The US Marine Corps Initiative involves the rotation of US Marines through northern Australia during the six month dry season (typically April – September). In its mature state, the Marine Rotational Force - Darwin (MRF-D) will be a Marine Air-Ground Task Force of around 2500 personnel with a variety of aircraft, vehicles and equipment. While in Australia, the Marines undertake a range of training activities including bilateral training with the Australian Defence Force (ADF) and independent training at existing Defence facilities. Visit the United States Marine Corps Initiative for more information.
The Enhanced Air Cooperation (EAC) Initiative will develop over a number of years and result in increased rotations of US Air Force elements through northern Australia. The initiative will enhance bilateral collaboration and offer greater opportunities for combined training and exercises. The details of EAC are being discussed between the Australian and US governments.
The treaty-level Force Posture Agreement between Australia and the US provides a framework for how the two nations will collaborate on force posture initiatives. It was signed at the 2014 Australia-United States Ministerial Consultations and came into effect on 31 March 2015.
The Force Posture Agreement enables US forces to have a presence in Australia and perform activities such as security operation exercises, joint and combined training exercises, humanitarian assistance and disaster relief as agreed with Australia. The Agreement does not allow for permanent US military bases in Australia. US forces will be hosted at existing Defence sites like Robertson Barracks and RAAF Base Darwin.
