The NCIG Collection consists of biological samples (mostly blood) obtained from approximately 7,000 Indigenous Australians, from around 35 communities for the purposes of scientific research between the 1960s and 1990s.  The process of collection generated extensive documentation, and the output of new research using consented parts of the collection is now generating genomic data.  Thus, today the ‘NCIG Collection’ holds three types of content: biological samples, documents and data.
