What happened
In the Country of the Gunditjmara people in south-western Victoria, generations of engineers cut and stacked the region's volcanic basalt, formed by the Budj Bim eruption, into an extensive network of channels, weirs, and dams. The system diverted water between wetlands and lake basins to trap kooyang, the short-finned eel, as water levels rose and fell, providing a reliable year-round food supply. Radiocarbon dating shows construction began at least 6,600 years ago, and the surrounding area also holds the remains of almost 300 stone house foundations, evidence of a settled, non-nomadic community sustained by the harvest.
Why it matters
The engineering let the Gunditjmara build permanent settlements and trade surplus eels rather than living as purely mobile hunter-gatherers, contradicting older assumptions that Aboriginal societies were uniformly nomadic before colonisation. In 2019 Budj Bim became the first Australian site added to the UNESCO World Heritage List solely for its Aboriginal cultural values, after a campaign the Gunditjmara ran for decades.
How we know
Archaeological survey and radiocarbon dating of the constructed channels and adjoining habitation sites, combined with Gunditjmara oral tradition describing the eel harvest, underpinned both academic publication and the UNESCO nomination.
