aAdjusted model for females includes: sex overseas and current sex worker
bNot in the labour force includes both those who are unemployed and/or students
cAdjusted model for males includes: Aboriginal and/or Torres Strait Islander peoples, sex overseas, current sex worker and HIV status.
Data missing for: <5% of PrEP data; <5%-10% of employment data; 5–15% of Aboriginal and/or Torres Strait Islander peoples data; 10–15% of current sexworker data; 10%-20% of sex overseas data and injecting drug use data; 15- ≥20% of condom use data; and >20% of HIV data. Proportions are calculated using available data.
