Scott and Shelley Dunn live with their three children on the Merino breeding property, “Wallendibby”, Delegate, New South Wales, at the foothills of the Snowy Mountains. Scott manages “Wallendibby” for Sir Michael and Lady Sally Nairn who live in Scotland but visit Wallendibby for extended periods each year. The flock currently comprises about 7,000 sheep. In the last 3 seasons the Dunns Merinos have produced, on average, a fleece weight of 7.1 kilograms, a fibre diameter of 18.1 microns, 74 % yield and 113% lambs weaned.

The SRS® Breeding System
SRS® Merino sheep are the result of selecting for low primary fibre diameter and high density plus high length of wool fibres. The breeding system was developed by SRS® Chief Scientist and Breeding Consultant, Dr Jim Watts, a research veterinarian who specializes in skin and fleece biology. It is based on Moore’s pre-papilla cell hypothesis of follicle formation and fibre growth.
Record rainfall across Eastern Australia throughout spring and summer 2010-11 resulted in a boom season for graziers, but the lingering warm, wet conditions also proved the perfect environment for flystrike. But not all flocks were as affected with a group of Merino producers proving that it is possible to breed sheep that can survive in hot, humid conditions without regular chemical treatment, or mulesing.
