Sarah Harris joins Ten's morning show Sarah Harris has been named as the third host of Network Ten's new morning show Studio 10. JOURNALIST Sarah Harris has been named the third host of Network Ten's new morning show Studio 10. Harris is jumping ship from the Nine Network to join Ita Buttrose and media identity Joe Hildebrand on the live panel show. A fourth host will be revealed soon, the network said in a statement on Saturday. In recent years, Harris has presented and reported for Nine's Today, Weekend Today and Mornings programs, and Nine News Australia. She has also worked for the Seven Network and Prime Media Group during her 16-year career in journalism. "Sarah was always my first choice for the important role of bus driver," Studio 10 Executive Producer Rob McKnight said. Harris said she jumped at the chance to join the show. Ita is an industry icon and Joe's a media maverick. Together they are television dynamite," she said in a statement. And as a journo, I jumped - actually make that pole-vaulted - at the chance to work with them. Studio 10 will debut later in 2013.
