National averages

The mean of every station's current report for the grade (a price reported within the last 14 days), after price and freshness checks. A figure is called national only when every state and territory reports; otherwise the reporting states are named. Dated by the time FuelRadar Australia last updated the prices.

  1. 240.3cU91 average

    As of 1 November 2026, the national average U91 price in Australia was 240.3 c/L across 6,396 stations.

  2. 282.1cDiesel average

    As of 1 November 2026, the national average diesel price in Australia was 282.1 c/L across 3,797 stations.

Price gaps between fuel grades

Each gap is the difference between two grades' national averages of current station reports. Every station reporting a grade counts toward that grade's average, so a gap compares two national averages, not the same stations.

Averages in c/L of current station reports within the area shown from each city centre. The cheapest day and cycle length come from each city's 4:40 am daily average; "No regular cycle" means fewer than three measured cycles or no retail price cycle.

Cheapest day of the week

From each capital's U91 city daily average (the 4:40 am figure). Each day is compared with the mean of the seven days centred on it, so the price trend does not decide the answer. A day is named only when it is the week's lowest in most full weeks, over at least 6 full weeks, with at least 2.0 c/L between the cheapest and dearest day.

  1. WednesdayPerth

    Wednesday was the cheapest day to buy U91 in Perth in each of the 11 full weeks to 1 November 2026, on average 6.9 c/L below the seven days around it; Thursday was the dearest.

  2. No set dayseven capitals

    No weekday was consistently the cheapest for U91 in Sydney, Melbourne, Brisbane, Adelaide, Canberra, Darwin and Hobart over the last 11 full weeks to 31 October 2026, so where prices sit in the cycle matters more than the day.

Price cycle length

Cycles are measured from each capital's U91 city daily average over the last year: a cycle runs from one low to the next. Figures are medians of the last 12 completed cycles, shown only for a capital with at least 3 and a regular retail cycle.

  1. 7 days

    As of 1 November 2026, Perth's U91 price cycle lasted a median of 7 days over its last 12 cycles; prices rose a median of 14.3 c/L from the low to the peak within 1 day.

About these facts

  1. Where the prices come from

    FuelRadar Australia reads prices from official state fuel price schemes and data feeds, plus retailer and station reports. FuelRadar Australia is an independent service, not a government one.

  2. How they are checked

    Fuel grades, brands and stations are matched consistently, and invalid or placeholder prices are removed before any average is taken. A figure whose data is missing is left out, never estimated.

  3. How to quote them

    Quote a fact with its date and credit FuelRadar Australia (fuelradar.com.au). Each fact's copy button adds the source line. Prices change every day, so a fact is true for the date it carries.
