Ash Barty's beautiful act for Casey Dellacqua after Aus Open triumph

The country was left in tears on Saturday night as Ash Barty celebrated her Australian Open triumph with some of the people who got her where she is today.

The World No.1 completed a dream fortnight at Melbourne Park with a steely 6-3 7-6 (7-2) victory over Danielle Collins in the most-anticipated women's Open final in almost half a century.

Her victory made her the first Australian to win their home grand slam in 44 years after Chris O'Neil back in 1978.

Barty let out a massive roar of relief and delight after sealing the victory, before sharing a beautiful on-court moment with former doubles partner and close friend Casey Dellacqua.

Dellacqua was commentating courtside for Channel Nine during the match, before Barty beckoned her onto the court just seconds after the final point.

The pair shared a beautiful embrace as Barty planted a kiss on Dellacqua's forehead, much to the delight of spectators at Rod Laver Arena and fans watching at home.

“She knows how proud I am of her. Everybody thinks I have done a lot but I cannot explain what Ash has done for me,” Dellacqua told Channel Nine after the match.

“We are so lucky and blessed to have each other. I do not take that for granted for one minute and I am so proud of her.”

Barty added: “She is a bloody legend. And she is a great friend and I’m so grateful and lucky to have her.

"There would not be any other person that I want sitting literally direct across from me.

“When I was on the court, I was trying not to look at Casey. Looking around, trying to look everywhere but Casey, but knowing that if I needed anything, not even that there is anything, to give other than the support and being there because Casey, she changed my life.

“She brought me into the sport again. And allowed me to explore, to grow as a person, and I love her.”

Barty and Dellacqua first played doubles together back in 2012 when Barty was just 15 years old.

Dellacqua served as a mentor as Barty made her way in the sport and helped convince her to come back to tennis after she took a short hiatus in 2015.

They made three grand slam doubles finals without success before Barty snared her first major singles title at the French Open in 2019.

Goolagong Cawley's post-match surprise for Ash Barty

There were also lovely scenes when Evonne Goolagong Cawley surprised Barty to present the trophy during the post-match ceremony.

Another mentor of Barty's, Goolagong Cawley said she wouldn't be able to make it to Melbourne this year for the grand slam, but shocked everyone with her appearance on Saturday night.

"Hell of a surprise," Barty said of the seven-time grand slam singles champion role in the ceremony.

"To be honest, I'm really glad that I didn't know because I think I would have been under the pump, I would've been feeling it.

"I haven't seen her since this time last year so we've got a few more hugs to celebrate. Unbelievable to see her."

Olympic legend Cathy Freeman was also caught on television grabbing her mobile phone to capture Barty's crowning moment.

"Looking up at the end, seeing Cathy, she is an inspiration. She's been an inspiration to so many people all around the globe," Barty said.

"But for our heritage, for our family, she is just the best.

"To be able to share that tonight with Evonne Goolagong and Cathy, a night I will never forget."
