The latest rotation of US Marines has touched down in Darwin as they prepare to join Australian soldiers in training in “humanitarian assistance, security operations, and high-end live fire exercises”.

The 2500 member strong Marine Rotational Force-Darwin will spend the next seven months working closely with their Australian counterparts as well as other partner nations from around the region.

It comes on the back of last week’s announcement of the AUKUS nuclear submarine deal, and Deputy Prime Minister Richard Marles said the US continued to be Australia’s “most vital security partner”.

“Over the next six months, the Australian Defence Force and US Marine Corps will conduct a comprehensive range of training activities including humanitarian assistance, security operations, and high-end live fire exercises."

Australia needs to have a more honest conversation, with itself and its main ally, about the b-word. As a straight-talking country that prides itself on its closeness to the United States, Australia finds it curiously difficult to talk in plain terms about foreign military basing on its territory, at least in public. It’s an interesting kink in the country’s strategic psyche—and one that needs straightening out sooner rather than later.

As the defence strategic review announcement and AUKUS submarine decision are pending, Canberra should develop clear, plain language that eschews euphemism when talking about the US’s forward posture and associated basing arrangements in Australia.

First contracts have been awarded for construction of a $120m bulk fuel storage facility at RAAF Base Tindal.

California joint venture Nova Nacap was awarded the US$80m contract to construct two jet fuel storage tanks at Tindal.

As well as the tanks, the works contract includes construction of an aircraft liquid fuel truck fill stand, fuel unloading stand, pump houses and filter building.

The tanks are being built in part to provide fuel for expected B-52 deployments by the United States into Australia.

Work is expected to get under way next year and be completed by February 2025.

More than 60,000 people quarantined at Howard Springs during the height of the pandemic. But the Defence Department is now considering using the facility to house thousands of military personnel during training exercises.

The Defence Department has now confirmed it is in negotiations with the Northern Territory government about leasing the facility.

"Potential future use options for the site have been canvassed during routine discussions between Defence and the Northern Territory Government," a defence spokesperson said.

Hospitality NT, which represents many of Darwin's hotels, said demand during the dry season is so strong that hotel rooms will be filled by tourists even if military personnel are housed at Howard Springs. "During the dry season, any large surge in military or government can absolutely impact other tourists," the organisation's CEO Alex Bruce said.

Secretary of Defense Lloyd Austin said Tuesday that the US will increase its military presence in Australia in a buildup aimed at China.

In a joint press conference with Australia’s defense minister and foreign minister, Austin said that the US will increase its rotational forces in Australia. “That includes rotations of bomber task forces, fighters, and future rotations of US Navy and US Army capabilities,” Austin said.

Many countries in the region are not eager to get on board with the US’s confrontational approach to China. The prime minister of Papua New Guinea said this week that his country can’t afford to get caught between the US and China and said he told the US your “enemy is not my enemy.”

Indonesia’s president expressed similar concerns during a meeting of the Association of Southeast Asian Nations (ASEAN) in November, saying the ASEAN must not let the region turn into a frontline for a new Cold War.

Details on the rotational deployments aren’t clear, but they will likely focus on the Australian city of Darwin in the Northern Territory, where US Marines have been rotating through for years.
