The literature lacks a methodological framework to guide the selection of location and design characteristics of a 20-minute neighbourhood. The present study intends to fill this gap by developing neighbourhood typologies and performing a scenario-based approach to identify the types of 20-minute neighbourhoods that can increase walking propensity.

This research aims to explore the dual consideration of amenity and accessibility to facilitate effective place-based planning. By identifying Croydon South as a 'Low-amenity suburb' with high car dependency, a regression analysis revealed that bus stop density and commercial activity were variables that contributed to the increased percentage of walking.

To inform and ground the development of robust research and policy reflection on infrastructure governance in Australian cities, a systematic literature review was performed to understand the prevailing state of literature.
