Local government in Australia is the third level of government division in Australia, and is administered by the states and territories, which in turn are beneath the federal level. Local government is not mentioned in the Constitution of Australia and two referenda in the 1970s and 1980s to alter the Constitution relating to local government were unsuccessful. Every state government recognises local government in its respective constitution. Unlike Canada or the United States, there is only one level of local government in each state, with no distinction such as cities and counties.

The states and territories of Australia are the second level of government division in Australia, between the federal government and local governments. States and territories are self-administered regions with a local legislature, police force and certain civil authorities, and are represented in the Parliament of Australia. Territories though, unlike states, rely on federal legislation and additional financial contributions to operate, and have less representation in the Senate.

Cadastral divisions in Victoria are called counties, which are further subdivided into parishes and townships, for cadastral or land administration purposes. Cadastral divisions of county, parish and township form the basis for formal identification of the location of any piece of land in the state. There are 37 counties and 2004 parishes and 909 townships. Parishes were subdivided into sections of various sizes for sale as farming allotments, or designated as a town and then divided into sections and these subdivided into crown allotments. However, many parishes do not follow county borders, some being located in more than one county.

The lands administrative divisions of South Australia are the cadastral units of counties and hundreds in South Australia. They are located only in the south-eastern part of the state, and do not cover the whole state. 49 counties have been proclaimed across the southern and southeastern areas of the state historically considered to be arable and thus in need of a cadastre. Within that area, a total of 540 hundreds have been proclaimed, although five were annulled in 1870, and, in some cases, the names reused elsewhere.

This is a list of local government areas (LGAs) in New South Wales, sorted by region. As of December 2020 there were 128 local government areas in New South Wales, listed below in alphabetical order by region. There is also the Unincorporated Far West Region which is not part of any local government area, in the sparsely inhabited Far West, and Lord Howe Island, which is also unincorporated but self-governed by the Lord Howe Island Board.

The local government areas (LGA) of New South Wales are the third tier of government in the Australian state. under the Local Government Act 1993 (NSW) they can manage their own affairs to the extent permitted by the legislation. They may be designated as cities or otherwise as areas, though the latter units may choose to use titles that had distinctions under older forms of the act. The smallest local government by area in the state is the Municipality of Hunter's Hill 5.7 km2 (2.2 sq mi) and the largest by area is Central Darling Shire Council 53,492 km2 (20,653 sq mi).

Local government in the Australian state of Victoria consists of 79 local government areas (LGAs). Also referred to as municipalities, Victorian LGAs are classified as cities (34), shires (38), rural cities (6) and boroughs (1). In general, an urban or suburban LGA is called a city and is governed by a City Council, while a rural LGA covering a larger rural area is usually called a shire and is governed by a Shire Council. Local councils have the same administrative functions and similar political structures, regardless of their classification. They will typically have an elected council and usually a mayor or shire president responsible for chairing meetings of the council. The City of Melbourne has a Lord Mayor and Deputy Lord Mayor, who are directly elected, and in the other councils a mayor and deputy mayor are elected by fellow Councillors from among their own number. Since 2017, the mayor of the City of Greater Geelong has not been directly elected. In addition, there are also 10 unincorporated areas, consisting of small islands or ski resorts, which are administered either by the state government or management boards.
