Reducing lethal violence against women requires comprehensive measures addressing individual, social, economic, cultural, and situational factors. Regarding situational factors, access to weapons—and firearm access in particular—has received notable research attention. However, most study comes from the United States of America, and findings may not apply elsewhere. The current study examines whether changing gun laws in Australia affected female firearm homicide victimization. Female firearm homicide victimization may have been affected; however, no significant impacts were found for male firearm homicide victimization. Findings suggest there may be value in preventing legal access to firearms by persons who have a history of intimate partner violence, although considerable further study is required.
