More than 300 pieces of designer clothing and accessories will be available to purchase online including pieces from Alex Perry, Toni Maticevski, Sass and Bide, and Acne.
In an official statement to WHO, the 34-year-old beauty opened up about the latest charitable project.
"I have always been a huge supporter of the Salvos, it's a privilege to partner with them again to help families in need," she began.
"This sale is really fun way to make a difference. Not only can you pick up some designer clothes for a great price, but you can feel good knowing your money is going towards a good cause"
"The Salvos do great work in our community. I really hope this small gesture of donating my wardrobe will make a big difference."
All of the items donated by former Australia's Next Top Model host can be purchased online from 8 pm Saturday 14th July till 8 pm Thursday 19th July here.
