Deployments of Japanese F-35 fighter jets to northern Australia will be ramped up as part of a deepening of security ties between the two countries, while Anthony Albanese prepares to join Quad leaders for a summit in the US later this month.

Late last month, Tokyo lodged a diplomatic protest after a Chinese spy plane allegedly breached its airspace for the first time near the Danjo Islands in the East China Sea.

Shared concern by Australia and Japan over Chinese aggression prompted the signing of a landmark defence pact that came into force last year, making it easier for each country’s military to operate in the other nation.

At Thursday’s 2+2 talks, ministers are expected to expand the rotation of Japanese F-35 fighter jets for temporary basing in Australia, including joint exercises alongside US Marines in Darwin. Two Japanese jets were dispatched to Australia a year ago to test the viability of deployments.

In a strongly symbolic message, the talks will be held at Queenscliff, east of Geelong – home of the secretive Swan Island defence and spy training facility.

An emergency response at the Darwin Airport has been declared a false alarm after a pair of fire trucks raced across the tarmac to seemingly save a landed United States V-22 Osprey.

On Tuesday, morning, passengers and staff were left confused when the airport came to a stand still as two fire trucks entered the airstrip to pull up alongside the US Marine aircraft.

Civilian onlookers watched with anticipation, only for the fire and rescue teams to stand down and return to their bays, with airport operations resumed a short time later.

There was no emergency and no problem with the aircraft.

Mr Gosling said northern Australia’s defence would be seriously boosted by the Commonwealth’s $7-10bn investment in 18 medium landing craft and eight heavy landing craft, to be based in northern Australia.

Writing in the Australian Strategic Policy Institute’s Strategist magazine, the Top End’s federal MP said the strong focus on northern Australia in defence planning including the National Defence Strategy and Integrated Investment Program reflected the crucial role the region would play in defending the nation.

He said northern Australian bases would “have a key role to play in helping the ADF to recover from an attack and strike back at the enemy”.

He flagged East Arm as a potential site to base the Territory’s contingent.

“Picture the manoeuvres of the British and US planes that shot down Iranian missiles heading for Israel in April — only this time over the Arafura Sea, again.”

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.

The agreement was finalized during a joint U.S.-Australia meeting that included Austin and his defense minister counterpart from Canberra.

"Based upon today's talks, we will increase the rotational presence of U.S. forces in Australia," Austin said at a press conference at the State Department. "That includes rotations of bomber task forces, fighters and future rotations of U.S. Navy and U.S. Army capabilities."

The increased military presence in Australia comes after the U.S. and U.K. announced in September 2021 that they had agreed to school the Australians on the "extremely sensitive" technology of nuclear-powered submarines. The U.S. had previously shared the technology only with the British.
