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.

Ms Marie Piu

Ms Marie Piu
Elected Director

Marie is a registered psychologist with a career spanning over three decades. She is passionate about seeing the mental health system transformed into a safe, inclusive, fair and well-funded system. One transformed from the current crisis driven structure, to one with compassion at its core. A system where recovery is recognised as occurring within a relational context and family and friends are recognised as key partners, meaningfully engaged in the governance, development and evaluation of services and entitled to respect, kindness, information and support in their own right. Her professional experience includes senior roles in management consulting, the union movement, police, transcultural, clinical and community health.
Marie has been the CEO of Tandem, the Victorian Peak body and trusted voice of family, carers, and supporters in mental health and also the auspice for the Carer Lived Experience Workforce network (CLEW) since 2016. This role is informed by her lived experience of supporting her now elderly migrant mother with a psychiatric diagnosis since childhood, and more recently other young family members in the public and private mental health systems.
Marie was proud to accept a general TheMHS Mental Health Service Award of Australia and New Zealand in 2022, in recognition of the achievement of excellence, innovation and best practice in mental health services for Tandem on behalf of the team, board, patrons and members. Marie joins the Mental Health Australia Board as a representative member of Mental Health Carers Australia, the only national advocacy group solely concerned with the well-being and promotion of the needs of families and carers in mental health.
