A crowd of more than 200 turned up for the auction, conducted by Brian Muller. The new four-bedroom home was a labour of love by the Shoalhaven community.

The sale price of $430,000 was good news for Variety, the Children's Charity, which will receive more than $200,000 from the sale to help local sick, disadvantaged and special-needs kids.

More than 80 local tradespeople and building suppliers, led by Shoalhaven's GJ Gardner Homes, brought the home to fruition on land that was given to Variety for a generously discounted price by the local Macdonald family.

"We had been looking for a place for ages and then this came up, which was absolutely perfect," Ms Irwin said.

"It was brand new and beautiful and ticked all of our boxes. We are really happy with the price we paid and knowing that the money we've spent will also go to Variety to help kids in need has made buying our first home all the more special."

Among the people Variety has assisted is 10-year-old Lili Smith, from Albion Park Rail.

Lili lives with the rare brain disorder agenesis of the corpus callosum, epilepsy and the neurological disorder microcephaly and uses a wheelchair.

Variety assisted Lili and her family by providing them with financial support to go towards modifying the family car to hold her wheelchair.
