It's a Knockout (1985–87) was a hugely popular show on Australian television in the 1980s.

The show followed an identical format to the 1970s show Almost Anything Goes and was loud, chaotic and colourful.

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 Celebrity series, held once a year, was especially popular. Teams were made up of celebrities from Network Ten, radio personalities, athletes, sports stars and others from 4 states who competed against each other to win money for their chosen charities.

This clip from the fourth It's a Knockout Celebrity Special introduces the teams and their captains. The stars in this episode include Guy Pearce, Kylie Minogue and Tina Arena.

We then see the first challenge, which involves a team member dressed in a bee costume battling their way through an obstacle course, with very funny results.

This final It's a Knockout Celebrity Special was recorded on 15 August 1986, but not broadcast until the following year.
