St. George Family Support Services Inc. was established in 1987 in response to the needs of families and children. The needs were identified by a sub-committee for St. George Children's Interagency who prepared a submission to the then NSW Department of Family and Community Services.

SGFSS was initially located at the rear of Rockdale City Council premises in Bryant Street Rockdale and shared premises with Rockdale Early Childhood Health Centre. The name, Backstop , emerged as a result of its location. SGFSS is located in its own premises in Jubilee Avenue, Carlton.

In 1996, as a result of a collaborative partnership between SGFSS and Sutherland Shire Family Support Services, the Southern Sydney Domestic Violence Court Support Scheme was established. SGFSS continues to train its Family Workers and Youth Worker and participates in a roster to provide this service.

Since 2008 the service has been officially known as St George Family Support Services Inc., no longer including the name backstop in its title.
