After the 25-year-old beat Karolina Pliskova 6-3, 6-7(4), 6-3 on Saturday night, the courts at the ACT's tennis centre filled up fast.

Juniors Alisha Kunar, Zali Ilitch, Zoe Cowles and Yuvani Chhetri were court side on Sunday for their own matches and agreed Barty's win would lead to increased participation in the sport.

Thirteen-year-old Zali said it was a positive the win would inspire more people to get involved in tennis, but only if the newcomers did not beat her on the court, she joked.

Alisha woke up and watched the highlights of Barty's match on Sunday and was in awe of her slice shot.

"She uses it so much and it's a big asset," the 12-year-old said.

"It puts them off balance, because not many players can do it as well as her."

Barty's victory came 50 years after her idol, Wiradjuri player Evonne Goolagong Cawley claimed her first Wimbledon title.

She broke down during the post-match on court interview after realising her dream.

"It took me a long time to verbalise the fact that I wanted to dare to dream and say I wanted to win this incredible tournament," she said.

"Being able to live out my dream right now, with everyone here has made it better than I ever could have imagined.

"I hope I made Evonne proud."

Her win on Saturday marked 10 years since she had won the girls' singles title at Wimbledon in 2011.

It also coincided with Dylan Alcott claiming his second Wimbledon title hours earlier in the quad wheelchair event.

Barty is the third Australian woman to win the tournament and the second Indigenous woman, after Goolagong Cawley won twice in 1971 and 1980, and Margaret Court won in 1970.

"Evonne is a very special person in my life," Barty said.

"I think she has been iconic in paving a way for young Indigenous youth to believe in their dreams and to chase their dreams. And she has done exactly that for me as well.

"She's just been an icon for years and years, and not just on the tennis court, her legacy off the court is incredible."

The Queenslander overcame a serious hip injury, which derailed her chances at the French Open title, to achieve her dream.

Something she described as "nothing short of a miracle".

Her injury was so bad her team kept the news from her that it could have kept her sidelined until August.

"I think now to be playing pain-free through this event was incredible," she said.

"It's funny, sometimes the stars align - you can think positively, you can plan, and sometimes the stars do align, you can chase after your dreams."

However, overcoming her injury to win a Wimbledon title and her number one ranking were still not enough to get the young Canberrans to shift their allegiance behind Barty just yet.

As Zoe and Zali's favourite player is Naomi Osaka, Alisha's was Emma Raducanu for Wimbledon and Yuvani's is Serena Williams for her numerous grand slams.

Maybe gold in Tokyo will do the trick to get them on board the Barty party.
