We used a mixed-methods online survey to recruit 616 young Australians whose parents had separated, to understand their experiences and how to better support them throughout the separation process. Persistent themes included conflict, lack of communication and agency, mental health concerns, and feelings of confusion, frustration, loss, and grief. Some suggested it would have been useful to talk about reasons for the separation, their rights, opinions and feelings, with some indicating the separation process affected their ongoing mental health and relationships. There was a general preference for face-to-face counseling, closely followed by online counseling and online peer-to-peer support, indicating that a "one size fits all" approach is not suitable for young people. Young people should be offered services early in the separation process that can be extended in content to other issues such as new partners, school life and mental health, and continued beyond the timeframe of the separation process.
