What an ADHD assessment costs in Australia
The honest version: for most adults it is fully out of pocket, the range between providers is wide, and the headline price is often not the whole price. Here is what drives the number and what to check before you pay anyone.
What we will not do on this page. We are not going to publish a table of what other clinics charge. We do not have verified current pricing for them, prices move, and a made-up range would be worse than useless when you are about to spend four figures. What we can do is explain exactly what creates the difference, and give you the questions that expose it.
Why there is no Medicare item for it
This is the single fact that explains most of the cost, and almost nobody states it plainly.
There is no Medicare Benefits Schedule item for an adult ADHD assessment performed by a psychologist. That is not a clinic policy and it is not something a provider can work around — it is how the schedule is written. The relevant items were built around children and around medical specialists. So when an adult sees a psychologist for a diagnostic assessment, the whole fee sits with the patient.
The Senate Community Affairs References Committee looked at exactly this. Its inquiry into assessment and support services for people with ADHD drew around 700 submissions, and it identified the high cost of services — including insufficient coverage under Medicare, the PBS and the NDIS — as a primary barrier, alongside long waits and thin coverage outside the capitals. If the system feels like it was not designed for you, that is a documented finding rather than a feeling.
The two situations where Medicare does contribute
Both involve a psychiatrist, and both need a referral from your GP. You can verify every figure below yourself in the MBS item search, linked at the bottom of this page.
| Item | What it is | Schedule fee | Benefit at 85% |
|---|---|---|---|
| 291 | A psychiatrist assessment and management plan, any age, expected to be a single attendance, with the patient then managed by the referring GP | $549.90 | $467.45 |
| 289 | A psychiatrist attendance for a patient under 25 with a complex neurodevelopmental disorder, producing a treatment plan shared with the GP and allied health | $320.55 | $272.50 |
Current as at 21 September 2026. Schedule fees change with the annual update, and what a psychiatrist charges is usually more than the schedule fee — the benefit is a contribution, not a cap on what you are billed.
The rebate is not the saving it looks like. A rebate of $467.45 against a psychiatrist fee that may be well above the schedule fee still leaves a gap, and psychiatrist waits for adult ADHD are long in most of the country. For a lot of people the psychologist-led route is faster and costs less in total even with no rebate at all. Which one is better depends on what you need the report to do — and if medication is the goal, see the state-by-state section below.
Is there a bulk-billed ADHD assessment?
Realistically, no — not for an adult, not as a standard offering, and anyone implying otherwise is worth a second look.
Bulk billing means the provider accepts the Medicare benefit as full payment. That requires a Medicare item to bill against. As above, for an adult psychologist-led ADHD assessment there is no such item, so there is nothing to bulk bill. The mechanism is missing, not the goodwill.
What does genuinely exist:
- Bulk-billed GP appointments at practices that bulk bill. Your GP can discuss symptoms, look at the obvious differentials, and refer you. That part can cost you nothing. The assessment itself is the part that is not covered.
- Rebated psychiatrist attendances under items 289 and 291 above. A rebate, not bulk billing — you pay the fee and claim part of it back, unless that particular psychiatrist bulk bills, which is uncommon for adult ADHD.
- Public mental health services, which exist but are configured around acute and severe mental illness. Adult developmental assessment is not what they are resourced to do, and most adults who ask are redirected. We would rather say that than let you wait months to find out.
- Under 25, item 289 can unlock a limited number of rebated allied health sessions as part of a treatment plan. Worth asking your GP about specifically if it applies to you.
Be careful with "free" and "bulk billed" ADHD assessment advertising. Usually one of three things is happening: the free part is a short screening call rather than the assessment, the bulk-billed part is a GP appointment attached to a paid assessment, or the fee appears later as a separate report charge. None of those are necessarily dishonest — but read what is actually included before you book.
What actually drives the difference between providers
When two quotes differ by a thousand dollars, it is almost always one of these five things rather than one being a rip-off.
Who does the assessment. A psychiatrist-led assessment costs more than a psychologist-led one, because it is a medical specialist's time. It also attracts a rebate and can lead directly to a prescription. A psychologist-led assessment costs less and, for everything except medication, produces a report that is accepted just as widely.
How long it actually takes. A diagnostic assessment that meets the national guideline involves a developmental history reaching back to childhood, standardised rating scales, and a structured interview against the diagnostic criteria. That is hours, not a single appointment. A much cheaper quote sometimes means much less time, and time is where the accuracy is.
Whether the report is included. This is the most common surprise. Ask explicitly whether the written report is in the quoted fee, and what happens if you later need it rewritten for a different purpose.
Whether anyone reviews it. Some services have a second clinician review the formulation before the report is released. It costs more and it is the difference between a report that holds up and one that gets rejected by the body you needed it for.
What happens afterwards. A cheap assessment that leaves you holding a report with nowhere to take it is not cheap. If medication is the goal, the pathway to a prescriber is part of the product.
The questions that expose the real price
Ask any provider these before you pay a deposit. Ours included.
- Is the written report included in the fee, or billed separately?
- Who will conduct the assessment, what is their registration, and can I look them up?
- How many hours of clinical contact is that fee buying?
- If I do not meet the criteria, what happens — is the fee still payable?
- If I need the report for the NDIS, Centrelink, my employer or my university, will it be written to that standard?
- If I want to explore medication, who prescribes, and what does that appointment cost?
- Is there a charge for follow-up questions, or for a copy of my own records?
On that fourth one. An assessment is not a purchase of a diagnosis. Any provider whose fee is implicitly contingent on giving you the answer you came for has a problem, and so does their report. The fee buys the work and an honest opinion.
The cost after the diagnosis, which people forget
The assessment is one line in the budget. If medication is why you are doing this, there are two more, and how big they are depends on which state you live in.
A psychologist cannot prescribe stimulant medication anywhere in Australia. Who can start you on it is set by your state or territory, and four states changed their rules between late 2025 and now. In Queensland and Western Australia, appropriately trained GPs can now handle far more of it, which can remove a psychiatrist appointment from your path entirely. In Victoria and South Australia, a psychiatrist is realistically still in the picture for most adults.
That difference is worth hundreds of dollars and often months of waiting, and it has nothing to do with who assessed you.
Then there is the medication itself. Most ADHD stimulants are PBS-subsidised when prescribed for an approved indication, so the ongoing cost is usually modest compared with the assessment — but check with the prescriber rather than assuming.
What we charge, and why we publish it
Most clinics will not put a number on a public page. We do, because the alternative is making you fill in a form to find out whether you can afford something.
An adult ADHD assessment with us is $1,650 including the written report. Autism is the same. Assessing both together is $1,950 rather than $3,300, because the developmental history only has to be taken once. Cognitive and adaptive assessment starts at $1,450 and is quoted individually, because which measures are needed varies.
Every fee includes the report. There is no booking fee and no separate charge for the document you came for. The full breakdown, including how the Medicare items above apply to you, is on the pricing page.
Common questions
How much does an ADHD assessment cost in Australia?
For an adult, expect a four-figure out-of-pocket cost in the private system, because there is no Medicare item for a psychologist-led adult ADHD assessment. Ours is $1,650 including the report. The spread between providers is driven by who conducts it, how many hours it takes, and whether the written report is included — see the section above on what actually drives the difference.
Can I get an ADHD assessment bulk billed?
Realistically no, for an adult. Bulk billing requires a Medicare item to bill against, and there is no item for an adult psychologist-led ADHD assessment. Bulk-billed GP appointments and rebated psychiatrist attendances under items 289 and 291 are the parts of the pathway where Medicare does contribute.
Does Medicare cover an ADHD assessment?
Not for an adult seeing a psychologist. It contributes in two situations, both involving a psychiatrist and a GP referral: item 291 returns $467.45 at the 85% benefit, and item 289 returns $272.50 for patients under 25 with a complex neurodevelopmental disorder. Both are contributions toward the fee rather than the full amount.
Why is an adult assessment more expensive than a child's?
Mostly because of the Medicare items. Paediatric pathways have items attached to them; adult psychologist-led assessment does not. The clinical work is comparable and in some ways harder in adults, because the childhood evidence has to be reconstructed decades later.
Is a cheaper assessment worse?
Not automatically, but ask what is being left out. The three things that most often explain a much lower price are fewer hours of clinical contact, no written report included, and no second-clinician review. Any of those can be fine depending on what you need. All three together usually is not.
What if I cannot afford it right now?
Start with your GP, which at a bulk-billing practice costs nothing. A GP can look at the differentials that commonly imitate ADHD — sleep, thyroid, iron, depression, anxiety — and some of those are both cheaper to investigate and genuinely worth ruling out first. Our free ADHD test is a three-minute way of deciding whether the conversation is worth having at all.
