What makes up a litre in the capital cities

Of the 198.9 c/L U91 average in the capital cities, crude oil was 86.0 c/L, wholesale 42.2 c/L, excise 47.6 c/L, GST 18.1 c/L and the retail difference 5.0 c/L. Of the 238.9 c/L diesel average in the capital cities, crude oil was 86.0 c/L, wholesale 75.9 c/L, excise 47.6 c/L, GST 21.7 c/L and the retail difference 7.7 c/L. Premium 95 has no terminal gate price of its own, so its breakdown uses the unleaded price and its premium sits in the retail difference. Our retail records begin on 13 April 2026, so earlier periods show the wholesale side only.

How we worked this out

A benchmark illustration using differently weighted period averages, not a matched purchase basket or measured retailer costs. See the same-date retail/TGP comparison separately.

Wholesale is the terminal gate price without GST and excise, less crude oil. GST is one eleventh of the retail price. The retail difference is what is left: the retailer’s costs and margin, without its GST. Bands are rounded so they add up to the retail price.

Retail: FuelRadar station-day averages for the capital cities. Our retail records begin on 13 April 2026, so a period before then has the wholesale side only, and “dearest” and “cheapest” compare the periods since our records began.

Terminal gate price: AIP, national average, carried over weekends. Crude oil: Brent spot (US EIA, via FRED) in Australian dollars, at 158.987 litres a barrel. Excise: ATO, averaged over the period’s days.

Each day’s average against the seven days centred on it, averaged by weekday, so a steady rise or fall does not favour one end of the week. A place needs four of each weekday with prices from five stations or more; a month usually shows the year so far only.

What a 60-litre tank of U91 saved

Filling a 60-litre tank with U91 in Oakford (rural) (WA) rather than Drysdale River (rural) (WA) saved $94.86 on average in the September quarter 2026. At BP Viaduct in Tamworth, the cheapest station we ranked, it cost $17.34 less than at the national average.

Brent: Europe Brent spot price FOB (US Energy Information Administration). Exchange rate: the Federal Reserve’s noon buying rate in New York. Both via FRED, Federal Reserve Bank of St. Louis, averaged over the days each is published; the Australian-dollar figures use each day’s rate. A litre is a barrel divided by 158.987. We use these free benchmarks because the refined-petrol and diesel benchmarks Australian wholesale prices follow (Singapore) are sold by subscription.

Data quality, method and sources

We counted 7,967 in the summed state station counts with eligible prices, over 2,376,817 station–fuel–days across published fuels. Our price records begin on 13 April 2026.

The listed count is the inventory used at build time, not a historical census of every operating station. One station selling two fuels on one day contributes two station–fuel–days. Fuel-specific counts must not be added to obtain a distinct station total. Sum of the included state counts; cross-state station identity is not retained. Each state uses its own saved date window, not a common-day national sample. Calendar days describe the window, not new observations. A dash means the saved edition does not supply that count.

About this edition

How we worked out these figures, and our sources · What this edition can establish

How we worked out these figures, and our sources

What the average measures
Reported station-day prices, not purchases. Each station counts once per day with an eligible price; stations with more covered days contribute more. The mean is not weighted by litres sold and does not measure what the average driver paid.
Which history this uses
This report's station-price records begin on 13 April 2026. The separately published daily city-average series can begin earlier and use different boundaries and carry rules. Compare figures within the same series.
Coverage and carry
National figures combine the station-days in the included state reports. Missing states are excluded, not estimated. An eligible price can be carried forward for up to 30 days. A covered day can therefore contain an earlier reported price. Station-days are observations, not distinct stations. The report does not quantify the share of carried prices or all excluded reports.
Wholesale spreads
Retail less terminal gate price is a gross indicative spread, not profit. It also covers transport, site and operating costs. Brent is a crude-oil benchmark, not a refined petrol or diesel price.
How we average
Each day, every service station counts once at its latest price as of the end of that day. A price is carried forward for at most 30 days, and the average is taken over every station-day in the period, so a station that reported all period counts more than one that reported for a week.
Towns and areas
Each state report ranks its regional towns and its capital’s council areas; this report brings their figures together. Capital cities are their ABS urban areas.
Which prices count
Prices held for checking, prices a station reported as unavailable and implausible prices are left out. A station’s next report ends its previous price.
Coverage
7,967 stations had an eligible input price in the period, including carried prices.
Wholesale, margins and the cost of a litre
The terminal gate price is AIP’s weekday price at the national average; AIP publishes the capital-city terminals only. Weekday prices are carried over weekends, and a period’s price is the mean of its calendar days. The margin is the retail average less the terminal gate price. In the cost of a litre, crude oil is Brent in Australian dollars, wholesale is the terminal gate price without GST and excise less crude oil, excise is the ATO rate averaged over the days, GST is one eleventh of the retail price, and the retail difference is the rest.

What this edition can establish

Not recorded
Carried retail price counts and excluded raw report counts were not retained; their shares are unavailable. The number of stations selling each fuel and litres sold are not recorded, so fuel-market and sales coverage percentages are unavailable.
