Dr. Julio Licinio studied Australia's mental health system and found that around 45% of Australians aged 16-85 will experience a common mental health condition like depression, anxiety, or substance abuse in their lifetime. His research also found that around 64,000 people experience a psychotic illness and are in contact with public mental health services annually. Licinio estimated that around $8.5 billion is spent on mental health services in Australia each year, including private and community services, hospital-based services, and consultations with professionals.
