The National Disability Insurance Scheme (known commonly as the NDIS) was introduced as a radical new way of funding disability services in Australia. It is a rare moment in politics and policy making that an idea as revolutionary, ambitious and expensive as the NDIS makes it into its implementation phase. Not surprising, then, that the NDIS has been described by many as the biggest social shift in Australia since Medicare. This book will be a key text for scholars and public policy professionals wishing to understand the NDIS, how it was designed, and lessons learned through its introduction and roll-out. The book addresses how the NDIS has intersected with particular cohorts and sectors, and some of the challenges that have arisen. It highlights the experiences of people with disability through a collection of personal stories from participants and families in the NDIS. The key insights from this large scale public policy experiment are relevant for anyone interested in social change in Australia, or internationally.
