Australia appoints first-ever woman Army chief in 125-year history amid defence shake-up

Australia has named its first-ever woman army chief in 125 years, a landmark move that comes amid a broader overhaul of the country’s defence leadership.

Lieutenant General Susan Coyle will take over as Chief of Army in July, succeeding Lieutenant General Simon Stuart. Her appointment makes her the first woman to head any service branch in Australia’s military history.

Defence Minister Richard Marles called it a “deeply historic moment”, saying the decision would inspire both serving members of the Australian Defence Force and future recruits, particularly women considering a career in the armed forces.

Coyle currently serves as Chief of Joint Capabilities and brings nearly 30 years of experience. Since joining the army in 1987, she has been deployed in operations across the Solomon Islands, Afghanistan and the Middle East, while also holding several senior command positions.

Her elevation comes as Australia pushes ahead with modernising its military, focusing on advanced capabilities such as long-range strike systems, drones and cyber warfare. Coyle said her experience across these domains provides a strong foundation for the responsibilities of command.

Women currently make up around 21% of the Australian Defence Force, which has set a target of lifting representation to 25% by 2030. The appointment also comes at a time when the military continues to face scrutiny over allegations of harassment and discrimination.

In parallel changes, Vice Admiral Mark Hammond has been appointed Chief of the Australian Defence Force, while Rear Admiral Matthew Buckley will succeed him as head of the navy.
