Cities are the places where many of the problems to which Australian public policy responds are most evident and indeed concentrated: health inequalities, unemployment, housing affordability, congestion, crime and violence and environmental quality. In the sense that where we live has some impact on how we live, cities are important places because most Australians live in cities and have always done so (Davison, 1995). While it is not always easy to define cities with any degree of clarity and consistency over time and between countries, most definitions include some combination of population size and density as well as historical recognition and function (OECD, 2012). The Major Cities Unit (MCU) of the Australian Government’s Department of Infrastructure and Transport recognises 18 major cities, each with a population of over 100,000, including the all state and territory capital cities and an increasingly important set of non-capital cities such as the Gold Coast, Newcastle and Wollongong. These major cities now hold three quarters of the nation’s private housing stock and the majority of jobs (DITMCU, 2013).
