This is the third of four reports on the fieldwork for the evaluation of the Housing and Accommodation Support Initiative Stage One (HASI). HASI is a partnership between NSW Health, NSW Department of Housing (DoH) and non-government organisations (NGOs). The program’s objectives are to assist people with mental health problems to acquire and maintain stable housing, to improve community participation and quality of life and to provide a system of supportive stakeholders to work with people with mental illness towards recovery or maintenance (NSW Health and NSW Department of Housing 2005). This report presents the findings from the final phase of fieldwork (conducted in February and March 2006) and the longitudinal outcomes from Phases 1, 2 and 3. The latter findings are based on over 600 interviews with HASI stakeholders, including 219 client interviews. This report complements the first two evaluation reports (Morris et al 2005, Muir et al 2005). These three reports form the background for the final evaluation report in 2006.
