Everything you need to know before you book an assessment
No, you do not need a referral. You can make an appointment with a psychologist without a referral from your GP or a paediatrician/psychiatrist. If you decide to do this you will need to pay the full amount for your sessions out of your own pocket.
In Australia, psychologists (and other health professionals) are not allowed to use client testimonials. This rule is to protect clients' privacy and to avoid creating unrealistic expectations about outcomes.
Instead of reviews, it can be more useful to focus on the connection with your therapist. The first session is an opportunity to get a sense of how we work together and whether the approach feels right to you.
The length of assessment sessions can vary depending on the specific assessment being completed. Typically an intake session for an assessment is between 1.5-2 hours, and a testing session is between 1.5-2 hours. Your psychologist will explain to you how long your assessment session is expected to last prior to your appointment.
You will need to make an appointment with your Paediatrician or Psychiatrist who will assess whether you are eligible for a Complex neurodevelopmental disorder and disability services plan. This plan is available if you are under 25 years of age.

To be able to claim the Medicare rebate for your session you will need to bring a copy of your referral to your first appointment with your psychologist.
Psychiatrists and psychologists both support mental health, but they have different training and roles.
Psychiatrist
A medical doctor (completed medical school)
Can diagnose mental health conditions
Can prescribe medication (e.g. antidepressants, ADHD medication)
Often focuses on medical management of symptoms
Sessions are typically shorter and less frequent
Psychologist
Trained in psychology (not a medical doctor)
Can assess and diagnose mental health and learning conditions
Provides therapy (e.g. CBT, ACT, behavioural strategies)
Completes detailed assessments (e.g. ADHD, autism, learning disorders)
Focuses on understanding patterns, skills, and long-term change
In practice
You might see a psychologist for assessment, therapy, and practical strategies
You might see a psychiatrist if medication is needed, often alongside therapy
For assessments
If you're seeking clarity around things like ADHD, autism, or learning differences, this is typically completed by a psychologist, sometimes with input from a psychiatrist if medication or more complex diagnostic input is required.
To help their child feel comfortable during a psychological assessment, parents should explain the process in simple, reassuring terms, emphasising that it’s to understand and support them better. Use child-friendly language, avoiding words like “test” and instead saying “activities” or “games.” Reassure the child that they are not in trouble and encourage curiosity by addressing any concerns they may have. If available, show pictures of the psychologist and the clinic room from the website to help the child feel familiar with the environment beforehand. Additionally, suggest that your child bring a favourite toy or keepsake that helps them feel safe and at ease.
The National Disability Insurance Scheme (NDIS) may fund developmental assessments and reports that support a formal diagnosis for neurodevelopmental conditions. Speak to your Plan Manager or Support Coordinator to find out if you are eligible.
Yes. However, you will need to check if your Private Health Insurance covers psychological assessment.
A structured process that may include interviews, questionnaires, and standardised testing to understand how you (or your child) think, learn, and function day-to-day.
If things feel harder than they should—attention, learning, emotions, behaviour, or relationships—an assessment can help clarify what’s going on.
Commonly ADHD, autism (ASD), and specific learning disorders (e.g. dyslexia), as well as broader cognitive and emotional profiles. Our Psychologists are able to take into account complex social factors and life experiences that may overlap with neurodevelopmental and learning disabilities.
An assessment is the process; a diagnosis is one possible outcome based on the results.
Typically completed over a few sessions, with a detailed report provided afterward. Time-frames can vary depending on complexity.
Children (aged 6yrs +), adolescents, and adults.
You’ll receive a detailed report and a feedback session with practical recommendations and next steps.
Not always. Sometimes the outcome is greater clarity without meeting criteria for a formal diagnosis—but still with helpful recommendations.
Assessments use evidence-based tools and clinical judgment to provide a reliable understanding of strengths and challenges.
Some components can be completed online, but certain standardised tests are best done in person.
Generally, no special preparation is needed. You may be asked to complete questionnaires beforehand.
No, the tasks you will complete assess your approach to solving different types of problems.
Yes, reports can often be used to support adjustments, accommodations, or funding applications.
That’s common. An initial discussion can help determine the most appropriate pathway.
