US, Australia to boost defense ties amid China's growing influence

The United States and Australia have agreed to enhance their defense collaboration in response to China’s increasing military presence in the Pacific. This decision came after U.S. Defense Secretary Pete Hegseth met with his Australian counterpart, Richard Marles, in Washington. During the meeting, Hegseth emphasized that Australia recognized “the gravity of maintaining a favorable balance of power in the region.” Marles stated that the U.S. military’s presence in Australia is expanding, noting that the increased cooperation is a reaction to what he described as “the biggest conventional military build-up by any country in the world since the Second World War in the form of China.” The two nations reportedly agreed to accelerate force posture initiatives at Australian bases, increase combined logistics efforts, and improve interoperability through joint exercises. These initiatives allow the U.S. military to train and store equipment in Australia, including the rotational deployment of aircraft and logistical support for U.S. vessels. While Australia does not permit foreign military bases on its territory, it hosts several key joint exercises and rotations of U.S. Marines in Darwin, a northern city. It remained unclear whether the new agreement would result in additional U.S. troop deployments in Australia. According to the Pentagon, the discussions also covered progress on defense industrial cooperation aimed at enabling shared capacity for guided weapons and next-generation capabilities. Hegseth noted that the two countries share a “strong alignment” in their national defense strategies. He underscored the importance of allies investing in their own security and ensuring that their capabilities complement each other. Australia has been strengthening its defense forces in recent years, focusing on enhancing its missile strike capabilities and forming deeper strategic alliances. Cooperation between the U.S. and Australia extends beyond bilateral relations, including the AUKUS defense pact with Britain. Under this agreement, American defense personnel are currently stationed at the HMAS Stirling naval base in Western Australia, which is scheduled to host a rotating force of U.S.-commanded submarines starting in 2027. Marles highlighted that the expanded cooperation involves multiple areas such as logistics, air forces, cyber, and space operations. He reiterated that the growing partnership is a direct response to China’s military buildup and stressed the importance of collaboration with the U.S. to maintain regional peace and stability. Australia has also initiated its largest military investment program to construct nuclear-powered submarines over the next decade under the AUKUS agreement with the U.S. and the U.K. However, critics have raised concerns about the uncertainty surrounding whether Australia will ultimately receive these submarines. In addition to the AUKUS pact, the U.S. Marine Corps has planned for a crisis-ready stockpile in Australia, according to AFP. This move underscores the ongoing efforts to bolster deterrence and readiness in the Indo-Pacific region. The evolving defense relationship between the U.S. and Australia reflects broader strategic considerations in countering China’s rising influence and maintaining a stable regional order.
