Foster's Lager is an internationally distributed brand of Australian lager. It is owned by the Japanese brewing group Asahi Group Holdings, and is brewed under licence in a number of countries, including its biggest market, the UK, where the European rights to the brand are owned by Heineken International.

Beer arrived in Australia at the beginning of British colonisation. In 2004 Australia was ranked fourth internationally in per capita beer consumption, at around 110 litres per year; although, the nation ranked considerably lower in a World Health Organization report of alcohol consumption per capita of 12.2 litres. Lager is by far the most popular type of beer consumed in Australia.
