Moving beyond sexual and reproductive health knowledge: an evaluation of a co-designed digital engagement tool to promote sexual and reproductive health among international students in New South Wales, Australia

Background This study evaluates the perceived impact and needed enhancement of a co-designed digital sexual and reproductive health (SRH) tool (‘the Hub’) developed to address SRH literacy gaps among international students (IS) in New South Wales, Australia. Despite Australia’s large IS population and recognition of SRH as a fundamental human right, many report limited exposure to SRH information and face barriers to navigating health systems and accessing SRH services in host countries. Methods A mixed-methods evaluation was conducted comprising an online survey (August–October 2024; N = 129) and a focus group discussion (FGD) with professionals working with IS (N = 11). Results Survey findings indicate high acceptability and perceived usefulness of the Hub, with over 80% of participants rating content, including on the Australian health system, as high quality and most endorsing its design, tone, and usability. Although IS knowledge of HIV prevention and STI treatment was generally strong, gaps persisted regarding asymptomatic STIs, contraceptive limitations, and health system navigation. Notably, despite high awareness and favourable peer norms toward condom use and STI testing, testing uptake remained low: fewer than one in five sexually active IS reported STI (17.8%) or HIV (19.4%) testing in the previous 12 months. Qualitative FGD findings highlighted support for broader promotion strategies, including pre-arrival and campus-based dissemination, alongside needed enhancements to service navigation and cost transparency for SRH services. Conclusion Overall, the Hub demonstrates feasibility and relevance as a digital intervention, though improved promotion and stronger linkage between knowledge and service uptake are essential to maximise public health impact.
