A nomadic people with a warlike reputation, there were many reports of attacks on early explorers when their territory was invaded. The Wiradjuri had semi permanent camping spots on the Boorowa and Lachlan Rivers. There may have been several thousand of the Lachlan tribal group at first settlement, but surveys showed only 300 were left in 1851. The last remants of local tribes were herded on to government reserves (Rye Park, and Edgerton, near Yass.) The last member of the Lachlan tribe was thought to have died in 1926.
The name Burrowa, by which the region was once known, and Boorowa were said to be aboriginal words for native birds – long since gone.
It is not known who the first European explorers were to have discovered the Boorowa River and its surrounding plains.
Hamilton Hume, in conjunction with brother in law George Barber, brother John and neighbour William Broughton, undertook a private and secret journey of exploration to seek out land suitable for settlement in journey in 1821. Roger Corcoran was the first European to take up residence in the area, claiming land on Corcoran’s Creek.
