This paper examines how antiretroviral therapy (ART) use and fears towards the onward transmission of HIV have changed among people living with HIV (PLHIV) in Australia between 1997 and 2018. Participants were recruited as part of the HIV Futures study, a large cross-sectional survey of PLHIV in Australia, in 1997, 2003, 2012 and 2018 (total n = 3889). ART use, viral load detectability, and fear of onward HIV transmission were compared between years. Predictors of onward transmission fear were assessed among the 2018 subsample. While ART use within our sample decreased between 1997 and 2003, it subsequently increased to 97% in 2018. Self-reported viral load undetectability steadily increased over time, up to 88% in 2018. Notably, fewer PLHIV reported being fearful of transmitting HIV in 2018 compared to all other years. Being unfamiliar with the undetectable = untransmissible health movement, and having a detectable or uncertain viral load at last test, were significant predictors of being fearful of onward HIV transmission. Beyond the immediate medical considerations of HIV treatment, these results suggest that the undetectable = untransmissible movement may play a critical role in attenuating burdens experienced by PLHIV in Australia and that such messaging, in tandem with early and consistent ART use, should remain a salient feature of heath messaging among this population.
