The price of petrol in Australia is dependent on world market prices
Crude oil, petrol and diesel are bought and sold in their own markets. Each market is
regionally based and there are linkages and transactions between regional markets.
Prices in regional markets reflect the supply and demand balance in each market and the
physical characteristics and quality of each commodity. Prices in regional markets can be
volatile and can move in different directions from each other.
This is why focusing on relevant markets and longer term price trends is more important than
focusing on volatile daily or week-to-week price movements.
Australia's regional market for petroleum products is the Asia-Pacific market.
Key crude oil pricing benchmarks for the Asia-Pacific market including Australia are Tapis,
Dated Brent and Dubai – not West Texas Intermediate (the US market benchmark) widely
reported in the media.
The Singapore price of unleaded petrol (MOPS95 Petrol) is the key petrol pricing benchmark
for Australia.
'Refiner margins' are the differences between product prices and crude oil prices, both of
which are set by the market, not by oil companies (eg. Singapore petrol 'refiner margin' =
MOPS95 Petrol price minus the relevant crude oil price).
Australian wholesale prices (or TGPs) are closely linked to Singapore market
prices
To meet Australian demand, around 20% of petrol is imported – mostly from Singapore and
South Korea.
Australian wholesale prices for petrol and diesel (including spot Terminal Gate Prices or
TGPs) are closely linked to the Singapore prices of petrol and diesel – not to crude oil
prices.
The Singapore benchmark price of petrol plus shipping costs and Australian taxes represents
almost the entire wholesale price of petrol – typically around 95% of TGPs.
The remaining 5% of TGPs reflect insurance, a quality premium for Australian fuel standards,
local wharfage and terminal costs and a small wholesale marketing margin (where
competitively possible).
Generally, there is a short time lag of 1-2 weeks between changes in Singapore prices and
changes in Australian TGPs, and this lag operates when prices are both rising and falling.
Daily TGP data are published by all wholesale suppliers (AIP website has average TGPs –
www.aip.com.au).
Retail (pump) prices can be volatile in some markets, reflecting intense local market
competition
Once fuel leaves the terminal gate (where TGPs apply), retail or pump prices vary across
metropolitan and regional areas, reflecting local area factors and competition.
TGPs are typically around 95% of pump prices. Apart from TGP, pump prices in Australia also
reflect land transport costs, marketing and administration costs, and the costs of running
service stations like wages, rent and utilities. The ability to cover these costs depends on
local area competition.
Retail prices in metropolitan areas also tend to follow a discounting cycle with prices
ranging from a peak to a heavily discounted trough.
Consumers clearly benefit by purchasing heavily discounted petrol at the low point in the
cycle – the ACCC and media provides advice on low price days. The ACCC has stated that the
cycle is a clear demonstration of vigorous competition and the discounting cycle clearly
benefits price conscious consumers.
The major oil companies directly own and operate only a limited number of service stations
across Australia (around 10%) and these are largely in metropolitan areas.
Country pump prices are generally higher and more stable than metropolitan prices due to
differing competitive and economic characteristics
Retail fuel prices are more stable in regional areas because there is a general absence of
discounting.
Costs also vary greatly between regional towns, reflecting differences in local competition,
freight and handling differences, as well as different operating margins depending on fuel
volumes and convenience store turnover.
Retail prices in regional areas are largely set by independent owner/operators (including
those who sell fuel supplied by one of the major brands under licence).
Australian consumers clearly benefit from our highly competitive fuel market where
retail petrol and diesel prices are among the lowest in the developed world
Vigorous competition means that profits made by fuel suppliers are typically a very small
proportion of the retail price (eg. average annual industry net profit over the last 12
years is around 2 cents per litre of all fuels sold).
