Baringa stud, Oberon, took out both champion White Suffolk ram and ewe at the Sydney Royal.
White Suffolks arre celebrating the breed's 30th year and were feature breed.
White Suffolk Judge, Andrew Frick, Gypsum Hill White Suffolk stud, Padthaway, South Australia, said the champion milk tooth shorn ram, under 12 months of age, "ticked all of the boxes" and stood out for his confirmation.
"He was an active sheep, with enough muscle and was long and free moving," he said.
"The reserve champion was a tremendous ram, but it just lacked that little bit of style the Baringa ram displayed."
The champion ram was from the first drop of its sire, a ram purchased from Detpa Grove, Nhill, Victoria, at their 2013 sale for $16,000.
It was the first time Baringa's Gilmore family had showed the ram, which would go on to lead their show team for the remainder of the year.
The reserve champion ram, which Mr Frick said was an extremely muscly young exhibit, was displayed by Merton stud, Mudgee.
Stud principal Bruce Stanford said the milk tooth shorn ram, under 12 months of age, had exceptional carcass quality and muscling.
Weighing 96 kilograms and sired by a Kurraview ram, it was also the reserve champion White Suffolk at the Canberra show this year.
The champion White Suffolk ewe, also bred by Baringa, took out the title for supreme prime lamb ewe at last year's Sydney Royal.
The two tooth, shorn ewe's sire also had notable show success, winning champion ram of the show at Sydney Royal last year as well as the champion ram at the NSW State Sheep Show, Dubbo.
The ewe is in lamb to Premier Optimum, which was Baringa's top priced ram at their sale last year and sold for $16,000.
Although the decision was difficult, Mr Frick said he eventually chose the older ewe for her confirmation.
"It had all the commercial attributes I was looking for with the package of confirmation and carrying herself so well," he said.
"There was tough competition from the reserve champion ewe, who was a very meaty type."
The reserve champion milk tooth, shorn ewe, under 12 months of age, was displayed by Merton stud.
Mr Stanford said the ewe had great success at the Canberra show this year, taking out Supreme short wool ewe and champion White Suffolk ewe.
Mr Frick said producers have bred sheep that suit the requirements of the prime lamb industry.
"The White Suffolk have great flesh and muscling and are free moving sheep," he said.
"They're also still maintaining their clean points."
Mr Frick said producers should be complimented on tuning their genetics to suit their own particular market.
He also commended exhibitors for choosing to promote quality in the breed, rather than the biggest sheep.
Although Mr Frick said exhibitor numbers weren't overwhelming at the show, the quality of the lineup was fantastic, which made his job difficult.
"I try to focus on the positives when judging," he said.
"But a lot of the time it came down to comparing one sheep's weakness with the other's."
