CHF is pleased to present this submission to the Productivity Commission’s Inquiry into the Social and Economic Benefits of Improving Mental Health. Our submission is structured around the questions in the Commission’s Issues Paper. We make some general comments on the overall scope of the inquiry and offer specific comments in ten key areas. We devote much of our commentary to the structural weaknesses in healthcare and to the major issues for our constituency: physical and mental health comorbidity and the management of multimorbidity. We consider the lived experience feedback received in response to our survey. Our chief recommendation is that all of the recommendations in the Contributing Lives, Thriving Communities report by the National Mental Health Commission be implemented.
