He finally did it. It took Wawrinka four hours and five arduous sets to see off four-time champion Djokovic. He even had cramp towards the closing stages, but he must surely now be enjoying that unfamiliar feeling of victory. Djokovic, on the other hand, now remembers what defeat feels like, having not lost since the 2013 US Open final before today.

Wawrinka is heading into the unknown and will contest his first Australian Open semi-final on Thursday, but the 28-year-old has so far proven quite adept in handling himself when in uncharted territory.

"A rapidly emptying Rod Laver Arena, where the temperature seems bizarrely to have risen in the last half hour, is still reverberating to the second big shock of the tournament following Serena Williams' exit.

"It was a first win over Djokovic for Wawrinka since 2006, and followed 14 straight defeats, so it's no surprise to hear Stan say he's "really, really, really" happy. The announcer is now beckoning those of us in the upper levels to come down to the front - apparently there's men's doubles coming up. They have some act to follow. Djokovic and Wawrinka press conferences to follow, so stay tuned for reaction."

Wawrinka, the eighth seed, will play Tomas Berdych, ranked one place above the Swiss, for a place in the final.

"It's a really great feeling," said Berdych after his victory over David Ferrer, which happened to be his first win on Rod Laver Arena.

"There were some special moments which went well together in this match - making it for the first time here in the Aussie Open to the semis, winning my first match on Rod Laver after all those years. That's been a very special match to me. I'm extremely happy to go through."

Djokovic had won 14 matches on the trot against Wawrinka but that run has now ended, as have a number of other statistics. The Serb was unbeaten in 28 Tour matches, he was unbeaten in 25 matches at the Australian Open, but in reaching the semi-finals Wawrinka has made sure the world number two has to start from scratch once again.

"Wawrinka has overcome an enormous mental hurdle. He has the ability and has worked on his game, but it's a different matter beating the world's best players and his poor record against Djokovic did not trouble him."

So, it is Wawrinka who adds his autograph to the camera lens, while Djokovic makes his way through the corridors. His three-year reign over and he must now wait at least another year for his fifth Australian Open crown.

"I tried to stay aggressive, to not give up," continues Wawrinka. "I was cramping a little bit, for sure it was a tough one and I was nervous. Now I will go in the ice bath for a long, long time.

"I tried to focus on what I did last year. I tried to be aggressive. Novak at his best is better than me, for sure."

Interviewer Jim Courier asks Wawrinka how did he manage to beat Djokovic and the Swiss takes his time before answering.

"I was playing really good, I tried to fight," says this year's semi-finalist. "I was not feeling great at the beginning. I'm really, really, really happy."

A nervy start from both players as errors, and perhaps tiredness, inflict their game. The game progresses from 15-15 to 30-30, a sloppy forehand into the tape allowing Wawrinka to draw level. And here we go... Match point Wawrinka as a crosscourt Djokovic volley is a whisker wide. What has the defending champion got left? Nothing. Nothing at all. How bows out by patting a volley wide and the defending champion makes an early exit.

"The quality of this match is just getting better and better. The quality of the serving when you consider the fatigue is extraordinary and they are both backing it up with great agility around the court. Something has to give. Perhaps Wawrinka deserves this because of the progress he has made over the last 18 months."

Andrew Neill: , externalAnd everyone thought Rafa's quarter would be the most exciting. Wonderful match this. Neither deserves to lose.

A clench of the first from Wawrinka as he smoothly steers his way to 40-0 and there aren't any obstacles to be negotiated, despite Djokovic finest defensive efforts. The Swiss marches on thanks to a thunderous forehand winner.

Forehand down the line from Djokovic, but Wawrinka respond with a series of crunching hits, forcing Djokovic onto his knees and the Serb nets. The defending champion pulls through, serving out to the wings, and he then knocks Wawrinka onto the canvas, wrong-footing the Swiss with a backhand into the corner.

It's 0100 Down Under but there's no sign of fatigue from the players nor the crowd with both sets gearing up for a crescendo. A backhand return down the line from Djokovic - brilliant - and the Serb blows his fingertips, as if to say 'it's all part of the job, ladies and gentlemen'. Effortless from the Serb and he reins Wawrinka in to 30-30 but the defending champion then falters during another epic rally, netting a forehand on the 19th shot. Wawrinka allowed to wriggle free, another error on the forehand from Djokovic.

"Djokovic's serves are incredibly accurate and short games seize the initiative and put the pressure back on Wawrinka."

Wawrinka taking his time before strolling towards the baseline and Djokovic looks towards the referee. Mind games. Gamesmanship. Djokovic, though, has oodles of confidence, making a trip towards the net and punching away an unreturnable forehand into the corner for a 30-0 lead. It's another hold to love for the Serb who prolongs a set which is in its second hour.

Not even the weather can steal the thunder from Wawrinka and Djokovic. The Swiss lunges before getting back into position. Where were we? 40-15. An ace out wide from Wawrinka and he's contently jogging towards his chair for the changeover.

"Hopefully play will resume in a few minutes' time," says tournament referee Wayne McEwan before a bunch of youngsters jog onto the court with tea towels in tow.

Djokovic takes part in interesting-looking monologue, full of arm gestures and wincing, after screwing a forehand wide. Brutal hitting from the pair at the baseline and it's Djokovic who goes wide on the backhand for 40-15.

Rain drops falling from the night sky to add another twist to this blockbuster and the players run for cover but remain on the court. It all adds to the tension, I guess. What timing by those rain clouds.
