Australia has seen success in managing the spread of HIV/AIDS, with a low prevalence in the general population. In 2017, the estimated prevalence was 0.1%, with a total of 38,172 cases diagnosed and around 27,545 people living with HIV. By 2020, this number had risen to 29,090 people living with HIV in Australia, with an estimated 9% undiagnosed. The main mode of HIV transmission in Australia is through sexual contact between men, which accounted for 63% of notifications in 2017 and 74% in 2016. Despite overall low rates, certain groups, such as Aboriginal and Torres Strait Islander people, transgender women, and overseas-born men who have sex with men, continue to be disproportionately affected by HIV/AIDS.

What You'll Learn
HIV/AIDS cases in Australia are low compared to other countries
The low prevalence of HIV in Australia is partly due to the country's successful management of the disease. In the mid-1980s, the Australian government launched a well-known advertising campaign featuring controversial television advertisements that garnered a lot of attention. This campaign, despite contributing to stigma, particularly in the gay community, is credited with helping to manage the spread of HIV. Additionally, the government piloted programs involving needle exchanges for intravenous drug users, which were crucial in keeping the incidence of the disease low.
The main mode of HIV transmission in Australia is sexual contact between men, which accounted for 74% of diagnoses in 2016 and 63% in 2017. However, it is important to note that other populations are increasingly affected by HIV, including Aboriginal and Torres Strait Islander people, overseas-born men who have sex with men (MSM), transgender women, and women. The transmission rate among Australian-born MSM has declined by 21% over the last decade, but it still remains the most common route of HIV transmission in the country.
While Australia has made significant progress in managing HIV/AIDS, there are still challenges. For instance, about 9% of people living with HIV in Australia were unaware of their HIV status in 2020, and about 44% of all new HIV cases that year were diagnosed late. Additionally, while there have been very few vertical HIV transmissions from mother to child, with only five cases in the last five years, it is still a mode of transmission that public health officials must consider. Overall, Australia's response to HIV/AIDS has been effective in keeping the number of cases low compared to other countries.

The first Australian case was in 1981
The first Australian case of AIDS was reported in 1981. The patient was a 72-year-old man who died in September of that year. However, the case was only diagnosed retrospectively in 1994. The man developed a prolonged illness, beginning in February 1981, characterised by anorexia, malaise, weight loss, and an episode of herpes zoster. In July, he experienced difficulty breathing and a productive cough. He was admitted to the hospital in August and diagnosed with Pneumocystis carinii pneumonia, which was identified through a transbronchial lung biopsy.
The first reported AIDS-related death in Australia occurred in Melbourne in July 1983. At the time, AIDS was a relatively new disease, and its emergence sparked public hysteria and vilification, particularly towards gay and lesbian communities, people who used illicit drugs, and sex workers. The Australian government recognised and responded to the AIDS pandemic relatively swiftly, implementing effective disease prevention and public health programs, including needle and syringe exchange programs.
In the mid-1980s, the Australian government launched a well-known advertising campaign featuring controversial television advertisements, including one with the grim reaper rolling a bowling ball towards a group of people. These advertisements were effective in raising awareness about AIDS and contributed to Australia's success in managing the disease. By 1985, all blood donors in Australia were screened for HIV antibodies to prevent the spread of infection through blood transfusions.
Despite these efforts, HIV/AIDS continued to spread in Australia, with new cases reported in the years that followed. In 1987, a man named Andre Chad Parenzee was convicted of intentionally transmitting HIV, securing widespread media attention. In 2009, Michael Neal was jailed for deliberately infecting and attempting to infect sexual partners with HIV, despite warnings from health authorities.
Today, AIDS is no longer considered a public health crisis in Australia due to the success of antiretroviral drugs and low HIV-to-AIDS progression rates. Australian governments have also made it illegal to discriminate against individuals with HIV/AIDS, although challenges remain in terms of immigration policies and stigma.

Antiretroviral drugs have improved survival rates
The prevalence of HIV infection in Australia has remained low, estimated at 0.1% in 2017. By the end of 2017, a total of 38,172 cases of HIV infection had been diagnosed in the country, with an estimated 27,545 people living with HIV in 2013. The annual number of new diagnoses has decreased by 7% in the last five years.
Antiretroviral drugs have played a significant role in improving survival rates for people with HIV in Australia and worldwide. Antiretroviral therapy (ART) is a combination of medications used to treat HIV by stopping the virus from reproducing. It can reduce HIV levels and keep the immune system healthy. While ART is not a cure, it can make HIV undetectable in the body.
The success of ART has transformed HIV/AIDS from a death sentence into a manageable chronic condition. Since its introduction in the late 1980s, ART has saved millions of lives globally. Studies have shown that a 3-drug regimen can lead to a 60% to 80% decline in AIDS rates, hospitalization, and death. The CDC plans to implement a 90-90-90 strategy by 2030, aiming for 90% of people with HIV to be diagnosed, on therapy, and virally suppressed.
In Australia, the introduction of antiretroviral drug treatments has contributed to improved survival rates and reduced the possibility of HIV progressing to AIDS. While infection rates rose after initial success in limiting the spread, they remain low by global standards. ART has been crucial in managing HIV in Australia, reducing transmission, and improving health outcomes for people living with the virus.
The effectiveness of ART relies on patient compliance with the treatment regimen. Healthcare professionals, including nurses and pharmacists, play a vital role in patient education, monitoring, and ensuring treatment adherence. ART has improved survival rates and quality of life for people with HIV in Australia, allowing them to live long and healthy lives.

HIV transmission is predominantly through sexual contact between men
HIV transmission in Australia predominantly occurs through sexual contact between men. While the spread of the disease has been relatively well-managed, with a low prevalence in the general population, men who have sex with men (MSM) remain a group disproportionately affected by HIV.
In 2017, the prevalence of HIV infection in Australia was estimated to be 0.1%, with a total of 38,172 cases diagnosed since the first case in 1981. The annual number of new diagnoses has decreased by 7% in the last five years, dropping below 1000 annual notifications in 2017. Despite this downward trend, the rate of new HIV cases in Australia increased from 656 in 2000 to 930 in 2005, with transmission predominantly through sexual contact between men.
Men who have sex with men are at a higher risk of contracting HIV due to several factors. Firstly, anal sex is riskier than vaginal sex for HIV transmission, as the virus can enter the body through the anus or rectal fluids of an infected person. Additionally, gay and bisexual men may face unique barriers in accessing preventative care, getting tested, and receiving comprehensive treatment due to social stigmas surrounding HIV and homosexuality.
To prevent the spread of HIV among men who have sex with men, it is crucial to promote the consistent use of condoms during sexual intercourse. Pre-exposure prophylaxis (PrEP) is also recommended for individuals who do not have HIV but have engaged in anal or vaginal sex within the past six months and have a sexual partner with HIV or have not consistently used a condom. Post-exposure prophylaxis (PEP), involving a short course of HIV medicines taken within 72 hours of possible exposure, is another effective measure to prevent the virus from taking hold in the body.
While the rate of HIV transmission through sexual contact between men remains a concern in Australia, the country has made significant strides in managing the disease. The willingness of the Australian government to address HIV/AIDS through blunt advertising campaigns and needle exchange programs for intravenous drug users has been credited as contributing to the country's success in keeping infection rates low compared to global standards.

HIV prevalence is higher among gay and bisexual men
HIV prevalence in Australia has remained low, with an estimated prevalence of 0.1% in 2017. However, within certain communities, the prevalence is higher. Between 2013 and 2017, sexual transmission between men accounted for 68% of newly diagnosed HIV infections in Australia, increasing to 82% of newly acquired infections. Gay and bisexual men in Australia have a higher prevalence of HIV, with 8% self-reporting HIV prevalence among men attached to the gay community.
There are various factors contributing to the higher prevalence of HIV among gay and bisexual men in Australia. Firstly, HIV infections among gay and bisexual men are often attributed to sex with new or casual partners. In a survey, 66.1% of recently diagnosed gay and bisexual men ascribed their infection to a casual partner, while only 10.6% believed they contracted HIV from a committed romantic relationship. This dynamic of casual partnerships and negotiated safety within relationships can increase the risk of HIV transmission.
Secondly, younger gay and bisexual men, bisexual men of all ages, and men living in suburbs with fewer gay residents are more vulnerable to HIV. They experience higher levels of HIV risk and lower levels of prevention coverage. This disparity is partly due to varying access to and use of HIV prevention strategies across different subpopulations. For example, men in suburbs with more gay residents have higher PrEP use, contributing to lower HIV rates.
Additionally, bisexual men and those with other identities are more likely to report consistent condom use compared to gay-identified men. Gay-identified respondents reported higher rates of condomless sex, including those with undetectable viral loads. This dynamic contributes to the higher prevalence of HIV within this community.
To address these disparities, experts recommend supporting access to a range of prevention strategies, including condoms, PrEP, and undetectable viral load approaches, rather than relying on single strategies. Increasing HIV prevention coverage among gay and bisexual men is crucial to reducing inequities and the overall prevalence of HIV in Australia.
