He wasn't happy with his start, though, as Federer raced to a 3-0 lead within nine minutes in imperious fashion, eventually winning the opener in just 24 minutes.
Roger Federer broke down in tears after claiming a record-equaling sixth Australian Open title here on Sunday. Federer also became the only male player who won two different Grand Slam titles at least six times, achieving that here in Melbourne and at Wimbledon.
The 36-year-old, who is the fifth-oldest (36 years, 173 days) to advance to a Grand Slam final in the Open Era, has won their past three meetings, and three of four at the majors. He had been hitting more than 80 percent of his first serves in the third set. Federer got the crucial double-break in the fourth game before adding the finishing touches.
Federer's 80 percent first-serve win percentage ended up being a key factor. Cilic protected his serve well in the tiebreak-the pair traded mini-breaks early on-and earned two set points with a huge return and forehand.
Former Australian Open finalist John Lloyd: "What I loved about it is that he's surprising himself".
"It's a long day waiting for the finals, it's easier when it's in the afternoon: you sleep, go out there, you play". Since the Swiss had not been broken all match, it seemed like the championship was over unless Cilic could produce a miracle. Then first match for the final to play with the roof closed, it's hard. During the 2 hours, 49 minute match, Halep had her blood pressure and pulse taken by a trainer after complaining of feeling dizzy.
The Swiss maestro wobbled at times in the face of some fierce resistance before winning 6-2 6-7 (5) 6-3 3-6 6-1.
"I have to stop", a moist-eyed Federer said before breaking down. Cilic couldn't come up with answers to challenge Federer's service game, which has truly stood the test of time. Another forehand victor gave Marin a breathing space in game seven, saving another break point, and he broke Roger for the second time in succession a few minutes later with a similar shot, taking a 5-3 advantage and serving to send the match into a decider.
Cilic is next scheduled to play in Buenos Aires, in February.
But Cilic fought back gamely to win the second set 7-6 and tie the gripping final 1-1. A clearly rattled Cilic changed rackets in the third game, hoping to slow the momentum slightly.
Tournament referee Wayne McEwen has the option of closing the roof when the temperature reaches 40 degrees Celsius (104 Fahrenheit) and a measure called the wet-bulb globe temperature - which combines factors such as heat, humidity and breeze - reaches 32.5C (90.5F). "It could have been the best two weeks of my life, but Roger played a great fifth set", Cilic said.
However, the graceful Croatian was vivified into a grinding fightback in the second set, saving four break points and was one point away from levelling in the 10th game. Marin Cilic hit out at the decision to close the roof on Rod Laver Arena for the Australian Open final today, saying he was not prepared for the much cooler conditions.
Despite fighting a lone battle against Federer and most of the crowd, he reeled off five consecutive games to extend the champion into a deciding set.
Roger Federer continued to defy his advanced age as he won his 20th Grand Slam men's singles title in Melbourne, Australia on Sunday.
"When I think of it in all those terms, for my money, and I'm not going to speak for people, but he has to be one of the greatest sportspeople of all time, if not the greatest sportsperson of all time".
