Ash Barty is ready for "one last crack" on Saturday when she will bid to become a first home winner of the Australian Open women's singles in over 40 years.

The 25-year-old Queenslander powered through to the third grand slam final of her career with a clinical 6-1 6-3 win over Madison Keys on Thursday.

She is 2-0 for her past two finals in the majors, taking titles at the 2019 French Open and last year at Wimbledon, and has looked an unstoppable force in Melbourne.

That theory will be put to the test by Danielle Collins, the 28-year-old big-hitting American who dismantled Iga Swiatek's game in the second semi-final to reach a first slam final.

Barty is dialled in and up for the challenge, looking to land the title that was last won by an Australian when Chris O'Neil triumphed at the 1978 tournament.

"It's fun, it's brilliant to be playing in the business end of your home slam," Barty said in a news conference.

"Saturday's going to be a new experience for me. So I'll go out there and embrace it, smile, try and do the best that I can, and whatever happens, happens.

"It's been an incredible January and incredible summer for us, and I'm really looking forward to having one last crack here, to really go out and enjoy it."

Wendy Turnbull was the last Australian finalist in the women's singles, way back in 1980, and the scale of the achievement in ending the long wait is not lost on Barty, who has already won doubles and singles titles this month at the Adelaide International.

"To be in the finals weekend of your home grand slam is what a lot of Aussie players dream of," she added.

This is modesty, but Barty is now a long-standing world number one, and therefore anything but lifting the trophy would be a disappointment at this stage, with 27th seed Collins looking to spring what would be a major upset.

Barty said she was able to "play the match on our terms" against Keys, pointing to her on-court effort being a collaboration with her support team.

Keys was outplayed and her reflection on the experience of tackling Barty was blunt.

"It's tough, it sucks. She's just playing incredibly well," Keys said. "You have a game plan in your head, but she's just executing everything so well.

"She's serving incredibly well, so you don't get any free points on that; her slice is coming in so much lower and deeper than it was in the past, so it's hard to do anything on that; and then you try to play to her forehand and she can open you up there.

"She's so locked in and focused. I've played her a handful of times and this is easily the best I think she's ever been playing."

Barty, who dabbled with cricket before focusing on tennis, appears to have a work-life balance that would be the envy of many, finding it no problem to unwind once she leaves the gates of Melbourne Park. Enjoying the early Australian dominance in the women's Ashes has only brightened her mood.

"It's pretty easy for me. When I'm not here, I don't think about the tennis too much," she said. "I've got the women's Ashes to watch, which is brilliant, read a book, few coffees, and we're set."

The young Barty who first visited the Australian Open before hitting her teenage years, for a training camp, would stand in awe of the player she has become.

"I'd have been only 11 or 12 years old," she recalled. "To see how professional it was and to see everybody going about their business was really eye-opening.

"My first taste of it was in the juniors and I loved it. Being able to get a taste of that kind of lit the flame. You wonder what you can achieve."

Danielle Collins will face home favourite Ash Barty in her first grand slam final at the Australian Open after dispatching Iga Swiatek in straight sets.

Playing in only her second major semi-final at the age of 28, an assured Collins rose to the occasion to win 6-4 6-1 in dominant fashion on Rod Laver Arena.

The 27th seed from the United States was beaten by Petra Kvitova in the last four of the first grand slam of the year at Melbourne Park three years ago, but she was not to be denied on this occasion.

Swiatek was unable to become the first Polish woman to reach the final of this tournament, struggling with her serve from the start as her bid to win a second grand slam title came to a halt and Collins booked a showdown with world number one Barty on Saturday.

Collins capitalised on a shaky start from the 2020 French Open champion, breaking when the seventh seed sprayed a forehand long after double-faulting in a poor first service game.

An aggressive Collins was a double-break up at 3-0 after her out-of-sorts opponent drilled a backhand wide, but Swiatek sprung into life, winning back-to-back games to reduce the deficit to 4-2.

Swiatek trailed 5-2 after being broken for a third time as she struggled with her second serve and although Collins failed to serve out the set at the first attempt, she made no mistake second time around after firing down two aces.

The Florida native was in the zone, staying on her feet during changeovers, and she struck another blow by breaking in the first game of the second set with a cross-court backhand winner.

Swiatek's frustration mounted as her service woes continued, Collins near flawless with her backhand a potent weapon as she broke again to lead 3-0.

The ice-cool world number 30 showed not a hint of nerves, finishing off the job with another break after earning two match points with a glorious forehand winner and forcing a backhand error from Swiatek to move into the final.

While Collins was at her very best in a brilliant performance, Swiatek looked like she did not know what had hit her.

Swiatek won only three of the 21 points behind her tentative second serve after landing only 60 per cent of her first serves in, and the 20-year-old fell into the trap of feeding Collins' dangerous backhand far too often.

Ash Barty paid tribute to Dylan Alcott after the wheelchair tennis player ended his glittering career with defeat in the Australian Open final.

Alcott, who is the only man to complete a 'golden slam' in quad singles, and has won 23 major titles in total, is retiring at the age of 31.

He lost 7-5 6-0 to Sam Schroder in the final match of his career, as his bid for an eighth straight Australian Open title fell just short.

Alcott, who has been named Australian of the Year, won all four grand slams last year and also took gold in the Paralympic Games, defending his title from 2016.

His run to yet another final in Melbourne has been a remarkable story, and Barty – the WTA world number one who reached the women's singles final by beating Madison Keys in straight sets on Thursday – hailed her inspirational compatriot.

"Dylan for me is at the forefront of that, he has inspired a nation, inspired the whole globe," said Barty when asked about the success Australians are enjoying at the season's opening grand slam.

"We were watching his match today. I was with my physio and when he was giving his acceptance speech, we were both crying.

"I was like, I need to get out there and get ready, get my game on, but to watch Dylan and for him be able to share that moment with so many people here...

"The way that he and the Australian Open have opened up the opportunities for more disabled people all around the world to play tennis and have a go is just exceptional, I couldn't be more proud of him."

Barty and Alcott are just part of an impressive 2022 tournament for home favourites. Nick Kyrgios and Thanasi Kokkinakis will face countrymen Matthew Ebden and Max Purcell in the men's doubles final, while Jason Kubler and Jaimee Fourlis are into the mixed doubles final.

"Unreal, honestly it's just incredible," said Barty on becoming the first Australian to reach the women's singles final since 1980. "I love coming out here and playing in the Australian Open.

"As an Aussie, we're exceptionally spoilt that we're a grand slam nation and get to play at home, in our back yard. I'm just happy that I get to play my best tennis here. I enjoy it, I've played well before and now I have the chance to play for a title. It's unreal."

Ash Barty continued her fairy-tale run at the Australian Open, crushing Madison Keys to become the first local woman to reach the singles final in 42 years.

The two-time grand slam champion continued her impressive form at Melbourne Park with a 6-1 6-3 victory over Keys on Rod Laver Arena on Thursday.

Barty, the world number one, became the first Australian woman to reach the singles final at the tournament since Wendy Turnbull in 1980.

She can become the first to win the title since Chris O'Neil in 1978 when she faces either Danielle Collins or Iga Swiatek in Saturday's final, which she will undoubtedly start as favourite.

Barty has dropped just 21 games on her way to the decider and the reigning Wimbledon champion was again ruthless against Keys, who lost her fourth grand slam semi-final in five such appearances.

The 25-year-old Barty settled well and broke the Keys serve in the opening game.

A powerful forehand created the opportunity before she delivered a cross-court winner off that wing to convert following a Keys drop shot.

Barty only made two first serves in her opening two service games yet did not lose a point.

Spurred on by a hopeful and enthusiastic home crowd, Barty's variety and depth – plus nine unforced errors in five games from Keys – helped her race into a 4-1 lead.

Keys finally won a point against the Barty serve in the sixth game, the Australian forced to save a break point before sealing the opening set in 26 minutes courtesy of a forehand return winner down the line.

The first real signs of nerves from Barty came in the fifth game of the second set, but she dug out a tough hold for 3-2.

Keys had settled, but Barty grabbed the break she was after in the sixth game with back-to-back forehand winners.

Barty looked calm throughout and that did not change as she served out the match in style, booking a spot in the final with a forehand winner.

DATA SLAM: Brilliant Barty on verge of ending Aussie wait

Barty has already ended one long wait – an Australian reaching the women's singles final at Melbourne Park.

She is a win away from ending another by becoming the first Australian winner of the men's or women's singles title in 44 years.

Alize Cornet "felt out of breath all the time" during her Australian Open quarter-final loss to Danielle Collins.

Collins was too good for Cornet in a 7-5 6-1 victory on Rod Laver Arena on Wednesday, reaching her second Australian Open semi-final in four years.

The American 27th seed hit 28 winners and 29 unforced errors in a strong performance against Cornet, who was playing her maiden major quarter-final.

Cornet said Collins, who will face Iga Swiatek in the last four, never allowed her to settle at Melbourne Park.

"Well, she's very powerful, even more than what I expected. Her ball is going really fast in the air and she takes the ball super early," the Frenchwoman said.

"All the time you feel really oppressed. I felt out of breath all the time. I couldn't, like, place my game. She just never let me do it, never gave me the time to do it. Yeah, she's impressive.

"But today she was pretty quiet. She didn't scream that much. When I see her playing on TV, sometimes she's yelling, 'C'mon.' She looks like a lion.

"Today I don't think I gave her enough battle so she could express herself."

Collins was playing her first quarter-final since the 2020 French Open and dictated from the outset against Cornet.

The 28-year-old hopes her experience in the latter stages of tournaments helps her late in the Australian Open.

"Yeah, I think now that I've made quarter-finals at French and semi-finals here before, I think I can use those experiences to certainly help me in the tight-pressure moments on court. I can use that to my advantage," Collins said.

"Last time I was here in the semi-finals I had never done that before. I've made some deeper runs in tournaments since then. Hopefully I can carry the confidence that I've gained over the last couple years and be able to use that to my advantage."

Iga Swiatek came through a huge battle against Kaia Kanepi to advance to the Australian Open semi-finals on Wednesday.

Swiatek, the Polish seventh seed, made her second grand slam semi after a 4-6 7-6 (7-2) 6-3 victory over Kanepi on a warm day on Rod Laver Arena.

The 2020 French Open champion held off Kanepi, who suffered a seventh defeat in as many grand slam quarter-finals.

Swiatek fought hard and needed three hours, one minute to progress to a meeting with American 27th seed Danielle Collins.

The steadier start was made by Swiatek, with Kanepi saving break points in each of her opening three service games.

But the Pole was having some trouble with her serve, a fifth double fault giving Kanepi a break point in the seventh game, the Estonian converting with a fine forehand return winner.

Swiatek held after a gruelling 16-minute ninth game, saving four set points as the Rod Laver Arena crowd started to come to life.

Kanepi had won only one set in her six previous grand slam quarter-finals, but she eventually served out the opener against Swiatek, converting her ninth set point.

After Kanepi broke in the opening game of the second set, Swiatek – who was starting to move the veteran around the court – reeled off four straight games.

However, Kanepi responded, a pair of Swiatek double faults helping her break back in the seventh game on the way to a tie-break.

Swiatek was the more consistent of the two players in the tie-break to send the quarter-final into a deciding set.

After the players traded breaks early in the third set, Swiatek took a 3-2 lead after Kanepi sent a forehand narrowly wide before managing a tough hold in the sixth game.

Swiatek charged into a 5-2 lead and while her attempt at serving it out did not go to plan, she sealed her win with another break after a tremendous defensive point.

DATA SLAM: Swiatek hard to beat at majors

It takes a fair bit to beat Swiatek at a grand slam.

The 20-year-old is now 30-2 at majors against opponents ranked outside the top 30 after getting past world number 115 Kanepi.

Danielle Collins ended Alize Cornet's dream run and reached her second Australian Open semi-final with a straight-sets win on Wednesday.

Collins moved into the last four in Melbourne for the second time in four years thanks to a 7-5 6-1 victory on Rod Laver Arena on Australia Day.

The American 27th seed, who will face either Iga Swiatek or Kaia Kanepi in the semi-finals, was in solid form in warm conditions.

Collins was the aggressor throughout against Cornet, who was playing her maiden grand slam quarter-final in her 63rd main-draw appearance.

It was Collins who dictated the majority of points from the baseline early and landed a break of serve in the fourth game.

Cornet saved three break points, but there was no denying Collins on her fourth opportunity, a powerful return setting up a simple volley winner for a 3-1 lead.

Collins looked the more comfortable in the warm weather, but Cornet hung in there and broke back when her opponent was trying to serve out the first set, the American's backhand letting her down with three unforced errors.

But Cornet dropped the first set when serving to stay in it, saving two set points but not a third – set up with a Collins forehand winner down the line – as she framed a forehand long.

Collins crushed a forehand return winner to break serve in the second game of the second set to take complete control of proceedings.

She broke to love to grab a 4-0 lead, cruising through the second set on her way to another last-four appearance in Melbourne.

DATA SLAM: Contender Collins finding consistency

The dangerous Collins has found consistency since the back end of last year.

She is now 31-7 since July 12, 2021 and will be hard to stop by either Swiatek or Kanepi in the semi-finals.

Ash Barty was told how her backhand slice has been compared to that of Roger Federer, but the women's top seed at the Australian Open is not convinced.

Barty produced a stellar display as she saw off Jessica Pegula in Tuesday's quarter-final, losing just two games over the entire duel as the American proved no match.

Her victory sets up a semi-final clash with another American, Madison Keys, with Barty aiming to reach the final of her home grand slam for the first time.

Barty was ruthless against Pegula, firing 17 winners to her opponent's seven, while she won five of the nine break points available to her.

But it was her backhand slice – one of the most recognisable shots in the women's game today – that was particularly notable to four-time grand slam winner Jim Courier in commentary, who compared Barty in this respect to Federer.

Not that Barty was having any of it.

"That's very kind from Jim," Barty told reporters afterwards. "I think everyone's shots are unique.

"I think obviously Roger has one of the most exceptional slice backhands in the game. Mine's a long way off that. Absolutely, no stretch of the imagination we are even on the same page at all.

"But I love to use my slice, I love to get creative with it, to use it offensively and defensively. Over my career I've learnt it is a weapon for me.

"I try and use it when I have to. Sometimes I try and use it when it's my choice and I can be really, really aggressive with it.

"But being able to use it with variety and have different options has been a massive part of my game through this last couple of years of my career."

When Barty faces Keys in the semi-final, she will have already matched her personal best at the Australian Open – she also reached the last four in 2020.

But the combination of being world number one for over two years and having two grand slams under her belt is helping her maintain focus this time around.

"[It's] a bit of both. I think the process hasn't changed, but obviously the familiarity of knowing what to expect or expect how my body feels and almost be able to deal with those emotions a little bit better has probably changed and grown as I've become more experienced," she continued.

"But the processes for us haven't changed regardless of whether it's a first round of the tournament, latter stage of a grand slam, it doesn't actually matter the process before we walk out on court.

"But it's exciting, and I think also being able to embrace the excitement of being in with a chance to play deep in your home slam, it's pretty cool. I think going out there and enjoying that and really embracing that experience helps for sure."

Ash Barty was in clinical form to swat aside Jessica Pegula 6-2 6-0 in just 63 minutes and book her spot in the Australian Open semi-finals.

The world number one is still to drop a set at her home slam in Melbourne and made easy work of her opponent as Barty continued her bid to become the first female Australian singles champion since Chris O'Neil in 1978.

Barty won nine games in a row from 3-2 up in the first set to take complete command and she can now prepare for a semi-final showdown with another American in the form of Madison Keys.

A nervy-looking Pegula was rushing her shots in the early exchanges and Barty broke in the first game when a forehand cross set up a break point chance that her opponent put into the net.

Barty had chalked up 12 unforced errors by game four, but it was her aggressive tactics that had Pegula completely on the ropes and when a thumping forehand set up another break point in game seven, it was little surprise when it was converted.

By this point Barty was in complete command and Pegula had no answer to the variety of shots her opponent rained down on her.

The second set raced by in just 28 minutes, with Barty putting the finishing touch on a mightily impressive performance when Pegula put a return long on the second match point.

"Jess is an incredible person and a brilliant girl. I love to test myself against her. She's had sensational couple of years, she's definitely a top-20 player, there's plenty more to come for sure," Barty said after the match.

On reaching the semis in Melbourne for the second time after doing so in 2020, she added: "I've grown as a person, as a player, I'm a more complete tennis player.

"Credit to my team, they do so much work behind the scenes to make me the best version of myself, I love playing out here. Hopefully I've got a little bit more left."

DATA SLAM: Barty serves up a treat again

Barty defeated both Pegula and Keys en route to winning her maiden slam title at the 2019 French Open and history could be repeating itself here with the world number one playing arguably the best tennis of her career.

Behind her dominance is phenomenal success on serve. Barty is still yet to drop a set in Melbourne, and went 63 games without being broken before Amanda Anisimova did so in the previous round. Here, she lost just five points on first serve (22 of 27, 81 per cent) and gave up just a solitary break-point opportunity in the match.

Madison Keys is enjoying being the underdog after moving into the Australian Open semi-finals on Tuesday.

The American was too good for Czech fourth seed Barbora Krejcikova 6-3 6-2 in their quarter-final, played on a warm day in Melbourne.

Keys reached her fifth career grand slam semi-final, but first since the 2018 US Open.

Riding a 10-match winning streak after claiming just 11 victories in all of 2021, Keys is staying focused as her run continues in Australia.

"I honestly feel pretty neutral, to be completely honest with you. I have gone into every match thinking I can absolutely win any match that I'm out on the court," she said.

"I will say it's been kind of nice to be the underdog for the first time in a long time.

"It's really just not even in my head about winning and losing. It's really just going out, competing, trying to do what the game plan is.

"If that's not working going to Plan B. The rest is kind of not even getting into my brain."

The heat on Rod Laver Arena seemed to get to Krejcikova, the French Open champion taking a medical timeout late in the first set.

Krejcikova said she would learn a lot from her run after struggling with the heat on Tuesday.

"Today it was the heat with some physical conditions that started to bother me during after five games. I mean, from there on, you know, I just couldn't put it together," she said.

"Just still I didn't want to end it up. I wanted to finish match. I wanted to try to do my best. Yeah, I wasn't really able to do that. Still I think it's a really good experience and I can learn a lot from it."

Keys will play either Ash Barty or Jessica Pegula in the last four.

Madison Keys moved into her first grand slam semi-final since 2018 with a straight-sets win over Barbora Krejcikova at the Australian Open.

Keys overcame Czech fourth seed Krejcikova 6-3 6-2 in hot conditions on Rod Laver Arena on Tuesday.

After a hard-fought 50-minute first set, Keys handled the heat the better of the two, closing out a deserved victory.

The win booked Keys a first major semi-final since the 2018 US Open and fifth of her career, with either Ash Barty or Jessica Pegula awaiting her.

After claiming just 11 match victories in 2021, Keys is on a 10-match winning streak, although she was challenged by Krejcikova, particularly early on.

A pair of break points went begging for Keys in the second game before she dug herself out of a 15-40 hole to hold for 2-1.

Keys held after a gruelling 18-point fifth game, one which looked set to be hugely important, after saving four break points.

Another lengthy game followed as opportunities, this time for Keys, came and went before Krejcikova sent a forehand wide to hand the American a 4-2 lead.

Krejcikova took a medical timeout at 2-5, but there was no stopping Keys taking the first set in 50 minutes.

The unforced errors continued to come from Krejcikova and a tame backhand into the net handed Keys a break in the opening game of the second set.

Looking increasingly weary, Krejcikova was broken to love in the third game, although the French Open champion did get one of those breaks back immediately.

Krejcikova continued to fight, but Keys powered away, breaking for 5-2 on her way to the last four.

DATA SLAM: Keys lands top-five win

Keys, the 2017 US Open runner-up, held an 8-20 record against top-five ranked opponents, and 2-6 at grand slams, heading into her meeting with Krejcikova.

Kaia Kanepi surprised even herself by holding her nerve to eliminate second seed Aryna Sabalenka in a final-set tie-break and reach Australian Open quarter-finals for the first time.

The world number 115 edged a topsy-turvy battle 5-7 6-2 7-6 (10-7) on Margaret Court Arena to set up a meeting with Iga Swiatek in the final eight.

With Monday's impressive comeback win, Kanepi has now completed a clean sweep of reaching the quarter-finals of all four majors, making her the 15th active player to do so.

But after squandering four match points in the 10th game of the deciding set, Kanepi admits she struggled to keep her nerves in check when the match went the distance.

"I thought I was going to lose it after the match points I had on my serve," said the 36-year-old, who finished with 30 winners and 30 unforced errors.

"It was really difficult to come back. I don't know how I managed to do it.

"I was really tight. My hand was shaking when I started serving. I didn't make any first serves in, and that added to the pressure.
 
"It was quite crazy. I think I would be more happy if I won after two, three match points. It was really close that I lost the match. I feel a bit exhausted right now.

"The Australian Open was the only quarter-final grand slam I was missing. Given my age, I didn't actually believe I was going to do it. I'm really happy."

After sealing a 14th career victory over a top-10 opponent, with her second win in a row against Sabalenka, Kanepi is now relishing Wednesday's battle with Swiatek.

That will pit the youngest and oldest remaining players left in the draw against each other, with 20-year-old Swiatek having earlier defeated Sorana Cirstea in three sets.

"I haven't watched her, I never played her, and I don't know how her ball feels, so we'll see when I play her," Kanepi said of her next opponent. "What I expect is to play good."

Kanepi is one of six Australian Open quarter-final debutants remaining, with top seed Ash Barty and Madison Keys the only two to have previously reached this stage.

An emotional Alize Cornet said "it is never too late to try again" after reaching her maiden grand slam quarter-final with victory over Simona Halep at the Australian Open.

Cornet, who celebrated her 32nd birthday on Saturday, battled to a 6-4 3-6 6-4 victory in stifling conditions on Rod Laver Arena to set up a last-eight showdown with Danielle Collins, who beat Elise Mertens in three sets.

The Frenchwoman has now defeated two in-form former number ones in Halep and Garbine Muguruza, having also recovered from a set and 1-4 down to overcome Tamara Zidansek.

She is through to her first quarter-final in what is her 63rd grand slam appearance and is the first Frenchwoman to reach this stage at Melbourne Park since Marion Bartoli in 2009.

Cornet is playing in her 60th straight major, and should she compete in the main draws at Roland Garros, Wimbledon and Flushing Meadows, will set a new record for consecutive appearances in grand slams.

"It feels amazing," Cornet said in her on-court interview with Jelena Dokic. "It was a battle with Simona today. In this heat after 30 minutes we were both dying on the court.

"We kept going for two and a half hours with all our heart. Congrats to Simona because I know she struggled a lot and I admire this player so much. 

"She's such a fighter and an example to me. To beat her today to go to my first quarter-final is a dream come true. I don't know what to say. It's just magic. It's never too late to try again.

"This is why I keep playing tennis, for this moment where I can share all these emotions on the court with you."

Cornet had reached the last 16 at majors on five occasions prior to her victory over Halep in a run dating back 13 years when narrowly missing out on the Australian Open quarter-finals.

She was pegged back from a set and break up against Halep, losing 16 straight points at one point, and was clearly struggling with the heat as the match dragged into a decider.

But Cornet, who recently suggested this might be her final season playing professional tennis, showed incredible resolve to break Halep in the seventh game and hold her own serve to break her quarter-final hoodoo.

Halep congratulated Cornet, posting to her official Instagram account: "You have been stronger today! All the respect for you, Alize. Enjoy. I'll keep working to get better for another three-hour match when we meet again."

In her post-match media duties, Halep said: "I have only nice words about her, because I like her on court, how she's fighting.

"She deserves what is happening to her now. She works hard all the time, and I wish her good luck. I really want her to make this dream coming true."

There was to be another emotional moment for Cornet at the end of her victory speech as she praised 2009 Australian Open quarter-finalist Dokic for her work off the court since retiring eight years ago.

"I want to thank my box, but also I want to tell you something... how you moved on in your life, I think we can all congratulate you. You were an amazing player and now an amazing commentator," Cornet said as the pair embraced on court.

Dokic, who last week called out social media trolls for body-shaming her, responded: "You just made me cry. I can’t believe I'm crying. Thank you. Alize Cornet."

World number one Ash Barty promised to carry on playing her own game after booking her spot in the last eight of the Australian Open.

Barty, the top seed, defeated Amanda Anisimova 6-4 6-3 on Sunday to progress to the quarter-finals in Melbourne for a fourth successive time.

Anisimova defeated last year's champion Naomi Osaka in the last round, but she proved no match for Barty, who sealed the win in 74 minutes.

Barty did see her run of holding serve ended, however, after 63 games without being broken, though it was a minor blip in another convincing win. 

Indeed, the 25-year-old has now won all four of her Australian Open ties without dropping a set.

Asked what was key to her dominant form, Barty said: "I think the most important thing is I just try to be me, continue to be me, that's all I can do.

"That's what I’m good at, that's who I and who I want to be."

Her comments were well received by the crowd at Rod Laver Arena, and Barty is delighted to be playing in front of spectators once again.

"The last two years have been extraordinarily tough for a lot of people around the world," she said.

"To have the crowd here, it brings a lot more to the tennis. It makes it a lot more enjoyable for me to play at home."

Barty struck seven aces and registered a first-serve percentage of 78, while also hitting 23 winners and making exactly half the amount of unforced errors as Anisimova (17 to 34).

"Amanda is an incredible athlete and incredible competitor. It's nice to see her back playing her best tennis," Barty continued.

"I enjoyed sharing the court with her and testing myself against her. It was nice to be able to hold firm tonight."

Asked in a post-match news conference about dropping serve for the first time in eight matches, Barty replied: "It didn't bother me too much.

"Honestly, I'm not counting how many games I hold in a row or not. The fact I was able to reset, break straight back, was really important, just to be able to reset myself, go again and continue to do the right things."

Next up for Barty, a two-time major winner who is yet to taste victory in her home grand slam, is another American in the form of Jessica Pegula, who upset fifth seed Maria Sakkari 7-6 (7-0) 6-3.

"It's going to be a challenge for me to try and push her off that baseline and make her uncomfortable and feel like she has to create," Barty told reporters.

"But I know that she's also going to be doing the exact same thing to me and trying to make me uncomfortable.

"That's the chess game that we play. You go out there and have fun with it, see who can execute better on the day, and that's about all there is to it."

Ash Barty's dominant form at the Australian Open continued as the world number one saw off Amanda Anisimova to reach the quarter-finals.

Anisimova shocked 2021 champion Naomi Osaka in the last round but the in-form Barty proved a step too far on Sunday.

Barty had not dropped a set in any of her previous matches and the Australian continued that trend with a 6-4 6-3 triumph that took just 74 minutes.

The 25-year-old missed five chances to break before she finally nosed herself ahead in a tightly contested first set when Anisimova went long.

Anisimova made the same mistake in the next game, failing to grasp the opportunity for an immediate response, and Barty struck a forehand winner to claim the set.

World number 60 Anisimova responded by racing into a 40-0 lead at the start of the second set, only for some sloppy shots to allow Barty to haul herself level.

The American held her nerve though and looked to be right back into it when she broke Barty in the next game.

Yet two-time major winner Barty hit straight back, with a missed backhand from Anisimova gifting her a reprieve, and she did not look back, holding serve before breaking again to go 4-3 ahead.

Anisimova saved two match points in her win over Osaka, yet another overhit backhand sent Barty through to a tie against Jessica Pegula at the first time of asking.

DATA SLAM: BARTY'S HOLD STREAK OVER

There was one negative for Barty, who failed to hold serve for the first time in 63 games when she was broken in the second set. However, the Queenslander responded to that streak ending with a display of her title-winning quality to reach a fourth successive Australian Open quarter-final.
