India beat Australia in Delhi by six wickets to record a whitewash over the tourists.
India completed their victory over Australia in four days to confirm a series whitewash and a poor tour for the visitors.
The Australians were bowled out for 164 in their second innings with bowler Peter Siddle once again top-scoring for the tourists with 50.
It had been a good start to the day for Australia with spinner Nathan Lyon recording career best figures of 7-94 whilst limiting the Indians to 272 all-out.
Lyon dismissed danger-men Virat Kohli and Sachin Tendulkar to give his side hope of avoiding defeat.
Yet Australia once again failed to perform with the bat as none of their top order made an impression. The series finished with Michael Clarke being the only Australian to make a century in any of the four Tests.
Indian bowler Pragyan Ojha spearheaded his side’s bowling onslaught as opener Glenn Maxwell was out for eight and stand-in captain Shane Watson made just five.
Australia did well to even make 164 as they were 94-7 at one point, but Siddle’s 45-ball half-century made the final total slightly more respectable.
India made light work of their 155 run target however as Cheteshwar Pujara hit the winning boundary at the end of his unbeaten 82.
Defeat in India is the first time the visitors have endured a 4-0 whitewash since losing to South Africa in 1970.
Australia will now have some time to reflect on their disastrous tour of the sub-continent as they prepare for back-to-back Ashes series in 2013 – the first of which starts in England in July.
