Each year, AFAO provides a snapshot of what HIV looks like in Australia. This resource, HIV in Australia, provides the most up to date epidemiological data in the form of a straightforward infographic.
Total HIV diagnoses
- The number of HIV notifications newly diagnosed in Australia has remained stable for the past four years, with 1,066 notifications in 2012, 1,030 in 2013, 1,084 in 2014, 1,027 in 2015 and 1,013 in 2016.
- Overall, no jurisdiction has observed a long‑term decreasing trend in the past ten years.
- The main route of HIV transmission in Australia continues to be sexual contact between men, which accounted for 70% of notifications in 2016, a further 21% of cases were attributed to heterosexual sex, 5% to sexual contact between men and injecting drug use, 1% to injecting drug use only, and 3% to other/unspecified.
- Among notifications attributed to heterosexual sex, 17% were in people born in countries recognised by UNAIDS as having a national prevalence above 1% (high prevalence), and 17% in people with sexual partners born in high prevalence countries.
- Based on tests for immune function, over a quarter (33%) of the new HIV notifications in 2016 were late. This means that they were in people likely to have been living with HIV for at least four years without being tested.
- Over the last five years the proportion with late diagnoses was highest in people born in Central America (45%), sub‑Saharan Africa (43%) and Southeast Asia (43%). Over ten years, there was a decline in the proportion with late diagnoses among men engaging in male‑to‑male sex or male‑to‑male sex and injecting drug use (21% to 25%).
Aboriginal and Torres Strait Islander diagnoses
- Based on 46 cases, the age standardised rate of HIV notification in 2016 among Aboriginal and Torres Strait Islander peoples was more than double the rate in the Australian‑born non‑Indigenous population (6.4 versus 2.9 per 100 000).
- In the most recent five year reporting period (2012 – 2016), a greater proportion of HIV notifications in the Aboriginal and Torres Strait Islander population were attributed to heterosexual sex (20%) or injecting drug use (14%), compared with the Australian‑born non‑Indigenous population (15% and 3% respectively).
- Among 233 children born to HIV-positive mothers in Australia in the five year period 2012 – 2016, the transmission rate to newborns was 2%, compared to 28% in the period 1992 – 1996.
