The couple want to raise awareness and money for the survivors of the catastrophe which claimed the lives of 200,000 people on 26 December 2004.
Sharon says, "We've had a rough year but we come home to the safety of our home every night. These people lost everything."
An insider at British network ITV1 adds, "Sharon and Ozzy were so involved in raising funds for the tsunami. This is their chance to go back and see how things have improved."
