Despite widely varying degrees of experience and training in mental health across the youth sector, those who work with young people are often the first to be told about a mental health problem, or they may be the first person to detect it. Some workers are comfortable with this but many feel that they would benefit from increased training opportunities and resources to support them in their practice. With a growing focus on improving state and national responses to youth mental health concerns, YACSA contends that now is the time to ensure that those who work with young people in a nonclinical setting, who are so often among the primary supports in young people’s lives, are fully acknowledged and supported in their work. We also seek to illuminate the issues that both workers and young people have recognised in their interactions with the mental health system – the gaps in service that they have identified, as well as the concerns that each have raised about the impact of age-based service eligibility on young people. YACSA then makes a number of recommendations, developed from the project’s findings, which reflect what workers and young people are saying needs to be done to improve mental health responses for young people.
