The Australian Automobile Association, in partnership with FuelTrac pty ltd, provides a fuel price report, every month.
Using this report you can compare the price at the pump for unleaded, premium unleaded, diesel and LPG fuels across all capital cities in Australia, for the last 13 months.
There are a host of factors that make up the price of fuel at the bowser. In September 2019, the cost of the actual refined petrol product made up around 46.7 per cent of the average pump price.
Another 37.7 per cent of the price was made up of taxes. This includes the Federal Government’s fuel excise, which imposes a tax of 41.8 cents per litre in the form of fuel excise (which increases twice a year in line with inflation), and 10% GST.
In September 2019, wholesale and retail costs made up the remaining 15.6 per cent (Source: ACCC).
