Murray and Brazilian partner Bruno Soares came from a set behind to beat Canada’s Daniel Nestor and Czech Republic’s Radek Stepanek 2-6, 6-4, 7-5.
The Brit lost in the men’s doubles final at Wimbledon and the US Open last year with John Peers but finally went one better with his new partner in the first Grand Slam of 2016.
Soares lost his serve on two occasions in the opening set but he and Murray responded in the second, breaking in the fifth game en route to sealing it 6-4.
That set up a decider and although the British-Brazilian pairing were broken when they first served for the match, it was second time lucky to take the title.
Murray became the first man to win the men’s doubles crown at the Australian Open since Fred Perry and Pat Hughes in 1934 and credited the help he received from his team.
“I’ve got to thank my team – all my success on the court is down to my coach Louis (Cayer). Then Alan MacDonald has been with me for a long time as well,” said Murray.
“I’ve not always given them a lot to cheer but thanks for sticking with me.
“Andy [Murray] should have been in bed, I don’t know why he’s here taking photos. We’ll be there to support him tomorrow.
“I need to thank my wife, she’s not here but she’s at home working hard to pay the bills so that I can travel the world playing sport.
“She’s been there with me for the last seven years, through a lot of good times but a lot of bad times as well. She has always been my rock and I can’t wait to see her when I get home.”
