The Migrant Resource Centre of South Australia (MRCSA) is an independent, non-government peak settlement agency responsible for the settlement and participation of migrants and refugee entrants across all of South Australia. These comprise new arrivals from a diversity of cultural and religious backgrounds arriving with their family members or joining family members already settled in South Australia.

Since its establishment in 1979, the MRCSA has worked with different waves of migrant and refugee settlement groups in order to assist them to adjust to their new homeland, to become self reliant, and to develop linkages with the broader community and with their local ethnic communities. In addition to its service delivery role and functions, the MRCSA advocates on behalf of its client groups and represents their interests to all levels of government. To that end, it actively contributes to mainstream public policy and service planning which impacts on the health and wellbeing, equitable access to services and social inclusion of Australians from culturally and linguistically diverse backgrounds.

The MRCSA receives funding from a wide range of commonwealth and state government agencies, as well as from sponsorship and donations. The Board of management is drawn from the Centre members and migrant communities. The MRCSA has a number of local Migrant Resource Centres in several metropolitan and regional locations that provide settlement and other allied services to new, and emerging communities of migrants and refugees and support community cultural diversity, development and harmony.
