The City of Perth is a local government area and body, within the Perth metropolitan area, which is the capital of Western Australia. The local government is commonly known as Perth City Council. The City covers the Perth city centre and surrounding suburbs. The City covers an area of 20.01 square kilometres (8 sq mi) and had an estimated population of 21,092 as at 30 June 2015. On 1 July 2016 the City expanded, absorbing 1,247 residents from the City of Subiaco.
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 and 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 (largely) only one tier of local government in each Australian state/territory, with no distinction between counties and cities.
Local government in Australia is generally run by an elected council, and the area it administers is referred to by the Australian Bureau of Statistics as a local government area or LGA, each of which encompasses multiple suburbs and/or localities (roughly equivalent to neighbourhoods), often of different postcodes. LGAs are variously styled using terms such as "city", "town", "district", "municipality", "borough", "region" or "shire". These usually have geographic or historical significance, and there is rarely any legal distinction between them. For instance, cities and municipalities tend to apply to councils in urban and metropolitan areas, whereas districts and shires are found primarily in rural and regional areas. A local government area is also commonly known as a "city council", "local council", or simply a "council". Council members are generally known as councillors, and the head of a council is called the mayor, chairman or shire president. Some of Australia’s largest cities, such as Sydney, Melbourne, Brisbane, Perth and Adelaide, use the historical title of lord mayor. Councillors are usually elected from single-member districts known as divisions or wards, whilst the mayor or president is directly elected by all the voters within that council area. However, the mayor is often entitled to style themselves as a councillor, and is considered an ex officio member of the council. As of August 2016, there were 547 local councils in Australia.
The City of Brisbane is a local government area (LGA) which comprises the inner portion of Greater Brisbane, the capital of Queensland, Australia. Its governing body is the Brisbane City Council.
The LGAs in the other mainland state capitals (Sydney, Melbourne, Perth and Adelaide) are generally responsible only for the central business districts and inner neighbourhoods of those cities. However, the City of Brisbane administers a significant portion of the Brisbane Greater Capital City Statistical Area (GCCSA), accounting for just under half its population. As such, it has a larger population than any other local government area in Australia. The City of Brisbane was the first Australian LGA to reach a population of more than one million. Its population is roughly equivalent to the populations of Tasmania, the Australian Capital Territory and the Northern Territory combined. In 2016–2017, the council administered a budget of over $3 billion, by far the largest budget compared to those of the City of Sydney and City of Melbourne LGAs.
