First-time competition organiser Cameron Thompson, of Bracknell, said more than $3000 had already been sourced for the junior Jersey competition section.

The show will not only also have sections for Holsteins and Ayreshires, but will have an all-breed finals during the event.

"I would imagine the other two breeds, especially Holsteins, would have at least $3000 in sponsorship as well," Mr Thompson said.

"That's a lot of sponsorship between 25 or 30 kids who will be there."

He said a change of venue for this year meant money and effort would be saved by competition organisers.

"We usually hold them at the Devonport Showgrounds," Mr Thompson said.

"One of our exhibitors, the Young family at Datumvale Holsteins, have just built a brand new shed — they're doing a whole indoor arena for us, they're including wood shavings, a wash bay and everything for us.

"They have kids involved, which makes it a bit more friendly for us and cuts costs."

Junior judging will also be part of the show, where entrants judge five animals and give their reasonings for their score.

The juniors will be assessed by guest judge Cameron Yarnold of New South Wales' Arralik Holsteins stud.

"He'll comment on their reasonings and then give his comments and explain why," Mr Thompson said.

"They can learn off that, which will be on Saturday night."

Show organisers also include Shanae Perkins, on Holsteins, and Katie Haberle, with Ayreshires.
