The State of Australian Cities (SOAC) national conferences have been held biennially since 2003 to support interdisciplinary policy-related urban research. SOAC 2019 was subtitled "Cities in an Age of Disruption and Innovation" and was jointly hosted in Perth by the University of Western Australia and Curtin University.

In keeping with past SOAC conferences, SOAC 2019 papers were organised into broad thematic streams: City Economics, City Environment, City Governance, City Structure, City Movement and Infrastructure, City Social and Housing and City Health/Liveability. All published papers were produced through a process of integrated peer review.

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