It took less than an hour for Australia to wrap up proceedings on the final day in Adelaide, securing a 298-run win in the fourth Test and with it a four-nil series whitewash.

Heading into Saturday's play, it was always a question of 'when' not 'if' the hosts would seal their fourth comprehensive victory. Ryan Harris ensured that early inroads were made when he drew Ishant Sharma (two) into having a dab at a delivery that moved away from him in just the third over, the edge was found and Brad Haddin did the rest.

Having provided stern resistance in the first innings, Wriddhiman Saha (three) offered little this time around, pushing forward at a fullish ball from Peter Siddle and edging to Haddin.

On a pair and having got three first-ballers in the series, Zaheer Khan (15) appeared a walking wicket but he would not go down quietly, letting off a few heaves before he topped-edge a pull off Ben Hilfenhaus to David Warner at short cover.

Only four bowlers got a go on the final day and in a turn that has mirrored the series, with all the bowlers chipping in, it was Nathan Lyon who ended the contest when he had Umesh Yadav (one) caught behind.

For Australia, the series could barely have been better, they were thoroughly dominant and there were many positives to take from the series. Michael Clarke led from the front with runs and Ricky Ponting showed there is still life in the old dog. On the bowling front one thing is clear - there are plenty of pacemen capable of doing the Baggy Green proud.

India on the other hand have many tough questions hanging over them. A clean out is surely needed and don't be surprised to see one or two retirements in the near future.
