The Queensland Gay Community Periodic Survey is an annual cross-sectional survey of gay and homosexually active men recruited through a range of sites in Brisbane, the Gold Coast and the Sunshine Coast, and Cairns. The project was funded by Queensland Health. The Periodic Survey provides an annual snapshot of sexual and HJV-related practices among gay and homosexually active men. The major aim of the Queensland Periodic Survey is to provide data on levels of safe and unsafe sexual practice in a broad cross-sectional sample of gay and homosexually active men. To this end, men were recruited from a number of gay-community venues and sexual health clinics.
