Australia wants Japan’s ‘cutting edge’ tech for Aukus – but not just yet

Despite being keen to see Japan’s collaboration, Marles indicated that it would not happen any time soon as Aukus is still “very much focused on working on new innovative technologies among the three countries”.

“As pillar two becomes more mature, which is going to take some years … I think there is an opportunity at that point to look at how we can cooperate with Japan in relation to that,” he said.

Canada and New Zealand have also expressed interest in working with Aukus members on pillar two.

Asked whether Tokyo should also consider acquiring nuclear-powered submarines, the Australian minister said it was “a matter for Japan” and he “would not seek to venture an opinion”.

Australia made a decision “in the context of our strategic needs”, Marles said, noting that “we desperately need a highly capable long-range submarine” as an island nation located far away from other countries.

Speaking on the bilateral defence relationship between Canberra and Tokyo, Marles noted that “Australia and Japan have never been more strategically aligned than we are now”.

The minister also welcomed the prospect of Japan using Australia’s vast continent as a testing ground for long-range missiles, as Tokyo seeks to acquire capabilities to strike targets in enemy territory.

“Our training areas are among the best in the world, and we’re very keen to work with Japan in relation to them, and see Japan have the opportunity to use them,” he said of Australia’s long-range test sites.

In a major defence policy shift for a country with a nominally pacifist constitution, Japan pledged to acquire “ counterstrike capabilities” in late 2022. It plans to develop home-made long-range missiles and procure US-produced Tomahawk cruise missiles.

Australia and Japan have been strengthening their defence cooperation in recent years, including signing a reciprocal access agreement that came into effect last August that enables quicker deployment of defence personnel between the two nations.

Marles reiterated the “strong ambition” on both sides to further the relationship, and said Australia is “keen to increase the tempo” of cooperation.
