Our Story

What is Complex Trauma

Complex trauma is surprisingly common, but is often not recognised as a major contributing factor in someone’s difficulties with life.

Estimated to affect 1 in 4 Australian adults, it is substantially different from single-incident trauma such as natural disasters, motor vehicle accidents, or physical assault. That is because complex trauma (also often referred to as ‘relational trauma’ or ‘betrayal trauma’) is interpersonal, ongoing and/or repeated. It can involve being or feeling trapped; and it may sometimes also be premeditated and extreme.

Frequently, but not always, complex trauma occurs during developmentally sensitive periods of brain development; and thereby alters the structural development of neural networks and the biochemistry of neuroendocrine systems.

The long-term consequences of complex trauma include a strong and often co-occurring relationship with numerous physical health and mental health problems, as well as economic, social, and behavioural problems throughout people’s lives. However, these are not usually thought of as related to earlier abuse or neglect; and people do not ‘grow out of it’.

Links between complex trauma and heart disease, cancer, chronic pain, emphysema, diabetes, chronic lung disease, sexual health problems, sexually transmitted infections, depression, eating disorders, major dental problems, self-mutilation, learning disorders, alcoholism, drug abuse, domestic violence, teenage pregnancies, homelessness, suicide, and more are now well-established; and the cost to society is enormous.

Establishment of Complex Trauma WA

Until relatively recently, the effect of childhood trauma was either unrecognised, or conflated with Post Traumatic Stress Disorder (PTSD). However, thanks to a growing understanding of the neurobiology of trauma, the WHO International Classification of Diseases now recognise PTSD and complex trauma (sometimes also referred to as Complex-PTSD) as two distinct clinical entities that require different therapeutic approaches.

Complex Trauma is not the same as Post Traumatic Stress Disorder
Two documents that are not the same

The need for a trauma-informed organisation that knew the Western Australia context, and which is designed to meet the unique treatment needs of people with complex trauma, was formally identified by members of the multidisciplinary Perth Complex Trauma Mental Health Professionals Network (MHPN).

Complex Trauma WA started to take shape in November 2015, when a small group of clinical psychologists in private practice donned their passionate hats, and commenced work to establish a trauma-informed professional membership organisation for service providers in Western Australia. We wanted to enhance service delivery to our clients, who all presented with a history of complex trauma; and we wanted those services to take into account the context, culture, and realities of life in Western Australia.

We were pleased to learn that we were not alone in wanting a less siloed, more coordinated approach to local service delivery. Although we heard some horror stories, we also came to know more of the many skilled service providers and extraordinary trauma support services already working in Western Australia. There was no need to duplicate services or reinvent wheels – and that is still not our aim. It also became clear that practitioners in rural regions of Western Australia desperately needed ways to access peer support networks for the work they were doing.

And it also became clear that, while many people supported the idea of collaborative service delivery, everybody was low on essential resources to drive this – time, funds, and energy.

Trauma-informed treatment works, and allows those with a lived experience heal and thrive

That just inspired us more, and in August 2018, Complex Trauma WA (COTWA) registered as a Not-For-Profit Incorporated Association. We believed that trauma-informed communities which increasingly recognise the face of childhood trauma – and the cost of silence – would go some way towards reducing the incidence of childhood trauma. We also want to increase trauma-specific professional development opportunities for practitioners in Western Australia, to support more clinicians learning about best-practice approaches in the treatment of those who have survived their childhood trauma. This way, COTWA could add value in supporting people who suffered childhood trauma to heal and thrive.

Where We Are Now

COTWA was registered as a not-for-profit incorporated association in 2018, and has become a peak body for health professionals in Western Australia who work with adults, children, families, or groups of people who present with a lived experience of complex trauma.

We have established mutually beneficial strategic partnerships with angelhands Inc, and with Australia’s National Centre of Excellence for adult survivors of childhood abuse and neglect, the Blue Knot Foundation; and have been recognised as a health-promotions charity with Gift Recipient Status.

Going Forward

Person pushing a large arrow to the right

Our continued focus is community education, practitioner training and professional development opportunities, promotion of internationally recognised best-practice guidelines for service delivery, and collaborative advocacy for those with a lived experience of complex trauma.

We have established an online spatial directory of complex trauma-trained practitioners for those seeking best practice treatment, and plan to expand it to include other services which have demonstrated they operate in accordance with trauma-informed principles. It is our intention to offer COTWA-accredited courses for Western Australian businesses and service providers who would like to become recognised as trauma-aware.

Principles of trauma informed care: safety, trust, choice, empowerment, collaboration, and respect

We will continue to provide WA-based and affordable professional development opportunities for practitioners, with internationally recognised experts in the treatment of people with a history of complex trauma.

Underpinning everything we do are the principles of trauma-informed care - Safety, trust, choice, empowerment, collaboration, and respect.

Dr Kate Burton


Kate’s interest in trauma began as a postgraduate student in the UK over twenty years ago. Following completing a doctorate in complex trauma and addiction, she retrained in counselling and family therapy, and joined the mental health field in 2015. Kate has a special interest in dissociative disorders and narcissistic abuse recovery; and in 2021 founded a clinic specialising in Complex PTSD and neurodivergence.

Kate is a published academic, an international and guest speaker, and is regularly asked to provide media commentary in relation to mental health and neurodivergence. She has held a position as an invited academic providing consultancy in relation to trauma and student well being, and prior to joining COTWA, was the co-founder of a non-profit organisation focusing on education reform. Kate is a passionate advocate for raising awareness in relation to the necessity of a trauma-informed approach across all sectors. She also comes to COTWA from a position of lived experience.

Kate is the mother of two young adults, and when she’s not working, you’ll find her pottering around her home tending to her rescue animals, dancing along to music in her kitchen, or curled up with a cup of tea and a good book.

Emmett is an emerging multi-disciplinary artist with a knack for organisation, having spent the last four years in various secretarial, and administrative positions. He also works with neurodivergent children and teenagers in a mentoring and tutoring role.

Primarily working in the arts sector, Emmett is particularly passionate about the connective power of art and storytelling in processing and healing from trauma. Their arts company, ‘perhaps, a theatre company.’, seeks to create space for others (particularly the marginalised and underrepresented) to share their stories.

Emmett also has a special interest in the role complex trauma plays in the lives of queer and neurodivergent individuals. He is currently a creative honours student UWA, exploring the ways in which the ‘trauma of the closet’ can shape queer relationships.

Sonia Smuts

Advisor to the Board: Clinical Service Delivery

Sonia trained as a clinical psychologist in South Africa, and joined the mental-health community in Western Australia in 2006.

In 2014, she volunteered to convene and coordinate the Perth Complex Trauma Mental Health Professionals Network (MHPN), to offer opportunities for other clinicians to learn more about complex trauma. From these meetings, Sonia and Ana and Vivien discovered a shared passion for better service delivery for people with a lived experience of complex trauma; and also that they made a good team!

With the addition of a number of additional board members – notably those with better business skills than the average clinical psychologist – they started Complex Trauma WA (COTWA) in 2018 and Sonia served as founding chairperson for the first few years.

In 2023, post COVID realities made it apparent that COTWA needed a fresh approach – and fresh legs! – to continue its important work in the WA community, and she handed the baton to the new board. She remains dedicated to ensuring that all clinicians on COTWA’s Spatial Directory continue to meet Blue Knot Foundation’s international best-practice standards for trauma-trained service delivery.

Vivien Bainbridge

Advisor to the Board: Prevention

Vivien became involved with COTWA in its infancy, as it slowly differentiated from the Mental Health Professionals Network interested in Complex Trauma.

Initially trained and working as an academic, Vivien subsequently realised that her real interest lay with people and their extraordinary capacity to survive. As a scientist and clinician, Vivien’s growth has always included a focus on the impact of complex trauma – in particular, the ways in which different traumata at different ages affect the growing individual, their developmental trajectory, and their sense of self; and secondly, the protective factors which seem to mitigate what would often appear to be almost indescribable horrors.

Vivien is a member of the management committee for the Australian Association for Infant Mental Health (AAIMH). In addition to her clinical experience over 25 years, many more years of life experience of all sorts, a passion to understand the human condition, and an ability to walk alongside those who need a hand; Vivien is passionate about the prevention of harm to children.

Advisor to the Board: Aboriginal/Torres Strait Islander matters

Lynn has worked in the Aboriginal sector for the past 42 years, including in her role as CEO at Derby Aboriginal Health Services. She is well-known in Aboriginal communities in WA (and beyond), and also to non-Aboriginal people whose work involves Aboriginal people. She offers an invaluable perspective of life in Aboriginal communities across decades – not only as a survivor, advocate, and service provider; but also as it pertains to the influence of various political parties and associated Zeitgeist, the reconciliation movement, the impact of Australia’s advancing economy, and global and national trends in technology advancements that affect Aboriginal people in particular ways. Lynn works from a positive, strengths-based position. She is collaborative, and believes that people can only achieve great things by working together – without blame – for a common purpose. She is a good listener, forward-thinking, inclusive, and she looks for the good in people. 

Lynn is a bit of a workaholic, and she never really ‘stops’. She has recently moved back to Bunbury, but her roots run deep in the Kimberley and she still regularly visits her mother in Derby.
