Transport Costs in Australia 2026 — Why Your Car and Commute Costs Are Rising Fast
Transport is now the fastest-rising cost category in the Australian Consumer Price Index — overtaking housing and food in the 12 months to March 2026. The spike was driven by a sudden and dramatic increase in fuel prices following global oil market disruption, but the underlying trend in transport costs had been building well before March’s surge.
Here is a complete breakdown of transport costs in Australia in 2026, based on the most recent data from the Australian Bureau of Statistics.
Transport Costs in the CPI — The March 2026 Numbers
Transport rose 8.9 per cent in the 12 months to March 2026, compared to a small fall in the 12 months to February. The monthly CPI movement for March was driven by Transport which rose 9.2 per cent, due primarily to a 32.8 per cent monthly increase in automotive fuel prices.
To put that in context — Transport was the second-largest contributor to annual inflation in March 2026, behind only Housing. The largest contributors to annual inflation were Housing at 6.5 per cent, Transport at 8.9 per cent, and Food and non-alcoholic beverages at 3.1 per cent.
CPI annual movement by major group — March 2026:
| Category | Annual Change |
|---|---|
| Transport | +8.9% |
| Housing | +6.5% |
| Clothing & Footwear | +7.1% |
| Education | +4.8% |
| Alcohol & Tobacco | +4.4% |
| Food & Non-Alcoholic Beverages | +3.1% |
| Health | +3.0% |
| Insurance & Financial Services | +2.8% |
| Recreation & Culture | +2.8% |
| Communications | +1.4% |
| Furnishings & Household Equipment | +1.4% |

Transport’s 8.9 per cent annual rise is not just a March aberration. It represents the cumulative effect of fuel price volatility, rising new vehicle costs, and the ongoing removal of government subsidies that had temporarily kept transport costs lower than the underlying market rate.
What Drove the March 2026 Fuel Price Spike
Conflict in the Middle East and interruption of oil passing through the Strait of Hormuz reduced the supply of oil exports from the region, causing significant volatility in the global price of oil and higher petrol and diesel prices across the world.
The impact in Australia was severe and fast. Average prices for regular unleaded petrol rose 33 per cent, increasing from 171 cents per litre in February to an average price of 228 cents per litre in March. Premium unleaded rose 30 per cent to 250 cents per litre. Diesel rose 41 per cent from 181 cents per litre in February to 256 cents per litre in March.
Prices in March were 10.7 per cent higher than the previous peak in September 2023 — and the 32.8 per cent monthly increase was the largest since the series began in 2017.
The Government responded by halving the fuel excise from 1 April 2026. The March CPI data predates that change — the April figure will be the first to capture whether the excise cut has flowed through to pump prices.

How Transport Costs Hit Household Budgets
Household spending rose 1.6 per cent in March 2026, driven by a 5.1 per cent rise in transport costs as fuel prices climbed in response to the conflict in the Middle East. Fuel prices spiked during the first week of March, with prices peaking at the end of March as motorists made smaller, more frequent trips to the petrol station.
Strength in public transport spending also contributed, likely reflecting some households switching away from private vehicles in response to rising fuel costs.
For a household driving 15,000 kilometres per year in an average petrol car consuming 10 litres per 100km, the shift from 171 cents per litre to 228 cents per litre translates to an additional $855 in annual fuel costs — on top of whatever was already being paid at the start of the year.
That figure assumes prices stay at March levels. If they moderate following the fuel excise cut, the annual impact will be lower. But the March spike was large enough to remain significant even if partially reversed.
The Broader Transport Cost Picture
Fuel is the most volatile component of transport costs, but it is not the only one. Several other factors have been pushing transport costs higher across 2025 and into 2026.
New vehicle prices. The cost of new vehicles rose substantially during the global supply chain disruptions of 2021–2023 and have not fully unwound. Automotive fuel has a weight of 3.5 per cent of the CPI basket, but vehicle purchase costs, insurance, registration, and maintenance make transport one of the largest spending categories in most Australian household budgets.
Vehicle insurance. Insurance and financial services rose 2.8 per cent annually to March 2026, but motor vehicle insurance has been rising faster than that within the category. Higher vehicle replacement costs, more expensive parts, and increased claims frequency have pushed premiums up consistently across 2024 and 2025.
Road tolls. In Sydney and Melbourne, toll costs have risen through CPI-linked price escalation clauses in toll road concession agreements. For Sydney commuters using major corridors like the M2, M7, or Eastern Distributor, annual toll costs can exceed $3,000 to $4,000.
Public transport fares. State governments set public transport fares and have increased them at varying rates. Sydney’s Opal network and Melbourne’s Myki system both have regular fare adjustments. However, several states have maintained concessional or capped fares — Queensland extended its 50 cent flat fare through parts of 2025-26, significantly reducing commuter costs for eligible users in that state.
Transport Costs Relative to Wages
The scale of transport cost increases needs to be understood relative to what wages are actually doing. Annual wage growth to November 2025 was 3.8 per cent — lower than the 4.5 per cent seen to May 2025.
Transport costs rising at 8.9 per cent annually against wage growth of 3.8 per cent means the real cost of transport — its cost relative to purchasing power — is increasing significantly. A worker on the median salary who does not receive above-award pay increases is falling behind on transport costs at roughly 5 percentage points per year.
For context on what Australian workers earn and how wages compare to rising costs, see our average salary in Australia 2026 guide.
What the Fuel Excise Cut Means
The federal government halved the fuel excise from 1 April 2026 — the same policy tool used during the 2022 cost of living squeeze. The increase in March was the largest monthly increase since the series began in 2017, reflecting the impact of the conflict in the Middle East on fuel prices, and predated the halving of the fuel excise on 1 April.
The fuel excise cut reduces the tax component of fuel prices, which should translate to lower pump prices — but only if retailers pass the saving through. In 2022, the ACCC monitored whether retailers passed on the excise reduction. Whether the same scrutiny applies in 2026 will affect how much relief households actually see at the pump.
The April 2026 CPI data — due in late May 2026 — will be the first measure of whether pump prices have fallen following the excise cut. The RBA will be watching this data closely as part of its June 2026 interest rate decision. For more on how the RBA is responding to the current inflation environment, see our RBA interest rates 2026 guide.
How to Reduce Your Transport Costs in 2026
With transport costs running at near-record levels, the practical question for households is what can actually be done.
Check fuel price apps. Apps like GasBuddy and state government fuel price websites publish real-time prices from service stations across your area. In most capital cities, price differences of 15 to 30 cents per litre between nearby stations are common — especially mid-week when prices are typically lower in cities following the weekly price cycle.
Switch to off-peak public transport where available. Several states offer off-peak discounts on public transport smart card systems. Sydney’s Opal card charges lower fares before 7am and after 9am on weekdays and all day on weekends. If your commute is flexible, adjusting the timing can reduce weekly transport costs meaningfully.
Reassess vehicle running costs. For households with two cars, the question of whether both are genuinely necessary at current fuel prices is worth revisiting. Fixed costs — insurance, registration, depreciation — apply regardless of how much the vehicle is driven.
Consider the fuel efficiency of your next vehicle. The shift from 171 cents per litre to 228 cents per litre has changed the economics of vehicle choice. A vehicle consuming 7 litres per 100km versus one consuming 11 litres per 100km saves approximately $1,140 annually at current fuel prices over 15,000 kilometres — a difference that compounds over the vehicle’s lifetime.
Frequently Asked Questions
Why did Australian petrol prices spike in March 2026?
The conflict in the Middle East disrupted oil supply through the Strait of Hormuz, causing significant volatility in global oil prices that flowed through to Australian pump prices. Regular unleaded petrol rose from 171 cents per litre in February to 228 cents per litre in March — a 33 per cent increase in a single month.
Has the fuel excise cut brought prices down?
The federal government halved the fuel excise from 1 April 2026. The March CPI data predates this change. Whether retailers have passed the saving through to pump prices will be visible in the April 2026 CPI release, due in late May 2026.
Which is cheaper — driving or public transport in Australia?
For most urban commutes, public transport is significantly cheaper than driving once you account for fuel, parking, tolls, insurance, registration, and depreciation. The cost advantage of public transport grows substantially when fuel prices are elevated. The calculation changes in outer suburban and regional areas where public transport options are limited or infrequent.
Will transport costs come down in 2026?
The trajectory depends primarily on global oil markets and whether the fuel excise cut is passed through to consumers. If the Middle East conflict stabilises and oil supply recovers, fuel prices should moderate from March’s peak. However, other components of transport costs — insurance, vehicle prices, tolls — are unlikely to reverse. The outlook for overall transport costs in 2026 remains elevated relative to pre-2024 levels.
How much does transport cost the average Australian household per year?
Based on ABS Household Expenditure Survey data, transport is typically the second or third largest household expenditure category after housing and food. For a household with one car and a regular commute, annual transport costs including fuel, insurance, registration, tolls, and public transport can range from $8,000 to $15,000 depending on location, vehicle type, and commute distance.
Key Takeaways — Transport Costs Australia 2026
Transport costs rose 8.9 per cent annually to March 2026 — the fastest-rising major CPI category. The March spike was driven by a 32.8 per cent monthly increase in automotive fuel prices following global oil market disruption linked to the Middle East conflict. Regular unleaded petrol reached 228 cents per litre in March, a 33 per cent increase from February’s 171 cents per litre. Diesel rose 41 per cent in the same period. The government halved the fuel excise from 1 April 2026 — whether this has reduced pump prices will be visible in the April CPI release. For households, transport is now one of the fastest-growing items in the budget, rising well ahead of wage growth of 3.8 per cent annually.
