Matt Berriman

Chair – Mr Matt Berriman
Board Appointed Director

Matt was appointed as the Chair of Mental Health Australia on 8 December 2021. 
He began his career as a professional Australian Cricket representative and spent five years at the Victorian Institute of Sport as a coach and player, until injury forced his retirement – turning his attention to business and applying those attributes to the commercial landscape.
Matt has over 15 years’ experience in start-up businesses as a founder, executive and investor and has advised some of Australia’s largest corporate organisations, including NewsCorp and Commonwealth Bank.
Matt also has sector and lived experience, including advising Beyond Blue through its 2020 transformation and strategic reset, after announcing a bipolar disorder diagnosis in 2018. Matt looks forward to leading Mental Health Australia into a new era, working with a united sector committed to creating the best mental health system in the world.

Elected Director

Sharon is particularly passionate about addressing stigma and coercion in care (having lost close kin whilst they were receiving inpatient treatment) and improving the person’s and their family’s experiences of seeking and receiving support from services.

Sharon is also a Professor at Flinders University and has undertaken a broad range of mental health research for the past 20 years. Prior to this role, Sharon worked in mental health, aged care and disability services. Sharon brings diverse skills and experience to the MHA Board, underpinned by significant lived experience.
