Australian Defence Force personnel are increasingly deployed to environments where sexual and gender-based violence (SGBV) is not incidental but systemic. They may respond to incidents, support survivors or observe consequences of sexual violence used as a weapon of war. There is also limited research on the effects of SGBV exposure on military members internationally. Moral injury was first recognised in military personnel returning from operations involving events that transgressed their core beliefs and values. SGBV exposure is not a fringe issue; it is an operational reality, and one that touches all military personnel.
