All grown up! Bec Hewitt embraces her daughter Mia, 18, before former Home and Away star heads off on an overseas adventure with her youngest daughter Ava, 13

Bec Hewitt was seen saying goodbye to her eldest daughter Mia at Sydney airport on Sunday as she traveled with her youngest Ava.

The former Home and Away star, 40, was all smiles as she hugged the 18-year-old who drove her famous mother and sister, 13, to the departure area.

Mia, who looked chic in a simple black T-shirt, white shorts and brown boots, also gave her sister a loving hug as they said goodbye.

Ava seemed excited to fly abroad for an adventure with her mother.

The Nickelodeon star hoisted a backpack over her shoulder and wore a pastel pink T-shirt and baggy gray sweatpants over a pair of Nike shoes.

The rising star looked every bit like her actress mother, pulling her brown locks back into a half-updo.

She waved goodbye to her older sister one last time before wheeling her suitcase through the airport with her mother.

Meanwhile, Bec adopted a much more monochrome look, opting for an all-black outfit with a basic T-shirt, sweatpants and sneakers.

The 15-year-old was given a wildcard for this year’s Australian Open Junior Championships, although he was beaten by Alexander Razeghi.

Meanwhile, his older sister Mia has shown more interest in fashion and modelling, recently receiving a Diploma of Branded Fashion Design.

She has also been spotted at exclusive fashion shows with her mother Bec, with the pair attending events together during Paris Fashion Week in the past.

The youngest of the brood Ava has more than kept up with her siblings, dabbles in dancing, acting, modeling and gymnastics, and is now the Nick News Host.
