This week the queen of the catwalk Naomi gives the girls a lesson on how to walk, before setting them a ‘quick change’ challenge in preparation for the upcoming campaign. The three teams face their first live catwalk as they put on a fashion show at the Sydney Opera House for one of Australia’s finest couture and wedding dress designers, Steven Khalil. The big twist is that they have 50 steps to contend with before hitting the catwalk. The drama-o-meter hits a high note after tonight’s shock elimination.
