India and Australia are set to significantly deepen their strategic partnership with a landmark understanding on long-term uranium supplies for India’s civil nuclear programme, alongside a series of agreements on defence cooperation, critical minerals, energy security and emerging technologies, sources said here ahead of Prime Minister Narendra Modi’s talks with his Australian counterpart.According to official sources, the two countries are expected to announce a “historic” uranium arrangement aimed at ensuring reliable fuel supplies for India’s expanding civilian nuclear energy programme, marking a major step in strengthening New Delhi’s long-term energy security.The two sides are also expected to broaden their energy partnership through increased Australian exports of liquefied natural gas (LNG), coal and diesel to India, complementing New Delhi’s efforts to diversify its energy basket amid growing geopolitical uncertainties.Defence cooperation is expected to emerge as another key pillar of the summit, with both countries likely to unveil a Joint Defence Declaration that will pave the way for greater defence industrial collaboration, interoperability between their armed forces and closer cooperation between defence startups and manufacturers through a proposed India-Australia Defence Innovation Corridor.The roadmap is also expected to place strong emphasis on counter-terrorism cooperation and enhanced collaboration across the Indo-Pacific.As part of efforts to strengthen maritime security, India and Australia are expected to adopt a Maritime Security Roadmap focusing on greater maritime domain awareness, coastal surveillance and information sharing across the Indo-Pacific region.In another first, an Indian Army officer is expected to be posted to the Australian Defence College, reflecting the growing level of military-to-military engagement between the two strategic partners.The summit is also likely to produce major outcomes in the critical minerals sector, with both sides expected to launch an India-Australia Critical Minerals Corridor aimed at securing resilient supply chains for minerals vital to clean energy technologies, electric vehicles and advanced manufacturing.The two countries are also expected to conclude the Australia-India Partnership for Advanced Critical Technology and Security (PACTS) agreement, providing a framework for cooperation in cyber security, critical technologies and resilient technology supply chains.Officials said the expected outcomes reflect the rapidly expanding Comprehensive Strategic Partnership between the two Quad members as they seek to strengthen regional security, economic resilience and trusted supply chains in the Indo-Pacific amid an increasingly uncertain global environment.
