Online Autism & ADHD Assessments for Adults | Australia Wide
Autism, ADHD, or both: One assessment, One Clinician.
Self-Referral Welcome.
Assessments from $2,200, with payment plans available.
Maybe you’ve read about autism and recognised yourself, then read about ADHD and recognised yourself there too. Many adults find that the traits seem to pull in opposite directions: craving routine but needing novelty, wanting connection but feeling drained by it. It’s relatively common for autism and ADHD to occur together (know as AuDHD) and for each to mask the other.
A combined assessment looks at the whole picture rather than treating them as separate puzzles, so you get one clear and coherent answer.
What the assessment involves
The assessment is completed online by secure videoconferencing, from wherever you are in Australia. The combined assessment involves 5 appointments in total (between 60-120mins each) over a timeframe set by you. This is usually done over around 4-8 weeks. You’ll receive tailored documentation relating to the outcome within 2 weeks and a feedback session to talk through the findings.
Pricing

If you would like a formal report this can be added for an additional $600.

About Me
I’m Catherine Eliot, a neurodiversity affirming Clinical Psychologist with over 10 years experience supporting neurodivergent adults.
I am based in Perth, WA, and offer consultations and diagnostic assessments online to people over 18 years who are seeking clarity about their neurotype.
I specialise in working with high-masking, late-identified adults, and my approach is warm, unhurried and respectful, whatever the outcome of your assessment. I also have personal insight into late-identified ADHD.
Answers To Common Q’s
Do I need a GP referral? No. Adults can book directly with me.
Is an online assessment valid? Yes, online assessments are just as valid and evidence-based as in person assessments.
How long is the wait? Currently the wait time to begin an assessment with me is around 1 - 2 weeks.
Can you prescribe medication for ADHD? No, I am unable to prescribe medication. Only a Psychiatrist or medical professional can do this.
Should I book the combined assessment or just one? If you’re unsure, the combined assessment may be the better fit when you recognise yourself in both. If you would like to talk through your experiences with me prior to booking an assessment, you can book a 60 min pre-assessment consult with me here: (Book consult)
Can I pay in instalments? Yes, payment plans are available. [find out more]
Do I need a formal report? Most people find the outcome documentation is all they need. A formal report is longer and more detailed, and is mainly useful if a prescriber, university or another service has asked for one. You can request it before or after your assessment. The fee is $600 for the combined assessment.
