Although all human beings experience vulnerability, people with disabilities experience heightened vulnerability. For some people, the consequences of this heightened vulnerability may include social devaluation, physical and social rejection, a loss of control over important areas of their lives and brutalisation. Advocacy is one vital response to vulnerability and its consequences. This monograph presents the results of the National Advocacy Research Project. It explicates the need for and the purposes of advocacy for people with disabilities and provides an account of the fundamental principles which underpin effective advocacy. It analyses the key issues which are facing Australian advocacy efforts and finally presents a list of recommendations which relate to the future development of advocacy within Australia.
