Policy fit: lessons from ocean governance in Australia

Abstract Achieving policy change in complex governance systems remains a persistent challenge, particularly where transformative integration is needed but institutional resistance is strong. This paper introduces policy fit as a novel approach comprising three dimensions: structural compatibility, shared understanding, and systemic responsiveness. Through analysis of Australia’s attempts at integrated ocean management (IOM); Integrated Coastal Zone Management (ICZM) and Australia’s Oceans Policy (AOP), we demonstrate how policy fit serves as both a diagnostic tool for identifying barriers to effective change and a design principle for achieving meaningful integration within existing constraints. These cases reveal that ambitious policies lacking alignment across the three dimensions inevitably encounter insurmountable resistance from entrenched institutions, cognitive fragmentation, and veto points. Policy fit offers practitioners a strategic incrementalist pathway that works with, rather than against, existing governance structures, enabling sustainable integration through calculated alignment rather than wholesale institutional restructuring. This approach represents a vital alternative to transformative policies that encounter insurmountable institutional resistance, offering instead a pragmatic path toward sustainable policy change in complex systems.
