Welcome to the weird world of pandemic era men's tennis, where the world number five is unmistakably the man to beat.

Novak Djokovic sits head and shoulders above the rest for now, and those ranked higher would surely recognise that too, as the Australian Open arrives.

The 35-year-old Djokovic is playing the tennis of a 25-year-old, and being allowed his liberty after arriving in Australia is good news for him, auspicious for the rest of the Melbourne Park field.

Djokovic was being packed off on a flight out of the country around this time last year, after a saga that made minor international celebrities out of local journalists who could interpret the ins and outs of court proceedings.

He remains unvaccinated against COVID-19 as far as is known, but Australia has relaxed its border controls and rolled out the red carpet for Djokovic this time, rather than arrange for him to be detained.

Had he been allowed to play in Australia and North America last season, Djokovic would surely have remained on the top rung of the rankings ladder.

Over the coming fortnight, Djokovic will chase down a 10th Australian Open title and a record-equalling 22nd men's singles major.

What might stop him reaching those goals? Stats Perform has looked at areas where there might be a crumb of hope for his rivals.

Frosty reception?

There might be the odd jeer. He has never been universally popular and he has, through his vaccination choices, seemingly given those that disliked him anyway another stick to beat him with.

But look, if you think crowd pressure is going to get to Novak Djokovic, you haven't watched enough Novak Djokovic. Move on.

Besides, his 'Nole' army is sure to mobilise in Melbourne. He won't be found wanting for support.

Weight of expectation

The greats in sport rarely get flustered, but perhaps these are the moments, as history approaches, when even a model of focus such as Djokovic might miss a step.

You can look at the 2021 US Open final, when Djokovic was chasing a rare Grand Slam of all four majors in the calendar year, only to lose in straight sets to Daniil Medvedev in the Flushing Meadows final.

He would have gone to 21 slams with that win, too, edging ahead of Rafael Nadal and Roger Federer with whom he was locked on 20 majors. Instead he was flat, out of gas. The greats do have bad days, but they're rare.

Nadal got the jump on both Djokovic and Federer by winning the Australian and French titles last year to unexpectedly surge to 22 slams, before Djokovic took Wimbledon to narrow the gap and Federer retired to make it a two-man race.

Djokovic has won four of his five finals since Wimbledon, with the exception being a surprising loss to Holger Rune at the Paris Masters.

If he loses, it might have to be early, while still relatively cold. Djokovic has a 100 per cent strike rate once he reaches the semi-finals in Melbourne, never failing to take the title once he reaches the final four.

The #NextGen stars

Who are we looking at here, now we know Carlos Alcaraz is going to be absent? The world number one's hamstring blow has only boosted Djokovic's title chances, while removing the tantalising prospect of a first grand slam match-up between the pair. To date, they have only played once, with Alcaraz winning a tight contest on clay in Madrid last season.

In fact, who even is #NextGen? Stefanos Tsitsipas has been around forever, it feels, but is just 24, the same age as Casper Ruud, who is very much on the rise after two slam finals last season. World number three Ruud is just about #NextGen, but fourth-ranked Tsitsipas probably isn't. His slam results have tailed off, and it would be a significant surprise if the Greek made it to the final from the top half of the draw. He has done well in Australia over the years though, with semi-final runs in three of the last four seasons.

Norwegian Ruud is a potential semi-final opponent for Djokovic, and that could deliver drama. Felix Auger-Aliassime is on the other side of the draw and won four titles last year, yet all were relative tiddlers, while it might be too soon for Rune to win over five sets against an all-time great, but he is a possible quarter-final foe for Djokovic.

So is a certain other player, who long left behind the #NextGen ranks...

Nicholas Hilmy Kyrgios

Nick Kyrgios versus Rune in the third round is a lip-smacking prospect. And if that happens and Kyrgios comes through it, despite having not played on tour yet this year, the prospect of a quarter-final against Djokovic would likely loom large.

Tennis being tennis, strange things can happen, but given his kind draw it is hard to see anyone beating Djokovic before the quarter-final stage. Should it be Kyrgios waiting for him at that point, it will be popcorn at the ready.

Last year's Wimbledon final was decided by a fourth-set tie-break, rather than what would have been a dishy fifth set, and Djokovic would again fancy getting the better ot the bellicose but hyper-talented Australian.

Yet Kyrgios has beaten Djokovic twice in their three career meetings, so this is potentially the real landmine on the path to the final. If someone can defuse Kyrgios in the early rounds, Djokovic would have no complaints whatsoever.

Djokovic's own body might fail him

Djokovic abandoned a practice session in Melbourne out of caution over a hamstring issue, but by Friday he was fit enough to face Kyrgios in an exhibition on Rod Laver Arena.

Had he held any serious fitness worries, he surely would have given that a swerve. Showing up sent a message to the field.

This is not to say Djokovic's health will hold and his body will last the distance, but then the same is true of everyone in the draw. This is tennis at the highest level and Djokovic has fought his way to grand slam titles while carrying injury worries in the past, and you suspect he will again, probably as soon as Sunday, January 29.

The Professional Tennis Players Association is committed to equal pay for men and women at grand slam level, according to the man who teamed up with Novak Djokovic to launch the organisation.

Vasek Pospisil, whose on-court doubles efforts helped Canada win the Davis Cup for the first time in November, said the PTPA would "fight for both sides" in its efforts to improve players' prospects throughout the sport.

The breakaway union has caused controversy, with the ATP and WTA, which run the men's and women's tours, adamant they already have significant player representation when it comes to making decisions in the best interests of tennis.

Djokovic quit as president of the ATP player council to become the figurehead of the PTPA, which was launched at the height of the pandemic during the 2020 US Open.

There was initial criticism of the PTPA when no women appeared to be involved.

However, Pospisil said at the time discussions were ongoing, and ahead of the upcoming Australian Open, its first executive committee was unveiled, consisting of four men and four women.

Joining Djokovic and Pospisil are Hubert Hurkacz and John Isner, plus WTA players Paula Badosa, Ons Jabeur, Bethanie Mattek-Sands and Zheng Saisai.

Pay has been equal at all the grand slams since 2007, when Wimbledon announced it would reward women the same amount it pays men.

Asked about equal pay at the four majors and the PTPA's position, Pospisil told Stats Perform: "From day one, we always knew that this would only be successful with the women, and that has always been our goal. And so we're really happy that we're gaining a lot of traction now on the women's side.

"Currently, there is equal pay at the grand slam level, I believe, so that's obviously amazing.

"It is a joint organisation, both men and women, and we'll do everything to fight for both sides.

"Obviously, they're separate tours. The WTA, ATP, and grand slams are joined, of course. So, the staff will have their hands full with trying to advocate for both sides.

"It's a unified player association for both men and women, and we're really proud of that and where we're going."

Those already involved, and those the PTPA will hope to attract, are being advised the union is aiming to bolster the rights – and at the bottom line, the earning potential – of all involved.

There is currently significantly more money on offer on the ATP tour than on the WTA circuit, which points to issues of inequality remaining in the sport.

It has been known in recent times for some high-profile tournaments, where tours converge, to pay its men's champion more than its title-winning woman. This is despite events on both tours being best-of-three-set matches, whereas in the slams women play best-of-three and men play best-of-five, a matter that has long been a trigger for equal-pay debate.

Pospisil believes the WTA has a "smart and passionate" group of eight on its ExCo and said the "energy was amazing" when the group met for dinner on Thursday in Melbourne.

"I just have such a good feeling after a few years of working on this," Pospisil said. "To finally be at the stage where we're ready to go, are launching, got everything we need, and we have amazing player board reps that honestly we couldn't be happier with."

Djokovic, a 21-time singles grand slam winner, is at the forefront, and Pospisil said the 35-year-old Serbian's role has been crucial.

"I feel like you need somebody that is at the top of the sport," Pospisil said. "So, I just think all the players and our organisation, we're very lucky that he's so supportive and that he's stuck his neck out and is fighting for what he believes in and what he believes is right."

Iga Swiatek had a reminder of the stellar rivalry that never was when she practised alongside Ash Barty on Saturday ahead of the Australian Open.

Australian Barty is the reigning women's singles champion at Melbourne Park, but she retired just weeks after lifting the trophy last year.

That shock decision from the then 25-year-old saw a figurehead of the WTA Tour make way, and Swiatek has taken her place as the undisputed world number one, saying Barty has inspired her to hit those heights.

The prospect of Barty and an ever-improving Swiatek fighting for the tour's biggest titles was dashed, and they only ever played twice, with Barty winning both times.

Barty announced on January 6 she is pregnant, and she appears to have no inclination to perform a retirement U-turn.

"For sure, when she retired, I felt like she still had the best tennis out there," Swiatek said after their light-hearted court session.

"So, I was pretty sad that I'm not going to be able to compete against her and maybe win.

"But on the other hand, she gave me a lot in terms of my motivation and my kind of willingness to practise even more and to have more variety on court.

"When I played against her, I felt like she just has all these different game styles and slice. Even in her book, she says she has five types of slice. I don't know how that's possible. I still haven't figured out only one type.

"I have huge respect for Ash. She really gave me huge motivation at the beginning of last season to get even better. I'm kind of grateful for that."

Swiatek will play the first night session match on Rod Laver Arena at this year's championships, taking on a familiar foe in Germany's Jule Niemeier.

At the US Open last September, the heavy-hitting Niemeier led by a set and a break against Swiatek in the fourth round, only to let the Pole back in and eventually surrender the third set 6-0. Swiatek went on to win the title, her third grand slam trophy success.

Niemeier also reached the Wimbledon quarter-finals, and Swiatek is wary of the opening test that awaits.

"We played at the US Open, and you saw how intense that match was, how tough," Swiatek said. "It's not going to be easy.

"But on the other hand, any match in a grand slam is always more intense and more stressful than other tournaments. I'll be ready for it.

"It's nice also that we played not so long ago, so I can take a lot from that match. Now I know how her ball feels on the racket. So, we'll see. But she has the same."

Rafael Nadal has denied he has already decided to follow Roger Federer into retirement after this year's French Open.

The Spaniard wil turn 37 in June, and calling time on his career at the grand slam he has won a record 14 times might be the ideal way to sign off.

Making predictions for the season, Germany's Alexander Zverev told Eurosport: "Unfortunately, I think Rafa will retire at Roland Garros. I don't want it to happen, but I think he will have a great tournament, potentially win it and say goodbye."

That would mean Nadal joining his former great rival Federer in waving goodbye to a glorious career after the Swiss played for the last time at the Laver Cup in September. Nadal's tears that night in London pointed to a realisation his own time on tour was also nearing its end.

However, Nadal denies Zverev has been given any encouragement to throw out such a specific retirement suggestion, which was revealed ahead of the Australian Open.

Nadal is the defending champion in Melbourne, and he also took the Paris slam last year to reach 22 for his career, putting him one ahead of Novak Djokovic.

"I don't know what's going to happen in six months," Nadal said, quoted by Eurosport.

"I have a very good relationship with Zverev, but not enough to confess something like that to him.

"The reality is that I'm here to play tennis, try to have a great 2023, fight for everything that I have struggled throughout my career, and I don't think about my retirement.

“You think about it week after week because that's how you show me at every press conference. But I will answer the same every time you ask me."

Nadal has lost six of his last seven tour-level matches, suggesting he might struggle to make serious inroads in his title defence, which starts against Britain's Jack Draper on Monday.

Asked if he felt vulnerable, Nadal said: "Yeah, of course. Without a doubt. I have been losing more than usual, so that's part of the business.

"I think I am humble enough to accept that situation and just work with what I have today. I need to build again all this momentum. I need to build again this confidence with myself with victories. But it's true that I have been losing more than usual.

"I already have been here for three weeks, practising every day with the conditions, with the best players. That helps a lot in general terms.

"My situation, I don't know what can happen on Monday, but my personal feeling, without a doubt, is better now than three weeks ago, in general terms."

Emma Raducanu is "in a good place" ahead of the Australian Open after an ankle injury threatened her participation.

Raducanu was left in tears after retiring against Viktoria Kuzmova in their round-of-16 match at the ASB Classic.

The 20-year-old won the first set 6-0, but after losing the second set 7-5, Raducanu was unable to continue, sparking fears over her ability to play in the Australian Open in just 11 days.

But with her tournament opener against Tamara Korpatsch now just two days away, the 2021 US Open champion eased fears over her fitness, saying she "fully trusts" her ankle.

"I've been able to do preparation, albeit more limited than usual," Raducanu told reporters on Saturday. "But I'm feeling in a good place to go out there and give it my best shot.

"We were thrown a bit of a curveball but we remained optimistic. It's been a team effort to get me to this place. We've been building it up pretty gradually.

"For the ankle, I feel really good. It's going to be more introducing certain things, and the rate at which we've had to do it has been really quick.

"But I've not really played much tennis ever in my career, so I'm kind of used to it. And I'm not stressed about lack of tennis that much."

In Melbourne, Raducanu will be aiming to go beyond the second round of a grand slam for the first time since her incredible US Open heroics in 2021.

Cameron Norrie missed the chance to cap his New Zealand homecoming as he was beaten 4-6 6-4 6-4 by Richard Gasquet in the Auckland Open final on Saturday.

Norrie grew up in Auckland, and the British number one reached his first ATP Tour-level final in the city in 2019.

But despite repeating that feat and then winning the opening set of Saturday's final, Frenchman Gasquet roared back to lift his first title on the ATP Tour since 2018.

After they split the opening two sets, Norrie looked to be on the way to victory when he held a 4-1 lead in the decider.

But 36-year-old Gasquet rattled off five straight sets, including two breaks of serve, to shock the second seed and become the oldest champion in the Auckland Open's 66-year history.

"It's an amazing title for me, especially now at my age," Gasquet told a post-match news conference. "I really didn't think I would win again.

"I'm 37 this year, so when I came here last week, if you were to tell me next Saturday you will win here, I wouldn't believe it."

Norrie gets his Australian Open campaign underway against wildcard Luca van Assche on Monday, while Gasquet will play fellow Frenchman Ugo Humbert in the first round.

At the Adelaide International 2, Kwon Son-woo defeated Roberto Bautista Agut 6-4 3-6 7-6 (7-4) to take the crown.

Bautista Agut, who knocked out defending champion Thanasi Kokkinakis in the semi-finals, hit back from losing the opening set to level the game with a strong second stanza.

The deciding set went all the way to a tie-break as both players lost two of their service games, but with Kwon 5-4 up in the pivotal tie-break, the world number 84 found two breaks of serve to complete the victory.

The win was Kwon's second ATP Tour title and first since lifting the Astana Open trophy in 2021, while he becomes the first South Korean to win multiple Tour-level titles.

Iga Swiatek starts the Australian Open as almost as strong a favourite to win the women's singles as Novak Djokovic is for the men's event.

Considering Djokovic is a nine-time champion in Melbourne, and Swiatek has never reached the final, that is some going and indicative of the Polish player's dominance on the WTA Tour over the last 11 months.

Swiatek ended last year with eight titles to her name, winning the French Open and US Open among them, and the 21-year-old has accrued more than twice as many ranking points as the next player on the WTA list, Ons Jabeur.

Her ascent to become the dominant woman in tennis has been remarkable, and Swiatek has also earned admiration for her efforts to raise funds for children in war-hit Ukraine.

But is she such an outstanding favourite for the Melbourne Park title as the odds-makers have it?

Since the US Open, she has been a champion at just one – modest by her standards – of the four tournaments she has contested, including the United Cup team event.

Here, Stats Perform looks at five others who might have a say in the destination of the year's first major.

Jessica Pegula

Swiatek was reduced to tears after a 6-2 6-2 drubbing by Pegula on January 6 at the United Cup, her first loss of the year.

She later described Pegula's performance as "the perfect match", and will hope the American cannot always rise to that level.

"It's always hard when you lose, especially when you're playing for the team and your country," Swiatek said at the time, explaining her post-match tears.

Swiatek had won all four of the matches they contested in 2022, dropping only one set, with quarter-final wins on the way to her two grand slam triumphs included in that set.

The result in Sydney, therefore, might have been just a blip, but Pegula is number three in the world for a reason, and Swiatek will surely want to avoid her over the coming fortnight.

Coco Gauff

Is now Gauff's time? There's a question that has been buzzing around the tennis circuit for at least a couple of seasons, despite the American being just 18 years old.

Time, it should be clear, is firmly on her side. She soared to fourth in the rankings in October but has slipped a little since, while remaining firmly established in the top 10.

Given her great talent, Gauff should be resident in the top 10 for many years to come, so we can afford to wait before watching her fly. The sometimes-erratic forehand remains in need of fine-tuning, and Gauff began this year with just two career singles titles to her name after missing out on a trophy in the 2022 season.

However, she reached a first grand slam final last June, losing to Swiatek in Paris, and began 2023 by capturing a title in Auckland where, as top seed, she made light work of the field.

The victory made her the sixth American player to secure three or more WTA-level titles before turning 19 in the last 40 years, after slam winners Monica Seles, Jennifer Capriati, Lindsay Davenport, Venus and Serena Williams.

That is some company for Gauff, who will face Katerina Siniakova in the first rout in Melbourne, to be keeping, and her time will come. It might even come in Melbourne.

Ons Jabeur

After finishing runner-up to Elena Rybakina at Wimbledon and Swiatek at the US Open, Jabeur is targeting a third successive slam final.

The Tunisian would win most popularity contests on the Tour, but she wants one of the big trophies now, and has to be seen as a strong contender in Australia.

Her preparations took a knock with a loss to 18-year-old Czech Linda Noskova at Adelaide International 1, but that will only have made Jabeur work harder in the build-up to the major.

She was gutted to have to pull out of the Australian Open with a back injury last year, and a first-round loss at the French Open followed, but Jabeur came good at the next two majors, albeit falling at the final hurdle.

Aryna Sabalenka

At this time last year, Sabalenka was in crisis, her serve a massive weakness as she struggled to deliver the ball safely.

She recovered from going a set down in three consecutive matches at the Australian Open before losing a rollicking tussle in round four with Estonian veteran and upset specialist Kaia Kanepi.

Sabalenka served a wretched 15 double faults in that match, which was sadly more or less par for her in the early stages of the 2022 season, but the Belarusian got her act together, overcome those yips, and finished the year strongly.

A semi-final run at the US Open was followed by an appearance in the WTA Finals title match, where she lost a close encounter with Caroline Garcia.

Sabalenka began this year not with the serving jitters, but with the Adelaide International 1 title, not dropping a set all week.

She has a big game and with it growing confidence. At the age of 24, she should be entering her prime years, and 2023 could be a special 12 months for the woman with the tiger tattoo.

Zheng Qinwen

The WTA's 2022 Newcomer of the Year winner, Zheng is a 20-year-old Chinese player who could soon follow in the footsteps of compatriot Li Na and begin scooping the biggest prizes in tennis.

How soon? Well, probably not quite yet, but then again very few picked out the then 54th-ranked Swiatek to win the 2020 French Open, the moment that launched her to stardom.

Zheng has rocketed to 30th in the rankings, having begun last year at 126th on the WTA list, and should be considered capable of halving her ranking over this season.

She first came to major prominence at the French Open, when she defeated Simona Halep and for a while also had Swiatek's number in their fourth-round match, winning the first set before menstrual cramps and a leg problem caused her to lose momentum.

The WTA Tour is a learning curve and slam-level success might not come immediately for Zheng, but that newcomer award came her way because she is a player shaping up to have a big say in the sport's future. Along with the likes of Gauff and Swiatek, she could still be a big factor in a decade's time.

Belinda Bencic eased to a 6-0 6-2 final victory over Daria Kasatkina to claim the Adelaide International 2 crown on Saturday.

Both Bencic and Kasatkina did not have to play a semi-final after their respective opponents, Veronika Kudermetova and Paula Badosa, both pulled out with injuries.

Bencic romped to victory in the final though, dropping just two games against her Russian opponent to lift her first title in Australia.

The match lasted just 67 minutes, as the 2021 runner-up converted five of her seven break point opportunities while not facing a single break point herself.

Bencic rattled off eight games in a row to start the final, and though Kasatkina did save some face with a couple of holds late on, the world number 13 finished the job to win in straight sets ahead of the start of the Australian Open next week.

"I'm happy I could show my work here on the court," Bencic told reporters at a post-match news conference. "I thought I played some great matches from the start of the tournament and also against different kind of opponents so I really could test myself out there in every way and just go confidently into the Australian Open."

At the Hobart International, Lauren Davis ended a six-year title drought with a 7-6 (7-0) 6-2 triumph over Elisabetta Cocciaretto in an all-unseeded final.

In the opening set, every game went to serve until the tie-break, when Davis found three crucial breaks to take the advantage heading into the second stanza.

But the second set was not the same tight affair as Cocciaretto, playing in her first Tour-level singles final, collapsed to a 5-0 deficit to leave her staring down the barrel of defeat.

Davis, who herself was playing in a first Tour-level final since winning the trophy in Auckland in 2017, overcame losing the next two games to take the title having not lost a set at the tournament.

Davis was delighted after the match, saying: "I have a lot of emotions going through my body right now. I'm just really happy, really excited. I really had to play my best in order to win today."

Cameron Norrie will get a chance to cap his New Zealand homecoming with a title at the Auckland Open.

The British number one, who spent much of his childhood in New Zealand and Auckland specifically, reached his first ATP Tour-level final in the city in 2019, and has repeated that feat this time out.

Norrie made light work of Jenson Brooksby on Friday, winning 6-3 6-4.

He will face Richard Gasquet, who progressed via walkover due to Constant Lestienne's withdrawal through injury, in Saturday's showdown.

Norrie has won all six of his matches this season, three in Auckland and three at the United Cup, where he beat Rafael Nadal.

"It was an absolute battle with Jenson. A lot of long rallies and I know how well he competes, so it was nice to get it done in straight sets," said Norrie.

"He puts the ball in such awkward parts off the court and I had to come up with a lot of really tough shots on the run and a lot of big passes.

"I was able to serve it out and stay really calm and get over the line, but he's a great player."

At the Adelaide International 2, defending champion Thanasi Kokkinakis fell just short of reaching the final again.

He battled back from a set down to force a decider against Roberto Bautista Agut, but it was the Spaniard who prevailed 7-6 (7-4) 3-6 6-3.

Bautista Agut will face Soonwoo Kwon in the final, after the world number 84 defeated Norrie's compatriot Jack Draper 7-6 (8-6) 6-7 (2-7) 6-3.

Nick Kyrgios insists he is serious about being ready to quit tennis the minute he wins a singles grand slam title.

The Australian went close last year to ending his long wait, only to lose in four sets against Novak Djokovic in the Wimbledon final.

Now aged 27, Kyrgios wants to achieve glory at a major to satisfy that urge, before stepping off the court for good. If it comes at the Australian Open over the coming fortnight, it will be all the better for him.

Asked whether he stood by his previous comments, Kyrgios said: "A hundred per cent. It's a lot of training, a lot of work, and I just want to be able to eat whatever I want, drink what I want to drink and just relax.

"It's a hard lifestyle, the dedication these guys show day in day out. I did a bit of that last year, had a great year to show the world I'm still one of the best.

"I'm going to try to do it this year, and hopefully I can do it, but it'll be hard."

Kyrgios is ranked 21st by the ATP, but that can be considered a false position, given he collected no points for his career-best Wimbledon run. The tours stripped the London slam of ranking points due to its banning of players from Russia and Belarus.

The 1,200 points Kyrgios would ordinarily have taken away from the All England Club would have nudged him towards a top-10 placing.

There is the tantalising prospect of Kyrgios facing nine-time Melbourne Park champion Novak Djokovic in the Australian Open quarter-finals this year, and they went through a light-hearted dress rehearsal on Rod Laver Arena on Friday.

Speaking after that exhibition match, Djokovic said Kyrgios' two wins from their previous three tour-level encounters meant the sky was the limit for the man from Canberra.

"He is 2-1 against me, so as far as I'm concerned he can win anything," said Djokovic.

According to Djokovic, Kyrgios had been unaware of the potential for a meeting between the pair in the Australian Open last eight.

Serbian Djokovic has done his homework though, and appears to have mapped out his potential route to what would be a record-equalling 22nd men's singles grand slam title.

"I have to be honest, I think most of the guys are studying the draw pretty seriously, but you have to take it one match at a time," Djokovic said, speaking on Channel Nine.

"We think every player has so much motivation and inspiration to be able to play his best in the court, to perform well, so you cannot underestimate anybody, you cannot take any match for granted.

"It's a hopefully long two weeks. I know Nick and I are in the same part of the draw – he didn't know that by the way. Before the match I told him."

Novak Djokovic returned to action in front of a packed Rod Laver Arena crowd for the first time in two years, and declared: "It's great to be back."

The nine-time Australian Open champion was denied a role in last year's tournament when his vaccination status, having refused a COVID-19 jab, led to him being detained in a Melbourne immigration centre and later deported.

He was briefly released in January 2022 to practise at Melbourne Park before the tournament began, only to be effectively thrown out of the country days later.

With Australia's border controls having since been relaxed, and vaccination status no longer a condition of entry, Djokovic has had the red carpet rolled out this year, befitting his status as the most successful male singles player in the Australian Open's history.

He faced Nick Kyrgios in an exhibition match on Friday evening in Melbourne, with the stadium court sold out and the match screened on national television.

Kyrgios won 4-3 2-4 10-9, in what was a largely light-hearted encounter, a jumped-up practice session. It inevitably lacked the intensity of their last meeting, when Djokovic prevailed in four sets in the 2022 Wimbledon final.

A fierce backhand from Kyrgios in the match tie-break briefly caught out Djokovic, who was wrong-footed and volleyed out of court before slumping to the floor as though shot.

There was more than a little dramatic licence about his fall, and about the match in general, typified by the pair being joined on court by wheelchair players and a pair of leading juniors for the decisive tie-break.

The result did not matter, though it will if these two meet in the quarter-finals of the year's opening grand slam, as they might after the draw was revealed on Thursday.

Djokovic, who did not appear hampered by a recent hamstring niggle, told the crowd: "It just feels great to be back in Australia, back in Melbourne.

"This is the court and the stadium where I created the best memories of my tennis career. Back in 2008 it was the first time I won a grand slam here, and 15 years later I'm here again, and I'm competing at a high level, so I must be grateful for this opportunity to be here.

"Thank you guys for welcoming me in a good way tonight, I appreciate it."

It was a night for jollity and camaraderie, but should both reach that quarter-final date, Djokovic said: "I don't think we'll be this friendly to each other."

Kyrgios, who defended Djokovic during last year's January crisis, said of the 35-year-old Serbian: "It's so important to have him around.

"One of the greatest already left us last year, Roger [Federer], and I don't think we actually knew how special the guys are to our sport, so every time Novak's around at these events I want to beat him, even though I can't at a grand slam."

The Australian Open begins on Monday, when Djokovic facing Spain's Roberto Carballes Baena first. Djokovic is chasing a 22nd grand slam title, which would equal the men's singles record held by Rafael Nadal.

Kyrgios, yet to win a singles slam, starts against Russian Roman Safiullin.

Iga Swiatek has no interest in what people expect from her and the world number one will not be "living in the past" as she targets more success this season.

Swiatek was in a class of her own last year, winning a staggering eight titles to firmly establish herself as the best player in the world.

A second French Open title and a maiden US Open triumph were the highlights for the 21-year-old in a stellar 2022.

The Pole will start her quest to win the Australian Open with a first-round match against Germany's Jule Niemeier at Rod Laver Arena on Monday.

Swiatek is the favourite to be crowned champion at Melbourne Park, but will not be putting too much pressure on herself.

"When I don't care about what people think and what their expectations of me are, it's easier for me to succeed," Swiatek told BBC Sport.

"That was what I tried my best to do in 2022.

"Although I'm proud of them, I'm not going to try to match my previous achievements because it would not be constructive.

"A season like that is something amazing and rare. Sure, I would love to do it again, but it's not advantageous to live in the past."

Swiatek was beaten by Danielle Collins at the semi-final stage of the Australian Open 12 months ago.

Belinda Bencic will play Daria Kasatkina in the final of the Adelaide International 2, though neither of them had to play a semi-final.

Bencic was due to go up against Veronika Kudermetova in the second scheduled semi-final on Friday, only for the Russian to withdraw due to a hip injury.

It was a similar story for Kasatkina, who received a walkover after Paula Badosa pulled out of their match, citing a thigh problem.

While Bencic and Kasatkina will now get the chance to claim a trophy early in the season, the focus for Badosa and Kudermetova will be on regaining fitness in time for the Australian Open, which starts next week.

Badosa was confident she can recover for the upcoming major, where she has been drawn against American Caty McNally in the first round.

"I'm really disappointed that I had to withdraw because I was really looking forward to the match," Badosa told reporters.

"When I was playing [against Beatriz Haddad Maia], it was a very tough match, especially physical, so I felt a little bit in my abductor. I felt like I pulled it a little bit.

"I feel a little bit worse, so I have the Australian Open ahead, and I hope I can recover for that."

Badosa needed two hours and 35 minutes to get past the Brazilian on Thursday, having knocked off Anett Kontaveit and Kaia Kanepi in the earlier rounds.

"I played three really good matches," the Spaniard said. "I think that helps me, as well, on my confidence for the tournaments ahead. Now it's something that I cannot control, so it is what it is."

At the Hobart International, Elisabetta Cocciaretto set up a showdown with Lauren Davis.

Sofia Kenin, the 2019 champion, fell 7-5 4-6 6-1 to world number 67 Cocciaretto, who has reached her first Tour-level singles final.

"It’s unbelievable for me to be here in the final of such a great tournament, and I’m really happy about my performance," Cocciaretto said.

"[Kenin is] a very good player, I was a junior when she won the grand slam [2020 Australian Open], so for me it's an honour to play against her."

Davis, meanwhile, saw off Anna Blinkova in straight sets. She has not featured in a Tour-level final since clinching the trophy in Auckland in 2016.

Veronika Kudermetova saved five match points as she beat Danielle Collins to reach the Adelaide International 2 semi-finals before Belinda Bencic knocked Caroline Garcia out.

Sixth seed Kudermetova showed great defiance to defeat American Collins 4-6 7-6 (7-5) 6-1 on Thursday.

Kudermetova fended off five match points when serving to stay in the tournament at 6-5 down in the second set and duly forced a tie-break.

Collins, runner-up to Ash Barty in the Australian Open final last year, took a 3-0 lead in the breaker, but back came her Russian opponent to level the match.

The world number nine dominated the deciding set to seal a meeting with Bencic in the last four.

Eighth seed Bencic got the better of WTA Finals champion Garcia 6-2 3-6 6-4.

Garcia broke straight back after going 3-1 down in the final set, but Bencic broke for the fourth time in the match to go through.

Paula Badosa and Daria Kasatkina will contest the other semi-final after beating Beatriz Haddad Maia and Petra Kvitova respectively. 

Elisabetta Cocciaretto saved two match points as she came from a set down to beat Bernarda Pera 5-7 7-6 (10-8) 6-4 in the quarter-finals of the Hobart International. 

The 21-year-old Italian will now face 2020 Australian Open champion Sofia Kenin, who also stormed back to defeat Anhelina Kalinina 4-6 6-3 6-1.

Lauren Davis and Anna Blinkova will do battle in the other semi-final following wins over Wang Xinyu and Yulia Putintseva respectively. 

At the Auckland Open, second-seed Briton Cameron Norrie beat American Marcos Giron 6-1 6-7 (5-7) 6-2 to set up a last-four clash with another player from the USA, Jenson Brooksby, who edged past France's Quentin Halys 7-6 (7-3) 7-6 (7-2).

The other semi-final will be an all-French battle between Richard Gasquet and Constant Lestienne, who both came from a set down to see off David Goffin and Laslo Djere respectively.

Thanasi Kokkinakis is on a roll again at the Adelaide International 2 where the hometown hero and defending champion marched into the semi-finals on just two hours' sleep.

The Australian wildcard saw off Serbian sixth seed Miomir Kecmanovic 6-3 6-7 (4-7) 6-1 on Thursday to set up a semi-final against Spain's Roberto Bautista Agut.

Kokkinakis had a stellar run to the title at this tournament 12 months ago, beating John Isner and Marin Cilic before knocking over Frenchman Arthur Rinderknech in the final.

A first-round exit followed at the Australian Open, although he memorably won the doubles title with Nick Kyrgios. Kokkinakis struggled for the rest of the year, with his ranking currently at 110.

Kokkinakis said after his latest win: "I didn't sleep much last night. I reckon I got to sleep at about five and maybe slept for a couple of hours.

"I just couldn't sleep for whatever reason, so I was trying to conserve energy. I didn't want to use it too much. I had a couple of Monsters [energy drinks] before I started and tried to get going.

"When I'm serving well my whole game follows, and then when my forehand gets going I think I've been hitting my backhand really well this week. If I'm doing those three things, it's a good recipe.

"I grew up on this court when I was eight, nine, 10 years old. I showed up last year, and hopefully I can ride the wave with you guys and keep it going."

Fourth seed Bautista Agut beat compatriot Alejandro Davidovich Fokina 6-3 6-2, while the other Adelaide semi-final will see British player Jack Draper tackle South Korean Kwon Soon-woo.

Draper, who has been drawn to face Rafael Nadal in round one of the Australian Open, beat Russian third seed Karen Khachanov 6-4 7-6 (7-3), while Kwon saw off Swedish qualifier Mikael Ymer 6-1 6-2.

At the Auckland Open, second-seed Briton Cameron Norrie beat American Marcos Giron 6-1 6-7 (5-7) 6-2 to set up a last-four clash with another player from the USA, Jenson Brooksby, who edged past France's Quentin Halys 7-6 (7-3) 7-6 (7-2).
