Orygen Youth Health (OYH) provides specialist mental health services for young people aged 15 to 24 who reside in the western and northern regions of Melbourne. In 2016, approximately 200,000 young people aged 15-24 years lived in the OYH catchment area of North West Melbourne.

OYH’s focus is on providing early intervention to young people with severe and complex mental illness. It provides services to approximately 1000 young people each year (from the more than 4,000 young people who are referred). OYH also works alongside Orygen, the National Centre of Excellence in Youth Mental Health which operates four primary mental health care headspace services in the catchment area.
