India maintained their 100 per cent record at the ICC World Twenty20 as Australia's miserable campaign continued with a 73-run defeat in Dhaka.
Already eliminated from semi-final contention, Australia went into the contest playing for nothing more than pride but had their woes compounded after being skittled for just 86.
A first win of the competition looked possible when India posted a middling total of 159-7, with Yuvraj Singh (60) providing most of the impetus towards the end of the innings.
But Australia's chase was all over inside 17 overs as Ravichandran Ashwin returned figures of 4-11 amid a dramatic batting collapse
India had already sealed their progress to the semi-finals with three successive wins but did not make the best of starts on Sunday and had to recover from 66-4 after being put in to bat.
Yuvraj did the majority of the repair work alongside skipper Mahendra Singh Dhoni (24), as they combined in an 84-run stand from 42 balls.
Yuvraj hit four sixes and five fours in his 43-ball innings but he and Dhoni both fell inside the final two overs during which India only added 12, leaving a target that appeared well within the reach of Australia's batting line-up.
But Australia's top order again failed to fire, David Warner (19) and Glenn Maxwell (23) being the only players in the top six to reach double figures before Ashwin removed both after reckless strokes.
In amongst the collapse Shane Watson (1) had another failure, being bowled attempting to late-cut Mohit Sharma to leave him with just seven runs in the tournament.
Watson was the leading runscorer at the previous World Twenty20 in 2012, when Australia reached the semi-finals.
Ashwin fittingly ended the match when he had young Australia leg-spinner James Muirhead (3) caught behind by Dhoni.
Australia now need to beat Bangladesh in their final match if they want to avoid a winless campaign while India are certain to finish top of Group 2.
