David Johnston named as new chief of defence force

"Vice Admiral Johnson has consistently distinguished himself with his capacity to ensure that different elements of defence work together," he added.

"His understanding of integrated defence will be critical to delivering on the priorities and recommendations of the defence strategic review, ensuring our defence force has the right capabilities and the right leadership to meet the challenges ahead."

Vice Admiral Johnston joined the military in 1978 and was named vice-chief of the defence force in 2018, previously serving in Iraq and Afghanistan.
