Undergoing an adult ADHD assessment is a significant step toward understanding your brain and improving your daily life. In Australia, the path to a formal diagnosis usually involves a mix of general practitioners, psychiatrists, and psychologists. Because the process is thorough and requires a look back at your entire life, being well-prepared can make the experience less stressful and more productive. This guide explains how to get ready for your evaluation and what to expect from psychiatry services in Australia.
Understanding the Assessment Process in Australia
The journey usually begins in a GP’s office. Your doctor will talk to you about your concerns and, if appropriate, write a referral to a specialist. While psychologists can conduct assessments and provide behavioural support, a psychiatrist is typically required if you are seeking a medical diagnosis and wish to explore medication as a treatment option.
The Role of Psychiatry Services in Australia
Psychiatrists are medical doctors who specialise in mental health. When you seek an adult ADHD assessment through psychiatry services in Australia, the focus is on clinical history, symptom patterns, and ruling out other conditions that might look like ADHD, such as anxiety or mood disorders. Because ADHD is a neurodevelopmental condition, the specialist must establish that symptoms were present before the age of 12, even if you weren’t diagnosed as a child.
Why the Process is Detailed
Australian clinical guidelines require a comprehensive evaluation to ensure accuracy. This isn’t a simple “tick-the-box” exercise. It involves a clinical interview, various rating scales, and often “collateral information”—evidence from people who knew you as a child or see how you function now. This thoroughness ensures that your treatment plan is tailored specifically to your needs.
Essential Documentation to Gather
One of the most helpful things you can do before your appointment is to collect your “paper trail.” Since the assessment looks at your history, having physical evidence of your past challenges is invaluable for the clinician.
School Reports and Childhood Records
If you can find them, primary and secondary school reports are goldmines for ADHD assessments. Look for teacher comments such as “has great potential but needs to focus,” “frequently loses equipment,” “talks too much in class,” or “is easily distracted.” These comments provide objective evidence of childhood symptoms that you might not remember clearly yourself.
Previous Medical and Mental Health Records
If you have seen other specialists, psychologists, or counsellors in the past, try to get copies of those records. This helps the psychiatrist understand your mental health journey and see if other treatments were tried previously. It also helps them identify any “co-occurring” conditions, which are common with ADHD.
Current Symptom Logs and Work Examples
Keep a journal for a week or two before your assessment. Note down times when you felt overwhelmed, forgot an appointment, or struggled to start a task. If you have performance reviews from work that mention issues with time management or attention to detail, these are also useful to bring along.
Preparing Your Personal History

During the clinical interview, you will be asked many questions about your life. It can be hard to remember everything on the spot, so writing down some notes beforehand can keep you on track.
Identifying Patterns in Daily Life
Think about how your symptoms affect different areas of your life today. Do you struggle with household chores, paying bills on time, or maintaining social connections? Being able to give specific examples of how these challenges impact your “functioning” is a key part of the diagnostic criteria.
Talking to Family and Long-Term Friends
If you feel comfortable, talk to your parents, siblings, or childhood friends. Ask them what you were like as a child. Were you constantly on the move? Did you lose your jumper every week? Their perspectives can fill in the gaps in your own memory and provide the “collateral” evidence that psychiatrists often look for.
Managing the Logistics of Your Appointment
The practical side of an adult ADHD assessment in Australia can be complex, especially regarding costs and waiting times. Knowing what to expect financially and timing-wise can help you manage the wait.
Costs and Medicare Rebates
Assessments can be expensive, often ranging from $600 to over $2,000 depending on the specialist and the number of sessions required. While a Mental Health Care Plan from your GP can help with the cost of seeing a psychologist for therapy, it generally does not cover the full cost of a formal ADHD assessment. However, seeing a psychiatrist with a valid GP referral usually allows you to claim a Medicare rebate for the consultation fees. It is a good idea to ask the clinic for a clear breakdown of fees and expected rebates before you book.
Waiting Times and Telehealth Options
Waitlists for psychiatry services in Australia can be long, sometimes stretching several months. Some clinics offer telehealth appointments, which can be a more accessible option if you live in a regional area or if local specialists are fully booked. Check if your chosen specialist requires you to complete pre-assessment questionnaires online before your first meeting, as this can speed up the process.
What to Expect During the Clinical Interview
The interview is the heart of the assessment. It is usually a conversation where the psychiatrist gets to know you and your history.
The DIVA-5 and Other Rating Scales
Many Australian clinicians use the DIVA-5 (Diagnostic Interview for ADHD in adults). This is a structured interview that goes through the criteria for ADHD and asks for examples from both your childhood and your current adult life. You might also be asked to fill out the ASRS (Adult ADHD Self-Report Scale), which is a shorter screening tool used to gauge the frequency of your symptoms.
Discussing Treatment Options
If a diagnosis is confirmed, the final part of the assessment process involves discussing what comes next. This might include:
- Medication: Exploring stimulant or non-stimulant options.
- Psychological Support: Working with a psychologist on “top-down” strategies like Cognitive Behavioural Therapy (CBT).
- ADHD Coaching: Practical help for time management and organisation.
- Lifestyle Adjustments: Looking at sleep, diet, and exercise.
Tips for the Day of Your Assessment
On the day of your appointment, try to give yourself plenty of time. If you are doing a telehealth session, make sure you are in a quiet, private space where you won’t be interrupted.
Be Honest and Specific
There is no need to “mask” or try to appear more organised than you are during the assessment. The clinician needs to see the real you to make an accurate diagnosis. If you find it hard to answer a question, it is okay to say so. Use your notes if you get stuck or if your mind goes blank.
Bring a Support Person

Many clinics allow you to bring a partner or a close friend to the appointment. They can provide additional information and help you remember what was discussed afterward. Having a second pair of ears is often very helpful when absorbing a lot of new information.
An adult ADHD assessment is a collaborative process between you and your healthcare team. By gathering your records, reflecting on your history, and understanding the role of psychiatry services in Australia, you can approach your appointment with confidence.
