Canberra is looking to forge closer ties with Tokyo within the Aukus security partnership, with a focus on joint technological advancements, according to Australia’s Defence Minister, Richard Marles. While ruling out Japan’s immediate involvement in the primary Aukus initiative of providing nuclear-powered submarines to Australia, Marles emphasized Australia’s interest in leveraging Japan’s innovation prowess.

Acknowledging Japan’s position as a leader in technological innovation, Marles highlighted the potential for enhanced cooperation between the US, UK, Australia, and Japan. The Aukus partnership, established in 2021 in response to China’s increasing assertiveness in the Indo-Pacific, is structured around two pillars: the acquisition of nuclear submarines and the development of advanced capabilities in areas like artificial intelligence and hypersonic missiles.

Despite Canberra’s enthusiasm for collaboration with Japan, Marles indicated that immediate involvement might not be feasible, given Aukus’ current focus on technological innovation among its core members. However, he expressed optimism about future opportunities for cooperation as the partnership evolves.

Regarding Japan’s potential acquisition of nuclear-powered submarines, Marles maintained a diplomatic stance, stating that it was a decision for Japan to make independently based on its strategic considerations. He emphasized Australia’s decision-making process in the context of its own strategic requirements, particularly the need for highly capable long-range submarines given its geographical isolation.

Highlighting the deepening defence relationship between Australia and Japan, Marles underscored the strategic alignment between the two nations. He welcomed Japan’s interest in utilizing Australia’s expansive territory for testing long-range missiles, noting the superior training facilities available in the country.

Japan’s recent policy shift towards acquiring “counter strike capabilities” marked a significant departure from its traditionally pacifist stance. This move includes plans to develop indigenous long-range missiles and procure Tomahawk cruise missiles from the US. The strengthening defence cooperation between Australia and Japan, including the reciprocal access agreement facilitating the rapid deployment of defence personnel, reflects the shared commitment to bolstering regional security.

Marles reiterated the mutual ambition to deepen defence ties between Australia and Japan, emphasizing Australia’s readiness to intensify cooperation. As both nations navigate evolving security challenges in the Indo-Pacific region, collaboration in advanced technology and strategic initiatives remains a key focus area for enhancing regional stability and security.
