What does a Psychologist do?

Practicing psychologists have the professional training and clinical skills to help people learn to cope more effectively with life issues and mental health problems

Psychologists can undertake advanced training in a specific area of psychology. Under the Australian Health Practitioners Regulation Authority (AHPRA) Psychologists can apply to be endorsed in a specific area and use a different title such as Clinical Psychologist, Counselling Psychologist and Educational and Developmental Psychologist.

Is a referral required?
A referral is not required to make an appointment with a psychologist. However should you be eligible and wish to claim a rebate from Medicare, a referral letter and GP mental health care plan from your general practitioner must be provided.
Can I get a rebate?

With a referral from your GP and the completion of a mental health care plan you are bale to access a rebate for Psychology Services. Please take note of the following important points regarding mental health care plans:

  • You must have seen your GP (or psychiatrist or paediatrician) get a mental health care plan (MHCP)
  • You must have a diagnosable mental health concern, unfortunately other problems (e.g. couple counselling) are not covered by Medicare
  • You can access up to 20 sessions in a calendar year;
  • Typically these 20 sessions are broken into 6 sessions followed by a re-referral from your GP for  4 sessions and then a second referral for the remaining 10 sessions
  • There is often a gap to pay above the Medicare rebate, the sessions are not free
  • Rebates are $129.55 for Clinical Psychology and $88.25 for Psychology per session
  • You may require more than 20 sessions to overcome your particular difficulty
  • On the first of January each year you are eligible for a further 20 sessions with a current referral from your doctor (and assuming you still meet the criteria for a MHCP)
