Fuel seller statistics

Volume of regular and ethanol-blended petrol sold by liable fuel retailers in megalitres

This summary outlines fuel sales by Queensland retailers since the start of the biobased petrol mandate and also provides statistics on biobased diesel sales.

The information is based on reports from fuel sellers to Queensland Treasury for each specific quarter. Queensland Treasury works with fuel sellers to resolve any data quality issues.

Volume of petrol types sold by liable fuel retailers in megalitres

The ethanol percentage for each quarterly period represents the percentage of pure ethanol from the total volume of regular-unleaded petrol (RULP) and RULP blends, such as E10 and E85.

From the January to March 2016 quarter (prior to commencement of the mandate on 1 January 2017), reportable volumes of E10, the most popular ethanol-blended petrol grade, have increased by about 47%.

Petrol sales volumes vary over time. Sales volumes of E10, RULP and PULP petrol grades decreased in the July to September 2025 quarter, compared to the previous quarter.  The ethanol percentage decreased slightly to 2.7%.  While the volumes of both RULP and E10 grades increased slightly in the October to December 2025 quarter, the ethanol percentage remained the same at 2.7%.

Queensland Treasury combines 95RON and 98RON petrol volumes when reporting premium unleaded petrol (PULP) data from fuel retailers.

Petrol availability at retail sites owned or operated by liable fuel retailers

The number of sites offering biobased petrol has remained steady over the past several reporting periods.

In Figure 3 below, the availability of PULP is the combined availability of 95RON and 98RON petrol. Sites selling PULP may be offering only 95RON, only 98RON, or both.

Biodiesel sales achieved by wholesalers

The percentage of biodiesel sold for each quarterly period represents the ratio of B100 (pure unblended biodiesel) from the total volume of diesel sold. The biodiesel percentage during the latest quarter is 0.25% with sales volumes exhibiting significant fluctuation over time.

Biodiesel demand is concentrated among a small number of large commercial customers, particularly in mining, freight and agriculture. As biodiesel remains a small share of the overall diesel market, changes in customer purchasing decisions, feedstock prices, diesel price differentials and regional economic activity can result in large quarter-to-quarter fluctuations in sales volumes.
