Phew. And with that, it's time for us to take a breather.

We'll be back tomorrow for more Australian Open fun, with players such as Roger Federer, Angelique Kerber, Juan Martin del Potro and Simona Halep in action.

You can keep an eye on all of the live scores from Melbourne, as well as catch up on all of today's action over here.

In a bit.

Sixth seed Marin Cilic has also made his way into the last 16.

He beat America's Ryan Harrison 7-6 (7-4) 6-3 7-6 (7-4) in two hours and 32 minutes.

Just the 53 winners for the Croat in that one...

There is still play going on in Melbourne.

French Open champion Jelena Ostapenko has forced a deciding set in her match against Anett Kontaveit.

And second seed Caroline Wozniacki is just about to get under way over on Rod Laver, as she faces off aganst Kiki Bertens.

Nick Krygios, speaking on court: "Tsonga is a great guy, a champion of the game, someone I looked up to as a kid. I was just happy to get through.

"To be in the locker room with these guys, the first year especially, was surreal.

"I have got a tough match against Grigor Dimitrov tomorrow now.

"He is an amazing athlete who finished the year strongly last year, and the best-of-five sets might suit him."

On Will Smith's presence courtside: "When I saw him out here, I was so nervous. I just wanted him to think I was cool!"

Nick Kyrgios, genuinely, looks as pleased as punch as he makes his way off the Rod Laver Arena to a standing ovation.

Up next for Nick Kyrgios? Grigor Dimitrov.

Kyrgios beat Dimitrov in Brisbane a few weeks back, on his way to claiming the title. It should be a corker.

Nick Kyrgios says he was nervous playing Tsonga because "he was someone I looked up to as a kid, and he's someone I still do."

Lovely stuff.

Australia have not always been convinced by Nick Kyrgios, but that was a performance to win over his home fans. Such flair, such heart.

Kyrgios was 2-5 down in that tie-break and I honestly thought we were settling in for a fifth set.

What fight he's shown out there. The celebration - pumping his arms, screaming at his box, yelling in delight - says it all.

Ace! Three points in a row for Kyrgios.

Quick feet, and Kyrgios is up at the net, meeting a Tsonga volley with a shot of his own.

Match point...

Long goes the Tsonga forehand! He grimaces and touches his right knee.

And Kyrgios claws back another point! Brilliant work, wrong-footing Tsonga up at the net, and again, his opponent clutches as his knee.

Aggression from Kyrgios, swiping a forehand through Tsonga's racquet.

Change of ends, but more fine work up at the net from Tsonga, covering all of Kyrgios' shots, put him within one point of forcing a decider.

Down the line goes Kyrgios as Tsonga comes forward, but it's out by millimeters.

Delicate aggression again from Tsonga, a volley extending his lead. Kyrgios gives him the thumbs up and a "well played."

Double fault from Kyrgios!

He covers his face with his racquet, half with his hands, and yells.

A forehand gets him on the board.

Lovely.

Up to the net comes Tsonga, drops the ball delicately over, and the first point goes his way.

Tsonga will serve to get the tie-break going.

First point goes Kyrgios' way with a big serve, before a delicious volley from Tsonga draws them level.

Smash goes Kyrgios, thudding the ball well out of Tsonga's reach, before another serve goes the Australian's way.

Tie-break time...

Right then.

Deep breath from Kyrgios as he bounces the ball right under his eyeline. Here we go...
