Food insecurity is well documented in Australian university students and especially during the COVID-19 pandemic 2020-2022(1). At one large Sydney university in the final phases of the pandemic, October 2021 to May 2022, a convenience sample of 467 students reported a prevalence of food insecurity of 27.4%(2). The current study sought to conduct a cross-sectional survey to ascertain prevalence in a new cohort of students and staff attending the same large university in 2025-26. A convenience sample from the university community, aged 18 years or older and attending campus at least one day weekly, was recruited to complete an online survey from September 2025 to June 2026. Demographic characteristics including age group, gender, country of birth, postcode of residence to determine socioeconomic status, and classification as domestic or international student or as staff member were collected. The Household Food Security Survey module six-item questionnaire was employed to determine food security status. Additional questions on use of food banks and food choice determinants of cost, taste, healthiness and familiarity were included in the survey. Food security was categorised high food security, marginal food security, low food security or very low food security scored using the module instructions. Comparisons were made according to domestic or international student or staff and then the importance of food bank use and food choice determinants according to food security status. A sample of 383 participants were recruited, and a high prevalence of food insecurity was shown with 53% of 235 domestic students, 65% of 91 international students and 42% of 57 staff experiencing some food insecurity in the past three months. This included 43.5% of students with low or very low food security compared with 14.2% the in 2021/22. Thirty six percent of the food insecure had used the University food bank. Of participants with low or very low food security 75% ranked cost as a very important determinant of food choice compared with 48% of those with high food security (p<0.001). No differences were found for other food determinants. As this was a convenience sample it cannot be generalised to all students and staff, and it is possible this sample differed from the previous one recruited. However, it points to the high prices of food in Sydney and mirrors concerns in the general Australian community about costs of food being among their most important issues. While some interventions such as food banks have been trialled and frequented by the food insecure, they cannot be the sole response. A systematic approach to codesign of potential solutions by the university community is recommended and with sound evaluation to enable scale up and dissemination across the university sector.
