Despite the fact that access to contraception it is key to reproductive autonomy, initiating and continuing use of hormonal contraception in Australia can be costly and logistically challenging. This mapping review aimed to identify and comment on the number and accessibility of online platforms providing prescriptions for and supply of hormonal contraception within Australia. We found that despite addressing some of the identified barriers, these services are unlikely to be truly accessible to all consumers.

Zero new HIV infections could become a reality if HIV pre-exposure prophylaxis (PrEP) programs are successfully implemented but the World Health Organization recognises that large-scale roll out is challenging. We used implementation science research tools in novel ways to evaluate one of the world’s first national PrEP programs, to develop evidence-based recommendations for use across a range of settings to improve PrEP uptake and initiation. Adopting these recommendations could enable governments and societies to better address HIV prevention goals.

Our 5-year Queensland study demonstrates the potential for molecular surveillance to track the changing epidemiology, movement and antimicrobial resistance of Neisseria gonorrhoeae in Australia. This is increasingly important, because potential prevalent gonococcal strains are not captured well by current methods, and we found evidence of bridging from male-dominant networks to heterosexual networks, which has serious implications for current public health practise. Genotyping is also necessary to monitor the transiency of dominant genogroups to allow a more targeted and tailored approach to treatment.

This paper reports on the sexual behaviours of Aboriginal and non-Aboriginal adolescents who have come into contact with the Australian justice system and looks at factors associated with testing for sexually transmissible infections (STI) and HIV, and diagnosis of sexually transmissible infections. Findings suggest there are different factors associated with STI/HIV testing for Aboriginal and non-Aboriginal justice-involved adolescents. Sexual health education should start early and consider gender, cultural and sexual orientation differences.

Sexual transmission has been the main mode of HIV transmission, and data on sexual risk behaviours among factory workers from various industries are scarce in China. Sexual risk behaviours that showed associations with certain characteristics and experience of sexual debut were prevalent among factory workers in Shenzhen, China. There are massive labour forces in China, indicating an urgent need to strengthen sexual health education and promote safer sexual behaviours among factory workers.

Over the past decade, the rates of syphilis in pregnancy and congenital syphilis are continuing to rise in south-east Queensland (SEQ). Screening for syphilis during antenatal care is an important factor for prevention. In our study, SEQ healthcare providers identified system-level and individual-level barriers that prevent adequate screening. It is important that these barriers be identified and addressed to improve screening to promote maternal health and prevent congenital syphilis in SEQ.

What does health and wellbeing mean to transgender and gender diverse individuals in rural Australia? As the first study of its kind, the findings are complex; there are higher rates of discrimination and feelings of social isolation for those living in rural areas and yet many people also report positive experiences. This diverse range of experiences was unexpected and could inform policy changes for national health service models.

Young cisgender heterosexual men in Australia are the least likely population group to ensure barrier method use during casual sex. There is limited information about how these young men might be navigating sexual health conversations with potential partners, whereby findings note that they choose to avoid the discussion or expect women to take responsibility. There is need to focus on educating young men concerning their responsibility for sexual health in casual sex encounters.
