At the time, Cassi was just 16 years old.
Just one day after losing the popular reality competition to fellow contestant Tahnee Atkinson, Cassi was immediately offered modelling contracts from New York City’s Elite Model Management and Priscilla’s Model Management.
Initially, Cassi turned down the contracts, controversially choosing instead to stay in Sunbury with her partner, Brad Saul.
But in the years that followed, her career skyrocketed, seeing her walking at Paris Fashion Week and appearing in campaigns for Australian designers such as Alex Perry and Zimmermann.
A decade on from Cassi’s time on Australia’s Next Top Model, this is what her life looks like now.
She's still modelling.
In the years after ANTM ended, Cassi Van Den Dungen made her international debut walking for Calvin Klien in New York and Miu Miu in Paris.
She has also appeared in editorials in a number of magazines including Cleo magazine, Elle Australia, Oyster magazine, Australian Vogue and Russh magazine.
In 2014, however, Cassi's appearance on the Alex Perry runway during Sydney's Mercedes Benz Fashion Week led to a media storm when the model's frame was discussed on Australian breakfast television.
At the time, then-Marie Claire editor-in-chief Jackie Frank claimed that Cassi was too slim, leading designer Alex Perry to respond to the claims.
“That’s not the image that I think is a good one to put forward. It’s certainly not what I’ve presented my brand about," he said at the time.
Speaking to news.com.au last year, Cassi shared what it was like being scrutinised in the public eye.
