Vulnerability to crime is a common problem on large public housing estates, and therefore a key issue in the public housing estate regeneration programs that have emerged in all states of Australian in the last decade (Randolph et al, 2005). Three broad categories of regeneration strategies can be identified: physical/spatial, social, and managements interventions, and various regeneration programs adopt different mixes of these (Randolph and Judd, 2000). The effectiveness of these strategies in reducing crime is therefore a critical question. This paper discusses the findings of an AHURI (Australian Housing and Urban Research Institute) funded research project investigating the relationships between community regeneration strategies and crime reduction in areas of public housing concentration (Judd et al 2002, Samuels et al 2004 and 2005).1 Nine study areas were selected across three states – three involving major physical/spatial interventions, three with predominantly social interventions and three ‘control’ areas without any formal regeneration program.
