The Salvation Army is a Protestant Church with a strong philanthropic mission which led it to become highly involved with child welfare in many parts of Australia.
Sending Agency was the name given to the organisation responsible for arranging the migration of children to Australia from the United Kingdom or Malta.
Support Services are groups who provide services to assist people who were in 'care' as children. Some of these organisations also provide support services to other family members (like the care leaver's children or grandchildren) who have also been affected.
