The Brewarrina Fish Traps are an ancient Aboriginal fish trapping system located in New South Wales, Australia. Believed to be over 40,000 years old, these stone structures were designed to catch fish as they swam upstream in the Barwon River. The traps consist of a series of stone walls and channels that guide fish into shallow pools, making them easier to catch. These fish traps are significant not only for their age but also for their cultural importance to the Ngemba and Murrawarri peoples. They demonstrate sophisticated knowledge of local ecology and sustainable fishing practices, reflecting the deep connection between Indigenous Australians and their environment.
