Canberra, 13 April 2026 – The Australian government has announced a major overhaul of senior leadership positions in the Australian Defence Force (ADF), with Lieutenant General Susan Coyle set to become the first woman to command the Australian Army in its 125-year history.
Prime Minister Anthony Albanese and Defence Minister Richard Marles made the announcement on Monday, describing Coyle’s appointment as a “deeply historic moment.” Coyle, currently serving as Chief of Joint Capabilities, will assume the role of Chief of Army in July 2026, succeeding Lieutenant General Simon Stuart upon his retirement.
A Milestone for Gender Representation
“From July we will have the first ever female Chief of Army in the Australian Army’s 125-year history,” Prime Minister Albanese stated. Defence Minister Marles added that the appointment was significant not only for women currently serving in the ADF but also for those considering a military career. “As Susan said to me, you cannot be what you cannot see,” he remarked.
Coyle’s elevation marks the first time a woman will lead one of the three service branches — Army, Navy, or Air Force — in the ADF.
Broader Leadership Changes
The reshuffle includes other key appointments:
- Vice Admiral Mark Hammond, the current Chief of Navy, will become the next Chief of the Defence Force.
- Rear Admiral Matthew Buckley is expected to take over as the new Chief of Navy.
These changes come as the ADF continues to modernise its capabilities amid regional security challenges, including commitments under AUKUS and priorities outlined in the Defence Strategic Review.
Lieutenant General Susan Coyle’s Distinguished Career
Lieutenant General Susan Coyle AM CSC DSM enlisted in the Army Reserves in 1987. She graduated from the Royal Military College in 1992 into the Royal Australian Corps of Signals after completing a science degree at the Australian Defence Force Academy.
With nearly four decades of service, Coyle has extensive experience at tactical, operational, and strategic levels. Her command roles include:
- Commander Joint Task Force 633
- Commander Forces Command (2022–2024)
- Head of Information Warfare
- Commander 6th Brigade
- Commander Task Group Afghanistan
- Commanding Officer 17th Signal Regiment
She has deployed on operations to the Solomon Islands, Afghanistan, Timor-Leste, and the Middle East. In July 2024, she was appointed Chief of Joint Capabilities, becoming the first woman to lead a “war-fighting domain” in the ADF, overseeing critical areas such as cyber, space, and information warfare.
Coyle holds several honours, including Member of the Order of Australia (AM), the Conspicuous Service Cross (CSC), and the Distinguished Service Medal (DSM).
Context Within the ADF
Women currently comprise approximately 19–21% of the ADF workforce. While previous milestones include the promotion of women to three-star ranks, Coyle’s appointment represents a significant step forward in leadership diversity.
The ADF has been working to address cultural challenges, including past allegations of sexual harassment and discrimination, while focusing on improving recruitment, retention, and operational readiness in an increasingly complex strategic environment.
In her own words, Coyle expressed humility and commitment: “As I prepare to assume this next appointment, I do so with humility, a deep appreciation for the experiences I have been afforded, and an unwavering commitment to steward our people well.”
The new leadership team is expected to guide the Army and broader ADF through a period of transformation, with emphasis on integration of advanced capabilities and preparedness for potential future threats.
