Adult autism assessment in Brisbane
Adult autism assessment in Brisbane: who assesses, what it costs in 2026, what to expect, and how to find neurodivergent-affirming practitioners in Brisbane while you decide.
In brief. Adult autism assessment in Brisbane is usually done privately by a psychologist or psychiatrist experienced in adult presentations, over two to four appointments, at $1,200 to $2,500 in 2026. There is no Medicare item covering the assessment as a whole. Inner Help does not yet assess autism; we list practitioners in Brisbane who do, and support is available now without a diagnosis.
Who assesses adults in Brisbane
Clinical and registered psychologists with adult autism experience conduct most assessments and write the detailed reports used for NDIS, study and workplace adjustments. Psychiatrists assess autism within a broader psychiatric assessment and are the right choice when medication questions or complex co-occurring conditions are prominent. Brisbane assessors are concentrated in the inner suburbs and the Gold Coast, with many offering telehealth across Queensland.
What it costs and involves
Expect a developmental history, standardised measures (AQ, RAADS-R, often the CAT-Q for masking), input from someone who knew you as a child where possible, and a diagnostic letter or full report. Typical fees are $1,200 to $1,800 for a psychologist-led assessment with a letter, $1,650 to $2,500 with a comprehensive report, and $2,200 to $2,600 for combined autism and ADHD assessment.

Frequently asked questions
Do I need a GP referral for autism assessment in Brisbane?
Not for a psychologist. You need one to see a psychiatrist and for any Medicare rebate on consultations.
How long is the wait?
Two to six months for popular Brisbane practices; telehealth assessors elsewhere in QLD often have shorter waits.
Will Inner Help offer autism assessment?
Not yet. Our GP-led assessment pathway begins with ADHD and will be published before it opens.
