Hi-5 Members

Hi-5 is an Australian children's musical group formed in 1998 which is associated with the children's television series of the same name.

Origins of the group
In 1998, television producer Helena Harris, creator of Bananas in Pyjamas, decided to make a new show called "Hi-5" when her two children outgrew Bananas in Pyjamas. She and co-producer Posie Graeme-Evans decided that the new show would be aimed at children of all ages, include educational trends as fun and games, and feature music and movement that would attract children's attention.

The auditions for the hosts and the eventual members that would make up the group were held in June 1998, with the first program broadcast in April 1999. Since then, the group has won five consecutive ARIA awards for "Best Children's Album" (from 2000-2004), won three Australian Logie Awards (the Australian Awards for television performance and production recognition) for "Most Outstanding Children's Program" in 2000, 2001 (tied with Round the Twist) and 2004 (for "Most Outstanding Children's Preschool Program").
