And with that, it's time for us to wrap this up.

Not quite the semi-final we were hoping for, but ultimately a result we've seen so many times before - Roger Federer marches on to another Grand Slam final.

Hyeon Chung, the unseeded 21-year-old from South Korea, has had a tournament to remember, and waves goodbye to a whole host of new fans in Melbourne.

Marin Cilic, the sixth seed who ended Kyle Edmund's run, awaits Federer in the final.

Can Federer make it back-to-back Australian Open titles? Or will Cilic exact some revenge for his Wimbledon defeat to the Swiss master?

Until next time...

There'll be some classic Roger Federer, and some untimely blisters for Hyeon Chung.

'There's no one quite like Federer'

David Law

Radio 5 live sports extra commentator at Melbourne Park

A fascinating insight into what Roger Federer is like and how much he enjoys being a tennis player.

There's no one else quite like him in the sport, in terms of people he just enjoys the sport.

Holiday friends

What does Federer think of his final opponent, Marin Cilic, who he played in the final of Wimbledon last year?

"We saw it against Rafa and Edmund - he brings power and everything," said the Swiss.

"He's a really nice guy. He had similar problem as Chung in the final at Wimbledon. It will help him that he's had two days off and he hasn't had to come through a tough semi-final. We'll see a fresh Marin. He believes he can come this far, he will go far.

"We actually saw each other on vacation in the Maldives a couple of months and we played together. We were both looking for a hitting partner!"

'I'll be watching the women's singles'

Chung retires

Federer has also been speaking about tomorrow's women's singles final between Simona Halep and Caroline Wozniacki, who are both aiming for their first Grand Slam.

"I would love to be in that position again," he said. "It's one of the coolest moments as a player.

"I think they've both saved match points so far. Like a cat, you have multiple lives. You've got to keep trying and keep believing.

"They've both worked so hard. The winner will be number one which is a great scenario. I'll be watching. They're both such nice ladies.

"I remember when I won my first. It rocked my world."

Chung retires

Roger Federer has just told a nice story about how he took his tennis racquet to the Maldives, and bumped into Australian Open final opponent Marin Cilic...

As you do.

'I was going to be happy with one more major'

Chung retires

Federer on his progress from last year: "I know how hard it is to win in any major. Years ago I ran into the Novaks and Rafas along the way and they blocked me for some time. I was going to be happy to win one more before I retired. Now here we are, I'm one match away from another."

What does Federer's trophy cabinet look like? "I have most of them at home. Not all of them. I have a nice trophy cabinet. Sometimes I go through it and think 'wow' and sometimes I'm like 'it's just tennis'. When we have friends round it's cool to look at Olympic medals and trophies. It's something I've worked very hard for."

Andrew Neill: Hopefully that gives #Federer a bit of time to work on his first serve before Sunday. Can't get only 32% in in the first set v Cilic and expect to be ok.

Richard Hinman: Retiring from your first slam semi-final against the greatest ever because of blisters is beyond strange.

Martin Litte: I play tennis just like Roger federer... The problem I have is my alarm clock keeps waking me up.

'Chung will be top 10, for sure'

Chung retires

Here's more from Roger Federer on 21-year-old opponent Hyeon Chung: "Fighting was a problem today. I could tell something was wrong, but he has a great composure.

"I think he's going to achieve next level excellence - top 10 for sure.

"I can see why he beat Novak (Djokovic) and Sasha (Zverev). He's going to be a great, great player."

'He's had a wonderful tournament'

Chung retires

Roger Federer speaking on court: "I thought the first set was normal. I couldn't tell what was going on with my opponent.

"In the second set I felt he was getting slower. He's had a problem with the blister. It hurts - a lot. At some point it's too much and you make things worse.

"Clearly I'm happy to be in the final but not like this. He's had such a wonderful tournament."

Chung retires

Some reaction from Roger Federer, Australian Open finalist for the seventh time, to come now...

Chung retires

Federer 6-1 5-2 Chung

That was the most nonchalant retirement from the Korean, he just strolled over to the umpire and that was that...

He must've been hurting though, those blisters he had seen to a few games ago didn't look too tasty.

A disappointing end to a fantastic tournament.

That's all a bit disappointing. You feel sorry for Chung and for the crowd.

Well, Hyeon Chung has just walked over to the umpire and told him he's retiring.

Roger Federer is into the Australian Open final.

Federer 6-1 5-2 Chung*

Hyeon Chung is serving to stay in the second set.

There's a murmur of applause around the Rod Laver Arena as he strolls up to the service line, there's a bigger cheer when Roger Federer cracks a winner on to the white of the line in return.

That's all frame though from the Swiss - 30-15.

At 6-1 4-1 down, the last thing you need is a thumping great blister on your foot. Chung looked like he could run forever during his win over Djokovic, but four days later the 21-year-old is well into uncharted territory and being pushed and pulled all over the place by Federer.

Chung has won just 19 of 51 baseline rallies so far, and those feet are going to have to do a lot more work if he's getting back into this.

Federer looks like he's down the park with his kids.

Federer 6-1 5-2 Chung*

Wonderful from Roger Federer, he barely has to break stride with a serve that forces Hyeon Chung wide and a winner into the space vacated by the young Korean.

The defending champion mixes it up with a thumping forehand towards the body of Chung, who dribbles a response into the net.

*Federer 6-1 4-2 Chung

That's better. A cracker of a first serve that Roger Federer can't force on target.

Federer goes long off the next rally, too - 40-15.

Can Chung put this service game away? He does, a confident crosscourt forehand winner to finish.

Federer 6-1 4-1 Chung*

Hyeon Chung to resume on serve.

He loops a deep forehand towards Roger Federer that the Swiss punches wide, but then double faults.

I see it as a benefit that Chung had that medical timeout. It just pauses everything and it might slow Federer down a fraction. It might allow Chung to get a few more games.

Phil Beck: Chung is good, that's not in question, but he's so raw. Faced so many break points against weaker opposition throughout the tournament but got away with it. Federer is ruthless, and is punishing him.

David Thackeray: Chung will not give up without a fight and will chase every ball. Not over yet, and 15 years could take its toll if Chung could take a set.

A moment's contemplation for him and the crowd.

It looks heavily strapped. It's the ball of the foot, on the bone which leads to the big toe. Any time he was trying to slide it would radiate pain.

It's not just the foot that's hurting. He's not matching up well with Federer.

Medical timeout for Chung

Federer 6-1 4-1 Chung*

Hyeon Chung has his trainer on, he's looked a little uncomfortable throughout this semi-final - a shadow of the charismatic youngster who shocked Novak Djokovic earlier in the tournament.

Blisters are the suggestion? Ouchy.

This is almost uncomfortable to watch - such is the dominance of Roger Federer.

You feel a bit sorry for the opponent as there's nothing you can do. How can you play against this?

Federer 6-1 4-1 Chung*

Not much Hyeon Chung can do about that ace. Postage stamp stuff from Roger Federer.

Another hold for the defending champion.

*Federer 6-1 3-1 Chung

Federer is working Chung side to side like he's putting him through a bleep test - except this one comes with a punishing forehand winner at the end of it.

Never got that at school.

A pacy Chung return proves to punchy for the Swiss at the net, and he then goes long with a forehand.

The Korean has found his footing - 40-30.

This is the second argument with the umpire in a couple of matches!

Feisty Federer, eh? He doesn't let anything go.

Federer breaks

*Federer 6-1 3-1 Chung

What happened there? Chung gets the point, Federer isn't happy.

He questions the umpire, who said the call came after Federer hit the shot.

Still two break points to go. Federer's response is to curl this one on the backhand side beyond the despairing Korean.

Chung goes long, he's unraveling in this one.

Three break points Federer.

Not known for their poetry, the Swiss.

Great chocolate, wonderful watches and, well, fantastic tennis players.

Roger Federer shows just why he is the greatest export of all with a thumping forehand winner that just flirted with the line.

Chung scuttles towards the net and pops an uncomfortable backhand into the tape - 0-30.

Well, this is relentless from Roger Federer on serve at the minute.

Fizz, bang, wallop, Chung just can't get to grips with it.

Hold to love.

*Federer 6-1 1-1 Chung

Roger Federer can't coax a return beyond the net, it cracks the tape and drops on his side of the court.

Hyeon Chung toys with the 36-year-old, before Federer frames a one-handed backhand wide.

He holds.

Federer 6-1 1-0 Chung*

Hyeon Chung's service style is unique, he almost ends bent over double on his follow through.

The Korean is sprightly enough to spring back into a position to play the return, and he sticks a Federer short ball into the space left by the Swiss for a wonderful winner.

30-15.
