The nation's number one group buying site, Groupon Australia, and charity The Smith Family, will be spreading festive joy around Sydney by rewarding Christmas spirit with Christmas kisses.

Sydney's very own winter wonderland will be recreated at Customs House where male and female models dressed in festive costumes, along with Santa Claus and his reindeers, will be spreading Christmas spirit to Sydneysiders.

For a small donation of $5 to The Smith Family Christmas Appeal, the public can get a Christmas kiss from the Groupon models and a picture with Santa Claus in his very own sleigh. The official Groupon Christmas Spirit voucher is available from Friday 14th December where the public can purchase their kiss via the website.

The Groupon winter wonderland will be open to the general public from 11.30am with every $5 donation in exchange for a Christmas kiss going to The Smith Family.
