Organiser Yolande Grosser and daughters Yasinta and Katiana ran a fundraising barbecue outside Horsham Woolworths on Saturday last week.

It was one of the coldest days of the year.

Temperatures ranged from -3.4 to 12 degrees, but Mrs Grosser said the girls' hearts were warmed by people's generosity.

"People have been really generous," she said.

The barbecue raised about $300.

Mrs Grosser said the money would go towards catering for the event.

"To take the pressure off our Salvation Army barbecue, the Horsham Shed Night men have offered to cook a second barbecue," she said.

"This, along with a second popcorn machine and fruit kebabs, should keep the hunger pangs at bay."

Organisers will also pack 800 more fun bags than last year, bringing the total to 1800.

"We ran out last year, which made us sad," Mrs Grosser said.

"We will be packing the bags with lollies, colouring pictures, stickers and a devotional booklet for boys and girls written by me it's my first book.

"The book has been illustrated by the year sevens at Holy Trinity Lutheran School."

Christian children's musician Sean W. Smith will perform for a second year.

This year, fellow Christian children's musician Chris Jaensch will share the stage.

With new rides and attractions booked, Mrs Grosser said the event's cost would exceed $20,000.

She said Operation 19:14 was made possible with the generous support of Wimmera people, churches and businesses.

The event is at Sawyer Park from noon on August 31.

Mrs Grosser said rides finished at 3pm to coincide with the start of the stage performances.

Prizes such as an Apple iPad Air will be awarded following the acts.

People can attend the festivities free of charge.
