Ashleigh Barty has been given a sporting hero's welcome home at the Queensland Tennis Centre and has confirmed she will play in next year's Brisbane International.

The world number one and French Open champion was greeted by Premier Annastacia Palaszczuk and about 70 junior players who also enjoyed a hit with the tennis champion on Pat Rafter Arena.

Barty said she was looking forward to playing on home soil.

"So excited to come back here and play in 2020 — it'll be home in my own bed, playing in my backyard, and I can't wait for hopefully a really full crowd and see lots of kids out here," she said.

"I'm more driven and more and more hungry than ever to try and get better — there are still so many players out there that I want to beat.

"Regardless of what number is next to my name that passion and attitude won't change."

Barty said her success has not "really sunk in to be honest".

"It's been just the most incredible journey for us and my team — it's happened very quickly," she said.

"We had plans and goals for this year to try and crack into that top 10 and that was kind of the next level for me and then to be able to get to world number one so quickly has been incredible.

"We worked incredibly hard for it and enjoyed every single minute of it and now the challenge for us is to keep improving and try and stay there as long as we can."

'I'm still the exact same person'

Barty said the support she has had from the Australian public has been "really incredible".

"I've always received a lot of love and support from the Australian people and from across the globe, but now it's just gone to a new level," she said.

She said the way she lives her life had not changed at all.

"I'm still the exact same person — I just have a different number next to my name," she said.

"I think that is the most beautiful thing about this journey — it hasn't changed who I am."

Barty cemented her hero status with the tennis juniors today by having a hit with them on the Pat Rafter Arena.

Tennis junior Josie Horan was one of those who enjoyed a rare opportunity to rally with the world number one.

"It was really fun and she's such an inspiration for young women," Josie said.

Gabriella Henzell also got a hit.

"Incredible, like a dream come true — she's so polite and kind and amazing," Gabriella said.

"The fact that I got to hit with the world number one … I'm incredibly happy right now."

Barty is the first Australian woman to hold the number one ranking since Evonne Goolagong Cawley in 1976.

Her advice to young players is to "just enjoy it and do your best every single day".

Fans noticed Barty was sneaking references from Disney movies into her interviews, quoting lines such as "the seaweed is always greener in someone else's lake" from The Little Mermaid and "Hakuna Matata" from The Lion King.

After her Wimbledon loss, Barty drew on inspiration from the musical Annie to sum up her attitude, telling reporters "the Sun's still going to come up tomorrow".

"That was just for a bit of fun for us," Barty said.

"I watch Disney a little bit and am a bit of a fan of Disney and it was a challenge to myself — we picked a quote before going into press and I had to try to work it in there somehow, which was a bit of a challenge.

"The Little Mermaid was a bit of challenge for sure, so we'll see what's next."
