A leading think tank, the Australian Strategic Policy Institute, has called for Australia to adopt an “unconventional deterrence” strategy to counter rising threats from China and Russia. This approach includes learning from historical guerrilla tactics and implementing “poisonous shrimp” or “porcupine” strategies to effectively address modern “grey-zone” tactics while mitigating defense gaps prior to the arrival of new submarines. The emphasis on unconventional means highlights the evolving nature of defense strategies as nations face asymmetric threats. This development underscores the importance of innovative approaches in national security, particularly for countries like Australia that are navigating complex geopolitical landscapes in the Indo-Pacific region.
