The NDIS was established to change how disability support was organised and funded in Australia. Its development followed years of concern about the availability and consistency of existing services.
The Productivity Commission's 2011 inquiry into disability care and support provided a major foundation for the scheme. The National Disability Insurance Scheme Act was passed in 2013, and the first trial sites began that year.
What was intended to change?
The scheme introduced individual planning and funding for eligible people, with an emphasis on participation, choice and control. The insurance approach also considered support needs over time rather than only the cost of a service in a single year.
These principles help explain why an assessment considers activities, circumstances and the assistance a person needs. A diagnosis alone does not describe every part of that situation.
The historical purpose is important context, but it is not the complete set of rules governing an individual decision today.
The NDIS is one part of the support system
Not every person with disability meets NDIS eligibility requirements. Health, education, aged care, employers and community services also have roles.
An NDIS plan is not general income support, and the scheme does not fund every expense associated with living with disability. Particular supports need to meet the applicable funding requirements.
This means an assessment may identify a genuine need while recognising that the response belongs with another service. That distinction should be explained rather than presented as proof that the need is unimportant.
Where individual evidence fits
For an access or funding decision, the NDIA needs information relevant to the requirements it is considering. Depending on the question, that may include treating evidence, the person's account, functional assessment and information about existing assistance.
An FCA is one possible source. It should not be presented as something every person must purchase to exercise their rights or be taken seriously.
Useful evidence explains the actual activity or support question and makes its limitations clear. Repeating the scheme's founding principles cannot, on its own, establish an individual eligibility criterion or justify a particular support amount.
Principles and decisions
A person may reasonably ask whether a decision reflects the applicable law and evidence. Disagreeing with a decision and experiencing changed circumstances can involve different review or plan-change processes.
A general history article cannot determine which process applies to an individual. The decision notice and current official guidance are the appropriate starting points, with independent advice where needed.
A scheme that is changing
Policy position checked on 22 September 2026: the Australian Government describes a staged transition of adults to new framework planning from April 2027 to the end of 2030. This is not the process already applying to every participant.
Thriving Kids has a separate phased rollout beginning in October 2026, with related NDIS access changes described for January 2028. A rollout start does not mean every service is immediately available locally or that an existing child's plan automatically ends.
Other 2026 reforms have their own start dates. Check the official guidance for the particular decision rather than relying on a historical description or assuming every announced change has already begun.
