Why Are Petrol Prices High in Perth?

What affects your petrol price

Follow the price from international fuel costs to the local bowser, then check current station reports before filling.

High petrol prices rarely have one cause. International fuel costs and exchange rates shape the wholesale starting point; tax treatment, freight, station costs, retail cycles and local competition shape the final price.

International fuel prices and the dollar

Petrol prices in Australia are influenced by international refined-fuel benchmarks and exchange rates. Retail prices do not move by a fixed amount or after a fixed delay, so compare dated wholesale and retail figures.

Published wholesale benchmark

The terminal-gate price (TGP) is a published wholesale benchmark for fuel collected at the terminal, currently around 225.2 c/L. Australian AIP figures include fuel excise and GST. Transport from the terminal and retail operating costs come later.

Retail petrol cycles

Regular unleaded prices in several capital cities can rise sharply during a reset and then ease. Cycle length changes by city and over time, so use the current chart instead of relying on a fixed weekday.

Fuel taxes

Fuel excise and GST are already included in the Australian terminal-gate benchmark. Adding them again would double-count tax. Current rates can change, so this page does not use a fixed cents-per-litre tax figure.

Transport, station costs and local competition

Freight from the terminal, station operating costs, brand pricing and nearby competition can all affect the pump price. A national or city average can compare one area with another, but it is not the price at a particular bowser.

Sources

Freshness

Read the date on wholesale and market figures and the source report time on station prices. The series update on different schedules and should not be treated as simultaneous unless their dates align.

Limitations

A wholesale move does not reach every station by a fixed amount or after a fixed delay.
A city or national average can compare areas, but it is not a price available at every bowser.
Forecasts and cycle charts describe possible market direction, not the next price at one station.

Petrol prices in Perth: questions

Why are petrol prices high in Perth?

Over the last 90 days, Thursday was usually the dearest day and Wednesday the cheapest. That does not identify the current cycle position. The underlying drivers are the same everywhere. Crude oil and the Australian dollar, wholesale costs, fuel taxes and how much competition is nearby.

What is a good petrol price in Perth today?

The lowest listed petrol price in Perth is around 213.9c/L, against a city average of 229.7c/L. Check stations near the lower end of that range first, and review each update time before driving.

When will petrol prices drop in Perth?

Over the last 90 days, Wednesday was usually the cheapest day, but that does not predict the next price move. Use the current cycle chart and today’s station prices. If the direction is unclear, compare nearby stations rather than relying on the calendar.

Why are prices different across Perth?

Stations a few kilometres apart in Perth can differ by 20-30c/L on the same day, driven by local competition and where each site sits in the cycle. Compare suburbs on the Perth city page before you fill up.
