Specialized mental health services for the homeless, by working in close collaboration with existing homeless services, can successfully engage and manage patients. The application of homeless practices may need to become more widespread in public mental health services as patterns of accommodation change within the Australian population.

A history of homelessness is common in patients with psychosis using inner urban mental health services and is associated with poorer engagement with psychiatric services.

A population of complex patients with chronic mental illness are not effectively contained within a 'good enough' community-based mental health system. Active debate is required regarding the community's willingness to tolerate the risks and challenges that arise from the current approach. A collaborative care model involving case-based and incentive funding in combination with community-integrated complex care units may improve the care of these patients.
