About Heidi

Heidi has been working as a clinical psychologist since 1997. She enjoys working with adults and older adolescents (17+) and has an interest in helping people who experience:

  • Obsessive Compulsive Disorder (OCD)
  • Attention Deficit Hyperactivity Disorder (ADHD))
  • Social Anxiety Disorder
  • Post Traumatic Stress Disorder (PTSD)
  • Health Anxiety
  • Autism
  • Sleep difficulties
  • Depression
  • Bipolar Disorder
  • Adjustment Disorder
  • Body Dysmorphic Disorder
  • Life transitions

Heidi's primary therapy styles are:

  • Cognitive Behaviour Therapy (CBT)
  • Eye Movement Desensitisation and Reprocessing (EMDR)

Her practice is also informed by:

  • Mindfulness Based Cognitive Therapy
  • Interpersonal Psychotherapy
  • Acceptance and Commitment Therapy (ACT)
  • Schema Therapy

Heidi believes that good mental health care involves a genuine desire to imagine walking in someone else’s shoes in order to see the world from their perspective. It also relies upon compassion and warmth, a knowledge of the scientific literature, practical experience, and mutual respect between the two parties.A good dose of shared humour also helps to normalise difficult life experiences.

Heidi completed her Honours Degree in Psychology at the University of New South Wales in 1992 after an interesting side journey in music industry management. She achieved her registration as a psychologist at St Vincent's Hospital's Clinical Research Unit for Anxiety and Depression (CRUfAD) where she co-authored a World Health Organisation textbook called “The Management of Mental Disorders”. She later studied for her Masters Degree in Clinical Psychology at the University of Sydney which she completed with Merit in 1996.

Heidi has worked at Peakhurst / Hurstville Community Mental Health Centres seeing people with severe psychiatric disorders before moving solely into private practice in 1998. She established Mindcare Centre in 2004 with her husband and psychiatrist Dr Hugh Morgan where she has offered a stable and long term service to people as they move through their lifespan.

Heidi was involved in the foundation of the Australian Clinical Psychology Association (ACPA) and is currently a member of the Australian ADHD Professionals Association (AADPA). She has previously been on the executive committee of the NSW Branch of the Australian Psychological Society’s College of Clinical Psychologists.

Heidi (and Hugh) relocated from Sydney to the Northern Rivers in 2021 to enjoy a slice of nature, gardening, craft, good food, new colleagues, and friends old and new. Her adult children have flown the coop making it a good time for a tree and sea change.

An initial and follow-up appointment with Heidi Sumich is 50-60 minutes in length and costs $268 which is below the $300 fee recommended by the Australian Psychological Society. Unfortunately Heidi does not Bulk Bill so there will be an out of pocket cost for each appointment.

If you have a valid Medicare referral from a GP (via a Mental Health Care Plan), or a standard referral letter from a psychiatrist or paediatrician, the Medicare rebate is $137.05 for up to 10 sessions per year. Your out of pocket cost for each appointment is $130.95.  In the absence of a valid referral, there is no Medicare rebate.

The initial appointment/s include a detailed history of your current difficulties, a discussion of how they fit into your life story, along with a comprehensive plan to address your concerns.  Based on good practice (and Medicare legislation), a brief letter will be sent back to your referring doctor at various points in time, with a copy for you to keep.  The aim is to provide high quality care and transparent communication, while also respecting your need for confidentiality.

The safety net - how to budget for your health care:

The Medicare Safety Net system is designed to help make it more affordable for people to receive private health care if they have multiple health issues and need a lot of care. Each year, Medicare automatically keeps a tally of your Medicare-claimable services and counts your out of pocket costs (gap fees) towards the Medicare Extended Safety Net. 

Once your out of pocket costs each year (across all specialists, GPs and psychologists) reach a certain threshold amount, Medicare will pay back the usual rebate listed above PLUS 80% of the remaining gap fee for the rest of the year. The threshold for individuals and families is $2544.30 per year of out of pocket costs, or $811.80 per year for Concession Card Holders and Family Tax Benefit Part A). Gap fees for inpatient treatment do not count towards the Safety Net. This means the Medicare rebate for an appointment would increase to around $241.81 once you hit the Medicare Safety Net.

You need to register with Medicare to have your family members counted as part of the same safety net threshold..
