Dr. Tai Loureiro stood on the windswept coast near Perth, where the Indian Ocean meets the city’s southern edge, thinking not just of tides and currents, but of data—how it’s gathered, who uses it, and whose knowledge is included. As a marine biologist and ocean governance expert at The University of Western Australia’s Oceans Institute, she’s helping build a new kind of compass for Australia’s relationship with its vast marine estate: Ocean Accounts. This isn’t about assigning a dollar value to the sea, but about weaving together ecological health, economic activity, cultural significance, and governance into a unified evidence base. With Australia stewarding one of the largest marine jurisdictions in the world—from the tropical reefs of the Coral Sea to the temperate kelp forests of the Great Southern Reef—decisions can no longer afford to be made on fragmented data. The new national roadmap, shaped by Loureiro and a cross-sector team, aims to change that.
The Ocean Accounting White Paper, one of 21 shaping the National Marine Science Strategy 2026–2036, lays out a vision where marine science doesn’t just inform policy—it integrates with it. This work culminated in a peer-reviewed implementation roadmap published in the Australian Journal of Maritime & Ocean Affairs, co-authored by Rowan Trebilco and others. At its core is the idea that oceans support far more than fisheries and shipping; they provide food security, climate regulation, coastal protection, recreation, and deep cultural connections—especially for First Nations communities. The roadmap stresses that Indigenous, traditional, and local knowledge must be included, but only where communities choose to share it, and where data sovereignty and cultural protocols are respected.
Australia already leads in marine science, yet critical information on ecosystem health, economic use, and social value has long lived in silos. Ocean Accounts create a shared framework to connect these dots. The roadmap outlines a phased approach: strengthening data coordination in the short term, standardizing accounts across states and territories in the medium term, and ultimately producing routine, comprehensive national Ocean Accounts. This shift moves beyond GDP-style metrics, recognizing that a healthy ocean isn’t just an economic asset—it’s a foundation for well-being, equity, and resilience.
The University of Western Australia’s role underscores how academic institutions can bridge science and policy. As the nation prepares for the next decade of marine priorities, this effort signals a broader transformation—one where decisions about ocean use reflect not just what we extract, but what we protect, who benefits, and how we govern together. The ocean, Loureiro reminds us, is not a spreadsheet. It’s a living system, and our systems of knowledge must reflect that complexity.
