Australia is currently undergoing sweeping changes in transforming and digitizing its planning and development sectors. However, numerous challenges still exist in consolidating and making accessible essential data in the country to effect evidence-based development policy-making. This has been argued to have tangible consequences in formulating solutions to urban problems, such as housing delivery, and driving new urban innovations that are data-focused. In this chapter, we discuss a new urban data governance model in the context of the development of a novel single housing data and analytics platform, which has been formulated based on Australia’s current issues on data disparity, ownership, and interoperability. This platform, the Australian Housing Data Analytics Platform, seeks provide researchers with an integrated data repository and transparent analytical capabilities that hopes to drive collaboration, public participation, and data democratization across the country. In line with PlanTech principles developed through the Australian Planning Institute, this chapter describes how data in Australia can be made as a public good and integral commodity for policy-makers for the better planning for our cities.
