The National Disability Insurance Scheme is a government scheme for the provision of support and care to people with disability who meet the relevant criteria. The scheme was enacted in Australia by a piece of Commonwealth legislation called the National Disability Insurance Scheme Act 2013, referred to as the Act. Much of the detail of how the Scheme works is provided in corresponding Rules, which are a form of subordinate legislation, and in the Operational Guidelines based on the Rules.
During 2013, the scheme was branded and promoted as DisabilityCare Australia.
The Scheme is administered by a dedicated government agency: the National Disability Insurance Agency. This body is referred to as the Agency or the NDIA.
