Australia beat England by 150 runs on Tuesday to win the third Test in Perth and reclaim the Ashes from their bitter rivals.
England were all out for 353 on the final day at the WACA Ground to hand the home side an unbeatable 3-0 lead in the five-match series.
It capped a remarkable turnaround for Australia, who went into the series just months after a 3-0 Ashes loss in England.
Despite a determined rearguard action — led by rookie English batsman Ben Stokes, whose maiden Test century frayed Australian nerves — the home team ran through the English tail after lunch to claim a famous victory.
The Australians had won the first two Tests in Brisbane and Adelaide and secured the urn when rejuvenated paceman Mitchell Johnson claimed his 23rd wicket of the series to remove Jimmy Anderson and end the England second innings.
Although the Ashes have been regained, Clarke said Australia were targeting a 5-0 win in the series as they seek to climb from fifth in the world Test cricket rankings.
Set a record 504 to win, England went to lunch on the final day at 332-6, needing 172 more runs with four wickets in hand and Stokes still at the crease. However, Australia turned the screws when spinner Nathan Lyon (3-70) picked up the wicket of Stokes for 120 in the third over after the break.
Good knock by Stokes
It was the end of a superb knock by Stokes, who showed up his more senior teammates by staying at the crease for 257 minutes and facing 195 balls, hitting 18 fours and one six.
His departure also ended a 40-run partnership with Tim Bresnan.
Lyon then picked up Graeme Swann for four, caught at short leg, as Australia closed in on victory.
Bresnan (12) was the next to go, brilliantly caught by a diving Chris Rogers at mid-off from the bowling of Johnson.
The match was over when Johnson (4-78) claimed his final scalp of the innings, with Anderson caught at short leg by George Bailey.AFP
