Federer and Nadal produced one of the finest contests their rivalry has ever seen but it was the Swiss that prevailed, winning 6-4 3-6 6-1 3-6 6-3 after three hours and 38 minutes on Rod Laver Arena.
It means Federer has secured his fifth Melbourne crown and a first grand slam success since Wimbledon in 2012.
If this was to be the last grand slam duel between this pair, perhaps the two finest players the sport has ever seen, it was more than a fitting finale.Nadal twice came back from a set down, and then led by a break in the fifth, but Federer drew on all his powers of brilliance to win one of the most unpredictable finals in recent memory. Federer is now the first man in history to win five or more times at three different major events, and with 18 triumphs he extends his record as the most successful male player of all time.
For Nadal, this is the third time he has lost in the Australian Open final, having won here once in 2009, but the 30-year-old has made a resurgence of his own and looks ready to return to his best. "Congratulations to Roger and all his team," Nadal said. "I fight a lot to be where I am today. Today was a great match and probably Roger deserved it a little bit more than me so I'm just gonna keep trying. "I feel I am back at a very high level. I am gonna keep fighting for the whole season and keep trying to have this trophy with me." The first set carried added significance given Federer had beaten Nadal only twice in 35 meetings after losing it, and never at a grand slam. A ringing mobile phone cut the tension and, after a slow start, Federer began to dial in too, as three booming backhands gave him the break for 4-3 and he served out with an ace to move one set to the good.

Just as Federer assumed control, however, Nadal wrestled it back, breaking once in the second and then again for a 4-0 lead. He was peppering Federer's backhand at every opportunity but it was the forehand that was creaking most and Nadal cruised through for one-set all. Nadal could now smell his opponent's insecurity and when two more forehands hit the net it seemed the Spaniard was sure to take charge. Instead, Federer dug deep to hold and after being pinned against the ropes, the Swiss suddenly came out swinging. He broke Nadal in the very next game, held in 63 seconds and, with his backhand singing, he broke again for 5-1 and swiftly closed out the set. Bewildered, Nadal had sent three rackets off to be restrung but into the fourth and the momentum swung again.
Everyone stop right now .. take 6 months off. Come back. Win ..... can't believe what I watched. Congrats to my friend @rogerfederer— andyroddick (@andyroddick) January 29, 2017
