It has been more than 30 years since the first HIV diagnosis in Australia. From the early days, monitoring of HIV has provided vital information to inform Australia’s public health response and has underpinned many successful prevention strategies. HIV surveillance helps us to know what is working well and where we need to do better.
The most recent data shows us that the number of newly diagnosed cases of HIV in Australia has declined by 7% over the past five years, with 963 diagnoses in 2017. Male-to-male sex continues to be the major HIV risk exposure in Australia, accounting for 63% of diagnoses in 2017, followed by heterosexual sex (25%).
In 2017, the reductions were greatest among gay and bisexual men, with a 15% reduction in the past year alone. However, there was a 10% increase between 2013 and 2017 in diagnoses attributable heterosexual sex, with a 14% increase between 2016 and 2017. Among the Aboriginal and Torres Strait Islander population, HIV diagnoses increased by 41% between 2013 and 2016, compared with a 12% decline in Australian-born non-Indigenous people, and in 2017 remain 1.6 times as high as the Australian-born non-Indigenous population.
There were an estimated 27,545 people living with HIV in Australia in 2017. Of those, an estimated 24,646 (89%) were diagnosed, of which 23,414 (95%) were retained in care. 21,560 (87%) of those in care were receiving antiretroviral therapy, and 20,412 had suppressed viral load. This means that in 2017 Australia met the 2020 UNAIDS global targets, with an estimated 74% of people living with HIV in Australia with a suppressed or undetectable viral load (which just exceeds the UNAIDS target of 73%).
HIV rates among people who inject drugs and female sex workers remain very low.
