Adelaide Petrol Price Cycle

Adelaide's price cycle runs approximately 7-14 days. Prices tend to be lowest mid-week — typically Tuesday and Wednesday — before rising toward Thursday and Friday. Some industry analysts note that Adelaide's cycle may differ slightly from Sydney and Melbourne due to a higher proportion of independent retailers setting prices competitively.

Understanding Adelaide Fuel Prices — The Fuel Excise

The Commonwealth fuel excise of approximately 48.8 cents per litre applies uniformly across Adelaide and South Australia. Federal budget decisions on the excise rate flow directly into Adelaide pump prices, making federal fiscal policy a key driver of local fuel costs.
