Ongoing concerns about the impact of climate change on Australia’s oceans has driven a desire for improved communication of impacts to the seafood sector. Despite these concerns, translating climate science into management and industry action at regional and sectoral scales remains a challenge. Here, we developed a framework for communicating climate and ecosystem status to Australian federal fisheries management, industry, and research stakeholders. Our framework integrates historical climate impacts, ecosystem indices derived from observing programs, on-the-water observations from industry, and forecast outlooks tailored for the upcoming fishing season. We applied the framework across 10 diverse fishery case studies, spanning multiple spatial scales and regions (from the Bass and Torres Straits to sub-Antarctic islands to the continental EEZ) and target species traits (encompassing benthic invertebrates, demersal fish and sharks, and pelagic billfish and tunas). We describe the framework structure, the climate and ecosystem indices used, as well as some emergent themes that arose from the development and dissemination of reports. Some of these themes include the utility of subseasonal-to-seasonal forecasts, positioning climate science amidst perceptions of certain species as ‘climate winners’, and harnessing qualitative on-the-water observations to address data availability limitations. The lessons learnt and general framework can be applied to the development of other climate and integrated ecosystem reporting activities that are ongoing around the world. We contend that these reports serve as important tools for fostering climate resilience and facilitating the adaptation of the Australian seafood sector to the dynamic challenges of a rapidly changing ocean ecosystem.
