Despite a jump in entries from 94 last year to 116 this year within the Illawarra competition, Glenbrook, Murray Bridge, took all but one two of the accolades on offer.
Glenbrook Dainty 14, Glenbrook, Murray Bridge won the first place in five year-old in milk before taking out the senior champion exhibit and then the supreme champion.
Judge Paul Harrison, Northumberland, UK, said the cow was awesome and beautifully balanced.
"The cow had a huge amount of dairying character," he said.
"It was a tremendous cow which has beautiful venation right throughout the udder and it was a cow that tracked really well."
Glenbrook's Ian Mueller, Murray Bridge said apart from the Gold Rush years, World War Two and the two COVID years, his family has been represented at Adelaide showing Illawarra's.
"It's basically in my blood," he said.
"This particularly cow, I've had ear marked out for a few years to get her in the right form to bring her out.
"And I wanted to have a mother here this year but from carving she just hasn't got herself up and going and couldn't come.
"But to me this cow has got the framework that I really admire and a beautiful udder."
The intermediate champion came from the cow 2.5 year-old in milk class where Glenbrook Nancy 63, Emily Mueller, Murray Bridge, won first place.
Mr Harrison said the cow was a "real modern day cow" that they like in the UK.
"She tracked really well on those legs and has a fantastic mammary system," he said.
The reserve intermediate champion was Glenbrook Carnation which was second in the same class as the champion.
The juvenile champion was the first place exhibit from the heifer class where Glenbrook Harmony took out first place, while Glenbrook Thorn 50 from the 18-months-old class won reserve juvenile.
The most successful exhibitor of the competition named Glenbrook for the accolade.
