Collins had never won a match at a Grand Slam before coming to Australia - now she's won four straight and eliminated No. 14 Julia Goerges, No. 19 Caroline Garcia and No. 2 Kerber along the way.
By the age of nine, Ms Barty was training with boys six years older than her, and at 12 years old, she was playing against adult men.
Rising Australian tennis star Ashleigh Barty feels that her time in the Women's Big Bash League for the Brisbane helped improve her as a person and a player.
A teenage prodigy, Barty spent more than a year out of the game before returning in 2016, including a spell playing professional cricket.
Barty said she was content to play at any time.
"It's just another challenge and another opportunity for me to come out and try to play my best tennis".
Still seven months shy of her 18th birthday, Anisimova produced a sensational run to the fourth round but the teenager came up against too strong an opponent in two-time major champion Kvitova, who eased through 6-2 6-1. "But sometimes it's really important".
"I know that I can match it with the best and when I execute I know I can". She lost in the first round here a year ago.
All of Australia is behind her.
'I think I'd be kidding myself'.
'I mean, she's within the rules of the game, ' Barty said.
"Sport in Australia is very much driven by AFL".
"It's incredible that it's happening in Australia", Barty said.
Her idol is former world No.1, and fellow Indigenous Australian, Evonne Goolagong.
Past year she was named an ambassador for the RSPCA.
The reporter said: "I don't know". "I love when things get competitive". "Rudy, Maxi, Affie and Chino, a mixture of fluff ball breeds".
Wozniacki was among the players most critical of the Russian being given wildcards to ease her return from suspension and when she lobbied against Sharapova receiving one for the French Open - which was ultimately refused - Sharapova's agent Max Eisenbud described her as a journeyman who was fearful of his client preventing her from winning a Grand Slam.
"If anyone is thinking about getting a pet, please check the RSPCA website first, these animals are desperate for good homes".
Sharapova, who was suspended for 15 months for taking the banned drug meldonium in 2016, said Barty's style was hard to play against. She has two older sisters, Sara and Ali, and is also now an aunty. Australian sporting history is littered with legendary tennis players who own multiple Grand Slams, including Margaret Court with a record 24, Roy Emerson with 12 and Laver with 11. The left-hander dropped just the three games as she eased herself to victory against one of the brightest young talents around.
"I think she has the tennis to do it and we'll see if she will be able to manage it mentally and physically".
