She's the daughter of fashion icon Christie Brinkley, who relocated to Australia earlier this year.
And on Saturday, Sailor Brinkley-Cook enjoyed a day at Sydney's Bondi Beach with boyfriend Ben Sosne.
The 20-year-old American model packed on the PDA with her beau, before revealing her figure in a high-cut blue swimsuit.

Sailor wrapped her arms around Ben and leaned in for a steamy kiss on the boardwalk.
The blonde Beauty sported a burnt orange polka dot wrap dress and white Converse sneakers.
She added a touch of bling in the form of hoop earrings, and her locks fell in waves around a blemish-free complexion.

Ben wore an unbuttoned black linen dress shirt, teal patterned board shorts and camouflage print sneakers.
His long locks flowed in the breeze and he concealed his gaze behind silver round-rimmed sunglasses.
The pair later made their way to a rocky ledge, where Sailor posed for photos.
