Steve Smith steered Australia to another strong first innings total on day two of the Boxing Day Test with India in Melbourne.
The stand-in skipper became the first Australian to score centuries in each of his first two Tests leading the side, as he made a personal-best 192 to steer Australia to 530 all out.
The total seemed unlikely when the hosts began day two on Saturday at 259-5, but Smith - who began the day on 72 - Ryan Harris (74) and Brad Haddin (55) boosted their score.
In reply, India reached 108-1 at stumps - with Murali Vijay (55) and Cheteshwar Pujara (25) the unbeaten batsmen after Shikhar Dhawan (28) fell to Harris (1-19).
Earlier, Haddin got Australia's fast scoring going - crunching six boundaries in four overs as he raced to his half century.
The wicketkeeper produced some unorthodox shots, and took one Mohammed Shami (4-138) over for three fours as he took to the attack.
Shami got his revenge as Haddin edged though to fellow wicketkeeper MS Dhoni, but the damage was not done as Smith went on to put together a 50-run stand with Mitchell Johnson (28).
It should not have been such a healthy seventh-wicket stand, though, as a run out chance was wasted with Johnson on one.
The left-arm quick was stranded but Shami was not standing by the stumps to whip the bails off, so when the throw missed the stumps, the danger was averted in an embarrassing waste for the Indians.
Johnson's eventual departure - stumped off the bowling of Ravi Ashwin (3-134) - only brought Harris to the crease, and the Queensland quick produced a career-best batting performance.
Eight fours and a six came off Harris' bat in his 88-ball knock, as he and Smith put on 106 for the eighth wicket as the frustration grew for Dhoni's men.
Smith selflessly abandoned the safer option to nurture himself to a maiden double-century, instead choosing to slog - and he was bowled by Umesh Yadav (3-130) trying to play a 'ramp' shot to end Australia's innings.
Harris and Smith were not done tormenting the Indians yet, as they combined for their only wicket.
The paceman found the edge of Dhawan, and the skipper got down low to complete a tough catch at second slip.
Vijay, meanwhile, continued his hot form this series, taking his tally in Australia to 378 runs at 94.5, and he will look to further eat into India's sizable deficit on Sunday.
The Indian opener is second only to Smith (567) in runs scored this series.
