Grace, 15, from Towamba, took the Beef Cattle Young Judges state crown in a field of 19 finalists from groups across NSW.

She was the first winner for Group 6 in the 40 years the Beef Cattle Young Judges has been running.

The competition was run by the Royal Agricultural Society and NSW Agricultural Show Council.

Grace said she was left spellbound after the announcement.

"I was shocked, I wasn't expecting to win because there were so many good competitors and they all spoke so well," she said.

"I really tried to focus on walking out there, putting an honest opinion forward and saying what I believe in.

"To be honest, it hasn't really sunk in yet, I'm still quite awestruck."

With her win at Sydney Royal, Grace did Group 6 Far South Coast and Tablelands proud, as well as her parents Maryanne and Josh Burns, and grandparents John and Jenny Alcock.

The 19 competitors had to judge three groups of four cattle, being Speckle Park bulls, Brahman bulls and Murray Grey heifers.

After they submitted their placings, the top 10 were selected to speak on the Speckle Park bulls to the crowd and overjudge.

Grace placed all three groups of cattle in the right order.

The overjudge, Rob Sinnamon, was very impressed with competitors and especially the top five place getters.

"In my opinion, youth is the future of our industry, we need these young people and it has been great to see the level of enthusiasm and interest," he said.

Grace qualified for the state final by competing in and winning the Group 6 finals of the Beef Cattle Young Judging at Nimmitabel Mini Show in 2020.

Grace has grown up on her families' farms - first Weroona, Bobundra, now Elmgrove, Towamba, and has a congenial way with all animals.

She attends Yanco Agricultural High School and is a member of its show team.

Grace will now represent NSW at the national finals at the Royal Queensland Show (the Ekka) in August.
