When to See a Psychiatrist Rather Than a GP

Most people manage antidepressant treatment with their GP alone. RANZCP guidance and Beyond Blue resources describe several situations where a psychiatrist referral adds value — complex diagnoses, treatment-resistant symptoms, medication combinations, and specialist populations. Understanding the difference helps you know when to ask.

What GPs and psychiatrists do differently

GPs are trained in general medicine and manage most straightforward mental health treatment. Psychiatrists are medical specialists with additional years of training specifically in mental health. Psychiatrists spend longer with each patient, can prescribe a broader range of medications, and have expertise in complex cases. A GP referral is required to access Medicare rebates for psychiatry.

When to consider a psychiatrist referral

Diagnosis is unclear or complex. Two or more antidepressants have not worked adequately. You need medications not usually managed by GPs (mood stabilisers, antipsychotics, certain augmentation strategies). Symptoms include psychosis, mania, or severe self-harm. Pregnancy or planning pregnancy while on antidepressants. Multiple co-occurring conditions (mental health plus physical, or multiple mental health conditions).

How the referral works

Your GP writes the referral. Wait times to see a psychiatrist can be long in Australia — from a few weeks in some cities to several months in others. Public psychiatry access (through community mental health services) may be free but requires meeting eligibility criteria. Private psychiatry has fees plus Medicare rebate. Some psychiatrists work by referral only through GPs; others accept direct referrals. For the treatment-plan context, see What Is a Mental Health Treatment Plan in Australia?.
