Abstract
The Gay Community Periodic Surveys (GCPS) are cross-sectional surveys of gay and homosexually active men in Australia. The primary aim of the surveys is to provide data on sexual, drug use and testing practices related to the transmission of HIV and other sexually transmissible infections (STIs) among gay men. The first GCPS was conducted in Sydney in 1996, with recruitment commencing in Melbourne, Queensland (Brisbane, Gold Coast, Cairns), Adelaide, Perth, and Canberra in subsequent years. In 2014, the GCPS was conducted for the first time in Tasmania. While it had not been conducted in Tasmania prior to this, three small surveys of gay men, which used questions based on those from the GCPS, were conducted in 1997, 1998, and 2002.
