The buyer of the top-priced heifer in the Ayrshire sale at International Dairy Week on Tuesday first spotted the animal when he judged it in a country show last year.
Steven Eagles, from the Eagles Partnership, Gooloogong, NSW, placed Boldview Demp-Star as champion in the Murray Bridge, South Australia, all breeds heifer show in July.
"I have liked her since then," he said.
Mr Eagles paid $4800 for the heifer offered by Boldview Farms, Jervois, SA.
The Eagles Partnership milks 280 cows off irrigated pastures, with the herd comprising two-thirds Holsteins and one-third Ayrshires.
Mr Eagles said his grandfather started breeding Ayrshires when he returned from World War II.
"So it's in my blood," he said.
"They perform well in the herd."
The second top-priced lot was another offering from Boldview Farms, which sold for $4500 to CM Fahey, Toolijooa, NSW.
In all nine of the 11 lots in the sale sold for an average of $2878, including an embryo package that sold for $4000.
