A national vision for science-enabled coastal and urban development in Australia

Abstract

Australia’s coastal regions underpin national prosperity, community well-being, and cultural identity but face accelerating pressures from climate change, population growth, and development. This paper presents a national science framework to strengthen the resilience and sustainability of coastal development and associated services in Australia through integrated, science-based approaches operating across jurisdictions and sectors. Drawing on current evidence and practitioner insight, it identifies major knowledge gaps in understanding coastal and ecosystem processes, predicting climate- and human-driven change, designing adaptation options, and integrating socio-economic, Indigenous, and governance dimensions into planning. These gaps inform priority actions to support coordinated progress over the coming decade. The paper highlights the need for shared observation and modelling infrastructure across government, industry, and research; interoperable and accessible data platforms; enhanced workforce capability; and stronger cross-jurisdictional governance to reduce fragmentation in planning and policy. It emphasises Indigenous knowledge, cross-disciplinary collaboration, and co-design with communities and end users to translate science into effective decisions. Implementation pathways are outlined to strengthen governance, improve knowledge transfer, and define clear indicators of societal and scientific impact. Together, these priorities provide a coherent foundation for nationally-coordinated action to support resilient coastal communities, sustainable development, and healthy coastal ecosystems for generations to come.
