Supply Nation was patterned after the National Minority Supplier Development Council (NMSDC) in the United States and maintains strong ties with them and the other members of the Global Supplier Diversity Alliance (GSDA) around the world.

Supply Nation is the Australian member of the GSDA, a global organisation which brings together supplier diversity organisations from Canada, China, UK and South Africa. GSDA shares knowledge; creates opportunities for minority-owned businesses to grow and expand globally; provides corporations around the world with access to and support from networks that effectively champion minority businesses; and encourages other countries to establish similar initiatives.
