This Sustainable Built Environment National Research Centre (SBEnrc) project, Mapping the Social and Affordable Housing Network1 aims to improve the productivity, effectiveness and efficiency of this network in Australia. This series of Western Australia network maps have been developed to facilitate a strategic yet pragmatic understanding of the complexities and associations in this network, and to better leverage outcomes for those in need of social and/or more affordable housing. These high-level maps (focusing on public, community and non-market rental housing) aim to identify, understand and describe the various elements of this complex system. The maps are a snapshot in time, finalised July 2019, following desk top analysis by the research team, and three workshops with industry stakeholders in Brisbane and Perth. The intent has been to identify all participants for the three tiers of government and for peak bodies/industry associations, whilst providing examples only for the remaining groups of participants involved in the network.
