The Australian Defence Force (ADF) will allow recruits from foreign countries, including the UK, to help grow its ranks.
Australia has been struggling with enlistment shortfalls, as it seeks to beef up its armed forces in the face of what it says are growing regional threats.
From July, New Zealand nationals who are permanent residents of Australia can apply to join, and from next year that will expand to recruits from the UK and other countries including the US and Canada.
