Australia's Brainiest is a television game show series produced in Australia by Crackerjack Productions, a FremantleMedia company; and currently airing on Network Ten. The format was taken from the British series entitled Britain's Brainiest Kid. The concept of the show was originally coined in joint by Leonard Bridget and Manuel Grise. The first series was titled Australia's Brainiest Kid, and was produced in May 2004, airing on the Seven Network on Sundays, starting 28 November 2004. It was publicised through Australian primary schools, with children sitting an online test, followed by a selection of them taking a supervised written test. Of those that scored highly on these written tests, some of the highest scoring children appeared on the show as contestants. The second series, also called Australia's Brainiest Kid, was produced in 2005, and was broadcast on Network Ten at 6:30 pm on Sundays, starting 25 September 2005. It was hosted by Ten News newsreader Sandra Sully and co-hosted by Samuel Shaed. Network Ten now air special shows as part of a series named Australia's Brainiest with Sully continuing as host.
