For students like those sitting in Australian classrooms right now, the numbers are staggering and sobering. Nearly three-quarters of Australian adolescents experience clinically significant symptoms of anxiety or depression, according to recent research. More than four million teens face projected encounters with mental illness by age 20 unless immediate action tackles the drivers of poor mental health.
The data tells a story of urgency. In 2024, 27.4 per cent of primary school students and 35.9 per cent of secondary school students reported high levels of anxiety, depression, or both. Beyond those with severe symptoms, between 40 and 50 per cent of students across all ages and genders reported high disengagement and falling levels of hope. The pattern is consistent: more young Australians are struggling than ever before.
What the research actually shows, beyond the alarming headlines, is that this crisis is predictable and preventable. The Burnet Institute, a leading Melbourne-based health research organisation, has modelled the impact of investing in prevention. If Australia dedicates between $50 million and $1 billion annually to prevention programs, modelling shows the nation could prevent up to 787,000 young Australians from experiencing anxiety and depression by 2050 and deliver up to $74 billion in societal economic benefits.
The most cost-effective interventions are school-based. According to Burnet's research, schools should prioritise bullying prevention programs, racism education, and social-emotional learning initiatives that build resilience from early childhood. The evidence is clear on this point: young people who experience racism are three times more likely to develop mental illness, and exposure to abuse, neglect, or domestic violence raises the risk of mental disorders by more than three times.
Real-world results prove prevention works. Monash University's evaluation of the Resilience Project, a whole-school program teaching gratitude, empathy, emotional literacy and mindfulness, found compelling outcomes. Students at schools in their sixth year of implementing the program had significantly better mental health outcomes across all measures. More specifically, they demonstrated 34 per cent lower odds of anxiety and 47 per cent lower odds of depression compared to control groups. The program now operates across 1150 primary and secondary schools nationally, with notable uptake in under-resourced areas including high-disadvantage and remote schools.
Policy responses are underway. Victoria is deploying mental health and wellbeing leaders (specialised teachers trained in mental health literacy) to every government and low-fee non-government primary school by the end of 2026. These leaders, trained and supported by the University of Melbourne, will embed evidence-based interventions and build teaching staff capacity to identify and support struggling students.
The challenge ahead is substantial. Parents deserve to know that while the data is confronting, the solutions exist. Schools can prevent this mental health catastrophe if given the right support, evidence-based programs, and dedicated staff. The investment case is clear: acting now through prevention in schools is far cheaper, and far more effective, than managing crisis and illness later.
