Jez Smith returned as part of the judging panel for the first time since the third season, and Jonathan Pease was replaced by fashion icon Josh Flinn, due to the former's work conflicts.

In contrast to the previous three seasons, the viewer vote entirely determined the winner and placements of each contestant during the live finale.

At the photo shoot, the contestants were styled in 1950s inspired clothing from the TV series, Mad Men, and a mass-elimination at panel saw five of them eliminated from the competition.

At the challenge, the girls were cast in a show for Megan Gale's swimsuit collection with a liminted number of spots, and the winner received a 5-night stay at a luxury resort in Queensland for her and a friend.

Back in Sydney, the contestants had a photo shoot for Impulse in which they had to embody different fragrances, with the best performer being given the opportunity to front a national ad campaign.

The remaining contestants received a lesson on their best angles and expressions from judge Jez Smith, and later shot for a Telstra television advertisement with a limited number of spots.

They were later taken to The Metro Theatre to walk in an underwear show for Bonds lingerie in order to score an ad campaign for the brand.

At the crack of dawn, the contestants were driven to Thredbo for a photo shoot in the Snowy Mountains where they had to pose with vintage lingerie and animal pelts in the freezing temperatures.

The models received runway practice through the streets of Sydney with mentor Josh Flinn, while they were secretly being watched by Anneliese Seubert and Alex Perry.

The remaining models participated in a couture fashion show for the Sony Foundation in front of the judges, and after a high-pressure fitting under the scrutiny of Harper's Bazaar editor Edwina McCann, they prepared for a grueling two-day photo shoot session in which they had their winning editorials and covers taken.

In a shocking turn of events, host Sarah Murdoch announced that the final results were fed to her wrong, and that the actual winner of the competition was Amanda.

In the days following the airing of the live final, the show was accused of feigning the botched announcement as a publicity stunt.
