How these numbers are worked out. Every figure is the median price across every priced site in South Australia, and every range is the 10th to 90th percentile — not the cheapest and dearest pump, so a single mistyped price can't move what you read here. Prices come from the state government fuel feeds (FuelCheck NSW, FuelPricesQLD, FuelWatch WA, Fair Fuel VIC, SA) and only count if they were updated in the last 72 hours. A price is discarded if it sits more than 30c below its own state and fuel-type median, which is how a feed's occasional nonsense figure gets caught; prices above the median are kept, because remote roadhouses genuinely charge far more. 40 prices discarded this build.
