Adult ADHD Test and Assessment Online in Australia
Published on 12 November 2026 at 6:58 pm
Suspect ADHD? Start with a GP. See an AHPRA-registered doctor online from $49 — screening, a mental health check, and a specialist referral if needed, all from home.
Searches for adult ADHD have exploded in Australia over the past few years, and for good reason: more adults — especially women and people diagnosed in their 30s, 40s and beyond — are realising that lifelong struggles with focus, organisation and impulsivity might have a name. But between viral self-tests, online clinics and long specialist waitlists, it is hard to know where to actually start.
This guide explains the real pathway in Australia: what an online GP can do, what the formal assessment involves, what it costs, and what telehealth can and cannot do when it comes to ADHD.
The Quick Answer
In Australia, only a psychiatrist (or paediatrician, for under-18s) can formally diagnose ADHD and initiate stimulant medication. A GP cannot do this alone.
But a GP is still the right first step: they screen your symptoms, rule out look-alike conditions (anxiety, depression, sleep problems, thyroid issues), and give you a referral to a psychiatrist — which you need to claim Medicare for specialist appointments.
You can do the first step online: an AHPRA-registered telehealth GP consult is $49, and the referral is $25.
The standard screening tool is the ASRS v1.1 — free, six questions, and widely used by GPs as a first check.
If you already have a diagnosis and a stable prescription, a telehealth GP may be able to help coordinate ongoing care — but stimulant prescriptions always sit under specialist oversight.
Do you actually have ADHD? Common signs in adults
Adult ADHD looks different from the childhood stereotype. It is not just hyperactivity — many adults, particularly women, present as quietly inattentive rather than visibly restless. The patterns that matter most are persistence and pervasiveness: these traits have been there since childhood and show up across work, study and relationships.
✓Attention: difficulty sustaining focus on uninteresting tasks, losing things, unfinished projects piling up, drifting off mid-conversation
✓Executive function: chronic procrastination, time blindness, difficulty prioritising, forgetting appointments and deadlines
✓Impulsivity and restlessness: interrupting, impulsive spending or decisions, inner restlessness even when sitting still
One caution: none of these are unique to ADHD. Anxiety, depression, poor sleep, thyroid problems and even iron deficiency can mimic every one of them — which is exactly why a GP screen comes before any diagnosis.
Step 1: The GP screen (this is where you start)
A telehealth GP appointment works well for this first step. Your doctor will:
1Take a structured history — childhood behaviours, school reports, how symptoms show up now
2Run a screening tool such as the ASRS v1.1 (six questions, takes two minutes)
3Screen for conditions that look like ADHD — anxiety, depression, sleep disorders, substance use — and address them if found
4Write a specialist referral to a psychiatrist, so you can claim the Medicare rebate for assessment
If anxiety or low mood is part of the picture — very common alongside ADHD — your GP can also prepare a Mental Health Care Plan, which is bulk-billed through this practice and unlocks subsidised psychology sessions.
Step 2: The formal assessment
The diagnosis itself is made by a psychiatrist, usually after a structured clinical interview (often using DIVA-5 or similar tools), sometimes with input from family or old school reports. Sessions typically run one to three hours.
Your options:
•Telehealth psychiatry — assessment from home; waitlists vary but are often shorter than metro in-person clinics, and appointments are Medicare-rebatable with a referral
•Private psychiatrist (in person or telehealth) — typically $600–$1,500 out of pocket for a full assessment depending on the provider and Medicare safety net position
•Public system — low or no cost, but waitlists can be long and usually require significant functional impairment
Why the GP referral matters: without one, you generally cannot claim Medicare for the psychiatrist appointment. The referral is the cheapest ($25) and fastest part of the whole pathway — get it first.
Step 3: Treatment after diagnosis
ADHD treatment typically combines medication with skills-based support (coaching, CBT, structure strategies). The two main medication families:
✓Stimulants (methylphenidate, lisdexamfetamine) — the most evidence-backed option, but they are Schedule 8 medicines. Your psychiatrist initiates them; your GP may then continue prescriptions under a shared-care arrangement, depending on state rules and the specialist's plan.
✓Non-stimulants (atomoxetine and others) — an alternative where stimulants are unsuitable; prescribing rules are less restrictive.
What telehealth can't do: no legitimate online service — including this practice — will diagnose ADHD or start stimulant medication from a single online questionnaire. If a website offers same-day ADHD diagnosis and a stimulant script without a psychiatrist assessment, walk away. That is not just risky; stimulant prescribing outside the proper pathway is illegal in every Australian state.

Frequently asked questions
No. A formal ADHD diagnosis must be made by a psychiatrist (or paediatrician for children). A GP's role is screening, ruling out look-alike conditions, referring you for assessment, and supporting ongoing care after diagnosis.
Only through the proper pathway. Stimulant medication is Schedule 8 — a psychiatrist must assess you and initiate treatment, after which a GP may continue prescriptions under specialist oversight. Any online service offering a diagnosis and stimulant script from a questionnaire alone is not operating legally or safely.
Yes — the ASRS v1.1 (Adult ADHD Self-Report Scale) is free, takes about two minutes, and is the same screening tool many GPs start with. It will not diagnose you, but a positive screen is a solid reason to book a GP consult and discuss a referral.
Private assessments typically cost $600–$1,500 out of pocket, with a Medicare rebate available if you have a GP referral. Telehealth psychiatry often has shorter waitlists. Public assessment is low or no cost but usually has long waitlists and stricter eligibility.
Yes, if you want the Medicare rebate. A GP-issued specialist referral is required to claim subsidised psychiatric appointments — and a telehealth GP can provide one online for $25.
