Abstract: Canberra’s exposure to great-power conflict is arguably more complex and ambiguous than during the Cold War. Drawing from scholarly literature on entrapment and recent developments in outer-space security, this article explores Australia’s position in a hypothetical US–China war over Taiwan. The shifting military balance in outer space, recent war games by the US military and regional trends in defence planning all raise the possibility of a scenario opening with Chinese cyberattacks against information networks shared between Australia and the USA. As a result of its growing dependency on space systems, Australia may be entrapped in a novel way which poses questions for scholars and policymakers. These findings should encourage further study of regional crisis management, with the need for a shared understanding of strategic behaviour in outer space and cybernetworks.
