 This study examined the characteristics and components of the legal framework that influences the walkability of built environments in Australian states and territories. It found that most states and territories have developed jurisdiction-wide statutory tools that contain relevant design considerations for walking. These tools influence walkability by setting objectives for planning zones and aspects of development, as well as establishing criteria to achieve those goals. However, the variability in jurisdictional approaches presents challenges and raises uncertainty about the scope and strength of legal support for creating walkable environments at the national level. Further policy surveillance and epidemiological analysis are needed to refine the specifications of laws that influence walking in Australia.
