Trends and Spatial Patterns of Infill Development in Melbourne Metropolitan Local Government Areas

Urban consolidation has been featured in Australia for over twenty years as a growth management tool to accommodate an increasing population while reducing urban sprawl and preserving open space on the fringes. Although infill development (also known as dual occupancy) has long been possible, and over the present decade, encouraged under new urban consolidation policy, monitoring of the inevitable changes in residential urban form has not occurred. Thus decision support teams in strategic planning cannot offer detailed advice on the implications of the changed patterns of either changed population densities or changes to access to existing infrastructure and services. We report here the results of applying a data integration framework and tool for systematically detecting infill pattern changes, land parcel by land parcel, first devised and applied to data from the City of Monash. The synthesis presented here refers to infill mapping in different local government areas in the Middle and Outer regions of the Melbourne Metropolitan Area (MMA), including Monash, Knox, Casey, and Whittlesea local government areas. Thus the utility of infill mapping for urban development monitoring and urban planning can be discussed in reference to the MMA as a whole.
