India, Australia forge defence ties to check China’s Indo‑Pacific ambitions

India and Australia’s defence relationship is evolving into a forward-looking partnership designed to manage the challenges posed by China’s assertiveness in the Indo-Pacific. The emphasis is on practical, scalable arrangements rather than rigid alliances, allowing both countries to adapt cooperation to shifting regional dynamics. Defence Minister Rajnath Singh’s recent visit underscored this calibrated approach, highlighting interoperability and crisis management as central goals.

The logistics support agreement is a transformative step, enabling reciprocal access to bases and joint deployments across the Indian Ocean and Pacific. This arrangement sustains naval operations far from home waters—a critical capability for countering Chinese maritime expansion. Complementing it, joint exercises such as AUSINDEX and Malabar have expanded in scope to include advanced anti-submarine warfare and coalition operations. These drills rehearse collective deterrence and signal that unilateral attempts to dominate sea lanes will meet coordinated resistance.

Maritime domain awareness is another pillar of cooperation. Both countries are investing in satellite surveillance and information-sharing mechanisms to track Chinese naval movements, illegal fishing, and grey‑zone activities. Greater transparency reduces the risk of surprise manoeuvres and strengthens regional resilience. Defence-technology collaboration is also gaining traction, linking Australia’s undersea-warfare expertise with India’s growing defence-industrial base. This cooperation lowers dependence on Chinese-controlled supply chains and builds indigenous capacity.

India’s Army Chief Upendra Dwivedi’s recent visit to Australia broadened the relationship further, focusing on army-to-army cooperation, professional military education, and interoperability. Engagements with senior Australian defence leaders highlighted joint planning and multi-domain operational frameworks, reinforcing strategic alignment.



Looking ahead, India and Australia are likely to routinise these arrangements, embedding them into regular operational practice. The trajectory points to a partnership that is operationally meaningful and strategically consequential, helping ensure the Indo-Pacific remains multipolar and resistant to coercion. By steadily deepening cooperation across naval, army, technology, and intelligence domains, the two countries are positioning themselves as key architects of regional stability in the face of China’s growing assertiveness.
