Post traumatic stress disorder, commonly known as PTSD, is a term many Australians and New Zealanders are familiar with. But there is another form of post traumatic stress that is less well known, despite being widely experienced: complex PTSD, sometimes referred to as C-PTSD.
Understanding the difference between PTSD and complex PTSD can help people make sense of their own experiences, seek the right support, and feel less alone in what they are going through.
FearLess is a charity that works with people living with the consequences of post traumatic stress and their families. This article is intended as a general awareness resource. It is not medical advice. If you are concerned about your mental health, please speak with a qualified healthcare professional.
What is PTSD?
PTSD is a mental health condition that can develop after a person experiences or witnesses a traumatic event. This might include a serious accident, a physical assault, a natural disaster, or the sudden death of a loved one. Symptoms include re-experiencing the event through flashbacks or nightmares, avoiding reminders of the trauma, hypervigilance, and emotional detachment.
For a more detailed overview of PTSD and its symptoms, FearLess has a dedicated page at fearless.org.au/ptsd.
What is complex PTSD?
Complex PTSD develops when a person has experienced prolonged or repeated trauma, rather than a single event. This often includes situations where the person had little control or felt unable to escape. Common examples include childhood abuse or neglect, long-term domestic violence, refugee experiences, and sustained community or institutional trauma.
Complex PTSD carries all the hallmarks of PTSD, including flashbacks, avoidance, and hypervigilance. But it also involves additional challenges that reflect the sustained nature of the trauma, including difficulty managing emotions, deep feelings of shame or worthlessness, a negative sense of self, and difficulty forming or maintaining trusting relationships.
People living with complex PTSD may not realise their experiences have a name. They may have spent years wondering why they feel the way they do. Having language for an experience does not define a person, but it can be the beginning of finding the right support.
How are they different?
The key distinction is the nature and duration of the trauma.
PTSD most commonly follows a single identifiable traumatic event. Complex PTSD develops from experiences that were ongoing, cumulative, and often occurred during childhood or within close relationships, where trust and safety were repeatedly violated.
Because of this, complex PTSD often involves a deeper disruption to a person’s sense of identity and their ability to feel safe with other people. The impact can reach into every area of life, including work, parenting, friendships, and physical health.
It is also worth noting that complex PTSD and PTSD can coexist, and that symptoms can shift over time.
Who is affected?
Complex PTSD can affect anyone who has lived through sustained trauma. In Australia and New Zealand, this includes survivors of childhood abuse and neglect, people who have experienced long-term domestic violence, refugees and people who have been displaced, members of Indigenous communities who have experienced intergenerational trauma, and people who have worked in environments with repeated traumatic exposure, such as emergency services.
Research consistently shows that women are at higher risk of developing PTSD and complex PTSD than men, partly due to higher rates of interpersonal violence and sexual trauma.
What does recovery look like?
Recovery from complex PTSD is possible. It takes time, and it rarely looks like a straight line. There will be hard days and better days. Progress is real even when it is not obvious.
Psychological therapies that are trauma-focused are considered the main approach to treatment. A GP is a good starting point to discuss symptoms and explore what is available. For those in regional or remote areas, or who prefer flexibility, digital and telehealth options exist.
FearLess has resources on treatment approaches at fearless.org.au/healing-strategies and on PTSD treatment options in Australia at fearless.org.au/2025/11/02/ptsd-treatment-options-australia.
You are not your diagnosis
Being told or reading that what you have experienced has a name is not the end of the story. It is, for many people, the beginning of understanding. Complex PTSD is not a life sentence. It is a response to something that happened, and with the right support, things can get better.
FearLess exists because no one should have to navigate post traumatic stress alone.
