Australia's Deputy Prime Minister and Defence Minister Richard Marles is set to travel to India later this week for the second Australia-India Defence Ministers' Dialogue, where he is scheduled to meet Defence Minister Rajnath Singh. The visit marks a significant milestone in the rapidly deepening bilateral security relationship between the two nations.

What Marles Said Ahead of the Visit

'Australia and India are top-tier security partners. I look forward to meeting with Defence Minister Rajnath Singh to further strengthen our defence partnership following the strong progress we made during his visit to Australia last year,' Marles said in a statement released by the Australian Defence Ministry ahead of the trip.

Singapore Stop Before India

Marles is first heading to Singapore to attend the 23rd Shangri-La Dialogue, convened by the International Institute for Strategic Studies (IISS), scheduled from 29-31 May. At the forum, he will address regional maritime security challenges during the third plenary session on Asia's Maritime Security Disorder and hold meetings with global and regional defence counterparts.

Growing Bilateral Defence Momentum

The first Australia-India Defence Ministers' Dialogue was held in Australia in October 2024, with the Australian Defence Ministry describing the series as evidence of 'unprecedented progress' in the bilateral defence partnership. Most recently, on 8 May, the two countries conducted the 10th edition of Defence Policy Talks in New Delhi, where officials on both sides welcomed the increased frequency and complexity of joint military exercises.

'The establishment of the annual India-Australia Defence Ministers' Dialogue in 2025 has enhanced consultation and reflected the growing trust between the two countries,' the Ministry of Defence said in a statement following the Policy Talks. The Indian delegation was led by Joint Secretary Amitabh Prasad, while the Australian side was headed by First Assistant Secretary, International Policy, Bernard Philip.

Strategic Foundation of the Relationship

According to the Ministry of External Affairs (MEA), India-Australia ties are underpinned by shared democratic values, Commonwealth traditions, expanding economic engagement, and increasing high-level interaction. Both nations have reaffirmed their commitment to deepening maritime cooperation and fostering regional stability — a shared priority that has gained urgency amid shifting Indo-Pacific dynamics.

Notably, this is only the second edition of what is now an annual dialogue format, signalling that the institutional architecture of the defence partnership is still being built — and being built quickly. With Marles' India visit following immediately after a high-profile multilateral security forum, the optics underscore how central the India relationship has become to Australia's regional strategy.
