Even a change of format hasn't been able to stop Australia's batting collapses, with India easily chasing down a reduced target in the rain-curtailed first T20 international.
The visitors lost 7-69 in Ranchi as they limped to 8-118 before weather ended their innings with eight balls remaining.
After a delay of almost two hours, India were given six overs to chase 48 which they hunted down with three balls to spare.
Rohit Sharma made 11 off seven balls before Nathan Coulter-Nile found a way through his defences to claim the only wicket of the innings.
Indian skipper Virat Kohli (22 off 14) and opener Shikhar Dhawan (15 off 12) did the rest, cruising to 1-49 after smashing three boundaries each.

Glenn Maxwell couldn't play himself into form, struggling for his 17.
Maxwell pulled a long hop straight to mid-wicket off Yuzvendra Chahal who has claimed his wicket in all four of the Victorian's innings on the tour.
Australia's middle order again failed when they were needed, mimicking their efforts in the ODIs.
Travis Head (nine), Tim Paine (17) and Nathan Coulter-Nile (one) completed the sextet of Australians who were bowled.
