The Australian Institute of Health and Welfare, the Australian Bureau of Statistics, and governments at all levels, accept the definition of homelessness as an inability to obtain safe, secure, or accessible housing. Lack of affordable housing is a significant cause of homelessness. Homelessness signifies the unequal distribution of resources and opportunities, and a growing gap between rich and poor in our society. It is a critical health and wellbeing issue, resulting in social isolation and exclusion from opportunities and participation in community life. The result can be that families and individuals resort to violence or even suicide, because of the extreme stress associated with being unable to locate suitable accommodation.
