Starting with a colourful childhood in Collingwood and Doncaster and ending in sunny Bondi, All I Know is a journey through the life of Mary Coustas, and a journey through the three deaths that changed her life forever. In a voice rich with big-hearted generosity and quick-witted humour, Mary Coustas shares with us the heartbreak she faced while entertaining audiences as the larger-than-life Effie Stephanidis, and the life lessons she hopes can save us from giving in to grief, or denying ourselves a full life because of it. Mary's story is at times heartbreaking but, ultimately, is an enriching and uplifting celebration of life.
