How to get started

Step 1 — Book a long appointment with a GP. Ask for a Mental Health Care Plan and tell them you'd like a referral for an adult ADHD and Autism assessment. The MHCP unlocks Medicare rebates on a portion of the assessment cost.

Step 2 — Choose a clinician who assesses both ADHD and Autism in adults. Many practitioners only assess one condition. The AuDHD-affirming directory on this site is filtered for dual-presentation experience.

Step 3 — Attend the assessment (usually 2–4 hours over 1–2 sessions, plus questionnaires). The clinician returns a written report and recommendations.

Costs and Medicare

Assessment packages in South Australia range from AUD $1,800–3,500. Medicare rebates cover part of the psychologist time on an MHCP — typically a few hundred dollars. Psychiatrist consults are rebated separately under different MBS items. Public-system assessments exist but waitlists are long (often 12+ months).

Wait times

Private wait times in South Australia are currently 8–28 weeks. Telehealth-only practitioners are often faster than in-person. Expect longer waits with the most experienced AuDHD clinicians.
