I mustn't be very good at explaining this. I'll try again.
Collusion is only possible between a small number of suppliers. There are too many fuel stations to collude when all it would take is one to break ranks if this were to give a commercial advantage. Collusion is not necessary for the observed outcome.
The bottom of the cycle is highly competitive and is set to attract savvy buyers who shop around not just between suppliers, but between days of the week. They take note of how much they paid last time and they will not pay significantly more than this next time - they know how much they can buy fuel for if they are patient.
Many other buyers either don't know how cheap fuel can get, or don't care; their priority is convenience. By raising prices most of the time these buyers (and no doubt the proportion of buyers in this category varies geographically) usually pay well above the lowest price, and if they do pay the lowest price it is purely by chance. If they are motivated by convenience it is likely that the busy-ness of their local station at the low point of the cycle will put them off buying at that time.
So in essence, the variability of pricing is driven not by lack of competition, but the fact that suppliers maximise profits (as they should) taking advantage of the fact that many buyers do not even look at the price before they buy. Fuelwatch is a taxpayer-funded attempt by government to educate the public and reduce the profits of fuel retailers. There is nothing inherently uncompetitive about it.
Fuelwatch very handy in WA, as there are huge fluctuations by day and by supplier, as Aus1111 stated
Today's cheapest ULP, north of the river, $110.5, most expensive $1.32
Tomorrow $1.11 to $1.43
Don't know who is colluding who, but easy to get the better deal.
If I need fuel, do a quick check, take note of the cheapest stations out of the dozen I either drive past, or involve a minor detour.
Not massive savings overall but $250 to $500 per year?
Actually best not to go to the absolute cheapest as there is often a large queue.
