In Australia, ADHD is formally diagnosed by a medical doctor with the right training — usually a psychiatrist, or a paediatrician for children and teenagers. A registered psychologist carries out the in-depth assessment and contributes crucial findings, but the medical diagnosis and any prescribing are a doctor's responsibility. Your GP supports referrals and ongoing shared care.
If that sounds like more than one person, it is — and that's a good thing. ADHD care in Australia is usually a small team working together, each doing the part they're trained for. This guide explains who does what, why the medical diagnosis sits with a doctor, and how the pieces fit together in a telehealth pathway from home.
Who can diagnose ADHD in Australia?
The practitioners who can make a formal medical diagnosis of ADHD in Australia are psychiatrists and paediatricians, because both are medical doctors with specialist training. A psychiatrist commonly diagnoses adults and older teens, while a paediatrician often diagnoses children and younger adolescents. Psychologists assess in detail and can identify ADHD presentations, but the medical diagnosis used for prescribing is a doctor's role.
Here is how the main roles break down:
- Psychiatrist — a medical doctor specialising in mental health, who confirms a medical diagnosis and looks after treatment, including medication where it is clinically appropriate.
- Paediatrician — a medical doctor specialising in children's health, who commonly diagnoses and manages ADHD in children and younger teens.
- Registered psychologist — leads the comprehensive assessment, gathers detailed history and standardised information, and identifies whether an ADHD presentation is likely, feeding directly into the medical decision.
- GP (general practitioner) — your first point of contact, who provides referrals and is part of ongoing shared care with your specialist.
Why is the diagnosis a doctor's responsibility?
ADHD is a medical condition, and confirming it for the purpose of treatment — including medication where clinically appropriate — is a medical decision. In Australia, prescribing for ADHD is regulated, and only a medical practitioner can take on that responsibility. That's why a psychiatrist or paediatrician confirms the diagnosis even when a psychologist has done much of the detailed assessment work.
This isn't about ranking one profession above another. It's about each clinician working within their scope of practice. A psychologist's in-depth assessment is often the backbone of the whole process; the doctor brings the medical lens, considers your wider health, and takes responsibility for any prescribing decision.
What does a psychologist contribute to an ADHD diagnosis?
A registered psychologist usually leads the most detailed part of the process: the comprehensive assessment. They build a careful picture of your experiences across your whole life, not just how you feel today, and that picture is essential to a sound diagnosis.
A psychologist's assessment typically includes:
- A thorough history of your difficulties — childhood, school or work, relationships, and current daily life.
- Standardised questionnaires completed by you, and sometimes by someone who knows you well.
- A careful look at other things that can mimic or overlap with ADHD, such as sleep, anxiety or mood.
- A clear written summary of findings that informs the medical diagnosis and can be shared with your GP and specialist.
How does the multidisciplinary team work together?
Good ADHD care joins these roles into one coordinated pathway rather than leaving you to manage separate, disconnected appointments. In a telehealth model, a registered psychologist usually leads the in-depth assessment, a psychiatrist confirms the diagnosis and looks after treatment where it is clinically appropriate, and your GP shares ongoing care close to home.
The Australian Evidence-Based Clinical Practice Guideline for ADHD, developed by AADPA, supports this kind of coordinated, multidisciplinary approach. With your consent, the people involved in your care keep each other in the loop so everyone is working from the same picture — which is exactly what a careful diagnosis and treatment plan should look like.
Can I do all of this online by telehealth?
Yes. Assessment, diagnosis, treatment and ongoing reviews can all happen by secure video, from home, anywhere in Australia. Telehealth is a well-established way to deliver psychology and psychiatric care, and many people find it easier to talk openly from their own space.
At Seen ADHD, the in-depth assessment is psychologist-led, with psychiatrist input where appropriate, and your GP is part of shared care. As a guide to what's involved, an Initial Telehealth Assessment starts from $149, the core Seen ADHD Pathway is $995 for a two-hour psychologist-led assessment with psychiatrist input where appropriate, and ongoing Treatment & Review care starts from $1,495. Rebates are situational and never guaranteed, so it's worth confirming what applies to you with your GP.
What if I don't meet the criteria for ADHD?
An assessment is designed to give you clarity, not a predetermined answer. Not everyone who is assessed will meet the criteria for ADHD, and an honest "no" is a valid and genuinely useful outcome — it often points to support that fits you better, such as help with sleep, anxiety or mood.
