Australia Appoints First Female Army Chief in Military Leadership Reshuffle

Apr 13, 2026

Australia announces Lieutenant General Susan Coyle will become the country's first female army chief in July, marking a historic milestone in the Australian Army's 125-year history. The 55-year-old Coyle, currently chief of joint capabilities with nearly four decades of military experience including operations in Afghanistan and the Middle East, will replace Lieutenant General Simon Stuart who assumed the role in July 2022. Defence Minister Richard Marles called the appointment deeply historic as part of a broader leadership reshuffle that includes Vice Admiral Mark Hammond becoming head of the Australian Defence Forces. The appointment comes as the military faces a class action lawsuit filed in October alleging failure to protect thousands of women from systematic sexual assault and discrimination, while women currently comprise only 21 percent of the Defence Forces and 18.5 percent of senior leadership despite a 25 percent participation target by 2030.
