‘Codenwarra’ is located just outside the of town of Emerald, Queensland, and was first purchased by the McCosker family in 1929. For almost seven decades, the family raised sheep, bred Hereford cattle, and grew crops on the land.
In 1997 John and Robin McCosker became pioneers of the Australian Wagyu industry when they bought fullblood bulls and began the Codenwarra Wagyu herd. In 2000 John and Robin purchased fullblood embryos and Codenwarra Stud was established.
Michael and Susan purchased their original property ‘Marathon’ in 1996 and have grown award winning cotton crops there ever since. In 2016 they bought neighbouring property ‘Lake Nash’ and turned the existing abattoir infrastructure into a backgrounding and artificial insemination facility for the growing Marathon Wagyu herd.
In 2022 the Codenwarra property and Wagyu stud was purchased by Michael and Susan who then amalgamated it with their existing stud, Marathon Wagyu.
