Autism Assessment is for adults who want to know whether Autism explains a long-standing pattern in how they experience and respond to the world.
You might have been wondering about Autism for years, or it may be something you have only started considering recently. You may already have other diagnoses or explanations that account for part of what is happening, but still leave important parts of the picture unexplained.
You do not need to arrive knowing whether you are Autistic. The assessment aims to answer that question. A screening assessment is also available.

Autism is assessed from a pattern across your life. No single behaviour, characteristic or questionnaire result determines the outcome.

ADHD, trauma, mental health challenges, learning or cognitive differences, sleep, pain, medication and physical health can all shape your experiences. We consider how these interact rather than reading any feature in isolation.
Our assessment is comprehensive, so we always ask about experiences that sit outside the formal criteria: camouflaging (masking), monotropic attention, demand avoidance, difficulty identifying emotions or body signals, limited mental imagery and burnout. These are not Autism criteria, but they help explain your individual profile.
Together, this information helps the psychologist decide whether the overall pattern is consistent with Autism and what else may be contributing.
Autism Assessment draws on several sources of information because the clinical question concerns a developmental pattern, not a single point in time.
Before the main appointment, you complete questionnaires about current and past experiences. The results are read alongside the interview and developmental history, and do not determine the outcome on their own.

An Autism assessment should still explain the clinical picture when the information does not support Autism.
Many of the experiences that lead people to consider Autism are not specific to Autism. Sensory overload, social fatigue, a strong preference for predictability, intense or highly focused interests, difficulty identifying what you feel, and executive functioning difficulties all occur in other clinical contexts. What they mean depends on when they began, how consistently they have been present across your development and settings, and how they fit the rest of your profile.
If your developmental pattern does not fit Autism, we look at what else may account for your experiences. Depending on your history, that can include ADHD, trauma, anxiety or other mental health difficulties, learning or cognitive differences, sleep, pain, medication effects and physical health. Several may be relevant at once, and we consider how they relate to one another.
Autism Assessment cannot rule out every possible alternative. Where the information supports another clinical formulation, we explain that in the report. Where a different question needs its own assessment, we say what remains uncertain and what type of assessment would answer it.
The report sets out the outcome, the reasoning behind it, what appears to be contributing to your experiences, and any questions left unresolved. The purpose is to explain the pattern clearly even when Autism is not the explanation.
Additional letters can be prepared where a person needs documentation for a particular purpose, such as workplace accommodations.
These are prepared separately from the assessment report and attract an additional fee. Where the requested letter draws on information already established during the assessment, the report provides the clinical basis for that documentation.
Yes. Neuropsychological assessment answers a different question. It looks at attention, memory, processing speed and executive functioning, and is useful when an everyday difficulty could have more than one explanation. For example, trouble remembering things may come from inconsistent attention when you first learned them, from retrieval, from fatigue, sleep or pain. Testing helps tell those apart. Reading, writing and numeracy can be examined the same way.
Because some history and clinical information have already been gathered during your Autism assessment, it can be added at a $500 discount from the usual adult fee. Tier 1 is $2,180, Tier 2 is $2,680 and Tier 3 is $3,180.
Giftedness and twice exceptionality are examined using a Tier 1 assessment, which is $2,180 when added to Autism Assessment.
Your Autism assessment report is strengths-based, and it is good evidence for an NDIS application. It is not written to the NDIS criteria, though, so we offer a separate NDIS report as an add-on. That keeps the main report strengths-based while the NDIS report does the different job the NDIA needs it to do.
The NDIS report sets out how the interaction between your Autistic traits and your environment produces disability across the NDIS domains, and what supports would be appropriate. Our clinicians write these reports regularly and have experience advocating within the NDIS system.
You do not need to decide before you start. If you are considering the NDIS, book the assessment, and we can advise during it whether an application is likely to be worth pursuing given your level of support needs.
The NDIS add-on is $600 and produces a separate report. Access and funding are decided by the NDIA, not by us.
