Barty breezed through the first set after breaking Dayana Yastremska early, but the Ukrainian battled back to make things tougher in the second set The Australian will face another Ukranian — Lesia Tsurenko — in the first round of the Australian Open on Monday.

Barty won in 85 minutes 6-2, 7-5 in an excellent preparation for the year's opening grand slam event, the Australian Open, starting on Monday in Melbourne.

She had lost her two previous finals on home soil — a nailbiter against Petra Kvitova in the 2019 Sydney International after a straight-sets loss to Angelique Kerber in the 2018 tournament.

"This is incredible … a great start to the year," Barty said.

"I definitely feel the love out here, I love playing in Australia, I love playing at home, it's been incredible for my team to enjoy this week.

"It was nice to get the ball rolling this week … and I can't wait to get started in Melbourne on Monday."

As she builds towards an Australian Open campaign as world number one — another step in an impressive journey from star junior, to out of the sport, to the top of the rankings — Barty said she hoped to inspire young girls.

"I've lived through all of it, I've had my issues, I've had my struggles, but when I became vulnerable and broke through that glass ceiling and just enjoyed being me, that was the best part about it," she said.

"It's a message for all girls and boys, but girls in particular, is just stay true to yourself, enjoy your sport and chase your dreams."

After both players held serve in their opening games of the first set, Barty drew first blood early by breaking the Ukranian to love. Barty then consolidated the break, forcing Yastremska on the back foot with fantastic net play.

Barty broke again to lead 5-2 in a long wait for a Yastremska mistake on serve, before taking out the set in 30 minutes.

Straight away, the Australian broke Yastremska's serve in the first game of the second set, only for Yastremska to battle back with a break of her own as her own service game settled.

Both players hung tough and relentlessly held serve in the second set, putting Barty under pressure when she trailed 5-4.

But she held serve in gritty fashion, before powering through to break Yastremska to love and lead 6-5.

That was all the opportunity Barty needed, sealing the deal on serve to win the title.

Barty's summer lead up to the Australian Open has been anything but straight forward, losing in straight sets in her opening match at the Brisbane International.

She followed that up with hard-working wins over Anastasia Pavlyuchenkova in Adelaide and a straight-sets victory over Marketa Vondrousova, before a tough semi-final win over the US's Danielle Collins.

Barty will face off against another Ukrainian in the opening round of the Australian Open on Monday, taking on world number 120 Lesia Tsurenko as she looks to better her run to the quarter-finals at Melbourne Park last year.

In the Adelaide International's men's final, Russia's world number 18 Andrey Rublev followed up a win in last week's ATP tournament in Doha with victory over South Africa's Lloyd Harris, winning 6-3, 6-0.
