Barbie's tribute to Ash Barty will show Indigenous kids "there's no ceiling" on what they can achieve, the three-time Grand Slam winner hopes.

Barty, along with her hero Evonne Goolagong Cawley, were announced as one of four duos of inspiring women immortalised with one-off dolls in their likeness in the lead up to International Women's Day.

The global pop-culture icon is celebrating "the power of friendship".

It's a "full-circle" moment for Barty, she told National Indigenous Times.

She might not have been Barbie's number one fan growing up, but she now sees the impact it has on her nieces and potentially for children around the world.

"They're absolutely obsessed with Barbie so I've had the tendency to play with the dolls more and be more creative as an adult," Barty said.

"Barbie represents so many different people around the world. It represents so many different careers.

"I'm a big believer in you can be what you can see. It creates a curiosity. It creates a dream of what kids might want to do when they're older, whether it's a nurse, a midwife, a teacher, an athlete, a surgeon - whatever it is.

"I think there are so many representations… it really unlocks the curiosity of young girls and boys, from a young age."

Her love for creativity and positivity came through tennis, she said.

"I see my nieces and plenty of girls all around the world. They fall in love with that creativity and curiosity with Barbie and being able to explore what's possible," the former world no.1 said.

"It's obviously an iconic brand, and I'm super humbled and pumped to be a part of it in a really small way."

On the announcement, Goolagong Cawley admitted she has felt like a big sister to Barty.

The pair had some involvement in the design, one that represented a "special moment" for the younger of the two - her 2021 Wimbledon singles win, itself modelled on Goolagong Cawley's attire worn during her career.

Goolagong Cawley is depicted in the dress she wore when presenting Barty her 2022 Australian Open trophy.

"Not every person gets to have a personal relationship with someone who is their hero and has become a friend and a mentor," Barty said.

"We often don't talk a lot about tennis. It's about connecting with each other, and from the first time that we met over 15 years ago now, it just felt like a really easy, genuine, natural relationship.

"I've been very lucky to have Yvonne involved in my life, and in my career as well."

Goolagong Cawley, a seven-time Grand Slam winner and 20th century tennis icon, has dedicated much of her life post-career to cultivating the next generation of Indigenous athletes at the elite level with her self-named foundation.

Barty feels fortunate in her own right to be a role model for young girls around the world "but particularly those with Indigenous heritage, to know that it is possible".

"There's no ceiling, there's no reason why you can't," she said. "It's about exploring what you can do and dreaming about what's possible."
