Sand Sculpting Australia is an exhibition that is held in conjunction with the Moomba Waterfest in Melbourne from 5th March to 21st March in Birrarung Marr. These are not the sandcastles you build on the beach. They are truly works of art made by talented sculptors from around the world. Pretty amazing and i'll just let the photos speak for themselves. Better yet, if you're in Melbourne, go and have a look for yourself. Proceeds from the entrance fee go to Vision Australia Foundation in aid for the blind and vision impaired. I've also uploaded a few other photos of the Moomba Carnival.
