When Is the Cheapest Time to Buy Petrol?

Fuel prices follow predictable cycles in major Australian cities. Understanding these cycles can save you hundreds of dollars per year. The price cycle pattern is particularly pronounced in Sydney, Melbourne, Brisbane, Adelaide, and Perth.

In a typical cycle, prices rise sharply over one to two days, often by 20 to 40 cents per litre. Prices then gradually decline over one to two weeks. The cycle repeats roughly every three weeks. Savvy drivers fill up during the declining phase, typically at the weekend or early in the week.

To find the bottom of the current cycle, use fuel price tracking apps and websites that show historical price trends for your suburb. Plan major trips to coincide with low-price periods when possible. Alternatively, consider joining a petrol discount club or using a fuel rewards credit card.

Regional areas outside major cities generally do not follow the price cycle pattern. Prices there tend to be more stable but slightly higher due to transport costs. Electric vehicles offer an excellent long-term alternative to paying petrol prices altogether.
