Axar Patel also starred for India with his three-wicket spell, keeping his rich vein of form going against the reigning T20 World Champions.
Chasing 187, India didn't have the best of starts as openers KL Rahul (1) and Rohit Sharma (17) were out inside the first four overs.
But Kohli and Suryakumar batted with authority, hitting boundaries and sixes at regular intervals to keep the required run rate in check as Australian bowlers struggled to find answers.
While Suryakumar orchestrated the carnage, Kohli played the second fiddle. At the halfway mark India needed 96 with eight wickets in hand.

Suryakumar soon brought his fifty as the duo plundered 15 off Adam Zampa's 13th over. Australia fashioned a comeback, ending Suryakumar's outstanding innings with India needing 53 off the last six overs.
Kohli, however, continued to go about his business, whacking Pat Cummins for a six in the very next over. He brought his first fifty of the series in 36 balls. Australia bowled some tight overs to keep themselves in the hunt.
But Hardik (25 not out) and Kohli slammed a couple of sixes but the latter was out leaving India in need of five runs from four balls.
