Australia beat India in the final hour of the fourth Test in Melbourne to take a 2-1 lead in the dramatic series.
India needed 340 to win at the start of the final day and looked on course to secure a draw when they reached tea time with just three wickets to spare.
But Rashibh Pant pounced on Mitchell Marsh on the boundary off Travis Head, the first of seven wickets to fall for 34 runs as they collapsed to 155 all out.
Pant (30) and opener Yashasvi Jaiswal, who was clearly displeased when the third umpire ruled he had given Pat Cummins to wicketkeeper Alex Carey for 84, provided the main resistance.
But no other Indian batsman reached double figures as they settled down to a 184-run defeat.
Scott Boland struck twice before Nathan Lyon ended the innings when he trapped Mohammed Siraj leg before as the last three wickets fell for five runs in three overs.

Cummins: One of the best tests I've been to
Australian captain and Test player Pat Cummins:
“What an amazing Test match, I think one of the best I've been in. All week the crowd was hilarious, and it was amazing to be a part of.
“Winning the toss, it wasn't easy on the first day, getting to a high 400 was great. We wanted to take India's win out of the equation. We had plenty of runs to play and as many helmets around the bats as we could.
“Steve (Smith's) amazing innings just showed how he bats on that wicket. He was brilliant, and some nice catches, sometimes that goes unnoticed in the slips.
“We've put a lot of work into our lower-order batting, how best to bowl to the opposition batsmen, but also how we can contribute with the bat. We were a bit behind the mark, so we thought: 'Bring Trav in, he can help us'. A very happy dressing room , we'll enjoy this before we get to Sydney.”
India captain Rohit Sharma:
“It's quite disappointing. It's not like we went in with the intention of giving up the fight. We wanted to fight until the end and unfortunately we didn't succeed.
“It will be difficult to judge only the last two games. If you look at the overall test match, we had our chances but we didn't take them. We had Australia 90-6.
“We know things can get tough but we want to play tough cricket from tough situations. I don't want to look at just one situation.
“We weren't good enough. I went back to my room and thought about what else we could have done as a team, but we threw everything we had. But they fought hard, especially that last-wicket partnership, which got us probably cost the game.
“We knew 340 wasn't going to be easy. We tried to set the platform and keep the wicket in hand in the last two sessions but they bowled well too. We wanted to go for the target but we didn't set the platform from our side. There are ways to win. in games, and we couldn't find ways to win games.”
