Description Australia’s National Collecting Institutions (NCIs) play a key role in collecting, preserving and sharing items which are integral to Australia’s national identity, culture and achievements. The NCIs manage approximately 59 million heritage and cultural assets, with a combined estimated value of over $10.9 billion as at 30 June 2020. This audit, as a follow-on to the Auditor-General report Management of the national collections, assessed the collection management practices of two additional corporate Commonwealth NCIs with high value collections, the National Library and the National Film and Sound Archive of Australia (NFSA). Together, these two collections are worth approximately $1.6 billion. The objective of this audit was to assess whether the Library and the NFSA have implemented effective collection management practices.
