Petrol price cycles

Petrol prices move up and down in regular patterns or cycles. The cheapest and most expensive days to buy petrol can change from cycle to cycle. Use price cycles to help you decide when to buy petrol.

Petrol price cycles in capital cities

Sydney Melbourne Brisbane Adelaide Perth

A petrol price cycle is a movement in retail price from a low point (or trough) to a high point (or peak) to a subsequent low point. In these cycles, prices steadily go down for a period followed by a sharp increase.

Price cycles are the result of deliberate pricing policies of petrol retailers, and are not directly related to changes in wholesale costs.

The duration of petrol price cycles in Sydney, Melbourne, Brisbane and Adelaide varies from cycle to cycle, and has increased in recent years. In 2017, price cycle durations in these capital cities ranged from a low of 11 days to a high of 61 days.

Disclaimer

Historical data can only give an indication of the cheapest and most expensive days to buy petrol in the future, so consumers should use this information as a general guide only.

The charts are updated daily from Monday to Friday at around midday, and show average daily prices for the last 45 days. Updates on Mondays include prices for the preceding Friday, Saturday and Sunday.

Buying tips are usually updated around midday on Monday, Wednesday and Friday.

The buying tips may not always seem apparent from the charts. This is because the charts show historical prices.

The charts show average daily regular unleaded petrol for all cities except Sydney, which shows E10 prices.
