Hi-5 were an Australian children's musical group formed in 1998 in association with the children's television series of the same name. Helena Harris and Posie Graeme-Evans created the television series for the Nine Network, which premiered in 1999. The group were made up of five performers who entertained and educated preschool children through music, movement and play. Kellie Crawford, Kathleen de Leon Jones, Nathan Foley, Tim Harding and Charli Robinson were the founding members. By the end of 2008, all of the original line-up had left, and the group's membership changed several more times after that. They collectively starred in several television series, released albums, and performed on worldwide tours. The television series features puppet characters Chatterbox and Jup Jup, who were included in the group's live stage shows.
