TL;DR: The belief that “they all put the price up on the same day, like they’ve been on the phone to each other” is — for the up-move — true. On Monday 7 September, 325 of 500 Brisbane-metro stations (65%) changed their reported price in that single day, and 69% of those landed in the peak band at 205.9 c/L or above. Another 119 moved on Tuesday, so 89% of the metro re-priced inside 48 hours. The five days before were dead quiet: 3, 9, 7, 8 and 16 stations. The metro median jumped 205.9 to 207.9 that Monday. I usually come here to bust the folklore. Not this week. The driver who says “they all did it at once” is right.
Most weeks I take a driver’s belief, hold it against the Queensland Government price feed, and it doesn’t survive contact. That’s the job. So I want to be clear up front that this one is the exception: I went in expecting the “they all hike together” story to fall apart into a gradual, staggered drift — the way most of these do — and the feed refused to let me. It held. Here’s the number.
The claim
It’s the oldest servo complaint there is, and it always comes with the same edge of suspicion:
“They all put the price up on the same day, overnight, like they’ve been on the phone to each other.”
Two things are being claimed at once there. One is timing: they move together, in a burst, not one-by-one over a fortnight. The other is why: someone’s coordinating it. I can test the first from the feed directly. The second I’ll be careful with, because it’s an accusation and the feed doesn’t prove it. Take them in order.
What we checked
Everything below is the Queensland Government price feed — the price each station reported charging, not a driver’s guess at the bowser. There are no user submissions in any of it.
The feed records, for each station, the date it last changed its reported price. So for every one of the 500 Brisbane-metro ULP stations in range, I read off which day it moved, and counted how many moved on each calendar day from 2 to 8 September. If the folklore is right, one day should tower over the rest. If it’s wrong, the changes should smear evenly across the week as stations drift up independently.
What the feed shows
They don’t smear. They cliff.
- 2 Sep: 3 stations changed price.
- 3 Sep: 9.
- 4 Sep: 7.
- 5 Sep: 8.
- 6 Sep: 16.
- 7 Sep (Monday): 325.
- 8 Sep (Tuesday): 119.
Read those first five days again. Three, nine, seven, eight, sixteen — a quiet, near-dead market, a handful of sites twitching a day. Then Monday, and two-thirds of the entire city moves at once. Not a drift. A step.
And it’s overwhelmingly an up-move, not a scatter of little corrections. Of Monday’s 325 movers, 224 — 69% — landed in the peak band at 205.9 c/L or above. The metro median jumped from 205.9 on Sunday to 207.9 on Monday in that one day. Sixty-five per cent of the city changing price, most of them to the top, on one Monday, with the median stepping up a full two cents: that is the folklore, drawn to scale.
Why it happens — and why it isn’t a phone call
Here’s where I have to be fair, because the timing being true does not make the accusation true. “Like they’ve been on the phone to each other” implies coordination — servos ringing round to agree a price. The feed shows synchronised timing. It does not show a phone call, and I’m not going to pretend it does.
There’s a plainer explanation that needs no conspiracy, and it’s the one the mechanics actually support. This is price-cycle behaviour. The majors lead a restoration — they take the price back to the top of the cycle — and the pack follows within a day for a reason that has nothing to do with collusion and everything to do with not wanting to lose money: nobody wants to be the one cheap servo still holding the old price while every station around them is 8 cents higher. Being the last to hike doesn’t win you loyal customers; it just means you sold your tank of fuel too cheap. So once the restoration starts, following fast is the rational move, and the public price feed makes following instant — every operator can see, in real time, that the market has moved and match it within hours.
That’s signalling, not collusion. The same public feed that lets you find the cheap servo lets them watch each other. It’s the up-half of the pattern Dan measured in prices up fast, down slow: the restoration is fast and collective, because following the leader up is a one-day decision, while the fall afterwards is slow and staggered, because being first to cut is the move nobody wants to make. Same feed, opposite shape. If you want the full machinery of how a Brisbane lap runs — trough, restore, grind down — that’s the cycle explained. This week you’re watching the sharpest edge of it: the restore.
The verdict
TRUE. The up-hike is genuinely synchronised. Two-thirds of Brisbane changed price on a single Monday, most of them straight to the peak band, after five dead-quiet days — and 89% of the metro had re-priced inside 48 hours. The driver who says “they all did it at once” is not imagining it and is not exaggerating. For the up-move, they really do move together. What they don’t need is a phone call: the cycle and the public feed do the coordinating in plain sight.
So what for you
The practical read is the timing edge, and it cuts one way this week: the restoration has already happened, so this is the wrong week to be casual about where you fill. When you see the market cliff up like this — a quiet stretch, then a Monday where everything jumps to the top band — the cheap window has closed and it won’t gently reopen. The fall back down is the slow, staggered half, so patience from here is worth real cents, but only if you’re watching. The one servo that hasn’t followed yet is exactly the one worth finding, and on a synchronised-hike day there are still stragglers on the old price for a few hours. Pinly Fuel shows you every servo’s price around you off the QLD Government feed, so on a day the whole city steps up, you can spot the ones that haven’t — before you pull in, not after.
How we measure: this is the QLD Government feed’s per-station “date last changed” field for 500 Brisbane-metro ULP stations, counted by calendar day, 2–8 Sep 2026. The honest limit is that the feed gives the date a price changed, not the exact hour — so I can show the up-move was synchronised to a single day, but not literally “overnight at 2am.” Some of Monday’s 325 movers may be small or non-hike changes rather than full restorations; I can’t split those cleanly. But 69% landed in the peak band at 205.9+ and the metro median rose 205.9 to 207.9 that day, so the direction isn’t in doubt: this was a collective up-move. This is ULP/91, Brisbane metro only, one cycle in one city — a diesel or a longer multi-cycle run could soften or sharpen the picture, and “synchronised timing” is not, on its own, evidence of anyone coordinating.
