As two prominent Indian Ocean states, India and Australia are cooperating closely in the region. Building cooperation helps to provide for a more secure maritime environment. By 2030, the Indo-Pacific region is expected to account for 21 of the top 25 sea and air trade routes; around two-thirds of global oil shipments; and one third of the world’s bulk cargo movements. So improving security will be crucial to protecting our prosperity. In this setting, it is not surprising that, being Indian Ocean states, defence engagement between Australia and India focuses on joint naval cooperation., writes Australian Defence Minister Kevin Andrews.
