Virat Kohli has secured the Border-Gavaskar trophy and is smelling blood as he hunts India's maiden Test series win in Australia, an "obsession" that is driving the skipper and billions of fans.
India are confident and far from complacent after defeating Australia by 137 runs in the third Test.
They will take a 2-1 series lead to the SCG, where the final Test starts on Thursday.
Melbourne's morning rain on day five provided more resistance than some of Australia's batsmen but play finally started at 12.55pm on Sunday.
India required just 4.3 overs and a tick over 20 minutes to claim the required two wickets, triggering wild scenes from Kohli and India's supporters.
Jasprit Bumrah dismissed Pat Cummins to finish with man-of-the-match figures of 9-86, while Nathan Lyon was undone by an Ishant Sharma bouncer as Australia were rolled for 261 in pursuit of a venue-record target of 399.
"We're not going to stop here ... the job is not done," Kohli vowed.
"This has only given us more confidence to go to Sydney and play even more positive cricket.
"You have to give everything that you have to win a series ... to win a series away from home, it has to be an obsession.
"Hats off to the whole team for sticking together, believing in themselves and being obsessed."
Kohli copped plenty of criticism, including from Indian icon Sunil Gavaskar, for losing in Perth and making three changes to his XI for the Boxing Day Test.
"Once you are obsessed, changing your decisions according to opinions is not an option," Kohli said.
"We haven't changed our mindset regardless of who said what.
"Nothing is going to distract us from winning that last Test. We've never been in this position, we've worked really hard."
India have failed to win 11 previous Test series in Australia, a barren stretch dating back to when they were crushed by Don Bradman's side in 1948.
But the tourists, having exposed Australia's batting woes in clinical fashion throughout the MCG match, now have all the momentum.
Tim Paine, who admitted changes to the batting order and XI were possible after the lopsided loss, insisted his top six could find form and level the series in Sydney.
"We were outplayed and India deserved to win this Test," Paine said.
"It's inexperience. It's pressure. It's India's bowling attack being probably as good as probably most of these guys have ever faced.
"We're under no illusions we've got to work really hard."
Cummins, who pushed the third Test into a fifth day with his career-best knock but was dismissed for 63 on Sunday, declared Australia were desperate to avoid an ignominious series loss after being "outplayed" at the MCG.
"We can go 2-all in Sydney. That'd be a pretty good result against the No.1 team in the world. We are desperate not to lose ... really determined," Cummins said.
