If you have a diagnosed or undiagnosed mental health problem, such as depression or anxiety, you can visit your GP for help. They are able to conduct a Mental Health Care Assessment. Your GP will ask you several personal questions to determine whether you require the services of a Psychologist or Social Worker. This means that if you meet the Medicare eligibility criteria, then you can access this service through a written referral from your GP. This referral is called a Mental Health Care Plan.
