The energy policy of Australia is subject to the regulatory and fiscal influence of all three levels of government in Australia, although only the State and Federal levels determine policy for primary industries such as coal.

Australia is the 10th most coal-dependent country in the world. Coal and natural gas, along with oil-based products, are currently the primary sources of Australian energy usage and the coal industry produces over 30% of Australia's total greenhouse gas emissions. In 2018 Australia was the 8th highest emitter of greenhouse gases per capita in the world.
