Glenn Maxwell hit a half-century as Australia edged India by three wickets in a thrilling last-ball finish at the first T20I on Sunday.
Pat Cummins hit a four and took two runs to complete a nervous 127-run chase after his fellow paceman Nathan Coulter-Nile restricted India to 126-7.
Maxwell, who made 56, put together 84 runs with D'Arcy Short for the third wicket to put Australia on course before Jasprit Bumrah hit back with three wickets.
But the day belonged to Coulter-Nile who returned figures of 3-26 in his four overs, receiving the man of the match award.
KL Rahul, who hit 50, forged a 55-run second wicket stand with skipper Virat Kohli to gave India a brisk start but the hosts lost momentum after losing three quick wickets.
