100% is an unsold Australian pilot/version of the popular British game show hosted (voiceover only) by Shaun Cosgrove, produced by Grundy Television and it was taped for Nine Network on 16 September 1999.
The rules of the game were the same one as the British one, except there were a few differences:
- It cost "$100" instead of "£100" just like in the US version.
- Each correct answer cost from 0% to 100%.
- The theme for the Australian pilot was the same one used on the Australian version of Family Feud from 1977-1984 (in turn, which was a remix of the 1976 I've Got a Secret and Second Chance theme songs).
