It was a women's final that absolutely delivered.

More from champion Madison Keys after winning her first Grand Slam: "I just want to say thank you to my team - this is where I'm going to cry - I have wanted this for so long.

"I've been in one other Grand Slam final and it didn't go my way, and I didn't know if I was going to be able to get back into this position to win a trophy again.

"My team believed in me every step of the way. They believed in me when I didn't believe in myself and helped me every step of the way.

"I love you all so much and I cannot wait for more. I just want to say thank you so much. I'm so appreciative towards every single person who helped me continue to believe in myself and push on to achieve this dream."

Australian Open champion Madison Keys speaking on court: "Bear with me because I'm absolutely going to cry. There is no way I get through this without tears, so sorry in advance!

"Firstly, Aryna you are an unbelievable player and I'm glad I got you back.

"You are always so tough to play against and we always have the craziest matches. Congratulations to you and your team for another amazing Grand Slam run.

"Thank you to everyone who came out and cheered the last two weeks. I always feel so at home here.

"I made my very first Grand Slam semi-final here in Melbourne, so to have won my first Grand Slam in the same place means the absolute world to me."

"Bare with me, I'm absolutely going to cry," Madison Keys tells the crowd.

Finally, she has her hands on one of the sport's major prizes.

Addressing Aryna Sabalenka, she jokes: "I'm glad I got you back."

It draws a big smile from her opponent. Fair play to both of them - but especially Keys, as I'm not sure many would have risked making that joke...

More from runner-up Aryna Sabalenka, who has got a smile on her face as she jokes about her team: "Should I say anything to my team? Why are you laughing? As always that's your fault guys!

"I don't want to see you for the next week - I really hate you! Thank you so much for everything and blah, blah blah.

"I think we did our best, just Madison was doing incredible and I couldn't do anything in this match. Next time I play Madison I will bring better tennis. Of course, sending love to my team. I love you even though we lost."

Runner-up Aryna Sabalenka speaking after her defeat by Madison Keys: "It's OK, I hope I see you next year! First of all, Madison, wow. What a tournament. You have been fighting really hard to get this trophy, you have been playing unbelievable tennis, you crashed it tonight. Congrats to you and your team, really well deserved. Enjoy the celebration, enjoy the fun part.

"I want to say thank you to every one who makes this tournament happen, thank you for making my stay comfortable. I really feel at home every time I am here and even though I didn't get it this time I will be back stronger and will do my best next year. Thank you guys for an amazing atmosphere throughout. You guys are amazing.

"Of course thank you to all the sponsors, tournament director, everyone who was helping - I am speechless - thank you so much."

First up is Aryna Sabalenka.

In good spirits despite her obvious immediate disappointment, she acknowledges her team by jokingly blaming the defeat on them. She says she still loves them, despite the defeat, to laughs from the crowd.

And she's already plotting how to come back stronger next year.

Full quotes coming right up.

It is a case of potential fulfilled, isn't it?

When we first saw Madison Keys at the Australian Open, everybody thought that she would win a bunch of Grand Slams and she would be in amongst the bunch.

But she hasn't been - up until now - and, to be honest, it never looked like she was going to.

She has done it the hard way as well, you only have to look at the players she has had to beat along the way.

Right then, time for the trophy ceremony.

Former champion Evonne Goolagong Cawley leads the tributes to both players' efforts, before we will hear from the players themselves and watch Madison Keys end her long wait for a major title.

And, yes, Aryna Sabalenka has now returned after her post-match meltdown.

What have we just seen?! That was just something else.

It was a slow burner of a match but, once it got going, it really came alive.

Madison Keys just brought it when she really needed it most - and she did leave it all out there.

She was brave. She played some absolutely sizzling winners. She was middling the ball. She was standing tall against the pressure.

She did exactly what she needed to do to prevent her having any regrets.

Madison Keys is also the first woman to defeat both the world number one and world number two at a Grand Slam since Svetlana Kuznetsova at Roland Garros 2009.

She's also the first to do so at the Australian Open since Serena Williams in 2005.

Along the way, Keys also put out the sixth and 10th seeds.

She really had to earn this.

How long a wait has she had?

Well, only two players have required more appearances to win their maiden Grand Slam singles title during the Open Era.

They are Flavia Pennetta (49) and Marion Bartoli (47).

This was the 46th Grand Slam appearance of Keys career, and only her second ever major final don't forget - eight years after her first.

Aryna Sabalenka quickly leaves the court, her hopes of winning three-in-a-row at the Australian Open in tatters.

Madison Keys, fresh from producing one of the performances of her career, is sat on her chair soaking it all in.

She cannot stop smiling. This is her moment, and how she has had to wait for it.

Aryna Sabalenka smashes her racquet to absolute pieces before burying her head in her towel.

Madison Keys is overcome with emotion, wearing a beaming smile as she embraces her team by the court.

Sport.

Aryna Sabalenka saves the first match point.

Madison Keys will have two match points in Melbourne!

This is absolutely incredible from the American.

Oh my goodness - I thought that was out!

I can't believe Madison Keys made that forehand down the line. I mean it was literally by a whisker.

How on earth has she made this ball? She used her legs, absorbed it all and that might win her this championship.

Madison Keys immediately puts the pressure on Aryna Sabalenka by taking the opening point.

What a return that is, my word!

I said this was a free hit for Keys and she lets rip on a backhand return for 0-30.

The 19th seed is two points away from an almighty upset!

Aryna Sabalenka buries a forehand winner into the corner for 15-30 but Madison Keys responds, as she must at this stage.

Incredible shot. Keys crouches low to crush a forehand winner away from Sabalenka before getting over the line to guarantee herself a tie-break at the very least here.

She'll have a free hit on Sabalenka's serve first, though!
