Turning 18 on the NDIS: What Changes
NDIS turning 18: what changes when a young person becomes an adult — decision-making, consent, money, housing, work and their plan, explained plainly.
When a young person on the NDIS turns 18, the biggest change is legal, not clinical: in Australia, 18 is the age of adulthood, so the National Disability Insurance Agency (NDIA — the agency that runs the Scheme) now treats the young person as the decision-maker for their own plan. Their supports do not automatically stop or shrink. What shifts is who signs, who consents, who the NDIA talks to, and…

Frequently asked questions
Does my NDIS funding get cut when I turn 18?
No — turning 18 does not automatically cut your funding or trigger a review on your birthday. Your plan continues on its normal cycle. What changes is that you become the decision-maker for your own plan. Funding can change at a future reassessment based on your needs, but not simply because you…
Can my parents still deal with the NDIA after I turn 18?
Only with your say-so, or through a formal arrangement. Once you're 18, the NDIA treats you as the decision-maker and needs your consent before discussing your plan with a parent or carer. You can give consent to share information, or set up a nominee if more formal help is genuinely needed. Sort…
What's the difference between a nominee and a guardian?
A nominee is an NDIS-specific role, appointed through the NDIA, to act for you in dealings with the Agency. Guardianship (lifestyle decisions) and administration (financial decisions) are broader legal arrangements made by a state or territory tribunal. Guardianship is a much bigger step and only…
Do I get the Disability Support Pension automatically at 18?
No. The DSP is a Centrelink (Services Australia) payment, separate from the NDIS, with its own eligibility and rules — it isn't granted just because you turned 18 or because you're an NDIS participant. Payment rates and rules change over time, so check your own situation directly with Services…
Will the NDIS reforms affect me as I turn 18?
They may, over time. The new planning framework and support-needs assessment roll out progressively from 2027, and children under 18 aren't part of it initially — so turning 18 is roughly when a young person moves toward the adult pathway. Critical daily-living and personal-care supports are not…
