The Gay Community Periodic Surveys (GCPS) are repeated, cross-sectional surveys of gay men conducted in the metropolitan areas of seven Australian states and territories. They are a key part of Australia’s behavioural surveillance system for HIV, monitoring sexual practices, drug use and patterns of testing for HIV and other STIs.

Initiated in 1996, the GCPS are conducted in capital cities and other densely populated areas of Australia where gay men congregate: Adelaide, Canberra, Melbourne, Perth, Queensland (Brisbane, Cairns and the Gold Coast) and Sydney. In 2014, Tasmania was added to the network of GCPS locations. The GCPS deliberately target men who are socially and sexually involved with gay men, and recruit participants at gay community venues and events, sexual health clinics and online. 

The surveillance system relies on a longstanding collaboration between CSRH, The Kirby Institute, state health departments, and national and state community organisations. Recruitment is typically coordinated in each state/territory by a local community organisation. The results of each survey are published in an individual state or territory report, while national trends are presented in our Annual Report of Trends in Behaviour.

The GCPS team have been awarded NHMRC Partnership Project funding during 2021-26. This additional funding will allow the team to test and evaluate changes to the system, increasing recruitment and data collection from overseas-born, bisexual and heterosexual men who have sex with men (MSM). The project will use technological advancements in recruitment, survey research and interviews.
