This is how it works in WA. Remember that "failed experiment" fuelwatch? Well, that was a WA innovation that never went away. It was here first, and is still very popular. You can load the map and immediately see that the cheapest fuel within a few km of the city is Shell Highgate. It's also super handy when you're in a part of town that you aren't familiar with/don't know where the local servos are.

You know these prices are set until midnight, so you can plan your day. From late afternoon, the site will show tomorrow's prices as well. So you can see whether the price is cheaper tomorrow or today. Maybe Highgate is out of your way? You can see the cheapest fuel that is on your way.

I have no idea why this system didn't take on nationally. It is so much better than going "ooh - cheap fuel, I'll fill up on the way home from the shops", only to see it went up 10c in the next hour. I'm out of touch with Melbourne's fuel prices these days, but a few years back Perth was consistently 20c/litre cheaper than Melbourne. Is that still the case?

They should force fuel prices to be locked for 7 days. Changing it on a daily basis is bullshit.

I’m sure that this will mean that instead of fuel prices being inflated on the Friday Morning before a long weekend, they will be inflated on the Thursday Morning before a long weekend.

This will mean that that those people who fill up on Payday will be paying the inflated price, even if they are organised and plan ahead.
