The Voice Australia 2013 is all set for its grand finale in a week's time. The four grand finalists - Harrison Craig, Celia Pavey, Danny Ross and Luke Kennedy - are already winners at this point. But only one will hold the title alongside Karise Eden in the show's history. Harry topped the iTunes chart following his performance Monday night. Is that a sign of a big win at the finale?

Who will emerge the champ in The Voice Australia 2013? The one with the biggest following, as usual. Among the four, Harrison Craig, 18, and Celia Pavey, 19, are likely to have the biggest chunk of voters. Their age group works well for them, and the judges absolutely love them both. The songs they're given always bring out the best in them.

However, it appears everything's been decided at this point. Harrison Craig is going to win the whole thing, reckons many Twitter users. For one, Harry has topped the iTunes chart yet again. This time, his performance during Original Composition round on The Voice Monday night, "More than a Dream," is touching the Aussies' hearts.

Celia Pavey, on the other hand, has been holding her own. She has more following than Danny Ross, than Luke Kennedy. But the numbers are not likely to be enough. She's a mellow folksy singer who looks like the beautiful Sansa Stark of Game of Thrones. It may or may not work for the voters. But the original song she performed, "Candle in the Wind," has nothing to compete with "More than a Dream."

Harrison's speech impediment becomes key to his lead in The Voice. It certainly helps that he has been dishing solid numbers. But inspiring hundreds of thousands of viewers is a bigger thing. "More than a Dream" is his life's theme, and the new pop pick me up song in Australia.
