That's all we've got time for today.

But don't forget to join us back here from 08:00 GMT on Friday for the second men's semi-final between defending champion Roger Federer and 21-year-old Chung Hyeon of South Korea.

BBC Radio 5 live will have online commentary from the Rod Laver Arena.

See you then!

BBC Two

If you fancy catching up on the highlights of today's semi-finals, tune into BBC Two from 17:00 GMT.

We'll bring you all the drama from Caroline Wozniacki's win over Elise Mertens in the women's singles, as well as Simona Halep's victory over former champion Angelique Kerber (my match of the tournament so far, for what it's worth).

And, of course, you'll see all the best bits from Marin Cilic's win over Kyle Edmund.

This is not the first semi-final we’ll see Kyle in. He’s too good an athlete. Mentally he’s very focused. We’re used to seeing Murray grumpy and miserable for hours on end if he misses a shot! Kyle is the opposite.

He has a really great attitude and that should carry him a long way. He’ll be a top 10 player for sure. Maybe higher...

The Bryan brothers are out on court knocking up, the spectators are still gathered in Garden Square, but in terms of British interest in the men's singles, this tournament is done and dusted.

Nobody predicted that Kyle Edmund would make it to day 11 and he has not only jumped well inside the top 32 that would mean seeding at a Grand Slam, he has rocketed in terms of estimations around what he can achieve.

The immediate question is whether he will be fit for next week's Davis Cup tie in Spain, and we should get an idea within the next half hour when Edmund is due to face the media - stay tuned to BBC Sport to find out...

Ryan: Kyle has had a cracking start to 2018. He has already beaten Dimitrov, Anderson, Shapovalov and Chung and we haven’t even finished January. He is looking so much better than this time last season and there are so many positives to take from this fortnight.

I think he’ll do really well on the clay. It’s almost his preferred surface. The problem is there’s so many guys that are clay specialists and are better on it than the hard court. I think in time, Kyle will prefer the hard court. He’ll get a little bit more oomph. You see how aggressive he can be. Grass may be a place he will struggle because players will be able to get to his backhand more.

Chris Whyte‏: I'm glad Kyle Edmund slumped off the court, #bbctennis, external - it shows he's not happy with a semi, and that's a winner's mentality. Good for him.

BBC Radio 5 live

On BBC Radio 5 live later today, there will be an hour-long special from the Australian Open to discuss Kyle Edmund's run in Melbourne and how far the 23-year-old can go from here.

Tune in from 21:00 GMT.

Marin Cilic on potential finalist Chung Hyeon: "He played a few extremely great matches and I think over here the court suits him nicely for his game. His moving is probably one of the best on the tour. It's amazing to watch him and great to see him coming back nicely."

And on Roger Federer: "I think, with my own game, if I'm serving well and playing aggressive, I think I can match him with that game. It's always difficult if you are running around and he is controlling the point."

If you missed any of that match (oi, where were you?) then you can read all about it in Piers Newbery's match report right here.

You can see how much it means to him!

And in his current form, he's got to fancy his chances for a second Grand Slam title - four years after his first.

Edmund will be bitterly disappointed right now but what a launching pad for 2018.

Marin Cilic on Kyle Edmund: "He's playing great tennis and had an extremely tough run to the semis. Definitely, it left some scars on his body - I can feel that too. Definitely, he has a bright future ahead of him."

Cilic has had injuries and odds and ends over his career. This is a very good sign.

Marin Cilic, speaking on court: "I think in the second set I was a bit up and down with my game and not getting enough returns back. He started to serve quite good. I stayed mentally very focused and tried to play every single point. It was crucial in the tie-break to keep that pressure.

"I noticed in the third game in the third set, he let a couple of balls go. I was seeing that his movement was restricted so I was trying to move the ball around."

Marin Cilic is speaking on court now. He's become the first person from Croatia - male or female - to reach the Australian Open final.

He'll play the winner of tomorrow's semi-final between defending champion Roger Federer and Hyeon Chung of South Korea.

Kyle Edmund looks somewhat forlorn, but it's been a spectacular fortnight for him.

Kyle Edmund slinks off court with his head buried in his chest.

He should hold it high, in truth. What a tournament this has been for the 23-year-old from Yorkshire.

He's going to jump into the top 25 in the world when the rankings are published next week.

Bravo.

Cilic volleys home at the net for two match points.
