Yagoona E10 Falls 17 Cents as Sydney and Brisbane Petrol Cycles Head in Opposite Directions

According to pricing data collected on the morning of Tuesday 21st Jul 2026, the country's two biggest E10 markets have parted company. As of 8:04am AEST, E10 in Yagoona in Sydney's south west has fallen 17.4 cents to an average of 170.5 cents per litre, while Eight Mile Plains on Brisbane's southside has climbed 21.7 cents to 170.6. Two suburbs more than 700 kilometres apart, separated by one tenth of a cent, and travelling in completely opposite directions.

The Yagoona numbers

Six stations in Yagoona were averaging 187.9 cents per litre for E10 at the previous reading. This morning that figure is 170.5, a fall of 17.4 cents and the largest for any fuel on today's national movers list.

The timing matters here. When I analysed the Sydney market in early July, Bexley had just jumped 17.1 cents in a single reset as the city entered the expensive half of its price cycle. Historical data suggests the discount phase then plays out over two to three weeks as stations compete their way back down, and Yagoona's fall this morning fits the back end of exactly that pattern. What went up in Bexley in the first week of July is now coming down in the south west in the third.

For the roughly one in five motorists who choose ethanol blend fuel, the difference is real money. Filling a 50 litre tank in Yagoona this morning costs about $8.70 less than it did at the last reading. You can check current E10 prices for the rest of the country on our dedicated fuel page.

Brisbane tells the opposite story

In Eight Mile Plains the picture flips. E10 across the suburb's six stations climbed 21.7 cents to 170.6, unleaded petrol rose 22.7 cents to 172.9, and Premium 98 posted the largest rise on today's list, up 29.7 cents to 197.3. When every grade moves together like this, the explanation is almost always a cycle reset rather than anything specific to one fuel.

Nor is the pattern confined to Brisbane's southside. Down the motorway in Southport, E10 rose 10.4 cents to 168.3, which suggests the upward reset is working through south east Queensland more broadly.

Same price, very different value

On this morning's numbers, Yagoona and Eight Mile Plains are effectively at the same price. The value on offer could hardly be more different. A Yagoona driver is buying into a falling market, while an Eight Mile Plains driver is buying near the top of a fresh reset. A Brisbane motorist who filled up at the previous reading of 148.9 saved around $10.85 on a 50 litre tank compared with today. The equivalent Sydney driver was better off waiting.

This is the whole case for cycle timing, and it is why our best time to fill up guide tracks each capital separately. The cycles in NSW and Queensland are not synchronised, and this week is about as clean a demonstration as the data ever provides.

Diesel quietly eases across NSW

While the petrol cycles grab the headlines, NSW diesel continues its slow drift lower, easing 1.1 cents to a statewide average of 214.8 cents across 1,356 stations. In Granville in Sydney's west, all three servos are sitting at exactly 199.5, a spread of zero that points to tight local competition. Regional centres remain the value leaders: Grenfell has diesel from 191.9, and East Wagga Wagga, which I covered earlier this month when it claimed the cheapest diesel in the country, is still holding all three of its stations at 194.5.

For motorists willing to shop around, the lesson this week is that the same fuel at the same price can be very different value depending on where your city sits in its cycle. Sydney's E10 buyers should enjoy the falls while they last. Brisbane's should fill up before the reset finishes working through.
