Your Child Just Got an Autism Diagnosis in Sydney: What Happens Next

Getting an autism diagnosis for your child brings up a complicated mix of emotions. Relief that there's finally an explanation. Grief for the path you thought you were on. Uncertainty about what comes next. And often, an overwhelming amount of information arriving all at once from the diagnosing team.

This post is a practical guide for the weeks and months after diagnosis — what to prioritise, what's actually useful, and where to find support in Sydney.

Give Yourself Time to Process

Before you do anything else: give yourself permission to have a reaction.

Many parents throw themselves into research and appointments immediately after diagnosis, which is completely understandable. But it's also worth acknowledging that this is a significant moment. The diagnosis doesn't change who your child is — but it does change how you understand them, and how you'll need to advocate for them. That takes time to integrate.

Understanding the Diagnosis Report

The assessment team should provide a written report outlining your child's profile across various domains — social communication, sensory processing, cognitive abilities, and adaptive functioning. This report is important: it will be used by schools, the NDIS, and other services.

Read it carefully and ask questions if anything is unclear. You are entitled to a follow-up conversation with the assessing team to go through the findings.

NDIS — Should You Apply?

If your child is under 7, they may be eligible for the NDIS Early Childhood Approach, which provides early intervention support without a formal NDIS plan. If they are 7 or older, you can apply for a standard NDIS plan.

Not every autistic child needs the NDIS — it depends on how significantly the autism affects their daily functioning. But if your child would benefit from regular occupational therapy, speech therapy, psychology, or other allied health support, the NDIS can fund this.

The application process can be daunting. You'll need supporting documentation from the diagnosing team and any other treating professionals. The diagnosis report will be a key part of your application.

If you're not sure whether to apply, it's generally worth doing — you can always choose not to use the plan once it's in place.

Telling the School

If your child's school doesn't already know about the diagnosis, you'll need to decide when and how to tell them.

In NSW, a formal autism diagnosis significantly strengthens your ability to request a Learning Support Plan and additional classroom adjustments. Schools are required under the Disability Standards for Education to make reasonable adjustments once they are informed of a disability.

Request a meeting with your child's teacher and the school's Learning and Support Teacher (LaST) as soon as you're ready. Bring a copy of the diagnosis report, and come prepared with specific requests — not just "more support" but concrete adjustments based on your child's profile.

Finding the Right Allied Health Support

Most autistic children benefit from at least some allied health support — occupational therapy for sensory processing and daily living skills, speech therapy for communication, and sometimes psychology for anxiety or emotional regulation.

Waiting lists in Sydney can be long — sometimes 3 to 6 months for a good OT or speech therapist. Start the search early, even while you're still processing the diagnosis.

Ask the diagnosing team for referrals. Other autism parents are also an excellent source of recommendations — local Facebook groups for parents of autistic children in Sydney often have up-to-date information on who is taking new clients.

You Don't Have to Figure This Out Alone

The post-diagnosis period is one of the hardest — you're learning an entirely new system while simultaneously parenting a child whose needs may be more complex than you realised.
