If you’ve spent years wondering why certain things feel harder than they should — staying focused, starting tasks, finishing what you begin, remembering appointments, or sitting still through a meeting — you may have started to wonder about ADHD. Attention-deficit/hyperactivity disorder in adults is far more common than once thought, and for many people, understanding it later in life brings a profound sense of clarity. Here’s how the diagnosis process works in Australia and what to expect along the way.
What Is Adult ADHD?
ADHD is a neurodevelopmental condition that affects attention, impulse control, and in some people, activity levels. In adults, it often looks different from the stereotype of a hyperactive child. Adults with ADHD may struggle with organisation, time management, sustained attention on unstimulating tasks, forgetfulness, restlessness, and emotional regulation. Many are high-achieving and creative, but living with an exhausting amount of mental effort to stay on top of daily life.
Crucially, ADHD symptoms must have been present since childhood — even if they weren’t recognised at the time. A thorough assessment will always explore your developmental history, not just your current difficulties.
Step 1: Start With Your GP
The pathway to an ADHD diagnosis in Australia begins with your GP. Book a consultation and describe what you’ve been experiencing. You don’t need to have it all figured out — simply explaining that you’ve been struggling with attention, focus, or organisation and that you’d like to explore whether ADHD might be involved is enough.
Your GP will ask some initial questions and, if they agree that further assessment is warranted, will provide a referral to a psychiatrist. A GP referral is essential — it allows you to access Medicare rebates for your psychiatric consultations. Without one, you would need to pay the full fee privately.
Step 2: The Psychiatric Assessment
A comprehensive ADHD assessment is conducted by a psychiatrist — a medical specialist qualified to diagnose and treat the condition. The assessment typically involves one or more extended consultations and covers:
- A detailed developmental history — what you were like as a child, including school reports or family recollections where available.
- Your current symptoms — how attention, organisation, impulsivity, and restlessness affect your daily life now.
- Your broader mental health history — ADHD frequently coexists with anxiety, depression, or other conditions, and these need to be understood.
- Screening questionnaires — validated tools such as the ASRS (Adult ADHD Self-Report Scale) are often used as part of the assessment.
- Collateral information — where possible, input from a partner, parent, or close friend who can describe how they’ve observed you over time.
You can get a head start by completing our free ADHD self-assessment (ASRS) before your appointment. The results aren’t a diagnosis, but they can help you reflect on your experiences and provide useful information to discuss with your psychiatrist.
Step 3: Diagnosis and Discussion
After gathering a thorough history, your psychiatrist will discuss their assessment with you. If ADHD is present, they’ll explain what type (primarily inattentive, primarily hyperactive-impulsive, or combined) and how it’s affecting you. They’ll also consider whether any other conditions are contributing to your difficulties.
If a diagnosis is made, your psychiatrist will outline a management plan. Treatment for adult ADHD often involves a combination of strategies, which may include psychological approaches, practical strategies for organisation and routine, and, where clinically appropriate, medication. Every plan is tailored to the individual, and nothing happens without your informed agreement.
Why a Specialist Assessment Matters
ADHD shares symptoms with several other conditions — anxiety, depression, sleep disorders, thyroid dysfunction, and the effects of chronic stress, to name a few. This is why a careful, comprehensive assessment by a psychiatrist is so important. A diagnosis isn’t about labelling; it’s about understanding your experience accurately so that the right supports can be put in place.

How Telehealth Makes ADHD Assessment Accessible
For many adults wondering about ADHD, finding a psychiatrist with availability — particularly one experienced in adult ADHD — can involve long waitlists. Telehealth psychiatry changes this. Through secure video consultations, you can access a FRANZCP-qualified psychiatrist from anywhere in Australia, without travelling or sitting in a waiting room. The assessment is just as comprehensive, and for many people, being in their own home makes it easier to be open and reflective.
What to Bring to Your Appointment
To help your assessment go smoothly, it’s useful to gather a few things in advance:
- Any old school reports or reports cards, if you have them.
- A brief written summary of what you’ve been experiencing and for how long.
- Notes from your GP and your referral letter.
- A list of any medications you’re currently taking.
- The results of your ASRS self-assessment, if you’ve completed one.
If you’re ready to take the next step, talk to your GP about a referral, then get in touch to arrange a telehealth assessment. Clarity about what you’ve been living with can be genuinely life-changing.
