The Annual Surveillance Report has been published each year since 1997. The Annual Surveillance Report provides a comprehensive analysis of HIV, viral hepatitis and sexually transmissible infections in Australia and includes estimates of incidence and prevalence of HIV and viral hepatitis, by demographic and risk groups, patterns of treatment for HIV and viral hepatitis infection, and behavioural risk factors for HIV and hepatitis C infection. 

Figures published in each Annual Surveillance Report are also available in a downloadable slide set.
