Adelaide closed the week to 4 October 2026 at 232.9 c/L for unleaded, 2nd of the eight capitals, with diesel at 287.8.
Against the national average of 237.3, that is −4.4 cents; on a 60-litre fill the difference comes to $2.64.
South Australia's Fuel Pricing Information Scheme obliges servos to report price changes, and the feed reaches drivers through approved apps; access for a site like this one needs registration as a data user, so Adelaide is covered here by the weekly AIP figures and the terminal gate.
Adelaide also runs a sharp restoration cycle, one of the five big-city cycles the ACCC follows; this page can show its weekly result but not each day of it.
Wholesale against the bowser in Adelaide
Adelaide's servos bought at a terminal gate that averaged 229.6 c/L across the survey week and sold at 232.9: 3.3 cents of gross margin on unleaded, 24.2 on diesel. Terminal change: +1.5 in a week, +32.3 in four.
Five years of AIP data bracket Adelaide's terminal between 141.1 (8 December 2021) and 249.8 (26 March 2026). At 231.0 it sits in the top third of that range. Bowsers in Adelaide usually catch up with the terminal inside a fortnight (how that lag is measured).
