Federer astounded both the crowd and Djokovic by going 5-2 up in the first set before he was clawed back in by the seven-time Australian Open champion.
Roger Federer says it was "horrible" to play his match with Novak Djokovic knowing he had just a three per cent chance of winning.
The Swiss legend thinks he's capable of adding two more major titles to his record-breaking trophy cabinet and is determined on returning to Melbourne Park next year.
Federer was up 4-1 and 40-0 on Djokovic's serve but the Serb managed to save all three breakpoints to win his first service game as his opponent made an array of unforced errors.

But either by accident or design, there was no meeting between Trump and Thunberg at the forum. From a sustainability perspective, the right, the left as well as the center have all failed.
Federer had sustained a groin injury and left the court to have it treated again after eventually dropping the opening set to Djokovic in a tiebreak.
Still, as Djokovic started slowly focusing on Federer rather than himself, the 38-year-old had some hope.
"I think everyone knows about it", she said.
"Once in the match, I felt like I was probably going to be able to finish, which was a good thing. We did talk about it with the team but it never went there which is good - you're playing careful obviously". "And in between, it's one to forget, because you know you have a 3 percent chance to win".
"It's frustrating, but I don't think I would have gone on court if I felt I had no chance to win".
Sanders and Warren seek advantage as crucial NH primary approaches
Their confrontation, visible to viewers, began when Warren walked toward Sanders and refused to shake his outstretched hand. They were enthused that Sanders recounted how he had asked Warren to run for president before he got into the race in 2016.
"You never know what the future holds particularly at my age", he said.
"At the end of the day, I'm very happy".
Federer saved more break points to force a tie-break but by now Djokovic had stopped missing and was finding some fine offensive shots of his own. The 32-year-old had cryptically revealed after his quarter-final victory over Milos Raonic that there was more bothering him than simply the contact lens problems he experienced, with speculation about a stomach issue.
The next opportunity to gain that 21st title will be at Roland Garros in May, after he confirmed at the end of a year ago that he will be playing all four Grand Slams and the Olympics in Tokyo during his 2020 season.
