[11][12][13] (Ages stated are at start of contest) The final thirteen took part in their first runway challenge in front of a crowd of 400 people, and had to model designs from Alex Perry's S/S16 collection.

The models competed in groups for a challenge in which they had to create a social media video for Colgate Optic White, with the best performer being chosen as an ambassador for the brand.

The contestants later arrived at Randwick Racecourse, where they were introduced to Australian model Elle Macpherson, and took part in an equestrian inspired photo shoot with a racehorse.

The remaining eleven contestants were challenged to walk in a presentation for Swarovski as a part of Mercedes-Benz Fashion Week to win the opportunity of being featured in the brands upcoming Crystaldust campaign, and were later coached by former Australia's Next Top Model contestants Amanda Ware, Cassi Van Den Dungen, and Simone Holtznagel in preparation for a latex photo shoot in groups photographed by Jez Smith.

After a screen test challenge mentored by model-actress Gemma Ward, the models took part in a photo shoot session at Cradle Mountain in Tasmania.

The final eight models were challenged to walk in a runway show over a pool, where they had to dive underwater and pose in a bid to be granted immunity from the upcoming double elimination.

After arriving, the models took on a casting challenge for Trussardi, for which the winner was awarded double the amount of time in front of the camera for the upcoming photo shoot.

After the judges reviewed the covers from the final photo shoot of the series, Aleyna was crowned as the tenth winner of Australia's Next Top Model.
