She quickly gained the favor of the judges, notably Alex Perry, though some concerns were raised early on in the competition due to her low body mass index.

In a live finale broadcast on 5 June 2007, Burdeu was named winner of the cycle based on votes cast by the judges and by Australia's Next Top Model viewers.

In the finale of the same cycle, Burdeu announced the winner of the series in a live broadcast from Paris, where she was working at the time.
