Understanding ADHD and why diagnosis matters
If you’ve been wondering whether you or your child might have ADHD, you’re not alone. At Reimagine, we hear from families and individuals every week who are navigating the early stages of this journey—often overwhelmed, confused, and unsure where to start.
ADHD (Attention-Deficit/Hyperactivity Disorder) is a neurodevelopmental condition that affects people differently. For some, it shows up as endless forgetfulness or emotional rollercoasters. For others, it might be intense restlessness or a brain that just won’t slow down. ADHD can affect thinking, communication, behaviour, and emotional regulation, influencing many aspects of daily life.
Whether you’re a parent seeing patterns in your child, or an adult realising, “This explains a lot,” getting a diagnosis can be the first step toward understanding how your brain works—and what support can actually help.
But let’s be honest. It can also be expensive, confusing, and filled with jargon. That’s why we’re breaking it down: the real costs, rebates, who does what, and why diagnosis is only the beginning.
Receiving an ADHD diagnosis can be life changing for individuals and families, offering clarity and a path forward.
Recognising ADHD symptoms: What to look for
Recognising the signs of attention deficit hyperactivity disorder (ADHD) is often the first step toward seeking meaningful support and a thorough assessment. ADHD symptoms can look different from person to person, but they generally fall into two main categories: inattention and hyperactivity/impulsivity.
For many adults, ADHD symptoms may have been present since childhood but were overlooked or misunderstood. Common signs include persistent forgetfulness, difficulty focusing on tasks, trouble organising daily activities, and a tendency to lose things.
Hyperactivity might show up as restlessness, fidgeting, or feeling unable to relax, while impulsivity can lead to making decisions without thinking them through or interrupting others in conversation.
These symptoms often begin before the age of 12 and can continue throughout life, affecting relationships, work, and daily functioning. If you notice these patterns in yourself or a loved one, it’s important to seek a professional assessment.
A thorough assessment by a qualified clinician can help clarify whether these symptoms are due to ADHD or another condition, and guide you toward the right diagnosis and treatment options.
The ADHD pathway: From first concerns to diagnosis
The journey to an ADHD diagnosis often starts with recognising that something isn’t quite adding up, whether it’s ongoing struggles with focus, organisation, or managing emotions.
The first step is usually a visit to your General Practitioner (GP), who can conduct an initial screening and discuss your mental health concerns. If ADHD is suspected, your GP may provide a referral to a psychologist or psychiatrist for further assessment.
A comprehensive diagnostic assessment may involve multiple appointments with a psychologist or psychiatrist. During these sessions, the clinician will gather information about your developmental history, childhood symptoms, and current challenges.
They may also ask for input from family members or request school reports to build a detailed understanding of your experiences over time.
The diagnostic process is thorough. It looks at your mental health history, behaviour patterns, relationships, and daily functioning to support an accurate diagnosis. This step-by-step approach helps ensure that any further assessment or support is tailored to your unique needs.
What does an ADHD assessment involve?
Getting diagnosed with ADHD in Australia generally involves:
Initial chat with your GP
Referral to a psychologist or psychiatrist
A comprehensive assessment involving clinical interviews, questionnaires, and sometimes input from family or teachers, especially for children
A formal diagnosis, if appropriate
The diagnosis process typically includes gathering a detailed history, assessing symptoms, and evaluating how those symptoms affect everyday life.
At Reimagine, we often say: ADHD is more than a checklist. It’s about understanding the whole person—their history, strengths, challenges, and patterns. A good assessment gives you clarity, not just a label.
Who can diagnose ADHD?
In Australia, ADHD can be diagnosed by:
Psychiatrists, who are medical doctors specialising in mental health
Clinical or registered psychologists, who are trained in assessment and diagnosis
Here’s the key difference:
Psychiatrists can diagnose ADHD and prescribe medication.
Psychologists can diagnose ADHD, but they can’t prescribe medication.
If medication is being considered, you’ll usually need to see a psychiatrist after the psychologist’s assessment.
So… how much does it actually cost?
Let’s break it down by provider type.
1. Psychiatrist ADHD Assessment
Initial consultation: $400 – $900
This first in-depth session usually lasts 45–90 minutes. During this appointment, the psychiatrist assesses symptoms, developmental history, and any co-occurring conditions.
Follow-up appointments: $200 – $500
A follow-up appointment may be needed to complete the assessment, review previous findings, or conduct additional evaluations.
Some Medicare rebates may be available, usually around $120 for initial consultations if referred by a GP.
Out-of-pocket cost: Typically $600 – $1,200 for a full diagnosis and treatment plan.
Psychiatrists often have long waitlists, especially for child assessments. Expect a 3–6 month wait in many areas.
2. Psychologist ADHD Assessment
Initial session: $220 – $280
Full assessment package: $600 – $1,500 total, usually over 1–3 sessions
Medicare rebate with a Mental Health Care Plan: around $89 per session, up to 10 sessions per year
Private health: May rebate a portion, depending on your policy
At Reimagine, we offer assessment and ongoing therapy, which means you don’t just get a report—you get a plan, support, and someone in your corner.
3. Paediatricians
Paediatricians are often involved in early diagnosis for younger children.
Appointments may cost $300 – $600 per consultation, with some Medicare rebate available.
What about online ADHD assessments?
There are now many online options for ADHD screening and diagnosis. Some are helpful as a starting point, such as questionnaires and symptom checklists. But a formal diagnosis requires a clinical interview with a qualified psychologist or psychiatrist.
If you’re considering online assessments:
Check the clinician’s qualifications and AHPRA registration
Make sure the service includes follow-up support, not just a PDF report
Look for services that support clients after the assessment, not just during the diagnosis process
Telehealth has made ADHD assessments more accessible, especially in rural or remote areas. At Reimagine, we offer both in-person and online assessments depending on your needs.
Access and equity: navigating barriers to ADHD diagnosis
Accessing an ADHD diagnosis in Australia can be challenging, especially when it comes to cost, wait times, and availability of services.
ADHD assessments for adults and children can be expensive, with out-of-pocket costs remaining high even after Medicare rebates. While a Mental Health Care Plan can help reduce some expenses, many people still face significant financial barriers.
Wait times for appointments with psychiatrists and psychologists can also be lengthy, especially in major cities where demand is high. For those living in rural or remote areas, limited access to specialist services can make the process even more difficult.
These barriers can delay diagnosis and treatment, leaving many people with unmet needs. Exploring telehealth options and speaking with your GP about available pathways may help you understand what support is accessible for you.
What a diagnosis actually gives you
We’ve seen first-hand how powerful it is when a client hears the words: “You’re not lazy. Your brain just works differently.”
A diagnosis can:
Offer language and clarity
Help you access support at school, university, or work
Inform therapy and coaching plans
Open up the option of medication, if desired
Reduce shame and increase self-understanding
A thorough assessment can also help distinguish ADHD from other conditions that may have similar symptoms. Clinicians may also screen for autism or other neurodevelopmental differences during the assessment process to support an accurate diagnosis and tailored support.
But diagnosis is not the end goal.
ADHD medication and treatment: what comes next?
Receiving an ADHD diagnosis is a significant milestone, but it’s just the beginning of your journey toward managing ADHD and improving daily life.
The next step is to work with your healthcare team to develop a personalised treatment plan. This may include considering ADHD medication, which can help reduce symptoms and improve focus. Finding the right medication and dosage is a process that requires ongoing support from your doctor or psychiatrist.
Therapy, such as cognitive-behavioural therapy (CBT), can also be an important part of treatment. It can help you build practical strategies for managing ADHD symptoms and addressing any co-occurring mental health concerns, such as anxiety.
Lifestyle changes—such as regular exercise, healthy eating, sleep routines, and stress management—can also support daily functioning.
A mental health care plan can help you access the right support, whether that’s therapy, medication, or both. Ongoing support and regular follow-up appointments are important for adjusting your treatment plan as your needs change.
Diagnosis is only the beginning
This is where we get real: a diagnosis won’t magically fix everything.
It’s a starting point. The real change happens through therapy, daily strategies, environmental support, and learning how to work with your brain, not against it.
At Reimagine, we’re big believers in the long game:
Therapy to build emotional regulation and executive function
ADHD-friendly planning tools and routines
Parent coaching and family sessions
Guidance on school or workplace adjustments
Shared-care arrangements between psychiatrists and GPs for prescribing ADHD medication are increasingly common in Australia.
We don’t just assess and say goodbye. We walk with you—messy days, wins, setbacks and all.
Real talk: why cost shouldn’t stop you
We know it’s expensive. And in a cost-of-living crisis, it might feel impossible. But there are ways to make it more accessible:
Use a Mental Health Care Plan: Get rebates on therapy with a psychologist
Check private health: Some extras policies cover assessments
Consider telehealth options: This can reduce travel and improve access
Start with one session: You don’t have to do it all at once
Talk to your GP: Ask about available referral pathways and public options
If you’re unsure where to begin, book a 15-minute intro call with our team. We’ll point you in the right direction, even if that’s not us.
