- There were 903 new HIV diagnoses in 2019. This represents a decline of 12 per cent over five years.
- While long term trends suggest HIV is declining in Australia, there was a slight increase in HIV numbers from 2018–2019.
- The number of new HIV diagnoses among Aboriginal and Torres Strait Islander peoples fluctuated over the last five years, but Aboriginal and Torres Strait Islander peoples continue to be diagnosed with HIV at a higher rate than Australian-born non-Indigenous Australians.

(SYDNEY, Tuesday 1 December 2020) New HIV data, released today by the Kirby Institute at UNSW Sydney for World AIDS Day, are a reminder for Australia to sustain its efforts in HIV prevention amidst the COVID-19 pandemic.
There were 903 HIV diagnoses in Australia in 2019, representing a decline of 12 per cent over the past five years.
“Among gay and bisexual men, the population with the highest burden of HIV in Australia, we see that diagnoses have declined even further – by over 20 per cent in the past five years,” says the report’s author Dr Skye McGregor from the Kirby Institute. “This indicates that our combination of prevention strategies to increase testing and treatment, and increased access to PrEP, are working.”
Testing ensures people are aware of their HIV status and can start appropriate treatment and care. Taking treatment results in viral suppression – or undetectable viral load – meaning it is impossible for someone to transmit HIV to their partners. PrEP is a medication that prevents HIV negative people from acquiring HIV.
While Australia recorded a small increase in diagnoses from 2018–2019, the single-year increase is not significant enough to represent a change in the overall downward trend in diagnoses.
“With lower numbers of HIV diagnoses in Australia now each year, we expect to see small fluctuations from year to year,” says Dr McGregor. “This can be caused by increases in specific geographical areas, increases in testing, or sometimes, by an actual increase in infections.
“When we focus on people who have been diagnosed with HIV within a year or less of acquiring HIV – also known as newly acquired cases – we see that the number of diagnoses in this category has declined by 35 per cent in the last five years. This decrease suggests that our recent efforts to prevent HIV transmission are working.”
Success on international targets
In 2019, Australia became one of only a handful of countries globally to achieve the 2020 HIV elimination targets set by UNAIDS to have 90 per cent of all people living with HIV know their HIV status, 90 per cent of all people diagnosed with HIV taking antiretroviral therapy, and 90 per cent of all people receiving antiretroviral therapy to have achieved viral suppression (meaning that their treatment is working and effectively prevents the transmission of the virus to other people).
According to the report, in 2019, 90 per cent of the 29,045 people living with HIV in Australia had been tested and diagnosed with HIV. Of those diagnosed, 91 per cent were on treatment, and of those on treatment, nearly all (97 per cent) had an undetectable viral load.
“Australia can be very proud to have achieved this global target,” says Dr McGregor. “Successful partnerships between government, healthcare, community and research sectors in Australia have meant more people are being tested for HIV, more people living with HIV are on treatment, and there has been a high uptake of prevention strategies like pre-exposure prophylaxis (PrEP).
“We now set our eyes on the 2030 targets to achieve 95-95-95 by 2030. Having already achieved one of these is great news for Australia, but there is progress to be made on other targets to ensure we remain a global leader in HIV prevention,” says Dr McGregor.
Encouraging numbers among Aboriginal and Torres Strait Islander peoples
This year’s report has shown that among Aboriginal and Torres Strait Islander peoples, the number of HIV diagnoses has fluctuated over the past five years, but diagnosis rates are still between 1.3-1.9 times higher than in Australian-born, non-Indigenous Australians, each year.
“The take home message is that Aboriginal and Torres Strait Islander peoples continue to be diagnosed more often with HIV when compared to non-Indigenous Australians. To reduce this unacceptable gap, there needs to be sustained investment in targeted, culturally appropriate, community focussed campaigns,” says Professor James Ward from the University of Queensland.
Prevention strategies driving down HIV in gay and bisexual men
Professor Andrew Grulich, who heads up the Kirby Institute’s HIV Epidemiology and Prevention Program says, “the combination of prevention strategies we have available offers the opportunity to eliminate HIV transmission in gay and bisexual men in this country. This includes maintaining good access to HIV testing and treatment services and increasing access to PrEP.”
Thanks to the combined efforts of these strategies, there continue to be declines in HIV among gay and bisexual men, with a 21 per cent reduction in diagnoses over the past five years. Among Australian-born men gay and bisexual men, the decline was 33 per cent.
PrEP became available nationally in 2018 through the Australian Government’s Pharmaceutical Benefits Scheme. Since 2018, the number of people on PrEP in Australia has quadrupled. “This means that approximately 31 per cent of eligible gay and bisexual men are taking PrEP. While this is great news, it is still well below the national target of 75 per cent. It’s important we maintain momentum on PrEP, especially in the context of the COVID-19 pandemic, to ensure all people in need can access it. It is particularly important that we design health promotion strategies and adapt health services to increase access for men born overseas,” says Professor Grulich.
Mixed outcomes for other populations
The report reveals no declines in HIV diagnoses in heterosexuals or people born overseas, with numbers remaining stable since 2015. Also, around half of these people are diagnosed late (four or more years since they likely acquired HIV), suggesting that more targeted testing campaigns are necessary among these groups.
As has been the case for many years, rates of HIV among sex workers and people who inject drugs remain exceptionally low, thanks to decades of successful prevention strategies, which need to be sustained to ensure these low rates are maintained.

“Australia has played a leading global role pushing for strong targets to end HIV transmission. This data confirms we are among a small handful of nations to meet the UNAIDS 2020 goal, with 90 per cent of those living with HIV tested and diagnosed, 91 per cent on treatment and 97 per cent achieving an undetectable viral load."
“However, we can and should be more ambitious. With renewed political and financial commitment we can achieve 95/95/95 by the middle of the decade."
“While we continue to make inroads, it’s time to double-down. COVID-19 is reminding us that infectious diseases aren’t over until transmission ends. New technologies such as PrEP and self-testing are helping, but further progress demands additional investment in the HIV community workforce.”
Scott Harlum, President of the National Association of People With HIV Australia (NAPWHA).
“People living with HIV have always been at the forefront of prevention. Historically functioning as the safe sex educators in their sexual relationships; in recent years, they have embraced treatment as prevention with gusto."
"These data are testimony to the commitment of people with HIV in Australia to maintain their own health while ensuring the safety of others.”
