The world No.2 maintained her perfect record against Emma Raducanu with a straight-sets demolition of Britain's 2021 US Open champion.
Five-time major winner Swiatek is yet to drop a set this campaign, advancing with a thumping 6-1 6-0 win 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 Germany's Eva Lys.
Ranked 128 in the world, Lys is the first qualifying 'lucky loser' to reach the women's singles fourth round since the Open moved to Melbourne Park in 1988.
The 23-year-old, who lost to local Destanee Aiava in qualifying, served brilliantly in the final set to close out a 4-6 6-3 6-3 win over Romania's 82nd-ranked Jaqueline Christian.

Ninth seed Daria Kasatkina also advanced, beating Yulia Putintseva 7-5 6-1, and will meet eighth seed Emma Navarro in a huge fourth-round clash.
Navarro got there the hard way, 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."
Sixth-seeded 2023 Open runner-up Elena Rybakina overcame a back complaint that led to a medical timeout early in a painful and hard-earned 6-3 6-4 win over 2024 semi-finalist Dayana Yastremska.
The 2022 Wimbledon champion needed seven match points and will next take on the winner of Saturday night's all-American battle between 10th seed Danielle Collins and newly-crowned Adelaide International champ Madison Keys.
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 Aiava in the second round.
