Today, Rachael advocates for systems change through advisory groups, co-design projects, public speaking engagements, and policy discussions, bringing lived experience expertise into spaces where decisions are made about the lives of people and communities. She is passionate about ensuring lived and living experience is recognised as a form of expertise alongside research, clinical knowledge, and policy evidence.
Rachael has spoken at Parliament House in Canberra on the importance of lived experience leadership in systems reform and has contributed to national conversations on mental health, justice, stigma, and social inclusion. Her work focuses on the gaps between systems and the people they are designed to support, particularly where alcohol and other drug issues intersect with trauma, housing instability, family violence, and social disadvantage.
Outside of her advocacy work, Rachael enjoys writing, storytelling, spending time with her two children, and spoiling her very loved Maltese-Shih Tzu.
