description: Phase-based approaches are a recommended treatment option for individuals with complex trauma histories; however, this is based on a limited body of empirical evidence. Phase-based approaches often involve two stages of treatment, with one focusing on safety and stabilisation and phase two on trauma memory processing. Historically, the Australian Better Access Scheme offered a government rebate for up to 10 group and 10 individual psychological sessions annually. In response to the coronavirus pandemic, the number of rebated individual sessions has been increased to 20 through June 2022. Combining individual and group session rebates, phase-based approaches that include both treatment modalities represent a feasible and accessible treatment option for complex trauma. Delivering phase one in a group milieu and providing individual treatment during phase two may be cost effective and optimise outcomes by leveraging the benefits of group and individual treatment for complex trauma. This article aims to provide an overview of the psychological impact of complex trauma, to highlight barriers to seeking mental healthcare, and to critically evaluate phase-based approaches for treating complex trauma. We highlight gaps in the research, followed by a discussion regarding the benefits and limitations of using this approach in the Australian mental health care system. <b>Key points</b> <b>What is already known about this topic:</b>(1) Individuals with complex trauma face barriers when seeking psychological treatment in Australia, including the affordability of specialised mental health care.(2) The number of Medicare-rebated sessions provided by the Better Access Scheme to treat mental health problems is at times inadequate, and clients bear the burden of cost for extra treatment.(3) Despite garnering support from trauma experts, phase-based treatments for trauma related disorders have promising but limited empirical support.
