Autism Assessment Cost in Sydney: Fees & Medicare Rebates
Cost Summary: An autism assessment in Sydney costs $1,036 to $1,303 out-of-pocket after Medicare rebates. This covers the paediatrician consultations across three to four appointments: the initial assessment, one or two reviews, and the formal diagnosis and treatment plan. Allied health assessments are additional if required.
Fee Table
Each paediatric consultation is billed under a Medicare item number. After your appointment, we process the Medicare claim on your behalf, and the rebate is returned to your nominated bank account, typically within 1 to 3 business days. The difference between our fee and the Medicare rebate is your out-of-pocket cost.

$300.00 | $76.00 | $224.00 |
Autism Assessment Pathway
Autism assessments involve evaluation across multiple areas of development: communication, social interaction, behaviour, sensory processing, and daily functioning. This typically requires more consultations than an ADHD assessment, and may involve allied health professionals contributing to the diagnostic picture.
Step 1: GP Referral
A referral from your GP is required and is valid for 12 months. Include as much detail as possible: speech and language concerns, social interaction, repetitive behaviours, sensory sensitivities, and how your child functions across different settings. Any prior assessments, childcare or school reports, or allied health involvement should be provided to the GP so these can accompany the referral. This gives the paediatrician a more complete clinical foundation before the first appointment.
Cost: Standard GP Fee
Step 2: Initial Consultation (Item 132)
A comprehensive first assessment covering detailed developmental, medical, and family history, physical examination, and clinical observation. The paediatrician will typically provide standardised questionnaires for completion by parents and, where applicable, by schools or childcare. Depending on the complexity and age of the child, the paediatrician may also refer to allied health professionals (speech pathologist, psychologist, occupational therapist) to provide additional assessment input.
Our fee: $650.00
Medicare rebate: $265.60
You pay: $384.40
Step 3: Allied Health Assessments (If Referred)
If the paediatrician refers your child to allied health professionals, these are separate appointments that contribute to the diagnostic picture. Speech pathologists, psychologists, and occupational therapists each conduct their own structured assessments and report their findings back to the paediatrician.
Not every child requires this step. In straightforward presentations, particularly in older children with well-documented histories, the paediatrician may reach a diagnosis from their own clinical assessment alone. Allied health assessment fees in NSW typically range from $200 to $450 per session, with Medicare rebates of approximately $100 to $160 per session.
Varies by provider (separate from paediatrician fees)
Step 4: Review and Diagnostic Formulation (Item 133, 1 to 2 visits)
The paediatrician collates all available information: their own clinical observations, questionnaire results, school and childcare reports, and any allied health assessment reports. In some cases, the paediatrician can synthesise this information in a single review and move directly to the formal diagnosis. In others, two review appointments are needed to fully evaluate the clinical picture. The number of reviews depends on the complexity of the presentation and how much supporting information is available.
Our fee: $400.00 per visit (1 to 2 visits)
Medicare rebate: $133.00 per visit
You pay: $267.00 to $534.00
Step 5: Formal Diagnosis and Treatment Plan (Item 135)
If a complex Neurodevelopmental Disorder (NDD) such as Autism Spectrum Disorder is confirmed, the paediatrician bills item 135. This produces the formal written diagnosis and comprehensive treatment plan, which is sent to your GP and to any allied health providers involved in your child’s care. Item 135 can only be billed once in your child’s lifetime. This is also the item that unlocks access to up to 20 Medicare-funded allied health treatment sessions.
Our fee: $650.00
Medicare rebate: $265.60
You pay: $384.40

Total out-of-pocket (paediatrician consultations)
Allied health assessments are additional if required
After an Autism Diagnosis
A confirmed diagnosis opens access to a range of support, funding, and treatment pathways. What is available depends on the diagnosis.
Medicare-Funded Allied Health Treatment Sessions
Once item 135 has been billed and the Neurodevelopmental Disorder (NDD) diagnosis is confirmed, the paediatrician can refer your child to allied health professionals for ongoing treatment, with Medicare rebates applying to each session. These are treatment sessions, separate from any allied health assessments that may have been conducted during the diagnostic phase.
How the sessions are structured
The paediatrician writes a referral specifying which allied health professionals your child should see and how many sessions per provider. The sessions are delivered in two courses:
First course: up to 10 sessions. Your child attends the referred allied health professionals for treatment. After the first course is completed, the allied health provider sends a written report back to the paediatrician covering the treatment provided, your child’s progress, and recommendations for ongoing care.
Second course: up to 10 additional sessions. The paediatrician reviews the allied health report and your child’s progress. Based on this review, the paediatrician can issue a new referral for up to 10 more sessions, which can continue with the same providers or be directed to different ones depending on your child’s evolving needs.
The total lifetime cap is 20 sessions. These do not reset annually, so they are worth using strategically based on your child’s priorities at the time.
Who your child can be referred to
Social communication therapy, language development, augmentative and alternative communication.
Psychologist
Behavioural therapy, anxiety management, social skills training, parent coaching.
Sensory integration, daily living skills, school readiness, fine motor development, self-regulation.
Physiotherapist / Exercise Physiologist
Gross motor development, coordination, structured exercise programs for regulation and wellbeing.
Allied health providers set their own fees. Treatment sessions in NSW typically range from $180 to $400, with Medicare rebates of approximately $90 to $160 per session depending on the provider type and session length.
NDIS
The NDIS is often the most significant source of ongoing support for autistic children. Eligibility depends on the level of the diagnosis:
- ASD Level 2 or Level 3: Typically meet the NDIA access criteria and are generally approved for funding, subject to standard evidence requirements.
- ASD Level 1: May qualify, but requires supporting evidence of how the diagnosis impacts daily functioning across communication, social interaction, self-care, and learning.
- Children under 9: Can access the NDIS Early Childhood Approach, which may provide support before a formal diagnosis is finalised. Contact an NDIS Early Childhood Partner to discuss eligibility.
The NDIS reports that autistic participants receive an average of approximately $32,800 per year in funding. Children under 7 receive an average of approximately $16,700 per year. Funding covers therapies (occupational therapy, speech pathology, psychology), support workers, assistive technology, and community participation. Individual plans are tailored to your child’s goals and assessed needs.
Medicare allied health sessions and the NDIS are separate
The 20 lifetime allied health sessions funded through Medicare (via item 135) are independent of any NDIS funding your child receives. If your child qualifies for the NDIS, the NDIS covers ongoing therapy, often hundreds of hours per year. The 20 Medicare sessions are particularly valuable for children who do not qualify for the NDIS, or as a bridge while an NDIS application is being processed.
School Support
The paediatrician provides diagnostic reports and letters for school funding applications, classroom adjustments, and integration support.
Medication
Not all autistic children require medication. Where co-occurring conditions are present (anxiety, ADHD, sleep difficulties), the paediatrician may recommend medication as part of the broader management plan, managed through ongoing follow-up consultations.
Ongoing Annual Costs
After the initial assessment phase, ongoing paediatric management follows a predictable annual pattern. The following reflects what most families should expect each year.
| Service | Frequency | You Pay (Annual) |
|---|---|---|
| Complex annual review (item 132) | 1 per year | $384.40 |
| Complex reviews (item 133) | 2 per year | $534.00 |
| Standard follow-ups (item 116) | 1 to 2 per year | $224.00 to $448.00 |
| ADHD medication (PBS-subsidised) | Monthly scripts | $92.40 to $300.00 |
| ADHD Management Annual Total | 4 to 5 visits + medication | $1,234.80 to $1,666.40 |
ADHD medication costs are included in the ADHD annual total above. PBS co-payment rates and medication details are covered here. You can track your PBS spending through the Medicare app.
NDIS funding can substantially reduce annual costs
If your child qualifies for the NDIS following an autism diagnosis, therapy costs (occupational therapy, speech pathology, psychology) are typically covered under the NDIS plan. In that scenario, the paediatrician visits listed above may be your only significant out-of-pocket health expense for your child’s neurodevelopmental care.
Medicare Safety Nets
Medicare tracks your family’s total out-of-pocket medical costs across the calendar year. Once those costs reach a certain threshold, Medicare increases your rebates for the remainder of that year. This applies to all out-of-hospital Medicare services, not just paediatric visits.
There are two thresholds. Once you cross the first, your rebate increases by a small amount. Once you cross the second, Medicare covers a much larger share of your costs.
Original Medicare Safety Net
2026 threshold: $594.40 in total gap costs per family per calendar year
Once crossed, your Medicare rebate on all out-of-hospital services increases slightly for the rest of the year. The increase is modest per visit. If you are going through an ADHD or autism assessment, your family will likely cross this threshold within the first 2 to 3 paediatrician appointments.
Extended Medicare Safety Net (EMSN)
This is where the larger savings apply. Once your family’s total out-of-pocket costs pass the EMSN threshold, Medicare covers an additional 80% of your gap on future services for the rest of the calendar year.
2026 EMSN thresholds:
- $861.20 for families holding a Commonwealth concession card or receiving Family Tax Benefit Part A
- $2,699.10 for all other families
The difference this makes to your out-of-pocket costs is significant:
Registering Your Family
For the safety net to work effectively, you need to register your family group so that everyone’s gap costs count toward the same threshold. Without this, each family member is tracked separately and you may not reach the threshold.
Log into myGov, go to Medicare, and register your family under the Safety Net section. Add your partner and dependent children. Alternatively, call Services Australia on 132 011. Once registered, all gap costs across your family are tracked automatically.
Tracking Your Progress
Open the Medicare app or log into myGov to check how close your family is to the threshold at any point during the year. If you are approaching the threshold, it may be worth scheduling upcoming appointments within the same calendar year rather than deferring to January, so the safety net benefit applies to those visits.
Private Health Insurance
Some private health funds offer rebates on specialist consultations and allied health under their extras cover. It is worth checking your policy, particularly for allied health visits such as speech pathology or occupational therapy. You cannot claim both Medicare and private health insurance for the same service, but extras cover may assist with costs that Medicare does not cover.
