Psychology
at Carnacoo.
Experienced care.
A deliberately small practice.
Work that reaches into life.
I work primarily with veterans and first responders navigating occupational stress, the effects of traumatic experiences, or difficulty finding their footing after demanding roles. My small Wangaratta practice also considers suitable adult and adolescent referrals.
01
A focused practice
Experience for
demanding lives.
You may be dealing with persistent stress, the aftermath of difficult experiences, disrupted relationships or a loss of direction after service or demanding work. I give priority to veterans and first responders whose difficulties now reach into everyday life.
Other adults may also be a good fit, particularly where prolonged stress, demanding roles or a significant change in life has disrupted functioning, relationships or a sense of direction. Selected adolescent referrals are considered individually, with attention to the young person’s needs, willingness to participate and appropriate family or care arrangements.
A small caseload allows the work to be purposeful: clear goals, a considered plan, active participation and regular review. Suitability depends on the person, the clinical need and what this practice can realistically provide.
Your psychologist
Mark Mathieson.
More than 25 years working across psychology, the military, organisations, sport and demanding environments.
My experience includes eight years as a regimental psychologist with the SAS and psychological work on Alone Australia, Australian Survivor and SAS Australia. I bring that experience to a small practice concerned with your life as a whole.
At Carnacoo, I use psychological assessment and treatment informed by the Human Systems Ecology framework I am developing. We will work together to understand what is happening, agree a direction and review whether the work is useful in your daily life.
02
The approach
The session is part
of the work.
I want to understand what needs to change both within you and in the conditions of your life.
Alongside psychological work, expect to examine sleep, food routines, physical activity, time outdoors, relationships, work demands and the structures of an ordinary week. Where relevant, significant changes to daily life may be part of the plan.
Some work may take place beyond the consulting room through agreed practical tasks or planned activities. The setting, purpose, accessibility, safety and funding of any activity are discussed before it is agreed.
The approach is multidisciplinary. With consent, care may involve coordination with your GP, psychiatrist, dietitian, physiotherapist, exercise physiologist or other relevant practitioners. Nutrition and physical health needs are addressed within the appropriate professional scope.
HSE provides a wider way of understanding the relationships between a person, their body, culture, place and circumstances. Psychological treatment is chosen for your assessed needs; HSE is an emerging framework, rather than a separately validated treatment.
A little more about Human Systems EcologyIn practice
How we begin
A clear process.
A shared direction.
Understand the situation
The initial assessment explores what has brought you here, how it affects daily life, relevant history and current supports. We consider the level and type of care you need, including whether this practice is a suitable setting.
Agree a practical plan
We identify meaningful goals, choose an appropriate psychological approach and agree the work between sessions. Any involvement of other practitioners, activities outside the room, fees and funding arrangements is discussed with you.
Review what is changing
We look at progress in symptoms, functioning and the parts of life that matter to you. If the work is not helping, we discuss adjustments, other care options or whether another service would be a better fit.
After an enquiry, I review fit and current capacity, clarify the referral and funding route, and explain the next step. An initial assessment may be offered where appropriate; it does not commit you to ongoing treatment.
What the work asks of you
Willingness to engage.
Room to be challenged.
Active practice
Try agreed tasks between sessions. Expect to examine familiar patterns and, where needed, make substantial lifestyle changes.
Honest review
Discuss what is helping, what is difficult and what needs adjusting. Review the plan together rather than continue by default.
Challenge is agreed, purposeful and paced to your circumstances. Plans take account of symptoms, disability, current capacity, safety and resources. You retain choice about the work you undertake. Progress varies; outcomes cannot be guaranteed.

Before you enquire
Does this way of
working fit?
Use this short guide to consider the expectations and choose a useful next step.
If you are seeking sessions centred primarily on conversation, or would prefer not to explore practical changes outside sessions, consider whether this is the approach you want. Questions and uncertainty are welcome; readiness can be discussed.
A reflection guide, not a clinical assessment or an acceptance decision. Selections remain in this page’s memory while it is open. Nothing is automatically submitted. If you prepare an enquiry, your role, funding route and optional referral-source selections appear in an email draft for you to review; your four fit answers do not. Please enter no clinical or identifying information here.
This is a planned outpatient practice. It does not provide emergency care or continuous crisis monitoring. For immediate danger call 000; for urgent care contact your GP, treating team or nearest emergency department.
Fees & funding
Know the arrangements
before you commit.
For private care, the fee, session length, any additional agreed work and likely out-of-pocket cost are provided after the initial suitability enquiry and before you book.
The routes below explain how funding commonly works. They do not confirm that a particular scheme is available at Carnacoo: practitioner eligibility, referral requirements, individual cover and current capacity are checked before any funded appointment is accepted. An HSE-informed plan does not make every activity or allied health service rebateable.
Private payment
You can make an initial enquiry directly. A GP referral is not generally required for self-funded psychology care. If considering private health cover, check your policy and the practitioner’s eligibility with your insurer.
Medicare / Better Access
Discuss eligibility with your GP and obtain a valid referral and Mental Health Treatment Plan where required. Eligible people can receive rebates for up to 10 individual and 10 group mental health sessions per calendar year. Rebates cover part of many practitioners’ fees; confirm your expected gap and the applicable service before booking.
Medicare guidanceDVA
Ask your GP about an appropriate referral and check your Veteran Card entitlements, including any relevant Non-Liability Health Care cover. Confirm the practice can accept the referral before booking. For covered services accepted under DVA arrangements, the approved DVA fee is payment in full and no gap is charged.
DVA guidanceWorkSafe / other funded care
For Victorian WorkSafe psychology, a medical referral is required before treatment, and the psychologist must be an approved provider. Discuss your claim, entitlements and any required approval with your case manager. Confirm accepted funding, fees and any gap before booking. Other insurers and employer-funded arrangements need separate confirmation.
WorkSafe guidanceGeneral funding information checked 22 October 2026. Use the official links for current rules. Group work, extended sessions and activities beyond the consulting room require their own suitability and funding checks.

For GPs & referrers

Check the match
Consider the client groups, active approach and limited weekly availability described above. Discuss the approach with the person before referring.
Confirm the pathway
Contact Mark with your professional details and the funding route to clarify. Ask for the current secure method of providing a referral; do not send identifiable clinical information or reports in an initial ordinary email.
Provide the clinical context securely
Once a secure channel is agreed, useful referral information includes the reason for referral, agreed goals, relevant history, current supports, risk and safety needs, and funding details. Adolescent referrals also need relevant consent and care arrangements.
A referral or enquiry does not reserve an appointment. Fit, capacity, clinical responsibility and funding are confirmed before treatment is arranged.
