Tattykeel is the Birth Place of the Australian White Sheep Breed.
The Australian White was developed to be a self-replacing, haired, meat sheep that required minimal maintenance. The four breeds of sheep that were selected to develop the breed were chosen for specific traits they could bring to the breed. These breeds were the Poll Dorset, Texel, White Dorper and Van Rooy.
Graham, his brother Martin, and his sons James and Ross controlled the development of the breed through rigorous selection and breeding programs on the Tattykeel properties in Black Springs NSW.
