla (7 L/100km), cover 350 km/week, and fuel costs $2.20/L. (350 ÷ 100) × 7 × 2.20 = **$53.90/week**
Your vehicle's fuel consumption is listed in the owner's manual or available from the official Green Vehicle Guide (greenvehicleguide.gov.au). Current fuel prices vary by state and postcode—use [FuelCalc](/) to find your local price and instantly calculate trip costs.
For accurate weekly spend, track your actual driving for 4 weeks (commute patterns, errands, weekend trips) and plug the average into the formula. This gives you a realistic budget figure. Want to test different scenarios—longer commutes, road trips, or vehicle swaps? [FuelCalc's calculator](/)) lets you adjust distance, fuel type, vehicle, and price in real-time.
**1. Combine Trips & Plan Routes** Don't make three separate 10 km runs to town; do one 25 km loop. Efficient route planning saves 10–15% on fuel. [FuelCalc](/)) shows the best route and calculates savings instantly.
**2. Maintain Your Vehicle** Under-inflated tyres, a clogged air filter, or worn spark plugs can increase fuel consumption by 5–10%. Servicing costs $200–400 but pays back in fuel savings within weeks.
**3. Switch to Fuel-Efficient Driving** Soft acceleration, steady cruising at 90–100 km/h, and avoiding idling cuts consumption 15–20%. On a sedan doing 300 km/week, that's $8–15/week saved.
**4. Consider Carpooling or WFH Days** Sharing the drive splits fuel costs. Even 2 days/week working from home reduces weekly fuel spend by 40%—saving $15–25/week for most commuters.
**5. Compare Fuel Prices & Fuel Types** Ethanol (E10) is typically 3–5¢/L cheaper than ULP. Diesel is 30–50¢/L pricier but delivers 20–30% better efficiency in larger vehicles. Switching fuel type or shopping around for the cheapest servo saves $2–5/week.
Bundle these tactics and you could cut $15–30 off your weekly bill.
Whether you're spending $25/week or $120/week on fuel depends on your vehicle, distance, and location—but the calculation remains the same. Australian drivers in 2026 can expect to budget between $2,500 and $5,000 annually for fuel, with the middle range around $3,000.
The best way to take control is to know your numbers. Use [FuelCalc](/) to calculate trip costs, compare scenarios, and identify where you can trim expenses. Check the [economy tracker](/economy-tracker) to monitor how fuel prices and your driving habits affect your budget over time.
Save fuel. Save money. Plan smarter.
