Southwest Victoria's Budj Bim cultural landscape hosts a complex system of channels, weirs and dams internationally recognised by UNESCO as the largest and oldest aquaculture network in the world.
Here, at Tae Rak (Lake Condah), its wetland swamps and the lava flows from the inactive Budj Bim volcano, the Gunditjmara people have harvested kooyang, or short-finned eel, for more than six millennia.
The traps diverted water from the lake into holding ponds, which were naturally formed lava sinkholes.
