Families Australia was established in 2001 as a national, member-based, not-for-profit organisation that strives to improve the wellbeing of families and children.

Families Australia’s founding member organisations are the Australian Foster Care Association, the Association of Services Supporting Australian Families (now unincorporated), the Child and Family Welfare Association of Australia, and the Secretariat of National Aboriginal and Islander Child Care.

In 2007, Families Australia established and continues to coordinate the National Coalition on Child Safety and Wellbeing, a grouping that now comprises over 200 non-government organisations providing services to children, young people and families on the ground across Australia, as well as key advocates and researchers in the areas of child protection and wellbeing.

Between 2007 and 2015, Families Australia assisted the Alliance for Forgotten Australians in its campaign to gain greater recognition and support for Forgotten Australians, a group of around 500,000 people who, as children, were placed in institutions in Australia in the 20th century.
