This report details the findings from a nationwide survey of sexuality and gender diverse Australian secondary school students, entitled the Free2Be? project. The name, while also intended to be catchy and easy for young people to remember, was designed to address the fundamental project questions for participants: Is school a place where it is safe to be yourself?; Are you free to be you? The project’s core aims were to; 1) gain a better understanding of how sexuality and gender diverse students experience their school’s ethos, referred to here as school climate, with regards to sexuality and gender diversity in the broad sense, and to 2) investigate links between students’ reported school climate and various measures of their school wellbeing and associated academic outcomes. This research complements and extends numerous recent Australian studies which highlight both the structural discrimination experienced by some sexuality and gender diverse students, as well as the positive impact of a supportive school environment, as experienced by others.
