The high rates of suicide-related behaviour among Aboriginal and Torres Strait Islander people, combined with similar evidence relating to LGBTQIA+ people, suggest that there is a need to investigate the compound risk of suicide-related behaviour among people who are both Aboriginal and Torres Strait Islander and LGBTQIASB+. This report highlights gaps in existing data collection and research literature regarding the experiences of this group. It explores the risks to social, cultural and emotional wellbeing, as well as protective factors for suicide, for this group. Further research is needed to improve policy, data, and program service response, particularly following the impacts of the COVID-19 pandemic and government responses. This review recommends that Aboriginal and Torres Strait Islander LGBTQIASB+ people are treated as a priority group for research, policy and programs that are informed, owned, and driven by Aboriginal and Torres Strait Islander LGBTQIASB+ people.
