United States Force Posture Initiatives

The United States Force Posture Initiatives (the Initiatives) are an extension of Australia’s existing Defence alliance with the United States (US). The objectives of the Initiatives are to improve interoperability between Australian and US armed forces, provide opportunities to engage with partners in the Indo-Pacific, promote regional stability, and better posture both nations to respond to contingencies such as humanitarian assistance and disaster relief operations. The Initiatives are a key component of the alliance and include the Marine Rotational Force – Darwin and Enhanced Air Cooperation.

The Commanding General of US Marine Corps Forces, Pacific, Lieutenant General Terry Robling, visited Robertson Barracks on Tuesday, 22 April 2014 to meet Marines currently deployed with the Marine Rotational Force – Darwin.


Australia’s alliance with the US is our most important Defence relationship and central to Australia’s strategic and security arrangements. The Initiatives are a key component of this alliance.
