That's your lot from us for today, folks.

Defending champion Jannik Sinner is safely through to the last four after a dominant win over home favourite Alex de Minaur.

He'll face Ben Shelton on Friday after the American saw off Lorenzo Sonego.

In the women's draw, Iga Swiatek breezed through despite a double-bounce controversy and will take on Madison Keys for a place in the final.

That is one of two exciting semi-finals that we'll bring you tomorrow, the first sees world number one Aryna Sabalenka continue her bid for a three-peat against close friend Paula Badosa.

We'll be back at 08:00 GMT tomorrow for that. Be sure to join us then!

Britain's Henry Patten says he and Finnish partner Harri Heliovaara will "try and replicate" their Wimbledon success at the Australian Open after the pair reached the men's doubles semi-finals in Melbourne.

The pair claimed a thrilling victory at Wimbledon last year, just three months after joining forces.

They moved a step closer to a second Grand Slam title together with a 6-3 7-5 victory over Monaco's Hugo Nys and Frenchman Edouard Roger-Vasselin in Wednesday's quarter-finals.

Sixth seeds Patten and Heliovaara, who have yet to drop a set at Melbourne Park, will face German duo Kevin Krawietz and Tim Puetz in the semi-finals.

"We've been in this position before, although not in Australia," Patten said.

"And when we were here last we played very, very well, so it's nice to have that in your back pocket."

Britain's Alfie Hewett reached the semi-finals of the Australian Open wheelchair singles before teaming up with Gordon Reid to progress to the last four of the doubles.

Second seed Hewett, the 2023 singles champion at Melbourne Park, claimed a flawless 6-0 6-0 win over Ruben Spaargaren of the Netherlands.

Reid lost his singles quarter-final 6-3 6-7 (6-8) 6-1 to Argentine fourth seed Gustavo Fernandez, who will play Hewett next.

Hewett and Reid - who are top seeds and have won the Melbourne doubles title together on five occasions - then joined forces to beat Japanese duo Takuya Miki and Daisuke Arai 6-2 6-0.

In the women's wheelchair doubles, Lucy Shuker and Japan's Yui Kamiji sealed a 6-1 6-0 quarter-final win over Chile's Macarena Cabrillana and Saki Takamuro, also of Japan.

A clear double bounce in the quarter-final between Iga Swiatek and Emma Navarro has reignited the debate over how tennis uses video technology.

Navarro lost a point when she trailed 6-1 2-2 A-40 despite the ball bouncing twice in front of a stretching Swiatek, who went on to win 6-1 6-2.

Because Navarro continued playing, instead of immediately stopping the point, the American eighth seed was unable to challenge the call.

In the women's draw, Iga Swiatek dropped just three games as she breezed past Emma Navarro to reach the Australian Open semi-finals and continue her bid for a maiden Melbourne title.

Five-time major winner Swiatek was ruthless in a 6-1 6-2 victory over eighth seed Navarro.

Swiatek has dropped just 14 games at Melbourne Park this year - and seven of those came in her first-round match.

The Pole will face Madison Keys in the last four after the American came from a set down to beat Elina Svitolina.

Earlier, Keys continued her own fine form with a 3-6 6-3 6-4 win over Svitolina.

Keys is on a 10-match winning streak and won the Adelaide Open title a fortnight ago.

The 29-year-old is hoping to reach her second Grand Slam final, having lost to close friend Sloane Stephens at the 2017 US Open.

On his semi-final match against Ben Shelton, Jannik Sinner said: "Last year we played some very tough matches.

"Obviously he's one of the best servers on tour, he's a lefty and all different rotation on the ball is coming and hopefully I'm ready and I can return as many serves as possible, and then trying to stay very concentrated about my game like today and staying aggressive. We will see."

More from Jannik Sinner on recovering over the last two days: “Yesterday was a very easy day, I played just 30-40 minutes with my coaches so they gave me a good rhythm.

"Talking generally about physical when you are young you recover very fast, so it’s a bit different and some days I really like to sleep and trying to rest in the best possible way.

"I’m not doing too many things at the moment, just trying to rest and recover and trying to be ready for the court."

World number one Jannik Sinner said on his victory over the home favourite Alex de Minaur: "I was feeling everything, when you break quite early in each set it’s a little bit easier but Alex de Minaur is a very tough competitor, he’s an amazing player and I know so many guys came for him tonight but thank you so much for being so fair, it was an amazing atmosphere.

"We know each other quite well now, we played last year so many times and we try to understand each other’s game and try and prepare each other in the best possible way.

"But these kind of matches can go quickly but they can also change very fast if I go down a level a little bit, he takes opportunities, so I’m very happy about my performance."

Next up for Jannik Sinner is American Ben Shelton in the semi-final.

Shelton reached his first Australian Open semi-final with a battling win over Lorenzo Sonego that took just under four hours.

The big-serving American won 6-4 7-5 4-6 7-6 (7-4) to set up a match with defending champion Sinner on Friday.

Shelton, who clocked a tournament joint-fastest 144mph serve during the match, said he was "relieved" to have gotten through.

"Shout-out to Lorenzo because that was some ridiculous tennis," Shelton added after a quarter-final lasting three hours and 50 minutes.

The numbers back up what we all saw: that this was an imperious performance from Jannik Sinner.

He racked up 27 winners, had a first serve percentage of 64%, winning 84% of his first serve points and converting six of his 10 break points. He also saved the only break point he faced.

If the last round was a real battle, this was a procession.

Alex de Minaur was well beaten in his first home Grand Slam quarter-final as his torrid record against Jannik Sinner continues.

But the crowd on Rod Laver Arena appreciate his efforts, giving him a great cheer as he waves on his way back to the locker room.

Alex de Minaur has been comprehensively outplayed by the world number one.

Stunning from Jannik Sinner.

A sizzling backhand down the line brings up two match points for the Italian.

Alex de Minaur has run out of ideas now and it's unsurprising because ticking the box for every department that Jannik Sinner brings on to the court is just that much better.

Brilliant from Jannik Sinner.

A backhand winner, cross-court and landing millimetres inside the line, puts him a game away from the semi-finals.

Alex de Minaur loses his cool midway through the game after going long and shouts in the direction of coach Adolfo Gutierrez, who can do little for his man at this stage.

Alex de Minaur holds, much to the delight of the Australian crowd.

Even they must have given this one up but they want to see the home favourite keep the match going for a little while longer.

What a forehand across court from Jannik Sinner, it's like he's got a homing device on the ball, it just goes exactly where he wants it to go. He's hitting that ball with full power across court time and time again into a postage stamp between the baseline and the sideline.

It's all looking very straightforward for Jannik Sinner.

Another hold to love and the end is nigh for Alex de Minaur unless he can produce one of the all-time great comebacks.

I wouldn't get your hopes up, folks...

We know that the game is so demanding now, we know these hard courts really pound on the joints.

I think Alex de Minaur will have to develop that net game, more slices, more ability to come forward and finish the points quicker than being able to just pound back and forth across the baseline.
