How Adelaide pricing works
South Australia’s scheme, administered by Consumer and Business Services, requires real-time price reporting from stations. Like Queensland, SA publishes the data rather than building a consumer app.
FuelNow reads the scheme directly – official reports only, no crowd-sourcing.
Timing your fill-up in Adelaide
Adelaide runs a petrol price cycle with sharp jumps and slow falls, and it has been irregular lately. Whatever the cycle is doing, the map shows the cheapest station in view at a glance. The ACCC publishes current cycle guidance for Adelaide.
