Show society president Harold Sharman has already been impressed with the quality of cattle on display.

He and publicity officer Karen Barker said they are "incredibly proud" of the way the Valley community has come together after three years of drought, weeks of fires, and this week floods.

Mr Sharman spent six weeks fighting the fires as part of the Kangaroo Valley RFS.

"It's dear to my heart that this continues on," he said.

"And this afternoon I have the privilege of my only granddaughter coming to the show. It's an amazing feeling."

In the pavilion, judges are busy assessing baked goods, fruit, veggies, flower displays and craft.

Baked goods judge Laurel Oke said the three most important factors were texture, flavour and presentation.

"If the schedule says it's a peach blossom cake, I know you cream your butter and sugar with no egg yolks, and cream the whites separately," she said.

"You can tell by the way it comes out of the oven if that's been done in the correct order."

The secret to being a great baker - and judge - without packing on the kilos is to have people happy to eat your produce.

"It's why when most women's children leave home they stop baking," steward Anne Walder said.

Steward Les Adams is a grower and has been involved in the show for 30-odd years.

He said he was blown away by the amount and quality of fresh fruit and veg that had been submitted.

"It's amazing, it's absolutely amazing," he said.

"Considering the year we've had, I was expecting about half the quality and the quantity that we've got. I'm really impressed. I think we may have collected some exhibitors from other shows that aren't running this year - I find it outstanding."
