Few people know pain like Rosie Batty. In 2014, her life was turned upside down when her former partner, Greg Anderson, murdered her 11-year-old son Luke following a cricket match.
Since then, she has become an outspoken and dynamic campaigner against family violence, calling for both systemic and attitudinal change in Australia – where one woman a week will be killed by domestic violence and one in four children will experience it at home. This advocacy led to her being named Australian of the Year in 2015.
