Australia could soon be hosting more US marines and warships with Defence Minister Peter Dutton declaring he wants even greater military cooperation with our closest ally.

Senior officials from both nations are discussing options for expanded military cooperation, which the ABC has learnt include a proposal to form a new joint US marines and ADF training brigade based in Darwin.

If established, the joint brigade would be the first of its kind for Australia and would likely involve a rotating command with the United States.

Mr Dutton agreed there was scope to increase the size of the US marine rotational force in the Top End from its pre-COVID level of 2,500, and to base US navy vessels at HMAS Stirling near Perth. acting US ambassador Michael Goldman declined to comment on whether more American marines could soon be heading to Australia.

JAPANESE troops have arrived in Darwin ahead of the trilateral Exercise Southern Jackaroo 2021, joining US Marines already undertaking training in the region.

The Japan Ground Self-Defense Force (JGSDF) soldiers will join their counterparts from Australia and the United States for the exercise in the Northern Territory June 15-25.

“The Japan Ground Self-Defense Force and the Marine Rotational Force – Darwin will bring more equipment this year, allowing for a more complex exercise to advance our ability to work together,” Lieutenant General Burr said.

A US Marine in the NT has tested positive for COVID-19 while in quarantine.

The 19-year-old man arrived in Darwin on May 9 and tested positive in the past 24 hours.

The patient is asymptomatic and is under the care of NT Health at the NT Centre for National Resilience.

The total number of cases diagnosed in the Northern Territory is 172.

All cases have been related to international or interstate travel, with no cases of community transmission.

Australia will invest $582 million to improve bases and training areas in its Northern Territory that are used by a rotational force of U.S. Marines, the country’s Defence Department announced Wednesday.

The country’s defense minister, Peter Dutton, said the upgrades will ensure that the Australian Defence Force delivers world-class training and engagement with allies and other nations through joint exercises, including with the Marines.

The announcement comes amid deteriorating relations between Australia and its largest trading partner, China.

“These new initiatives should help to make northern Australia an even more attractive location for many types of training and exercising by United States forces,” according to Ross Babbage, a former Australian assistant defense secretary.

THE build up of the US Marine Air-Ground Task Force in Darwin moved into overdrive this week with a squadron of MV-22B Ospreys, a detachment of UH-1Y Venoms and AH-1Z Vipers from Marine Light Attack Helicopter Squadron 367 joining a new tranche of 300 US Marines who touched down in the Top End.

Other heavy fighting equipment involved in the rotation includes an artillery battery from 3rd Battalion, 11th Marine Regiment; a detachment from 1st Combat Engineer Battalion; a detachment of RQ-20B Pumas and RQ-21A Blackjacks from Marine Unmanned Aerial Vehicle Squadron 3; and a collection of transportation and engineering assets from Combat Logistics Battalion 7.

More than 1300 US military personnel are now in Darwin as part of the 10th Marine Rotational Force – Darwin (C). This will grow to 2200.
