Mission Australia is a national Christian charity that provides a range of community services throughout Australia. It has its roots in the Brisbane Town and Country Mission (1859) and Sydney City Mission (1862), but was only officially established in 1996, bringing together a number of city missions across the country. The organisation specialises in the areas of homelessness and housing, families and children, early learning, youth, employment and skills, substance abuse, disability, mental health, and strengthening communities. Sharon Callister has been CEO since March 2022.
