At what age should a child see a psychiatrist vs a paediatrician for ADHD?

For straightforward ADHD in children aged 6-12, a paediatrician is typically the first stop. Psychiatrists are added for complex ADHD, when medication beyond stimulants is needed, or when there are multiple conditions (e.g., ADHD plus severe anxiety or mood disorders). Most private paediatricians see children 0-16 years.

What is the difference between a child psychiatrist and a paediatrician for mental health?

Paediatricians are medical doctors specializing in child health and development. They diagnose ADHD and autism, rule out medical mimics, and prescribe stimulants and basic SSRIs. Child psychiatrists are specialist doctors for complex mental illness. They treat severe anxiety, depression, OCD, bipolar disorder, psychosis, and manage multi-medication plans. Psychiatrists typically have 11-14 years of training compared to paediatricians.

What age does a child psychiatrist see up to in Australia?

Child and adolescent psychiatrists formally see patients up to 17 years, but many now follow patients to 21-24 years to ensure smooth transition to adult services. Individual clinicians set their own age cut-offs. Some stop at 14, others continue to 21. Always check when booking.

When should I see a psychologist instead of a psychiatrist for my child?

See a psychologist first for milder emotional or learning issues, school refusal driven by anxiety, mild-to-moderate depression, or social skills work. Psychologists provide CBT therapy, behaviour programs, and cognitive testing. They cannot prescribe medication - you need a psychiatrist or paediatrician for that. Many families use both: psychiatrist for diagnosis and medication, psychologist for ongoing therapy.

How do I access public child mental health services (CAMHS) in Australia?

CAMHS (Child and Adolescent Mental Health Services) is available in all Australian states. They typically have two streams: 0-11 years and 12-17 years. They accept high-severity cases without cost but require a GP referral and have eligibility criteria. Start with your GP who can triage urgency and make the referral. Wait times can be long, so consider private options or Headspace (free, ages 12-25) while waiting.

What is the typical wait time for a child psychiatrist in Australia?

Private child psychiatrist wait times are typically 1-12 months depending on location and demand. Public CAMHS can have wait times exceeding 12 months for non-urgent cases. Tips: Ask for cancellation lists, consider telehealth psychiatrists (no geographic limit), and use Headspace or psychologist support while waiting.

Should my child see a psychologist or psychiatrist for autism assessment?

For autism diagnosis, developmental paediatricians typically coordinate the assessment for younger children (under 12). Psychologists can conduct diagnostic testing using ADOS-2 and cognitive assessments. Psychiatrists are usually involved when there is severe anxiety, aggression, or complex co-occurring conditions. For NDIS applications, autism diagnosis from psychologists or paediatricians is generally accepted.

Child Mental Health Pathways in Australia

Q: Can a GP diagnose and prescribe medication for ADHD in Australia?

Currently, GPs generally cannot initiate ADHD medication without specialist involvement. However, from 2026, specially trained GPs in NSW will be able to diagnose and prescribe for straightforward ADHD across all ages. Similar reforms may follow in other states. Complex or unclear cases will still require referral to paediatricians or psychiatrists.
