During the course of each episode, four acts are presented by their corresponding comedian. Each comedian has a brief banter with host Reucassel before and after each skit. At the end of each episode the studio audience is asked to decide which act had the biggest 'Balls of Steel' by voting with their mobile phones. Series one initially started with ten different comedians and their corresponding acts.
Neg Dupree reprises his role with the Urban Sports segment from the original UK version. The series also has Australian local versions of "The Annoying Devil" and "Bunny Boiler". It also featured many exclusive acts only seen on this version of the show though some take in similar ideas and formats from many previous acts from the UK version. In addition, a studio based segment called "Show Us Your Balls" was created, where people in the audience are asked to participate and will be competing among the other comedians of the show. This segment is presented by host Reucassel. Series two sees some changes to the line up of comedians and their acts. Katia Taylor will not return to reprise her role as "Nude Girl" but instead will be replaced by the "Nude Twins". Other comedians who didn't return were Janis McGavin and Rachael Coopes.
John Burgess replaces
James Kerley as "The Game Show Host from Hell". New comedians and acts for this series includes
Olivia Lee from the original UK series, "The Misfits Stunt Crew" and
Imaan Hadchiti as "Short Tempered". Returning acts include the "Bunny Boiler", "Very Foreign Correspondent", "Neg's Urban Sports Down Under", and "Just Come Out". ==Performers and acts==
