Professor Peter Dean, Director, Foreign Policy and Defence at the United States Studies Centre; Dr Zack Cooper, Senior Fellow at the American Enterprise Institute; and Hayley Channer, Director, Economic Security at the United States Studies Centre provided insights from an international strategy simulation that was hosted by the Centre to test how political thresholds, perceptions of risk, and national strategic assumptions might affect collective responses to a multi-faceted contingency in the Indo-Pacific.  The Sydney International Strategy Forum brought together prominent thought leaders, policymakers and industry experts to tackle the big issues confronting Australia, the United States and the Indo-Pacific. From bolstering supply chain resilience to turning AUKUS into reality, the forum discussed the enormous opportunities and risks posed by such cross-cutting challenges and what they mean for the future of our region.  The forum was held at the Four Seasons Sydney on 1 November 2023.
