How Are Australian Local Governments Responding to the Homelessness Crisis? Findings From a National Study

Australian Journal of Social Issues, EarlyView.
ABSTRACT Australian local governments are facing intensifying pressures to respond to worsening visible homelessness. This paper presents one of the first national studies on how local governments are responding to these pressures, and the first since the onset of the post‐pandemic housing crisis.
