The PrEPARE Project investigates the attitudes of gay, bisexual and queer men and non-binary (GBQ+) people to biomedical HIV and STI prevention, particularly pre-exposure prophylaxis (PrEP) and treatment as prevention. National online surveys have been conducted every two years since 2011. The most recent round, conducted in 2025, suggests that Australia’s PrEP program has entered a more mature phase. PrEP awareness is now near universal, around seven in ten participants have used PrEP at some point, and use has become increasingly dynamic as people move in and out of PrEP according to changing need. Alongside this, we have observed strong interest in long-acting options such as injectable PrEP, growing engagement with biomedical approaches to STI prevention including doxy-PEP, and continued increases in familiarity with and belief in the accuracy of the Undetectable = Untransmittable (U=U) message. Together, these findings point to an increasingly diverse, choice-driven HIV and STI prevention landscape, and underscore the importance of flexible, person-centred policies and programs that support how GBQ+ people engage with sexual health across different contexts and life stages.
