Farmers Fraser and Steven Laird, from a sheep, beef, dairy and cropping farm at Fordell, are helping organise the event.
They are hoping it will interest city people who have little experience with rural life.
The people who attend won't be sitting in the grandstand watching, they'll be down among the action and able to compete in traditional sports such as sack racing and gumboot throwing.
David Cone will be on hand to race his famous Baa Black sheep five times during the afternoon.
Contractor Steve McDonald will do some shearing and dogs will pilot groups of wily sheep down the hill from the clock tower and into pens on the game oval.
The afternoon will be especially good for families and international guests, the young farmers said.
They are trying to promote the rural lifestyle, believing that many town people don't get the opportunity to see activities such as dog trialing.
Sponsorship is being sought for prizes and expenses, and any money raised goes to the Young Farmers' Club.
