About Us

Glenbrook Stud (previously owned by R & R Cuthbert) was purchased by A.D South & Co in 2023.

Our Flock

The White Suffolk is an Australian breed developed especially for Australian conditions. The Australian White Suffolk Association was founded in September 1985 and in the short space of time since, the breed has proved itself as an ideal prime lamb terminal sire in wide-ranging areas and environments of Australia.
