The world No.2 maintained her perfect record against Emma Raducanu with a straight-sets demolition on Saturday.
Five-time major winner Swiatek is yet to drop a set this campaign, advancing with a 6-1 6-0 thumping of Raducanu on Rod Laver Arena.

So it was no surprise to learn the Pole didn't need any courtside pep talks on Saturday.
But Swiatek still gave the innovation the nod of approval.
"I am not getting so much coaching now but for sure the next matches there will be moments when I need them," Swiatek said.
"And it's nice to have someone to remind you of anything - usually there is not much point in overthinking it.
"It's great that the Australian Open thought of this idea. Also it's interesting for TV to have the coaches so close."
In the build-up to her clash with Raducanu, Swiatek said rankings would count for nothing against an opponent sitting 59 spots below her.
But the Pole, who has the chance to regain world's top ranking if she wins the title, looked a class above in the 70-minute clinic.
Swiatek hit 24 winners to the Brit's nine and dropped just four points on serve, while also converting five of her dozen break points.
The second seed was handed a time violation for delaying the start of the match but pleaded innocence, arguing she was waiting for towels to be delivered.

It was the only minor hurdle for the 23-year-old, who held serve to love in the opening game and rattled off another 11 consecutive games to seal the match in convincing fashion.
Swiatek, whose only loss so far this year was a United Cup defeat to the as-yet unbeaten Coco Gauff, will be a hot favourite in the fourth round against either qualifying 'lucky loser' Eva Lys or world No.82 Jaqueline Cristian.

Eighth seed Emma Navarro took a much tougher route to the fourth round, resisting a fightback from Tunisian former world No.2 Ons Jabeur to advance 6-4 3-6 6-4.
"I love tennis so much I can't resist, I've got to play three sets," Navarro smiled on-court after the physical encounter.
"I came out playing really well and maybe (Jabeur) wasn't playing her best.
"Then she played a really great four games to get it back to 5-4 and a really good second set, and I just wanted to stick in there and keep believing in myself."
Navarro will next meet either Russian ninth seed Daria Kastakina or Kazakhstan's 24th seed Yulia Putintseva.
A host of other women's singles seeds are also in action on Saturday, including former Wimbledon champion Elena Rybakina (six) doing battle with Dayana Yastremska (32) at John Cain Arena.
Elina Svitolina (28) takes on Jasmine Paolini (four), while Madison Keys (19) and Danielle Collins (10) face off in an All-American affair.
Collins, runner-up to Ash Barty in 2022, looms as one to watch after making headlines when she wound up the Melbourne crowd following a hard-fought win over local Destanee Aiava in the second round.
