Why is this in the news?

The fifth edition of the India-Australia joint military exercise, AUSTRAHIND 2026, has commenced in Thiruvananthapuram, Kerala, from October 19 to November 1, 2026. This biennial exercise, themed on ‘Joint Sub-Conventional Operations in Island and Coastal Environment under Chapter VII of the UN Mandate,’ underscores the growing strategic partnership between India and Australia, particularly in the context of the evolving security dynamics of the Indo-Pacific region. The inclusion of an observer delegation from New Zealand further amplifies the exercise’s significance as a platform for multilateral defence cooperation.

Background
