She is the daughter of model and fashion icon Christine Brinkley, who took her career Down Under earlier this year.
And Sailor Brinkley-Cook made her latest foray into the Aussie modelling world at the Australian Turf Club Autumn Fashion Lunch on Wednesday.
The 20-year-old glowed in a white sheer turtleneck shift dress as she posed with horses at Sydney’s Royal Randwick.
The American model emphasised the white-on-white look with a pair of elegant high heels as she basked in the Autumn sunshine.
Adding to the striking appearance, she partly braided her blonde tresses and allowed the other half to flow effortlessly off her shoulder.
She completed the look with a beaded headpiece and a gold and silver wrist watch.
The young starlet appeared at the event alongside television beauties, Abbey Gelmi, Carissa Walford and Kate Waterhouse.
Former Miss Universe Jesinta Franklin and Australian swimmer Cate Campbell completed the group of ambassadors for the Autumn Carnival of horse racing.
In an interview with Stellar on Sunday, Sailor reflected on growing up in the spotlight and the inner demons she’s battled along the way.
