The company's headquarters, and home to the Litchfield family, is located at Hazeldean near Cooma in the Monaro district of south-eastern New South Wales.

Hazeldean Merinos has grown from its establishment in 1865 by James Litchfield, to be one of the largest, most progressive and influential flocks in Australia. It was built on Rambouillet bloodlines with occasional Riverina Peppin infusions, and today, around 14,000 stud ewes are mated.

Ram breeding and growing out centres are located at Hazeldean, Cooma and Rosevale, Hay in New South Wales.

These strategically located properties ensure sheep are bred and selected in the same environment where commercial woolgrowers operate or know how animals perform on their own property. It ensures there are no surprises when rams arrive home and they are ready to work without an extended settling in period. Because of this geographical spread, Hazeldean rams are well acclimatized and adapted to most areas of Australia.

With a total flock size of over 45,000 sheep Hazeldean Merinos have one of the largest individual gene pools in Australia, making intense selection pressure possible in the breeding programme.

For over 45 years selection has been based on measured fleece value gathered from each ram and ewe produced. This is the same information that establishes the price woolgrowers get paid when they sell their wool and is heritable and repeatable.

Hazeldean Merinos are accredited free of Brucellosis and monitored negative stage 3 (MN3) for Ovine Johnes disease.

Hazeldean's business also includes commercial flocks and herds as well as the production of cereal grains however its main interest is the production of superior seedstock. In both cattle and sheep it ranks among the country's largest suppliers and when viewed as a whole, has a major influence on the genetic makeup and progress of Australia's extensive livestock industries.
