Australian Influenza Surveillance Report

The Australian Influenza Surveillance Report and Activity Updates are compiled from a number of data sources, which are used to monitor influenza activity and severity in the community. These data sources include laboratory-confirmed notifications to NNDSS; influenza associated hospitalisations; sentinel influenza-like illness (ILI) reporting from general practitioners and emergency departments; ILI-related call centre calls and community level surveys; and sentinel laboratory testing results.

The Australian Influenza Surveillance Report is published on a fortnightly basis during the influenza season, typically between May and October. Influenza activity updates will be published outside of the seasonal period, with updates also provided during the season. A more in-depth end-of-season report is also published in Communicable Diseases Intelligence journal.

Australian Influenza Surveillance Report No 03 - 25 June to 08 July 2016


  • Influenza activity is variable across Australia; increasing in some regions, while low and stable in others.
  • Respiratory viruses other than influenza are more commonly causing influenza-like illness (ILI) in the community, with respiratory syncytial virus (RSV) and rhinovirus most commonly the cause of ILI presentations to sentinel general practitioners and various non-influenza viruses being detected by sentinel laboratories.
  • Nationally, influenza A(H1N1)pdm09 has been the predominant influenza virus circulating so far this year. However in the last fortnight influenza A(H1N1)pdm09 and influenza A(H3N2) circulated at similar levels nationally, noting jurisdictional variation.
  • To date, the seasonal influenza vaccines appear to be a good match for circulating virus strains.
