The Indo-Pacific has become the most strategically contested region of the twenty-first century, shaped by the growing rivalry between the United States and China. In such an environment, middle powers have acquired renewed significance as they seek to safeguard their interests without directly challenging or aligning fully with great powers. This paper examines Australia’s foreign policy as a leading example of middle power diplomacy in the Indo-Pacific. It investigates the structural dilemma created by Australia’s dependence on the United States for security and its reliance on China for economic growth. Drawing on theoretical debates on middle power behaviour, the study analyses Australia’s evolving diplomatic strategies, including its participation in AUKUS and the Quad, and its diversification through closer engagement with India, Japan and ASEAN. The paper argues that while Australia continues to project itself as a middle power through multilateralism, coalition-building and norm entrepreneurship, its autonomy is significantly constrained by asymmetric interdependence. The conclusion suggests that Australia’s diplomacy illustrates both the possibilities and the limits of middle power agency in a polarised regional order. Middle power diplomacy in this context is less about achieving independence and more about managing contradictions, which makes the Australian experience an important case study for other states navigating similar pressures.
