Wholesale fuel prices Australia are based on international benchmarks, which ensures local refiners will not sell all the fuel overseas to obtain higher prices. It is important to note benchmark prices do not include freight, insurance, transport costs and wholesale and retail margins, which are also added to reach the final retail price.
The wholesale price for LPG/Autogas in Australia is based on a benchmark price set in Saudi Arabia. This price is set once a month, and is published in US dollars per tonne. This price is converted into Australian cents per litre to form a base for local wholesale prices.
LPG/Autogas is generally made up of two gases - propane and butane. In Western Australia, it can vary from 100% propane to a 50/50 mixture of both gases. The Saudi Aramco Contract Price is actually made up of two figures - one for propane, and one for butane. The current Saudi Aramco Contract Prices are below (or in Adobe PDF format).
