Psychologist vs Psychiatrist: What's the Difference?

If you have ever been unsure about the difference between a psychologist and a psychiatrist, you are in very good company. It is one of the most common questions people ask when they start thinking about mental health support, and the answer is not always as clear as it should be. Both are qualified mental health professionals, but they differ in their training, approach, and what they can offer you.

What is a psychologist?

A psychologist is a university-trained professional who specialises in understanding human behaviour, thinking, and emotions. In Australia, becoming a registered psychologist requires a minimum of six years of university education, including supervised practical training.

Psychologists assess and diagnose mental health conditions, and use evidence-based therapies to help people work through a wide range of challenges. Common approaches include:

• Cognitive Behavioural Therapy (CBT) — identifying and changing unhelpful thought patterns and behaviours
• EMDR (Eye Movement Desensitisation and Reprocessing) — primarily used for trauma and PTSD
• Acceptance and Commitment Therapy (ACT) — building psychological flexibility and values-based action
• Schema Therapy — addressing deep-seated patterns that develop in childhood

Psychologists are registered with AHPRA (the Australian Health Practitioner Regulation Agency) and are bound by strict ethical and professional standards.

What is a psychiatrist?

A psychiatrist is a medical doctor who has completed additional specialist training in mental health. Their pathway includes a medical degree (typically five to six years), followed by at least five years of specialist psychiatric training.

Because psychiatrists are medical doctors, they can prescribe medication. This is one of the key practical differences between the two professions. Psychiatrists tend to focus on the biological and medical aspects of mental health, including managing medication.

Key differences at a glance

• Training: Psychologists complete university-based psychology training. Psychiatrists complete a medical degree plus specialist psychiatric training.
• Medication: Psychologists cannot prescribe medication. Psychiatrists can.
• Approach: Psychologists assess, diagnose and treat mental health conditions, mainly through evidence-based therapy and psychological assessment. Psychiatrists also diagnose, and can prescribe and manage medication.
• Medicare access: Both are accessible through Medicare, but the referral pathways differ.

When to see a psychologist

A psychologist is often the right choice when you are looking for therapy-focused support. This might include:

• Working through anxiety, depression, stress, or grief
• Improving relationships or communication skills
• Building strategies for managing ADHD, anger, or emotional regulation
• Completing a psychological assessment (ADHD, autism, cognitive, or learning assessments)
• Supporting a child or adolescent through a difficult time

When to see a psychiatrist

A psychiatrist may be the right choice when medication is being considered as part of your treatment plan. This might include:

• Conditions where medication is commonly recommended alongside therapy, such as severe depression or bipolar disorder
• Complex presentations where medication or a medical review may be needed
• Situations where your psychologist or GP has recommended a psychiatric review

Can you see both?

Absolutely, and many people do. A very common arrangement is to see a psychologist for regular therapy sessions and a psychiatrist for medication management. The two professionals can work collaboratively, sharing information with your consent to ensure your care is well-coordinated.

How Medicare works for each

For psychologists, you can access Medicare rebates through a GP Mental Health Treatment Plan, which covers up to 10 sessions per calendar year.

For psychiatrists, you need a GP referral to access Medicare-covered specialist appointments. Medicare covers a portion of the consultation fee, and there may be a gap depending on the psychiatrist's fees.
