Virat Kohli's dominant India reinforced their status as the world's number one team by winning a historic first-ever series in Australia after play in the final Sydney Test was abandoned due to rain.
Australia were still 316 in arrears when the match was called off as a draw, leaving India with a 2-1 triumph after wins in Adelaide and Melbourne. Australia won in Perth.
It is the first time they have managed the feat since they began touring Australia in 1947-48.
India had ripped through the Australian tail in Sydney on day four, when bad light and rain allowed only around 100 minutes of play, bowling the hosts out for 300 in reply to their own huge 622 for seven declared.
Australia then suffered the indignity of being forced to follow on at home for the first time in 30 years as Kohli twisted the knife.
Only four overs of their second innings were possible, with Marcus Harris not out two and Usman Khawaja unbeaten on four before the match was called off.
"I want to say I've never been more proud of being part of a team, than this one right here," said Kohli.
"The boys make the captain look good. By far, this is my biggest achievement. It's at the top of the pile."
Australia skipper Tim Paine paid tribute to India.
"Have to tip our hat to India, we know how tough it is to win in Australia so congrats to Virat and (coach) Ravi (Shastri) because it's a huge achievement," he said.
"Disappointed, definitely over the last two Tests. We had our chances in Adelaide, in Perth I thought we played some good cricket, but in Melbourne and Sydney, we've been outplayed."
India were off to the best possible start by winning the tight opening Test in Adelaide by 31 runs – their first Test win in Australia for a decade.
The victory was built on Pujara's heroics in both innings while wicketkeeper Rishabh Pant took a world record-equalling 11 catches.
Australia bounced back in Perth to level the series, winning by 146 runs.
It was a huge relief for the home side, having not won a Test since the ball-tampering "sandpapergate" scandal that rocked international cricket last March.
But another Pujara century in Melbourne set the visitors up for a big first innings total and when Australia capitulated in reply to 151 all out, the scene was set for India to take a stranglehold on the series coming into Sydney.
Aside from man-of-the-series Pujara, a big part of their their success in Australia has been executing their bowling plans to deprive the Australian batsmen of playing their shots.
India's bowling coach Bharat Arun said the successful strategy stemmed from mistakes made last year in series against South Africa and England.
"I thought those two tours were a great experience for us and that has helped us immensely to come and do well in Australia," he said.
"We said that to be successful in Australia, we need to make sure that we need to take the cut and the pull out of the Australian batsmen and then focus the attack on our strengths, so that's exactly what we did."
While virtually all of Australia's leading batsmen got off to a decent start, none converted them into a big innings, underscoring how much they miss the banned Steve Smith and David Warner.
Harris' 79 in Sydney was the highest any of their batsmen managed the entire series, making it the hosts' first four-Test home series without scoring a century in their history.
