Killain is owned and operated by Richard and Susie Duddy, along with their two sons, Benjamin and Thomas. The stud is located in the famed Goonoo Goonoo area in Tamworth NSW.

From the very start, the stud was set up as a sister stud to the world famous Schaff Angus Valley, located in North Dakota USA, which means that Killain Angus is based on this elite genetic line. From the beginning, Killain Angus was established with the commercial cattleman as it's number 1 priority.

We have been a major supplier to Australia’s premier Angus feedlot, Rangers Valley, in Northern NSW, and Woolworths for many years and therefore fully understand the requirements for the commercial beef industry.

Since the establishment of Killain Angus in 2013, we have imported and utilised embryos and semen from the finest SAV donors and sires in our breeding program.

In 2025, we purchased 2,500 acres on King Island where we run a 1,000 Angus commercial cow operation supplying Greenhams, Tasmania. All bulls are Killain Angus Stud bulls bred in Tamworth and shipped to King Island. This will enable us to benchmark our genetics and follow them right though to record actual carcase data.
