What is the definition of a city in Australia?
Australia is a federal parliamentary democracy and constitutional monarchy comprising six states and ten territories. The country is highly urbanised, with 67% of its population living in metropolitan areas. The definition of a city in Australia varies between the states.
In New South Wales, only local government areas can be declared as "cities" by the Government, under the Local Government Act 1993. While the current Act does not specify any criteria for city status, a previous version of the Act stipulated that to be a city, a Council area must:
- Have a population of at least 25,000 people.
- Be an independent centre of population, not a suburb of another council area or centre of population.
- Satisfy the criteria in paragraphs (a) or (b) and be a homogenous centre of importance as a focus of regional commercial, governmental, or cultural activity.
New South Wales, therefore, has two types of "cities": those acknowledged on the register of the Geographical Names Board of New South Wales, and local government areas proclaimed as cities but not acknowledged on the Geographical Names Register.
State capital cities in Australia may include multiple local government areas (LGAs) within their boundaries, and these LGAs may be considered cities in their own right. Examples of state capital cities include Sydney, Melbourne, Brisbane, Perth, Adelaide, Darwin, and Hobart. These cities offer diverse products, services, and employment opportunities, attracting people with their concentration of services and cultural, leisure, and sporting activities.
While state and territory governments have traditionally held the main responsibility for urban governance, the Australian Government has recently shown renewed interest in cities and urban policy, launching initiatives such as 'City Deals' to address nationwide challenges related to population growth, new technologies, industrial transition, and climate change.

What is the capital of Australia?
Australia is a country and a continent. It is the smallest continent and one of the largest countries on Earth. It lies between the Pacific and Indian Oceans in the Southern Hemisphere.
The capital of Australia is Canberra. It is located in the northern region of the Australian Capital Territory, in the southeast corner of Australia. Canberra is roughly 150 kilometres (93 miles) inland from the country's east coast and has an elevation of about 580 metres (1,900 feet). It is the largest inland city and the eighth-largest city in Australia, with a population of around 430,000 to 467,000 people.
Canberra was founded in 1913, twelve years after the former British colonies of Australia federated in 1901, deciding to form the Commonwealth of Australia. The site of Canberra was chosen to be the capital city in 1908, and the designs for the city were chosen in 1912. An international competition was held to select the designers, and the winners were American architects Walter Burley Griffin and Marion Mahony Griffin. Construction of the city began in 1913.
Canberra was chosen as a compromise between Sydney and Melbourne, which were the two largest cities and the strongest candidates for becoming the capital. It was decided that the capital would be built in the territory of New South Wales, between the two cities, so long as it was at least 160 kilometres away from Sydney.
