Within the Australian political geography literature, there has been a growing body of work that has aimed to understand the distinctive socio-economic and demographic patterns that characterise the Australian federal political landscape. Using results from the last two federal elections (2016 and 2019) this paper presents an analysis of polling booth catchments in the context of stability and change in voter support. Polling booths are assigned to four possible types-Stable Coalition, Stable Labor, Change to Coalition and Change to Labordepending on voter support. The Polling booths are then assigned a unique spatially de ned catchment which are then compared across a range of socioeconomic and demographic variables. The results suggest signi cant differences in the types of polling booth catchments across ve key indicates. These differences can be used to understand the distinct and changing nature of Australia's political geography and add an important component to the existing literature.
