The State of Australian Cities (SOAC) national conferences have been held biennially since 2003 to support interdisciplinary policy-related urban research. SOAC 2021 was hosted collaboratively and online by RMIT University, Monash University, Swinburne University and the University of Melbourne.

Refereed papers and extended abstracts at SOAC 2021 focus on urban and regional transitions in the COVID recovery era to report and appraise the social, spatial, and economic consequences for equity, inclusion and justice. The conference aims to connect these questions to urban practice and inform more robust policy and public discussions about the emerging new futures of Australasian cities and regions. In keeping with past SOAC conferences, SOAC 2021 papers are organised into broad thematic tracks: City Economics & Economies, City Governance, City Health & Liveability, City & Nature, City Movement & Infrastructure, City Structure, City Social & Housing and, for the first time this conference, a track called 'Reckoning with Settler Colonial Cities'.

Papers from all past SOAC conferences can be found at the State of Australian Cities Conferences Collection on APO.
