One of the most common approaches to public housing crime prevention is situational crime prevention, which focuses on the physical environment. While research has indicated the need for a multifaceted approach to public housing crime prevention, the bureaucratic response has typically been anchored in design and situational or physical remedies. Further, security in public housing may involve the provision of responsive management services and the participation of tenants in the control of their environment. In Melbourne, crime prevention initiatives have focused on security in 21 high-rise public housing estates. Attention has been paid to tenant-driven demands for greater security, management responsibilities for providing security, the role of technology in providing security, and tenant-management cooperation. Implications of tenant decision-making in the provision of public housing security are discussed. 44 references
