Australia completed victory by an innings and 37 runs over India to earn a series-clinching success in the third Test at Perth.

Ben Hilfenhaus claimed three wickets in a single over shortly after lunch as Australia took the final four wickets without conceding a run to seal the win early in the afternoon session on day three.

Virat Kohli had kept the Australians' victory push at bay when he batted through the morning session, but after Hilfenhaus' stunning triple-strike, he fell to Peter Siddle in the fourth over after lunch as the hosts opened a 3-0 lead in the four-Test series.

Hilfenhaus finished with figures of 4-54, after being on a hat-trick during an over that saw him have Vinay Kumar and Zaheer Khan caught by Michael Clarke at first slip.

The Tasmanian narrowly missed the hat-trick but had Ishant Sharma caught at short leg two balls later before Siddle removed Kohli, who provided the one bright spot for India with his Test-best 75, as the tourists were bowled out for 171.

India never recovered after a disastrous first day when they were rattled out for 161, before David Warner smashed the equal-fourth quickest Test century from 69 balls.

Their veteran top-order folded in both innings, as they failed to deal with a fast-paced WACA Ground wicket, that Australia's four-pronged pace attack thrived on.

Defeat was also India's seventh consecutive reverse on away soil and leaves them facing another whitewash tour after their 4-0 reverse in England in the summer.
