Zampa was on a hat-trick and single-handedly conjured a collapse of 3-15, including the prized scalp of MS Dhoni for a golden duck.
Asked to bat first, the hosts were bowled out for 250 runs in 48.2 overs.
Promoted ahead of experienced campaigners like M.S. Dhoni and Kedar Jadhav who led India to victory in the first match at Hyderabad, Vijay Shankar exhibited skill and power to virtually dominate a fourth-wicket partnership with skipper Virat Kohli after Australia, opting to field, made inroads. Kohli and Vijay appeared to be in so much control that the latter's exit, a run-out backing up when the captain's drive was deflected onto the stumps by Zampa, was a genuine surprise in both its eventuality and its manner.
India got off to a poor start losing Rohit (0) cheaply but Kohli staged a lone battle to single-handedly steer India to a respectable total on the board. On his side's batting, he said, "I'm more proud of our second innings than our first".
Bumrah was once again supreme, critically claiming two wickets for just one run in the 46th over of the innings and then cornering Stoinis into playing out another over worth one in the 48th, while Kuldeep's three wickets counterbalanced greater expense than usual.
Jadeja (21) came in at a very crucial time when India were placed precariously on 171/6. Not typical of the kind of pitches you get here does not look like it will bounce much.
In a fluctuating second ODI that provided a nail-biting climax, Kohli, the India captain, turned to Shankar's medium pacers for the final over because his more senior bowlers had completed their allocations. "We got 30s and 40s, they got a hundred, and that was the difference", he said. Maxwell lasted only briefly before his pull shot was tunnelled under by Kuldeep, but Handscomb formed another effective stand with Stoinis, to take the game deep.
Finch described Stoinis' innings as brilliant in the post-match ceremony, lamenting how nobody in Australia's top order posted a big score. "The game ebbed and flowed the whole day".
