- Level 2 or 3 autism is on the NDIA's List A, which generally meets the disability requirements.
- Level 1 usually needs more evidence of how autism affects daily life.
- Younger children with lower needs will increasingly use Thriving Kids.
- Strong evidence from clinicians makes a big difference.
How does NDIS eligibility work for autism?
The NDIS funds reasonable and necessary supports for people with permanent and significant disability, or children who need early intervention.1 The NDIA uses lists to guide access decisions:
- List A conditions are likely to meet the disability requirements.
- List B conditions usually need more evidence about functional impact.2
Autism diagnosed by a qualified clinician at level 2 ("requiring substantial support") or level 3 ("requiring very substantial support") is on List A. Autism at level 1 isn't, so the NDIS generally wants evidence about how it affects daily life. See What are the levels of autism?
What evidence do I need?
The NDIS asks for disability evidence from treating professionals, such as a paediatrician, psychologist, occupational therapist or speech pathologist.3 Helpful evidence usually covers:
- The diagnosis, who made it, and the level
- How your child manages communication, social interaction, learning, self-care and self-management
- What supports have been tried and what helped
What's changing with Thriving Kids?
From 1 October 2026, children 8 and under with developmental delay or autism and low to moderate support needs can get support through Thriving Kids, without needing a diagnosis. Governments have agreed in principle to change NDIS access for children from 1 January 2028. Children with high support needs stay eligible for the NDIS.4 See What is Thriving Kids?
