The Australasian Conference on Traumatic Stress (ACOTS) provides a world class forum for the sharing of knowledge about traumatic stress within the Australasian region.


The ACOTS scientific program aims to be topical and diverse, and includes keynote presentations from internationally renowned experts in both research and clinical practice; in-depth workshops; symposia; panel discussions; and a student program.


The first ACOTS was held in 1993, hosted by ASTSS. Since 2008 the conference has been a partnership between ASTSS and Phoenix Australia. To see an overview of past ACOTS programs, see our Past Events.


The Australasian Society for Traumatic Stress Studies (ASTSS) advances trauma recovery and research through providing an academic and professional forum for extending the understanding, prevention and treatment of major stress and trauma within the Australasian region.


We do this through workshops and master classes which are held every year, our strong membership base, our website and quarterly bulletin, and through our bi-annual conference.


ASTSS is a not-for-profit organisation, which has existed for over 23 years. The initial structure of ASTSS was built around a central committee and chapters, with the latter being eventually established in all Australian states and territories and New Zealand. Our first national conference was held in Adelaide in April 1993.


One landmark achievement for the ASTSS was the organisation and hosting of the 2000 World Congress in Melbourne on behalf of the International Society for Traumatic Stress Studies (ISTSS), which was attended by over 1000 delegates. We continue to develop relationships with international trauma organisations, and are affiliated with ISTSS to help inform research, policy and support for post-trauma psychological wellbeing.



About Phoenix Australia

Phoenix Australia – Centre for Posttraumatic Mental Health promotes recovery for the 15 million Australians affected by trauma.


We do this through a combination of Research and Evaluation, Policy and Service Development, and Education and Training, integrating knowledge and skills from all of these activities to develop best practice, tailored implementation. We work with individuals, organisations and the community to understand, prevent, and recover from the potential adverse effects of trauma.


Phoenix Australia is an independent, not-for-profit organisation. A world leader in posttraumatic mental health for over 20 years, our journey began working with the defence forces, developing treatment and recovery programs for soldiers returning from conflict. Today our work has a much broader focus, as we seek to improve the outcomes for all Australians affected by trauma.


We are governed by a Board of Management headed by an independent Chair, and which includes representatives of our key stakeholders, the Departments of Veterans’ Affairs and Defence, and the University of Melbourne.


Phoenix Australia developed the Australian Guidelines for the Treatment of Acute Stress Disorder and Posttraumatic Stress Disorder, first published in 2007 and revised in 2013. The Guidelines have been endorsed by the professional bodies for psychologists, psychiatrists and general practitioners, and are a source of guidance on effective treatments for PTSD in adults, teenagers and children, for mental health practitioners and people affected by trauma throughout Australia.
