Abstract: This paper presents the findings of a community-based participatory action research study that investigates Aboriginal people‘s experience of health and family services in the Northern Territory, Australia. The research is part of a larger program of work that addresses the multi-level change management required for implementation of the Northern Territory Government‘s Aboriginal Cultural Security Policy. Using empirical evidence generated from Aboriginal people—ranging across urban services through to remote locations—on the cultural security and cultural competence of current health service delivery in the Northern Territory, this article proposes a range of options for systemic, structural and individual level policy implementation and development of services.
