The Celebrity series, held once a year, was especially popular. It was hosted by Fiona MacDonald and Billy J Smith, and featured teams made up from local sports clubs and community groups competing for cash prizes. The show followed an identical format to the 1970s show Almost Anything Goes and was loud, chaotic and colourful. It's a Knockout (1985–87) was a hugely popular show on Australian television in the 1980s.
