For most of the 2010s Adelaide had the longest discount cycle in Australia, stretching to five weeks between troughs. Since 2022 it's compressed to roughly two to three weeks, more in line with Sydney and Brisbane. The peak-to-trough swing is still substantial — typically 25-35¢/L — but the timing window for cheap days is now shorter, so getting the call right matters more than it used to.
Adelaide's only refinery, Mobil's Port Stanvac, closed in 2003. Every litre of petrol sold in South Australia is now imported by ship, mostly from Singapore and South Korea. That makes Adelaide unusually sensitive to the Singapore MOGAS benchmark and AUD/USD movements — the macro signals PetrolPulse tracks tend to flow through to Adelaide pump prices a few days ahead of refining-state capitals like Brisbane and Melbourne.
South Australia's Fuel Pricing Information Scheme has required real-time mandatory price reporting since 2018, so PetrolPulse data for Adelaide is as fresh as Sydney's. The market is smaller though — roughly 600 stations statewide — and brand diversity is thinner. On Pasadena Road, Marion, and out through Noarlunga is where the discounters concentrate and where the cheapest prices typically appear first on any given cycle.
