Building on the earlier National Liveability Studies supported by The Prevention Centre, and on other related work funded by the NHMRC CRE-HLC and the CAUL Hub, this final project aimed to inform policy and practice by providing both data and research-validated tools that would improve understanding of the relationship between built environments, daily activities and travel choices. This project aimed to: develop a national platform of urban liveability indicators temporally, spatially, and demographically, in order to benchmark and monitor the health and wellbeing of cities; assess the potential for achieving the 30-minute city by different modes of transport; use these indicators in conjunction with other data in a simulation model for selected capital and regional cities in Australia; and assess the merits of specific interventions designed to create healthy, liveable communities, including a health impact assessment.
