Local government is the third-level of government in Australia, administered with limited autonomy under the states and territories, and in turn beneath the federal government. Local government is not mentioned in the Constitution of Australia, and two referendums in 1974 and 1988 to alter the Constitution relating to local government were unsuccessful. Every state/territory government recognises local government in its own respective constitution. Unlike the two-tier local government system in Canada or the United States, there is only one tier of local government in each Australian state/territory, with no distinction between counties and cities.

The Outback Communities Authority (OCA) is a statutory authority in South Australia (SA) created under the Outback Communities Act 2009. It has been established to "manage the provision of public services and facilities to outback communities" which are widely dispersed across the Pastoral Unincorporated Area which covers almost 60% of South Australia's land area. The authority has its seat at both Port Augusta which is located outside the unincorporated area and at Andamooka. The authority serves an area of 624,339 square kilometres, slightly smaller than France. The area has a population of 3,750, of whom 639 are Indigenous Australians, and includes several large pastoral leases and mining operations.
