Australia has seen a downward trend in HIV diagnoses over the last decade, with a 33% reduction in overall cases. Despite this, the country's history with HIV/AIDS dates back to 1981, when the first case was retrospectively identified. The disease gained widespread media attention in 1983, and the Australian government launched a well-known advertising campaign in 1987 featuring the grim reaper, which was effective but also contributed to stigma. While HIV infection rates have generally declined, with increased testing and prevention strategies, certain populations remain disproportionately affected, including Aboriginal and Torres Strait Islander peoples, overseas-born gay and bisexual men, transgender women, and women in general. As of 2017, the prevalence of HIV in Australia was estimated at 0.1%, with a total of 38,172 cases diagnosed since the beginning of the epidemic.

What You'll Learn
HIV diagnoses in Australia have been declining
The prevalence of HIV infection in Australia has remained relatively low in the general population. In 2017, the estimated prevalence was 0.1%, similar to rates in New Zealand and the Philippines but lower than other countries in the region, including Thailand, Papua New Guinea, and Cambodia. The total number of HIV diagnoses in Australia since 2013 has been 5,118, with a higher rate of diagnosis among Aboriginal and Torres Strait Islander people compared to non-Indigenous Australians.
While HIV transmission among men who have sex with men has been a significant characteristic of the epidemic in Australia, diagnoses among gay and bisexual men have decreased by 43% in the last decade, demonstrating the success of comprehensive prevention approaches within this population. However, there has been a small increase in diagnoses among overseas-born gay and bisexual men, underscoring the need to ensure that prevention strategies reach all vulnerable populations.
Additionally, there has been a slight increase in HIV diagnoses among people acquiring the infection through heterosexual sex over the past decade. The majority of new HIV diagnoses continue to be among men who have sex with men, accounting for 68%-82% of newly diagnosed infections between 2013 and 2017. Nevertheless, the overall decline in HIV diagnoses in Australia is encouraging and reinforces the effectiveness of prevention and treatment strategies.

The first Australian HIV case was in 1981
HIV diagnoses in Australia have been on a downward trend over the last decade. In 2023, there were 722 new HIV diagnoses reported, a 33% decrease compared to the previous decade. Despite these recent declines, it is important to remember that the first Australian HIV case was reported in 1981.
The patient was a 72-year-old man who lived alone in an inner suburb of Sydney. He had never left Australia and had no history of blood transfusions. The man developed a prolonged illness starting in February 1981, characterised by anorexia, malaise, weight loss, and an episode of herpes zoster. He was admitted to the hospital in August and sadly passed away in September 1981. A preserved lymph node specimen later revealed the presence of HIV, making this the first documented case in Australia.
The early recognition of the AIDS pandemic by Australian government bodies and their swift response with effective disease prevention and public health programs, such as needle and syringe programs, played a crucial role in curbing the spread of HIV. As a result, Australia has maintained a relatively low rate of HIV infection compared to the rest of the world.
While the overall trend is positive, it is important to acknowledge that certain groups are more affected by HIV than others. For instance, there has been a slight increase in diagnoses among overseas-born gay and bisexual men, and efforts must be made to ensure that prevention strategies reach these populations. Additionally, while diagnoses have reduced significantly among Australian-born gay and bisexual men, they still account for the majority of new diagnoses, highlighting the continued need for targeted prevention and treatment programs.
Australia's response to the HIV/AIDS epidemic has been characterised by a high degree of collaboration between government and non-government stakeholders, contributing to the country's success in managing the spread of the virus.

HIV transmission is most common between men
According to statistics, there were 38,172 diagnosed cases of HIV infection in Australia as of 2017, with an estimated 27,545 people living with HIV in 2013. The prevalence of HIV infection was estimated to be 0.1% in 2017, which is comparable to rates in New Zealand and the Philippines.
While the prevalence of HIV in Australia is generally low, certain key populations are more vulnerable to the virus. HIV transmission is most common between men who have sex with men (MSM), with sexual transmission between men accounting for a significant proportion of new HIV infections. Between 2013 and 2017, sexual transmission between men accounted for 68% of newly diagnosed HIV infections in Australia, and this increased to 82% of new infections. The Gay Community Period Surveys found an 8% self-reported HIV prevalence among men attached to the gay community. In 2017, sexual activity between men was the most common route of HIV transmission in Australia, making up 63% of notifications, with an estimated HIV prevalence of 8.1% among gay and bisexual men in 2018. This rate of transmission among Australian-born MSM has been steadily declining, with an overall 21% decrease over the last 10 years (2007-2017). However, other populations, such as Aboriginal and Torres Strait Islander people, overseas-born MSM, transgender women, and women, continue to be increasingly affected by HIV.
The high rate of HIV transmission among men who have sex with men has been a key characteristic of Australia's HIV epidemic. This trend is also reflected in the demographics of HIV diagnoses, with the majority of diagnoses (90%) being made in males. The use of biomedical prevention strategies, such as PrEP, has increased among men, contributing to a decline in HIV diagnoses among gay and bisexual men by over 57% between 2013 and 2022. Despite this progress, sexual contact between men remains the primary mode of HIV transmission, accounting for 74% of diagnoses in 2016.
While HIV transmission between men is the most common route, it is important to note that other modes of transmission also contribute to the overall HIV landscape in Australia. Heterosexual contact accounts for a significant proportion of new HIV infections, with inconsistent condom use during casual sex reported by 49% of heterosexual individuals. Additionally, HIV notification rates among Aboriginal and Torres Strait Islander peoples are twice as high as those of non-Indigenous people. This population experiences higher rates of sexually transmissible infections, such as Chlamydia and gonorrhoea, which may contribute to the higher HIV notification rates.
In summary, while Australia has made progress in managing its HIV epidemic, with overall declining trends, HIV transmission between men remains the most common route of infection. The high prevalence among men who have sex with men continues to be a key focus area for HIV prevention and management strategies in Australia.

HIV prevention strategies are working
Australia has made significant progress in its efforts to prevent HIV transmission and support those affected by the virus. The country's comprehensive approach to HIV prevention has led to a downward trend in HIV diagnoses over the last decade, demonstrating the effectiveness of its strategies.
One key strategy has been the increased use of pre-exposure prophylaxis (PrEP), which has been crucial in reducing HIV transmission risk. PrEP is now listed on the Pharmaceutical Benefits Scheme, making it more affordable and accessible to those who need it. In 2023, Australia saw record numbers of people prescribed PrEP, which has contributed to the overall decline in HIV diagnoses.
Additionally, Australia has embraced an evidence-based approach to HIV prevention, integrating new scientific findings on biomedical HIV prevention into its strategies. This has resulted in a lower prevalence of HIV among specific populations, including gay, bisexual, and other men who have sex with men, Aboriginal and Torres Strait Islander peoples, people who inject drugs, and sex workers and their clients, compared to the rest of the world.
Peer education has also played a pivotal role in Australia's success. By employing peers or former members of specific communities as educators, Australia has effectively engaged and educated individuals in marginalised communities, including gay, bisexual, and other men who have sex with men, as well as sex workers. This approach has proven more impactful than external agency-led approaches, as peers possess an inherent understanding of cultural nuances and language within these communities.
Furthermore, Australia's national HIV strategies, such as the Eighth National HIV Strategy 2018–2022, have been pivotal to the country's success in HIV prevention and the treatment and care of people living with HIV. These strategies emphasise the shared responsibility of individuals, communities, governments, and organisations in preventing HIV infection and providing education and support.
While Australia is getting closer to eliminating HIV transmission, there are still areas that require attention. For instance, while diagnoses among gay and bisexual men have decreased overall, there has been a small increase among overseas-born men in this group. Additionally, while the number of HIV diagnoses remains low among Aboriginal and Torres Strait Islander peoples, there has not been a marked decline since the start of the HIV pandemic, highlighting the need to address barriers to healthcare access for these communities.

Aboriginal and Torres Strait Islander people are disproportionately affected
HIV diagnoses in Australia have been on a downward trend, with a 33% reduction in overall diagnoses over the last decade. Despite this, Aboriginal and Torres Strait Islander people are disproportionately affected by HIV. Between 2015 and 2019, there were 173 HIV diagnoses among this population, with a higher rate of diagnosis compared to Australian-born non-Indigenous people (3.3 per 100,000 vs 2.8 per 100,000). The exposure to HIV infection also differed, with a higher proportion of cases attributed to heterosexual contact and injecting drug use in the Aboriginal and Torres Strait Islander population.
The rate of HIV diagnosis among Aboriginal and Torres Strait Islander people increased from 4.8 per 100,000 in 2012 to 6.4 per 100,000 in 2016, while in the same period, diagnoses among Australian-born non-Indigenous people decreased by 22%. This marks a significant shift, as the rate of diagnosis for Aboriginal and Torres Strait Islander people has historically been lower than for non-Indigenous people since data collection began in 1992.
There are several factors contributing to the higher rates of HIV among Aboriginal and Torres Strait Islander communities. Firstly, they face additional barriers to accessing healthcare due to the traumatic legacy of colonisation and ongoing racism and discrimination within the health system. This results in poorer health outcomes across various socio-cultural determinants, such as education, income, unemployment, and access to health services. These factors have been identified as HIV risk factors globally.
Additionally, there has been a low uptake of biomedical HIV prevention interventions, such as treatment as prevention (TasP) and pre-exposure prophylaxis (PrEP), within the Aboriginal and Torres Strait Islander communities. The low uptake of PrEP is particularly concerning as it is a critical strategy in preventing HIV transmission.
To address this issue, Robert Monaghan, Manager of Aboriginal and Torres Strait Islander Health Research at the Kirby Institute, emphasizes the need for co-designed awareness campaigns in partnership with local community organizations. These campaigns should focus on testing, treatment, and PrEP to ensure that Aboriginal and Torres Strait Islander communities have equal access to HIV prevention and care.
