Australia’s notifiable diseases status, 2009, is an annual surveillance report of nationally notifiable communicable diseases. Communicable disease surveillance in Australia operates at the national, jurisdictional and local levels. Primary responsibility for public health action lies with the state and territory health departments. The role of communicable disease surveillance at a national level includes:

  • identifying national trends;
  • guidance for policy development and resource allocation at a national level;
  • monitoring the need for and impact of national disease control programs;
  • coordination of response to national or multi-jurisdictional outbreaks;
  • description of the epidemiology of rare diseases that occur infrequently at state and territory levels;
  • meeting various international reporting requirements, such as providing disease statistics to the World Health Organization (WHO); and
  • support for quarantine activities, which are the responsibility of the national government.
