ADHD Diagnosis in Perth: How to Get Assessed in 2026
An ADHD diagnosis in Perth starts with a GP screening consultation, followed by a psychiatrist referral for formal assessment. Western Australia’s Stimulant Regulatory Scheme still requires a psychiatrist or paediatrician to confirm an ADHD diagnosis and initiate stimulant medication, although 65 GPs completed specialist ADHD training in early 2026 and can now assess, diagnose, and prescribe independently within the scheme. See how Western Australia compares with every other state in Holistica Health’s national ADHD diagnosis wait times guide.
If you suspect you or your child has ADHD, this guide explains how the diagnosis pathway works in Perth, what each step costs, how long the process takes, and where the rules changed in 2026. Holistica Health offers online ADHD assessments with a guaranteed psychiatrist review within four weeks and a fixed GP consultation fee of $350.
What Does the ADHD Diagnosis Pathway Look Like in Perth?
The ADHD diagnosis pathway in Perth follows four stages: an initial GP screening using validated questionnaires such as the DSM 5 criteria, a referral to a psychiatrist for formal clinical assessment, a confirmed diagnosis with a treatment plan, and ongoing shared care between your psychiatrist and GP for medication management and monitoring.
Most adults begin by booking a telehealth or in person consultation with a GP who has experience in ADHD. The GP reviews symptom history, screens for conditions that can mimic ADHD (anxiety, depression, sleep disorders, and thyroid dysfunction), and completes cardiovascular safety checks if stimulant therapy may be considered later.
If the GP’s clinical assessment supports a suspected ADHD presentation, the next step is a referral to a psychiatrist. In Western Australia, a psychiatrist remains the primary pathway for formal diagnosis and for initiating Schedule 8 stimulant medications such as methylphenidate (Ritalin, Concerta) and lisdexamfetamine (Vyvanse). The Australian ADHD Professionals Association (AADPA) clinical guideline recommends that a formal diagnosis include a structured clinical interview covering childhood onset, symptom persistence, and functional impairment across multiple settings.
After the psychiatrist confirms the diagnosis, the treatment plan typically includes a combination of medication, behavioural strategies, and regular follow up reviews. Many patients then return to their GP for ongoing shared care, where the GP manages prescription renewals and monitors treatment response under the psychiatrist’s guidance.
Can a GP Diagnose ADHD in Western Australia?
Yes, but only GPs who completed the WA Specialist GP ADHD Training Program. The WA Government invested $1.3 million to train 65 GPs under a six month co management model with specialist mentorship. The RACGP confirmed in mid 2025 that these GPs began operating independently within the Stimulant Regulatory Scheme in early 2026, with authorisation to assess, diagnose, and initiate stimulant treatment for patients aged 10 and older.
For GPs who have not completed this training, the role remains limited to screening, referral, and shared care continuation. Under WA’s shared care model, a GP can continue prescribing stimulant medication after a psychiatrist or paediatrician initiates treatment, provided the GP obtains approval through ScriptCheckWA and meets the requirements of the Monitored Medicines Prescribing Code.
At Holistica Health, the AHPRA registered GPs conduct thorough ADHD screening consultations that include validated questionnaires, medical history review, anxiety and sleep assessments, and cardiovascular safety checks. When the clinical picture supports a suspected ADHD presentation, the team provides a fast tracked referral to a psychiatrist with a guaranteed review within four weeks.

How Much Does an ADHD Assessment Cost in Perth?
ADHD assessment costs in Perth vary depending on the provider and the type of clinician. A GP screening consultation typically costs between $100 and $400 as a private fee, while a psychiatrist assessment for formal diagnosis ranges from approximately $800 to $1,400 before any Medicare rebate.
At Holistica Health, the initial GP ADHD assessment is a fixed $350 for both adults and children. This includes the validated screening questionnaire review, clinical assessment, mood and anxiety screening, cardiovascular safety evaluation, and a structured psychiatrist referral. Follow up GP consultations for patients already diagnosed by a psychiatrist cost $139.
Psychiatrist fees at Holistica Health are charged separately and align with standard rates across Australia. A new patient adult consultation is $1,195 (with a Medicare rebate of $455.60), and a new patient child consultation is $1,395 (with the same rebate). Review consultations are $635 for adults and $725 for children.
Several factors affect the total cost of an ADHD diagnosis in Perth. Patients referred for an ECG and urine drug screen (UDS) before the psychiatrist appointment should expect additional pathology fees. Medicare rebates apply to the psychiatrist consultation but not to the GP screening if the GP is operating under a private billing model. Patients with private health insurance should check their individual cover, as some funds reimburse part of the psychiatrist gap.
How Long Is the Wait for an ADHD Assessment in Perth?
Public psychiatrist wait times for ADHD assessment in Perth have historically ranged from 6 to 18 months. Private psychiatrists often have shorter wait lists, but availability fluctuates and fees are higher without a GP referral pathway in place.
The demand for ADHD assessment has increased significantly since 2020. The RACGP reported that adult ADHD awareness campaigns, reduced stigma around diagnosis, and growing evidence for the benefits of treatment in adults have all contributed to longer specialist queues across Australia. Perth is no exception, and regional Western Australia faces even longer delays due to fewer available specialists.
Holistica Health addresses this bottleneck with a four week guarantee for psychiatrist review after the initial GP assessment. The clinic’s ADHD assessment service coordinates the referral directly, so patients do not need to find their own specialist or manage separate bookings. The entire pathway from GP screening to psychiatrist review is completed within four weeks for most patients.
Patients in regional WA, rural communities, and remote areas benefit from the telehealth model because the GP screening, follow up reviews, and care coordination all happen via secure video consultation. The only in person requirement is the ECG and UDS, which can be completed at a local pathology centre or pharmacy.
What Happens During an Adult ADHD Assessment?
An adult ADHD assessment is a structured clinical evaluation that reviews symptoms, personal history, and functional impact across work, relationships, and daily routines.
The GP consultation at Holistica Health follows this sequence:
1. Pre screening questionnaire. Before the consultation, patients complete a validated ADHD screening questionnaire aligned with DSM 5 criteria. Parents complete a separate form for children. This questionnaire captures symptom frequency, severity, and duration across attention, hyperactivity, and impulsivity domains.
2. Telehealth GP consultation. The AHPRA registered GP reviews the questionnaire results, takes a detailed medical and developmental history, and screens for conditions that overlap with ADHD symptoms, including anxiety, depression, sleep disorders, and substance use history.
3. Cardiovascular safety screening. If stimulant medication is a potential treatment outcome, the GP assesses cardiovascular risk factors and may request an ECG and a UDS to meet WA regulatory requirements.
4. Differential diagnosis evaluation. The GP considers whether symptoms are better explained by another condition or whether ADHD co exists with other diagnoses. This step prevents misdiagnosis and ensures the psychiatrist referral includes a complete clinical picture.
5. Psychiatrist referral. If the GP’s assessment supports a suspected ADHD presentation, the team prepares a structured referral to Holistica Health’s psychiatrist. The referral includes all screening results, medical history, and safety check outcomes. Dr. Wesam AbuJalala (Dr. Wes), the Medical Director of Holistica Health [MBBS, Dip Derm, FACRRM], oversees this clinical pathway to ensure every referral meets the standard required for a timely psychiatrist review.
The psychiatrist then conducts a formal assessment, confirms or excludes the ADHD diagnosis, and develops a treatment plan that may include medication, behavioural strategies, or a combination of both.
Who Is Eligible for ADHD Medication in Western Australia?
Eligibility for ADHD stimulant medication in WA is governed by the Stimulant Regulatory Scheme, which is administered by the WA Department of Health.
A patient must receive a confirmed ADHD diagnosis from an authorised specialist (psychiatrist, paediatrician, or one of the 65 trained specialist GPs) before stimulant medication can be initiated. The prescriber must register the patient within ScriptCheckWA, the state’s real time prescription monitoring system.
Once a specialist initiates medication and the patient is stable, the ongoing prescribing can transfer to a GP under a shared care arrangement. The GP must apply for a patient specific authorisation through the WA Department of Health, and the shared care approval allows the GP to continue prescribing for up to two years before a specialist review is required.
For patients who already have a current ADHD diagnosis from a psychiatrist or paediatrician and are stable on medication, Holistica Health offers follow up consultations at $139 to manage prescription renewals and ongoing monitoring. WA monitored medicine requirements apply, and all prescribing at Holistica Health complies strictly with state regulations.
