The National Broadband Development Group (NBDG) was established in 2007 as a working group of the Online and Communications Council.

Its primary objectives are to develop national policy settings and to support cooperative arrangements and a strategic approach to stimulating sustainable industry investment in scalable next generation broadband infrastructure for the economic, social and environmental benefit of Australia.

The NBDG is chaired by the Australian Government Department of Broadband, Communications and the Digital Economy. Membership includes senior executives from the Australian Government Department of Infrastructure, Transport, Regional Development and Local Government, the Department of Health and Ageing, the Department of Education, Employment and Workplace Relations, the Australian Government Information Management Office, all state and territory governments, a representative from the Cross-Jurisdictional Chief Information Officers Committee, representatives from the communications industry, and the Australian Local Government Association.

The Department of Broadband, Communications and the Digital Economy provides secretariat support to the NBDG and its working groups. The NBDG meets at least three times a year.
