Welcome to Thornby.

Born to farm.

With deep roots in Australian agriculture, Thornby combines over 150 years of farming heritage with modern innovation to produce premium lamb.

We are leaders in ethical practices, farming for the future, and the quality of our lambs, feeding the world with care and expertise.

Our business name “Thornby” comes from the name of our historic farming property at Sanderston on South Australia’s Murray Plains. Our family, the McGorman’s, have been farming this property for over 120 years with current fourth generation family Alex and Fiona and their three boys Flynn, Angus and Oscar continuing this family tradition with the help of a great team.

Operations on Thornby has increased in scale to today annually cropping 13,000 acres of broadacre cereal grains and hay and finish over 130,000 lambs through our AusMeat accredited lamb feedlot. Thornby proudly employs a team of over 25 staff members and is passionate about supporting and enabling future agriculture leaders.

Today we also dabble in firewood processing, selling quality locally sourced South Australian mixed gum to the public and select local businesses. This move has enabled us to employ more staff and spread the risk across different baskets so to speak!
