Over Australians—around 67 per cent of the total population—live in the nation’s capital cities. , with Melbourne’s population increasing by 2.3% in 2018-19, followed closely by Brisbane (2.1%) and Sydney (1.7%); across all capital cities the population grew by 1.8%.
A further Australians live in regional cities of more than 100,000 people. Some of these regional cities, such as the Gold Coast, are also experiencing significant population growth (with a between 2018 and 2019). were the only two cities with a population greater than 100,000 people in which the population declined in 2018-19.
As Australia becomes more urbanised, the development of effective, evidence-based ‘cities policy’ is firmly on the national agenda.
What constitutes a city?
Cities are commonly defined by measures of density, available amenities and population size. To define a major city the uses a threshold of 100,000 residents congregated around an urban centre, in which dwelling density exceeds 45/km2 and/or population density is above 200/km2. Internationally, , based on the clustering of urban centres, to demark the boundaries of cities to provide a consistent definition of cities and their commuting zones.
Who is responsible for cities policy?
In Australia’s tiered system of government, in which legislative authority is divided between federal, state/territory and local governments, so there are multiple layers of governance with different functions and these arrangements vary across Australia’s cities.
A review of federal government policies targeting cities since the 1990s, when a period of economic expansion began, shows a number of significant initiatives. However, in general, cities policies at the federal level have not been sustained. Recently, renewed interest in cities and urban policy at the federal level has delivered new policies, such as the launch of ‘City Deals’.
The role of states and territories
State and territory governments have carried the main responsibility for urban governance throughout Australia’s history. State and territory governments are responsible for providing infrastructure and delivering health and education services, as well as the management of urban planning. Australia's tax system means that despite the central role of state and territory governments in metropolitan governance, the delivery of major projects often depends in part on federal financial support.
The role of local governments
Local governments have direct responsibility for implementing planning decisions and the direct delivery of services to citizens, however . Local government autonomy is limited by low revenue and reliance on state and federal government subsidies. Additionally, is subject to state government legislation and it is not formally recognised in Australia’s constitution . There are examples emerging of cooperation between local governments to achieve shared objectives, and new research by AHURI will explore how this works in practice.
The challenges of three tiers of government
The interactions between the different levels of government in states and territories can present challenges in the efficient delivery of infrastructure and services.
There appears to be an important role for the Australian Government in addressing nation-wide challenges of issues which position cities as . Policies which are ‘portfolio specific’ rather than ‘place specific’ can lead to a . This can contribute to an uneven distribution of resources and development that compromises the functioning and sustainability of cities.
The emergence of the infrastructure bodies
Infrastructure Australia was established as an independent statutory body in 2008 to address the need to plan, prioritise and assess the long-term allocation of resources intended to develop cities and regions. State level infrastructure bodies have since been established in New South Wales (2011), Victoria (2015), Queensland (2015), South Australia (2018), Western Australia (2019) and Tasmania (2019 – within the Department of State Growth).
