Following talks in Melbourne last week, Prime Ministers Anthony Albanese and Narendra Modi have vowed to hold increasingly complex defence exercises, expand aircraft deployments from each other's territories and increase their information-sharing between militaries.
The two Indo-Pacific nations also finalised administrative arrangements which will allow Australia to export uranium to India for peaceful purposes, as India looks to meet a target of 100 gigawatts of nuclear energy capacity by 2047.
Albanese has called India a "top-tier security partner" for Australia. He added: "We undertake to consult on defence-related developments in the Indo-Pacific that affect our shared interests."
Prime Minister Modi added that the two nations were "two multicultural societies and two important ocean powers".
He said: "These similarities between us and our common world view inspire us to continue moving forward together with deep mutual trust."
The Indian PM was in Australia last weekend as the city of Melbourne hosted a 20,000-strong 'Melbourne Meets Modi' gathering at Docklands Stadium.
Both Australia and India are thought to share concerns about the global targetting of sub-sea cables and the way in which strategic waterways, such as the Straight of Hormuz, can be targetted in the wake of the war in Iran.
The two leaders were expected to discuss ongoing negotiations on a more comprehensive trade deal (than the partial one signed in 2022) that would tackle outstanding market access issues.
