The Act develops and enhances oversight of public mental health services through the establishment of an independent and accessible Mental Health Complaints Commissioner.

The Act redefines the role of the Chief Psychiatrist to focus on supporting mental health service providers to improve the quality and safety of the mental health services they provide and promoting the rights of people receiving mental health services, in particular people receiving compulsory assessment or treatment.

The Act enhances service improvement through the publication of Codes of Practice that will improve understanding of, and consistency with, the new legislation.
