Have you always wondered why some things feel harder for you? Some adults start asking about ADHD after a child’s assessment. Others start after a comment from a friend. However the question came up, it’s fine to want to understand it. You don’t need to be sure of anything to read on.
An adult ADHD assessment in Australia can help clarify whether ADHD fits your experience. This guide covers what happens in one, what it costs, who can diagnose and prescribe, and what happens after. Figures are dated, so check them again if you’re reading this much later.
What is an adult ADHD assessment?
An adult ADHD assessment is a structured process run over more than one appointment. A clinician gathers information about your life now and your life as a child. They weigh it against the diagnostic criteria for ADHD. They also look at what else could explain what you’ve noticed. There’s no single test, scan or blood test that decides it.
The Australian guideline for ADHD says a diagnosis needs a thorough assessment. That includes looking at other conditions that can overlap. It also says the difficulties must affect everyday life, such as work, study, relationships or running a household. And they need to show up in more than one setting (AADPA guideline, 2022).
What happens during an adult ADHD assessment?
Most adult assessments follow the same broad steps: an interview, rating scales, information from someone who knows you, a look at other explanations, then a feedback session and a written report. The order and number of appointments vary between clinicians.
A clinical interview
This is usually the longest part. Your clinician asks how things show up in your day. Think work, money, time, memory, relationships and rest. They’ll ask about childhood and school too. ADHD starts in childhood, even when it’s first noticed in adulthood. Old school reports can help if you still have them.
Rating scales
You’ll fill in standard questionnaires. These compare your answers with large groups of other adults. That gives your clinician a measure to work with, beyond their own impression.
Information from someone who knows you
With your consent, your clinician may ask a partner, parent or sibling to fill in a form. Someone who knew you as a child is especially useful. Everyone has blind spots about themselves. A second view helps fill them in.
A look at other explanations
Sleep problems, anxiety, low mood, burnout and some physical health issues can all affect focus and memory. A careful assessment spends time on these. It’s one reason an assessment takes more than one appointment.
Feedback and a written report
At the end, your clinician meets with you to go through what they found. You’re welcome to ask questions. You then receive a written report. It sets out what was gathered, what it points to, and suggested next steps.
How long is the wait for an adult ADHD assessment?
In a national study published in 2026, clinicians quoted adults an average wait of just over 10 weeks for a first ADHD assessment appointment. Some quoted up to a year. The calls were made in 2024. The quoted wait was shorter for psychologists (about 5.6 weeks on average) than for psychiatrists (about 16 weeks).
That figure comes from a University of Wollongong “secret shopper” study. Researchers contacted 736 psychologists, psychiatrists and paediatricians across Australia, posing as people seeking an assessment. Only 59% responded within two calls. Of those, about half offered an ADHD assessment (Journal of Attention Disorders, February 2026; UOW summary, 2026).
As lead researcher Clare O’Toole put it: “Accessibility starts from: can I even get someone on the phone?”
The assessment itself then takes more than one appointment. How many depends on the clinician and on what comes up along the way.
How much does an adult ADHD assessment cost in Australia?
The same study found a full adult assessment cost about $1,400 on average in 2024, before any rebates. Some cost close to $4,000. Psychologists charged less for the first appointment but more in total. Psychiatrists charged more up front but less in total.
Here are the study’s 2024 averages for adults, before rebates:
| Clinician | First appointment | Full assessment |
|---|---|---|
| Psychologist | $276 | $1,573 |
| Psychiatrist | $731 | $1,127 |

When you compare prices, ask what the fee covers. Some quotes cover the first appointment only. Others include the interview, the scales, the feedback session and the report. The total is the number that matters.
Is an ADHD assessment covered by Medicare?
No. Our adult ADHD assessment doesn’t attract a Medicare rebate. You pay the full fee. If you have private extras cover, ask your fund whether it pays anything towards an assessment.
A few other points are worth knowing (figures as at 1 July 2026):
- Psychiatrist appointments may attract a Medicare rebate if you have a referral and meet Medicare’s rules. The gap can still be large.
- Psychology sessions after an assessment may attract a rebate under a Mental Health Treatment Plan, if you meet Medicare’s rules. The rebate is $101.55 for a registered psychologist and $149.05 for a clinical psychologist, for a session of 50 minutes or more. It covers up to 10 individual sessions a calendar year.
- Treatment Plans now come from your usual GP. Since 1 November 2025, the plan must come from your usual GP or MyMedicare practice.
Our fees and Medicare rebates page keeps the current figures in one place.
How much is an ADHD assessment at The Symphony Clinic?

Who can diagnose ADHD in adults, and who can prescribe?
In Australia, psychologists and psychiatrists can assess and diagnose ADHD in adults. Psychologists can’t prescribe. Psychiatrists can. In some states, GPs can now diagnose and prescribe for adults too. The rules differ by state and are changing fast.
Here’s where things stand as at late September 2026:
- Queensland. Since 1 December 2025, GPs can start, change and continue ADHD medicine for adults (Queensland Government). The state has not made extra training compulsory (Medical Republic).
- South Australia. Since 28 February 2026, GPs who have finished a state training program can diagnose ADHD in adults and in children aged 8 and over (SA Health).
- New South Wales. GP training began in March 2026. GPs who finish it can diagnose ADHD. Training is being offered first to GPs in areas of greatest need (NSW Health).
- Victoria. The first 150 GPs are training across September and October 2026. They’ll be able to diagnose ADHD in adults and in children aged 6 and over. The state says prescribing still depends on regulatory changes (Victorian Department of Health, updated 28 August 2026).
- Western Australia. By August 2026, 64 GPs had finished ADHD training. Once authorised, they can assess and manage uncomplicated ADHD in people aged 10 and over (WA Government).
- Other states and territories. Check your state or territory health department for the latest.
Not every GP in these states offers ADHD care. Ask your own GP whether they do. If they don’t, they can refer you to a GP or psychiatrist who does.
Our clinicians don’t prescribe. We’re a psychology and counselling clinic. If you’d like to talk about medicine, your report can be shared with your GP or a psychiatrist. Your clinician can talk with you about who to share it with.
What happens after an ADHD assessment?
An assessment usually ends with a feedback session and a written report. With your consent, the report can be shared with your GP or a psychiatrist. What you do next is your choice, and you can take your time. It depends on what the assessment found and what you want help with.
Common next steps include:
- Taking the report to your GP. Your GP can talk through options with you. In some states they may be able to prescribe, if appropriate. Or they may refer you on.
- Seeing a psychiatrist. A psychiatrist can review the report and decide whether medicine is appropriate for you. Some psychiatrists may want to do their own assessment. Ask before you book.
- Psychology sessions. Some people want support with the day to day. That can mean planning, routines, work, or the feelings that come with a new explanation. Sessions may attract a Medicare rebate under a Treatment Plan, if you meet Medicare’s rules.
- Looking into other explanations. If something else came up, such as sleep or low mood, the report may suggest what’s worth exploring.
What if the assessment doesn’t point to ADHD?
An assessment can clarify whether ADHD fits your experience. It can’t promise an answer either way. Either way, you’ll get a written report that sets out what was found.
If the criteria are met, the report explains how the clinician reached that view. You can share it with your GP, a psychiatrist or your workplace, if you choose.
If the criteria aren’t met, the process still counts. The report will describe what was found. It may point to other things worth looking at, such as sleep, stress or mood. For some people, that’s the more useful document.
Everyone’s assessment is different. The findings depend on your history and circumstances.
How do you prepare for an adult ADHD assessment?
If it helps, gather a few things before your first appointment. None of them are essential. Each one helps your clinician build a clearer picture. Bring what you can and don’t worry about the rest.
- School reports or old records, if you still have them.
- A rough timeline of when things felt hardest, and what was going on then.
- The name of someone who knew you as a child and could fill in a form.
- A list of anything else being looked at or treated, including sleep.
- Notes on how things show up now, at work and at home.
For a video appointment, find a quiet, private spot with a steady connection. A phone appointment works too.
