India's 19-Test unbeaten run was emphatically ended as Australia beat them by 333 runs in the first of a four-match series.
Australia had a first-innings lead of 155 runs after bowling their hosts out for 105 in Pune.
The tourists scored 285 in the second innings, setting India a record target of 441 to win. However, India were all out for 107 inside three days.
On a pitch where they were given no chance, the two Steves in the team – Smith and O'Keefe – turned in performances of the highest quality to dump India to their first defeat since August 2015, and first at home since December 2012.
O'Keefe was the wrecker-in-chief in the first innings, having taken six wickets during an incredible seven-wicket collapse by the Indians. The left-armer was at it again on Day 3. He added to his six wickets by taking another six wickets for 35 runs (same as in the first innings) as India collapsed to another embarrassing total of 107-all out and were dealt their second heaviest defeat at home in terms of runs.
The Indians were under immense pressure, facing the record chase of 441. It was 'Mission Impossible' on a landmine of a pitch. Australia had spin on from both ends predictably early and it didn't take long for the cookie to crumble.
Murali Vijay looked tentative at the crease, failing to move his legs much and paid the price. O'Keefe, who had started bowling from the Hill End, where he had had all the success in the first innings, caught Vijay LBW to inflict the first damage. KL Rahul followed in the very next over, trapped on the backfoot to one spinning back in sharply. Along with these two dismissals, India lost both their reviews for the innings as well.
Virat Kohli, on whom most of the hopes rested, got off a pair with a confident flick to the leg side. He got himself to 13 off 36 balls before he missed a ball that went straight on from O'Keefe and shouldered arms. The off stump went to ground, and so did the Indians' hopes. Ajinkya Rahane adopted an aggressive approach and got himself to 18 off 21 before tamely chipping O'Keefe to Lyon at cover. When Ashwin became the fifth wicket to fall, again LBW to O'Keefe, the question turned from 'Can India pull it off?' to 'Can India at least take the game into the fourth day?'
As it turned out, they couldn't. O'Keefe wouldn't let them. He picked up the wickets of Wriddhiman Saha and top-scorer Cheteshwar Pujara (both LBW) to leave India crawling on all fours at 100 for 7.
Nathan Lyon helped himself to a couple of wickets as Ravindra Jadeja and Ishant Sharma lost their wickets cheaply. Every ounce of a fight had disappeared from the Indian team, and when they manage to crawl past 105, their first innings score, it even evoked a sarcastic cheer from the media contingent.
Australia's massive second innings lead of 441 runs was thanks to a breathtaking knock by Steve Smith. The Australia captain was dropped as many as four times, but played a truly spectacular knock in between those gusts of luck to slam a sensational hundred. On a tough track, Smith batted with assurance, lightning quick feet and an awareness for gaps that was almost too good to be true. He was able to counter even the most threatening spinners on the most threatening pitches.
Resuming the innings at 143 for 4, Australia lost Mitchell Marsh early. Smith, however, controlled the proceedings with some expert batting to snuff out any hopes of a fightback from India. With Matthew Wade and Mitchell Starc giving him decent company, he was able to push Australia into a position from where they could not lose. As it turned out, they had plenty in the tank, and India none in theirs for a fight.
Brief scores: Australia 260 (Matt Renshaw 68, Mitchell Starc 61; Umesh Yadav 4-32) & 285 (Steven Smith 109; Ravichandran Ashwin 4-119) beat India 105 (KL Rahul 64; Steve O'Keefe 6-35) & 107 (Cheteshwar Pujara 31; Steve O'Keefe 6-35) by 333 runs.

Ireland are aiming to play their first Test in 2018, according to Cricket Ireland chief executive Warren Deutrom.
The International Cricket Council (ICC) said earlier in February that the Irish would gain Test status this year, and that they could play their first match before then.
"There are no plans to play Tests in 2017 - we are looking towards 2018," Deutrom told BBC Sport.
"I don't see any reason why that can't happen. I'd be surprised if we didn't."
The ICC's plans come after a lengthy debate over the future of Test cricket, including how to spread the game and give each series more context. The agreed solution is for a nine-team Test league, running over a two-year cycle - starting in 2019 - with every side playing each other once.
Three more teams - probably current Test side Zimbabwe and likely newcomers Ireland and Afghanistan - would be guaranteed a schedule of matches over the same two-year period.
The ICC said it will make a decision on granting Test status to Ireland and Afghanistan at its next board meeting in April, with that likely to be ratified at the annual general meeting in June.
It is thought there would be no barrier to both sides being able to play Test cricket immediately, but the schedules of other nations would probably mean a wait is necessary.
Deutrom admitted that, ideally, a first Irish Test would be at home, but that it would be difficult to turn down a "dream" scenario of an away match against England.
Even then, finding space in England's summer would be incredibly difficult, with Pakistan and India set to tour in 2018.
England's future programme could be linked to that of the Irish, with the ICC expressing its desire for teams that tour the country to also play at least one Test against Ireland.
Ireland first announced plans to gain Test status in 2012, a year after earning a famous victory over England at the 2011 World Cup.
They had already beaten Pakistan at the 2007 tournament and, in 2015, beat West Indies and Zimbabwe before narrowly failing to qualify from the group stage.
In October, Ireland's Inter-Provincial competition became the first domestic tournament outside of a Test nation to be granted first-class status.

Pakistan Super League (PSL) Chairman Najam Sethi on Tuesday announced that PSL will be using the decision review system (DRS) in the playoff matches, becoming the first T20 league in the history of cricket to use the review system.
The PSL chairman made the announcement through his official Twitter account saying, "Another first from HBL PSL. DRS to be used in the playoff matches."
The decision to implement DRS comes after umpires were scrutinised for making poor on-field judgements multiple times in the tournament.
Under the DRS system, both sides are allowed a limited number of unsuccessful challenges before they are barred from requesting a referral for the remainder of an innings.
But, in order to not delay the game, they must make it clear within a matter of seconds of the umpire's original verdict whether they wish to call on DRS.

British police announced Thursday a third suspect had been arrested in connection with their investigation into international cricket spot-fixing.
A statement issued by the National Crime Agency said officers had arrested a British man in his thirties this morning in the Sheffield area (in northern England) as as part of its investigation into the spot-fixing of cricket matches.
He was later bailed pending further inquiries.
Two men, also in their 30s, were arrested by NCA officers on February 13 and were bailed until April. Earlier this month, amid a corruption probe involving players in the Pakistan Super League, the NCA said they were “working closely” with the Pakistan Cricket Board and International Cricket Council's anti-corruption units.
Saturday saw Pakistani cricket officials charge Sharjeel Khan and Khalid Latif for spot-fixing in a corruption probe that threatens to undermine the PSL.
The pair, suspended after being accused of meeting a suspicious person linked to an international betting syndicate, could face up to a life ban from international and domestic cricket under Pakistan Cricket Board corruption rules.
Another former player Nasir Jamshed was also provisionally suspended over allegedly influencing the two players. Jamshed was reportedly arrested in London last week but was granted bail until April.
Both Sharjeel and Latif have denied any involvement in the alleged corruption.
The PSL, a five-team tournament, is largely being played in the UAE because of security concerns although Lahore is the scheduled venue for next month's final.
