The Australian singer, who was announced as the new host of the revamped Young Talent Time last year, said that he has strengths and weaknesses as a TV host.
Mills told National Features: "I think my strength is connecting with people from all walks of life and all age groups to deal with kids from eight to 16 and an audience that will range from eight to 80.
"One of my weaknesses is my lack of experience, but I've been working really hard with Ten and the crew to get me up to speed. I know I've still got lots to learn."
Mills said that Australia was ready for a show like Young Talent Time because "the whole world is screaming out for more positivity".
Mills also said that he loves working with singer Tina Arena on the show, saying: "Tina's like a mother hen. Some people have said to me that she comes across a bit stern on the TV.
"I think maybe she's just nervous on camera a bit. Off-camera she couldn't be more nurturing and lovely to the kids."
Mills is currently rumoured to be dating former Neighbours actress Stephanie McIntosh.
