On 22 July 2010 Liaw was the first challenger awarded a place in the grand finale. On Sunday, 25 July 2010 he was announced the winner of MasterChef Australia, Season 2, defeating Callum Hann 89–82 for the title. His victory is still the most watched non-sporting television event in Australian history. Aside from his winner's book deal, Liaw is considering other business opportunities, including an izakaya restaurant with Tokyo-based Australian chef and friend Matthew Crabbe. On 17 September 2010 it was confirmed that Liaw and Crabbe would be joined by a third business partner, Nathan Smith.
