Twelve Geelong Servos Match Unleaded at Exactly 228.3 While Armstrong Creek Pays 234.9

Twelve Geelong Servos Match Unleaded at Exactly 228.3 While Armstrong Creek Pays 234.9

The unleaded figures pulled at 8:15am AEST on 30th Sep 2026 put the average across 49 servos within 15 kilometres of central Geelong at 230.5 cents a litre. Twelve of those servos are charging exactly the same price, 228.3, down to the tenth of a cent. A few kilometres south, in the growth suburbs, motorists are paying 234.9 or more. The line between the two deserves closer scrutiny.

One price, twelve servos

APCO sets the number. All eight of its Geelong sites, from Lara in the north to Mount Duneed in the south, list unleaded at 228.3, and APCO Barwon Heads is on the same figure.

More interesting is who else has matched it. BP Grovedale, across Torquay Road from APCO Grovedale, is at 228.3. So are Liberty and Belmont Petroleum in Belmont, and 7-Eleven Waurn Ponds on Colac Road. A price ending in .3 is unusual. When four different operators land on the same tenth of a cent, it suggests they are all watching one benchmark and matching it.

Price matching is legal, and it often works in the motorist's favour because it pulls dearer sites down. It does leave a fair question, though. Why does the matching stop where it does?

The Armstrong Creek gap

Head into the southern growth corridor and the matching falls away. Both 7-Eleven servos in Armstrong Creek and the 7-Eleven in Charlemont list unleaded at 234.9. Ampol Foodary Armstrong Creek lifted from 234.9 to 239.9 on Tuesday evening and is now the dearest servo in the Geelong sample.

Barwon Heads Road is the clearest example. Liberty Belmont, towards the northern end, is at 228.3. About 1.6 kilometres further south, 7-Eleven Charlemont is at 234.9. Keep going and 7-Eleven Armstrong Creek is also 234.9, with Ampol Foodary a few hundred metres away at 239.9. That is 11.6 cents between two servos on the same road, roughly 6 kilometres apart.

Torquay Road is much the same. 7-Eleven Armstrong Creek Town Centre is about 2.2 kilometres from APCO Mount Duneed on that road, yet it charges 6.6 cents more.

7-Eleven's own sites make the point best. Waurn Ponds is at 228.3, while the Armstrong Creek Town Centre site, about 3.7 kilometres away, is at 234.9. As recently as 26th Sep, Waurn Ponds was also on 234.9. Over the following three days it came down twice, first to 229.9 and then to 228.3, matching APCO exactly. The brand's three sites to the south and east are still at 234.9.

Local competition explains part of it. 7-Eleven Waurn Ponds has Shell, BP and EG Ampol all within a kilometre, and APCO and BP about 2.7 kilometres away in Grovedale. The Barwon Heads Road sites in Charlemont and Armstrong Creek have no independent alongside them. Competition does not explain the Town Centre site, though. It holds 234.9 with APCO Mount Duneed 2.2 kilometres down Torquay Road. So how much of the gap is competition, and how much reflects newer suburbs with fewer choices? Whatever the answer, the price under a brand's sign can depend on where the servo sits.

A fortnight of increases

All of this sits on top of a substantial climb, which you can follow on our price trends page. BP Grovedale listed unleaded at 212.3 on 15th Sep and is now at 228.3, up 16.0 cents in a fortnight. Metro Petroleum Corio has risen 12.0 cents over the same period.

The cheapest unleaded in the sample is still in the north. Metro Petroleum Corio is at 221.9, and United Corio North and Gel Motors in North Geelong are both at 225.9. At the other end, Ampol Foodary Armstrong Creek is 18.0 cents dearer than Metro Corio.

E10 and diesel

E10 prices follow the same lines. APCO lists E10 at 226.3 at its Grovedale, Mount Duneed, Newcomb and North Geelong sites, and Liberty Belmont matches it. The three 7-Eleven sites in Armstrong Creek and Charlemont are at 232.9, the same 6.6 cent gap. Metro Corio is lowest at 219.9.

On diesel, Metro Corio is well clear at 267.2, about 8 cents below the next cheapest regular diesel, 275.3 at both Liberty and Belmont Petroleum.

What this means at the bowser

On a 50 litre tank, the 6.6 cent gap between Armstrong Creek and Mount Duneed is worth $3.30. Filling up in Corio instead of at the dearest Armstrong Creek servo saves $9.00. Motorists in the southern estates whose drive already takes them past APCO Mount Duneed or the Grovedale strip can have that saving without going out of their way. The savings calculator shows what a gap like this adds up to over a year.

Servos in Victoria can change their prices at any time, so these gaps can open or close overnight. Checking current unleaded petrol prices before heading out is the simplest way to see which side of the line a servo sits on.

I will be watching whether 7-Eleven brings its southern sites down to 228.3, as it did at Waurn Ponds. Armed with this information, motorists in the southern estates can avoid paying 6.6 cents a litre more than drivers a few kilometres away.
