Third seed Alexander Zverev and sixth seed Alex de Minaur both played in rain-delayed matches and needed four sets to book their third-round spots.
Cameron Norrie continued to fly the Great British flag in Melbourne with a four-set 6-1 7-6 (7-3) 4-6 6-6 (7-5) victory over United States' Emilio Nava.
French Open champion Coco Gauff needed just 77 minutes to sweep aside Serbia's Olga Danilovic 6-2 6-2 on Margaret Court Arena.
Two-time winner Aryna Sabalenka spent even less time on court, overpowering China's Bai Zhuoxuan 6-3 6-1 in 72 minutes.
And world number seven Mirra Andreeva also took a convincing 6-0 6-4 win against Greece's Maria Sakkari to continue her bid for a maiden Grand Slam.
Image source, ReutersDay four has been slightly kinder to the British players out in Melbourne, after two days of disappointing results.
In the men's singles, British number two Cameron Norrie progressed to the third round with a four-set win over American Emilio Nava.
The 30-year-old was undeterred by a rain delay as he attempted to close out the match, eventually coming out on top at 6-1 7-6 (7-3) 4-6 6-6 (7-5).
Arthur Fery was outclassed in a straight-set 7-6 (7-4) 6-1 6-3 defeat by Argentina's Tomas Etcheverry. The British number seven came through qualifying at Melbourne Park to secure his main draw spot.
In the women's singles, British number one Emma Raducanu looked out of sorts as she fell to a straight-set 7-6 (7-3) 6-2 defeat to Austria's Anastasia Potapova.
The 28th seed looked good in her first-round win over Thailand's Mananchaya Sawangkaew, but couldn't get going on Stadium Australia.

Image source, Getty ImagesHe is a beast physically and that is how he has made his name. He is the guy who is getting the hours on the practice court and he is conditioned to this.
He understands that the sport of tennis involves running and if you play his style, you are going to run a lot. He makes sure that he gets that time in his legs.
It is a hard play style to sustain over a 10, 15-year period and sometimes you will get ebbs and flows - that is probably what happened when his ranking dropped - but he is in a good moment.

Image source, Getty ImagesCameron Norrie played one of the best matches of his life here two years ago against Alexander Zverev in the fourth round. He played really aggressive and enterprising tennis which we hadn't seen before or since to that degree. He lost it in a fifth-set tiebreak
Abigail Johnson added...
To have lost so many meetings [to Zverev] by that point, it was so encouraging to see him look to completely re-invent himself for that match.
Norrie can credit himself for that. Zverev maybe had more strength and aura than he would now.
Zverev 6-3 4-6 6-3 6-4 Muller
Image source, EPAAlexander Zverev sees off Alexandre Muller to set up a third-round meeting with Great Britain's Cameron Norrie!
That should be a great match.
The German third seed missed his first couple of match points on Muller's game, but completes the job on serve to reach the Australian Open third round for the ninth time.
De Minaur 6-7 (5-7) 6-2 6-2 6-1 Medjedovic
Image source, ReutersAlex de Minaur books his place in the third round!
He didn't have it all his own way, by any means, but eventually overpowered Hamad Medjedovic to complete a comeback win in four sets.
He could face American 29th seed Frances Tiafoe, who is two sets up on Argentine Francisco Comesana.
Alexander Zverev and Alex de Minaur are both on the verge of booking their place in the Australian Open third round.
Zverev holds off Alexandre Muller with an ace at 40-30 to lead 5-3 in the fourth set.
Meanwhile, De Minaur backs up his second break of serve in his fourth set against Hamad Medjedovic with a rapid hold for a 5-0 lead on Rod Laver Arena.
*Paolini 6-2 0-0 Frech
Image source, Getty ImagesWomen's seventh seed Jasmine Paolini has made the perfect start out on Kia Arena.
The Italian did not allow the rain delay to disrupt her rhythm and has taken the opening set 6-2.
There's not been a major shock in the women's draw so far and Paolini looks in no mood to be the first victim of an upset here.
*De Minaur 6-7 (5-7) 6-2 6-2 4-0 Medjedovic

Image source, Getty ImagesIt's interesting to see Katie Boulter courtside earlier on.
She said in her news conference last night that she is a tennis player herself and she has to prioritise her schedule to build momentum in the company of her new coach - and as much as she would love to stay and support Alex de Minuar, she would only do it if her plans allowed it.
Clearly that has enabled her to be here.
De Minaur 6-7 (5-7) 6-2 6-2 3-0 Medjedovic*
Image source, Getty ImagesIt looks as though Alex de Minaur has truly cracked Hamad Medjedovic's resistance here.
After a competitive first set, the Serb's challenge has faded and the sixth seed is cruising towards the finish line on Rod Laver Arena.
The Australian number one backs up his early break of serve for a 3-0 lead in the fourth set.
Norrie 6-1 7-6 (7-3) 4-6 7-6 (7-5) Nava

Image source, Getty ImagesCameron Norrie is in a good moment, he is winning a lot of his tennis matches.
He needs to enjoy himself this evening, and then a big game in a few days, potentially against Alexander Zverev.
He will be ready for that one. It's not the best match-up as he has struggled against him traditionally.
Who knows, let's see what happens.
Zverev 6-3 4-6 6-3 3-1 Muller*
Image source, Getty ImagesCameron Norrie awaits the winner of the match on John Cain Arena.
And he may not need to wait too long to discover who that will be.
German third seed Alexander Zverev is a break up at 3-1 in the fourth set and potentially three games from victory.
However, the 2025 runner-up has just had the trainer out to investigate an issue.
Looks like it could be his ankle, but it didn't prevent him from holding serve there despite coming under pressure at deuce.
Norrie 6-1 7-6 (7-3) 4-6 6-6 (7-5) Nava
Image source, Getty ImagesCameron Norrie speaking on court after his second-round win: "As you can see, the atmosphere is amazing. It was really unreal, thank you guys for staying. The big question is: where's the after-party? We've got to keep going, straight to The Crown! It was nice to get the job done tonight.
"I just want to enjoy this result, I haven't even looked ahead. He [someone in the crowd] backs me, so I'm feeling the confidence from him. The fans have to keep going [behind me].
"Credit to [Emilio] Nava, he was able to serve well and play really well when the crowd was so against him. I bet it wasn't easy. I felt really relaxed coming out here. I was a bit tight on my groundstrokes, but I managed to get it done. It's an amazing feeling, especially with everyone here and some friends in the crowd."

Image source, ReutersIf there was any man for this job in this atmosphere, it's Cameron Norrie.
He absolutely loves it. This is his environment and this is where he looks the most comfortable.
The story of the day was Emilio Nava's forehand - too erratic, took it late and missed wide.
He kept himself so calm and so level in the match but his smile now is cheek to cheek.
Cameron Norrie, take a bow.
Norrie 6-1 7-6 (7-3) 4-6 7-6 (7-5) Nava
Image source, Getty ImagesIt's a spot in the third round for Cameron Norrie!
The British number two comes through his encounter with Emilio Nava in four sets, winning 6-1 7-6 (7-3) 4-6 6-6 (7-5).
The American did manage to defend the first two match points on his serve, but then hit a wild forehand return following a lengthy exchange.
Cameron Norrie is well and truly flying the Great British flag in Melbourne.
*Norrie 6-1 7-6 (7-3) 4-6 6-6 (6-3) Nava
World number 27 Cameron Norrie is ever-so close to the Australian Open third round now.
Emilio Nava gives up two cheap points off serve to hand the Brit three match points.
De Minaur 6-7 (5-7) 6-2 6-2 0-0 Medjedovic*
Alex de Minaur has turned the match around after almost two-and-a-half hours against Hamad Medjedovic.
De Minaur held a 4-0 lead before Medjedovic managed to break the Australian's serve - but any prospect of a fightback was short-lived.
A final break of serve - gifted by a double fault from Medjedovic - leaves the home favourite a set away.
*Norrie 6-1 7-6 (7-3) 4-6 6-6 (4-3) Nava
Cameron Norrie gets play under way.
The British number two is potentially just three points away from securing his third-round spot, having been knocked out in the first round of the Australian Open last year.
Here we go...
