ITEMS from some of Australia’s favourite celebrities and personalities are ‘under the hammer’ in a unique mobile app auction to raise money for charities.

The inaugural Celebrity Charity Garage Sale runs until August 8 and fans can bid to own items donated by Jimmy Barnes, Leo Sayer, Matt Shirvington, Kylie Kwong and Anna Bligh.

All proceeds of each item sold will go directly to the chosen charity of each celebrity, which include Cure for Brain Cancer, Souths Cares, Bear Cottage, Healthy Harold, Prostate Cancer Foundation of Australia, Randwick Children’s Hospital and Barnardos.

Items have been listed with a starting bid through a new location-based buyer/seller app called Locl. The highest bidder at the end of the sale becomes the proud owner of the pre-loved item.

Locl cofounder Nir Davidson said the auction was a unique way to promote the free iPhone app, which allowed people to buy or sell items according to their location with no seller fees.

“It’s such a different way to buy and sell and we are seeing thousands of new users come on board. It’s location-based app that allows you to see what amazing items are for sale within metres or kilometres around you … the app is smart so you can even add a wish list and it will send you a push notification to advise when the item is listed for sale.

As no fees applied to sell goods, Mr Davidson said the app’s simplicity was “definitely shaking things up a bit” in online buying and selling.

“When we thinking of a way to promote it we thought why not raise money for charity and get some celebrities on board and have a celebrity garage sale,” Mr Davidson said.

“We are simple rapt that so many items have been put forward and that people can bid to own some unique items and help raise money for some worthwhile causes. It’s a fun way to promote the app.”

While 80 per cent of users are in Australia, the app is in use in Asia, the UK and the US.

“Every item gathering dust and not being used is a chance to make a difference to the lives of somebody else,” Jimmy Barnes said. “No matter who you are, this is the chance for all Australians to pledge their support to a worthwhile causes and secure a one-of-a-kind item in return. I’m proud to be highlighting the work of the Children’s Hospital at Westmead with my stage worn jeans… with real rock ‘n’ roll holes!”

Other celebrities donating items include Leo Sayer selling an outfit, former Queensland premier Anna Bligh has donated her guitar signed by performers at the 2013 Rock Opera, radio presenter Jonesy a brake disc from his bike and Matt Shirvington a Tom Tom watch.
