These data kept in the NNDSS provide a basis for developing public health policy, and identifying and responding to communicable disease outbreaks of national significance. The following list of communicable diseases to be notified nationally was endorsed by CDNA in September 2003 and by Health Ministers on 18 April 2008 as part of the National Health Security Agreement 2008.

Laboratory definitions developed by the Public Health Laboratory Network are also available for some diseases.

National Surveillance Case Definitions for the Australian National Notifiable Diseases Surveillance System


A working group of CDNA was convened in 2001 to revise and develop standard surveillance case definitions for all nationally notifiable diseases for reporting to the NNDSS. The surveillance case definitions were progressively developed through a consensus approach over a number of years. The Case Definitions Working Group currently comprises members representing all jurisdictions and the Australian Government Department of Health, the Public Health Laboratory Network, OzFoodNet, the Kirby Institute, the National Centre for Immunisation Research and Surveillance and other communicable disease experts. Laboratory case definitions previously developed by the Public Health Laboratory Network formed the basis for the surveillance case definitions, with clinical and epidemiological elements added, as appropriate.
