NSW breeders Ian and Donna Gilmore and sons Brayden and Lachlan scooped the pool in the Australian Whites judging, including the third consecutive champion ram title.
Their Baringa stud from Oberon introduced the breed to the Royal Adelaide Show in 2016 and have returned every year since to putting their sheep in front of interested onlookers.
Judge and respected White Suffolk breeder Andrew Donnan, Woomelang, Vic said there may have only been a small number of animals, with about 12 head, but they were of a high standard, especially his champions.
"The ones I picked at the top were more correct in walking and balanced and were a bit longer," he said.
Brayden Gilmore said it was "huge" for them to win every class and hear the positive comments from Mr Donnan about the muscling and structure of the sheep which they have worked particularly hard on.
He said the champion ram, a June 2018 drop would be retained in stud.
"It's a very good skinned sheep, it hasn't been shorn before so it has the hair type that we are chasing and has really balanced EBV's which is something we see a future to breed with," he said.
On the ewes it was an April 2018 drop which had been used in several embryo transfer programs which came up trumps.
The same ewe that impressed Mr Donnan also won the tricoloured ewe ribbon at the 2019 Sydney Royal Easter Show.
"The meat carries through from the front to the back without being too broad at the front," he said.
Brayden sees a big future for the breed, especially for those producers those looking for a "self replacing, easy care" flock.
"The Australian White (breed) is very low maintenance with no shearing and no crutching and we are no longer tailing our lambs which is something I think in the future is going to be a real bonus," he said.
"If we can strike a decent season over here (in SA) in the north that will be a huge turning point for us."
Baringa will hold its second annual sale in SA in October at Jamestown with Seriston stud, Avenue Range.
