The 2019 Australian Open has been one of the best in recent memory, with upsets, emerging stars and the old guard still going strong.
The action from Melbourne Park in the first grand slam of the year has produced plenty of highglights - and a few lowlights as well.
The women's final on Saturday night between Naomi Osaka and Petra Kvitova showcased some of the most incredible moments the sport of tennis has to offer.
Up a set and a break, Osaka squandered three match points as Kvitova mounted one of the great Australian Open comebacks.

Somehow, Osaka was able to compose herself ahead of the third set to claim a 7-6(2) 5-7 6-4 victory for her second major trophy.
It'll be tough to follow that up, but Novak Djokovic and Rafael Nadal have played in some memorable Grand Slam ties over the years. Their 2012 Australian Open final is regarded as one of the greatest matches of all time.
Ahead of the men's final, Sporting News recaps some of the best and worst moments over the past two weeks.
AUSTRALIAN OPEN 2019 HIGHLIGHTS
ANDY MURRAY RETIRES - MAYBE
The headlines began before the tournament actually got underway, with three-time major winner Andy Murray's tearful press conference in Melbourne.
The Scot spoke about the debilitating injuries he's had to deal with over the last few years and hinted that his retirement wouldn't be far away.
In the aftermath of the shock press conference, Murray came back from two sets down in his first-round loss to Roberto Bautista Agut. It was a defeat that epitomised everything Murray is about - grit, determination and never giving up. The entire tennis world got behind him that night.
The match was followed up with a moving tribute video, but the 31-year-old said on court that he might decide to play on.
BERNARD TOMIC HAMMERS LLEYTON HEWITT
Ok, this definitely wasn't a highlight, but it was one of the biggest talking points of the first week of the tournament.
In case you missed it...you know what, I can't bring myself to recap the whole sordid tale again right now. Go here for the initial rant, and here for some reaction to it.
That's all the time and energy we're going to put into that story for now.
Back to the good stuff.
THE RISE OF ALEX BOLT
One of a few feel-good Aussie stories from this edition of the Australian Open, Alex Bolt won his first ever Grand Slam match in the first round with an upset defeat of American Jack Sock.
The 26-year-old then went on to beat Gilles Simon over five sets, before eventually falling to Alex Zverev in the third round.
Learn more about Bolt right here.
KIMBERLY BIRRELL REACHES THIRD ROUND
Kim Birrell will fly up the rankings when they're updated this week after making it to the third round of the Australian Open.
The Aussie's biggest result was a shock 6-4 4-6 6-1 win over 29th seed Donna Vekic in the second round.
She was ultimately beaten in convincing fashion by Angelique Kerber 6-1 6-0.
Learn more about Birrell here.
FRANCES TIAFOE BEATS KEVIN ANDERSON AND GRIGOR DIMITROV
The next generation is coming, and Frances Tiafoe announced himself as a future star with a couple of intense wins in the first week of the tournament.
South African Kevin Anderson was expected to steamroll the American, but Tiafoe came back from a set down to take a 4-6 6-4 6-4 7-5 win in their second round match.
Two days later, the 21-year-old edged Dimitrov to reach his debut Grand Slam quarter-final - the win came on his birthday as well.
Tiafoe was no match for Rafael Nadal in the quarters though, with the Spanish veteran claiming a 6-3 6-4 6-2 win.
STEFANOS TSITSIPAS
If Tiafoe is on the verge of breaking through, Stefanos Tsitsipas is already there.
The 20-year-old Greek star is already ranked 15th in the world, and that will go up when the new rankings are published.
It was pitted as a showdown between generations when Tsitsipas played Federer in the fourth round. Not many gave the reigning ATP Next Gen champion a chance, but he produced some amazing tennis on his way to a 6-7(11) 7-6(3) 7-5 7-6(5) win over his idol.
In honour of his achievements, a Melbourne restaurant named a souvlaki after him.
We'll be seeing plenty of Tsitsipas in the future.
ROBERTO BAUTISTA AGUT VS JOHN MILLMAN
There have been plenty of comebacks at the 2019 Australian Open, and hometown hero John Millman nearly produced one in his second round match with Bautista Agut.
Set against the backdrop of Tomic's attack at Hewitt and the subsequent fallout, Australian fans loved witnessing Millman dig deep and come back from two sets down to force a fifth frame.
It wasn't to be in the end, but it was a reminder that there are still good blokes in Australian tennis.
ASH BARTY REACHES QUARTER-FINAL
Ash Barty was the big Aussie hope heading into the 2019 Australian Open, and she didn't disappoint.
The 22-year-old didn't drop a set in winning her first three matches, then came from a set down to send Maria Sharapova packing in the fourth round.
For the second match in succession though, Barty was beaten by eventual finalist Petra Kvitova.
SERENA WILLIAMS RETURNS TO THE AUSTRALIAN OPEN
Serena Williams was absent from last year's Australian Open, and the last time she played in Melbourne she won the thing while pregnant.
The GOAT women's player made a triumphant return to Rod Laver, beating Tatjana Maria, Eugenie Bouchard and Dayana Yastremska in straight sets.
She eventually fell to Karolina Pliskova in the quarters 6-4 4-6 7-5.
SERENA WILLIAMS BEATS SIMONA HALEP IN THREE-SET EPIC
It was the world number one taking on the GOAT in the round of 16, and it didn't disappoint.
It looked as though Serena was on her way to an easy win after taking the first set 6-1, but the Romanian fought back to take the second.
There were wild swings of momentum throughout the match, before Williams earned the crucial break in the third set for a 6-1 4-6 6-4 victory.
ALEXEI POPYRIN BREAKS THROUGH AT AUSTRALIAN OPEN
Alexei Popyrin's emergence was just another Aussie success story from the Australian Open.
The 19-year-old beat Mischa Zverev in straight sets to set-up a formidable second round match against Dominic Theim. The Aussie was up two sets and a break when last year's French Open finalist retired through injury.
Popyrin then played a five-set epic in the third round against Lucas Pouille, with the Frenchman eventually winning 7-6(3) 6-3 6-7(10) 4-6 6-3.

SERENA WILLIAMS CONSOLES DAYANA YATREMSKA
There was a beautiful moment of sportsmanship after Williams crushed Yastremska 6-2 6-1 in their third round match.
Widely regarded as a player of the future, 18-year-old Yastremska burst into tears at the conclusion of the match.
Williams rushed over, placed an arm around her and told her she played well.
Read about it and watch the video here.
ALEX DE MINAUR CONTINUES HIS RISE
Just days after playing his Sydney International semi-final and final merely hours apart in sweltering conditions, de Minaur took to the courts at Melbourne Park and continued to show the world why he's one of the next big things.
The 19-year-old beat Pedro Sousa in straight sets, before going five sets with Switzerland's Henri Laaksonen in the second round.
In the end, he was no match for Nadal, who has been in scintillating form over the past two weeks.
Read more about de Minaur's stunning rise to prominence here.
DANIELLE COLLINS THRASHES ANGELIQUE KERBER
Who doesn't love a good old fashioned Grand Slam upset?
Collins, who had never won a match at a major prior to 2019, steamrolled her way through the early stages with wins over Julia Gorges and Caroline Garcia.
But it was her fourth round hiding of Angelique Kerber that really turned heads. Collins sent the world number two packing with a 6-0 6-2 scoreline and eventually lost the semi-final to Petra Kvitova.
AUSTRALIAN OPEN TEMPER TANTRUMS AND MELTDOWNS
There have been a few, but two spring to mind most vividly.
The first was Alexander Zverev obliterating his racquet during his fourth round thrashing by Milos Raonic.
The other is Pablo Carreno Busta's post-match outburst following his hugely controversial five-setter against Kei Nishikori.
The Spaniard was leading the fifth-set tie break 8-5 when a crucial umpiring call went against him. He failed to win another point as Nishikori marched on.
DYLAN ALCOTT WINS QUAD WHEELCHAIR SINGLES
One day after claiming the quad wheelchair doubles, Aussie icon Dylan Alcott took out the singles event over American David Wagner.
It was his seventh Grand Slam singles title, and it was a moment made all the more memorable for Alcott considering it was broadcast on Channel 9.
The 28-year-old gave a moving speech during the post-match ceremony.
AMELIE MAURESMO COACHES LUCAS POUILLE
France's Lucas Pouille became just the second top-flight male player to hire a female coach when he bought on two-time Grand Slam champion Amelie Mauresmo at the end of last year.
It worked wonders.
Questioning his commitment and love for the game after an ordinary back end to 2018, Pouille charged into the semi-finals of the 2019 Australian Open.
NAOMI OSAKA VS PETRA KVITOVA - AUSTRALIAN OPEN WOMEN'S FINAL
This was every bit as good as the final between champion Caroline Wozniacki and Simona Halep last year.
Osaka looked odds on to get the job done in straight sets, but couldn't convert three match points on Kvitova's serve. Then the Japanese star was broken while serving for the title.
After a bathroom break to collect her thoughts, Osaka returned, earned an early break and took her maiden Australian Open title
