Heritage listings Brewarrina has a number of heritage-listed sites, including: Brewarrina Aboriginal Fish Traps The Old Mission Road: Brewarrina Aboriginal Mission Site Ancient Aboriginal fish traps Brewarrina's most significant feature is its Aboriginal fish traps. Known in the local Aboriginal language as Baiame's Ngunnhu. It is believed that Ngemba, Wonkamurra, Wailwan and Gomolaroi people have shared and maintained the traps for thousands of years. The age of the fish traps is currently unknown, but they may be the oldest human construction in the world. Locals claim that the traps are at least 40,000 years old and thus the oldest surviving human-made structure in the world. Consisting of river stones arranged to form small channels, the traps direct fish into small areas from which they are readily plucked. The traps form a complex net of linked weirs and ponds along 500m of the river. They operate at varying water heights and can be altered to suit seasonal changes. People use their expert knowledge of fish species and the environment to maximise their catch. Brewarrina Ngemba Billabong has been declared a World Conservation Union (IUCN) Category V and VI protected area. It was declared an Indigenous Protected Area in November 2010.
