The crowd cheered for every Murray error in tiebreaker. One man yelled, "Andy, don't choke."
Rather than wilting under the pressure in the fifth set, Murray hit his stride. He allowed Federer only four points in the first three games of the fifth set, bolting to a 3-0 lead and carrying it through to the end.
"It's big. I never beat Roger in a Slam before. It definitely will help with the confidence," Murray said. "Just knowing you can win against those guys in big matches definitely helps."
Federer could see improvement in Murray's approach in the tough situations.
"With the win at the Olympics and the U.S. Open, maybe there's just a little bit more belief," Federer said. "Or he's a bit more calm overall."
Djokovic already owns three Australian titles and is aiming to be the first man in the Open era to win three in a row. The 25-year-old Serb was nearly flawless in his 89-minute disposal of No. 4-ranked David Ferrer in Thursday night's semifinal, and said he was hoping Murray and Federer would go to five sets.
"Obviously, Novak goes in as the favorite, I would think, even though Andy beat him at the U.S. Open," Federer said. "Novak is the double defending champion here. He's done really well again this tournament. Obviously a tough match again, and give a slight edge to Novak just because of the last couple of days."
