20 Grand Slam singles titles! A quite mind-boggling feat of brilliance, determination, professionalism and longevity all fuelled by a simple, unconditional love of the game.

Okunade: Thanks to Cilic. He didn't make this a boring final. He was indeed a worthy opponent.

Matty Hernandez: Even at 36 years of age how much has @rogerfederer got left in his tank? The man defies physics & logic. Congratulations on your 20th Grand Slam.

Here's Tennis Australia president Jayne Hrdlicka: "Roger, what a performance, you're an inspiration to so many people around the world.

"You work so hard and your commitment to excellence in everything you do really is extraordinary to watch.

"We congratulate you on winning your 20th Grand Slam in your history."

Joanne Pen: So so happy that Federer has won a 20th grand slam What a champion. Incredible at 36 to win like that. He is utterly unique.

Steve Canete: How best to describe Roger? I've ran out of things to say.

Kenni: Roger Federer...the best there is, the best there was and certainly the best there ever will be.

A few years ago you thought he was over the hill. But he redesigned his game, he's fit again and he's come back a better player. He's changed his racquet and his backhand.

I don't know if he'll play the French Open but I don't see anyone touching him at Wimbledon.

On a fast court, Federer is my favourite every time.

Barely a bead of sweat on the champ after three hours' work...

Stick with us for reaction from both finalists, it's time for the presentation at Rod Laver Arena...

It was a good performance from both players. You've got to hand it to Cilic, he had to play the best tennis and keep it up. That was the problem.

Federer was consistent the whole way though. Other than a few double faults and a few patches, it was good consistency.

Roger Federer drops into his seat, puts his arms in the air and embraces the rapturous applause from the Rod Laver Arena.

What an effort from the 36-year-old. Three hours and two minutes, but he has his sixth Australian Open title.

Federer has previously won 19 of these, but he has a look of a man who's never done it before.

He may be 36, but he shows no sign of ageing.

He's proved yet again he's too good for the rest of the world.

A shout from the crowd puts off the Swiss, who ducks out of his serve routine and takes a moment to compose himself.

Cilic gets the second serve back, but Federer's response is fierce.

40-0. Three championship points.

Dan Venn: A visible change in body language from Cilic; end of the fourth he looked determined, now striking a figure devoid of ideas with an increasingly vocal Federer on the brink.
