You are not required to have a referral from your GP to see a Clinical Psychologist. However, a Medicare rebate is available for sessions when you have obtained a referral from your GP. 

This is a simple process, however GPs prefer you to schedule a double appointment to better understand your concerns and complete a Mental Health Care Plan. Remember to bring your referral and Mental Health Care Plan to your first session at Birch Psychology in order to claim the Medicare rebate.
