The national significance of key Northern Territory infrastructure assets has been singled-out in a crucial new defence review released on Monday.

The Defence Strategic Review found recent severe flooding which closed the Stuart Highway and Alice Springs to Darwin railway this year had “highlighted the importance” of well-maintained resilient civil infrastructure, including ports and roads that support the network.

The future role of Robertson Barracks, home to the 1st Brigade, in our ongoing defence is unclear, but could potentially be beefed up.

The report forecasts “significant changes to army force posture and structure”, saying army combat brigades “may be re-roled and select capabilities postured in Northern Australia”.

One of six key recommendations is to improve the Australian Defence Force’s capacity to operate from Australia’s northern bases.

With construction deadline looming, engineering contractor Saunders International has been removed as lead builder for the A$270m US military bulk fuel storage facility at East Arm.

The project was originally scheduled for completion by September 15, but that is now likely to be delayed until later this year.

The announcement comes as workers put the lid on the final tank this week.

The Darwin bulk fuel storage facility represents a $270m investment in the Northern Territory.

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.

The head of the ADF's Space Command says Australia is working on a plan to take out enemy satellites without creating dangerous debris.

Last year, top ranking members of the US Space Force described Australia as a "pot of gold at the end of the rainbow", saying the country's geography was "prime" for future space operations.

"Geography is really important. We need to be able to see to protect, and we can see a lot from here," Vice Admiral Roberts said.

"And that goes for non-kinetic effects from the ground too, because it's what you can see and where you can effect it".

once again, our strategic direction dovetails perfectly to USA demands
