First Test, Perth, day four:
Australia 381 & 361-5 dec; Pakistan 179 & 72
Australia bt Pakistan by 491 runs
Glenn McGrath took career-best figures of 8-24 as Australia raced to a 491-run win over Pakistan in the first Test.
Pakistan began the fourth day chasing 564 for victory but were dismissed for just 72 as they succumbed to the paceman on Perth's lively Waca pitch.
McGrath's figures are the best for an Australian against Pakistan and the second best all-time bowling figures for an Australian.
The next Test between the two sides starts on Boxing Day in Melbourne.
As daunting as Pakistan's task was, few would have expected the side to collapse in such dramatic fashion.
The visitors got off to the worst possible start when Salman Butt was caught in the gully by Matthew Hayden off McGrath for nine.
McGrath then picked up the wicket of the dangerous Younis Khan two overs later, who was caught by Shane Warne at first slip for 17.
Australia wicket-keeper Adam Gilchrist then got in on the fun, taking a catch from Abdul Razzaq's flick off the bowling of McGrath.
Captain Inzamam-ul-Haq, who had complained of a back problem, went for a duck thanks to the same combination.
McGrath had Kamran Akmal snapped up by Michael Clarke at fourth slip before Yousuf Youhana succumbed to a bouncer by the same bowler and was caught behind.
Seamer Michael Kasprowicz then took two for four to prevent McGrath claiming all 10 wickets.
McGrath, though, came back to claim his eighth victim when he had Shoaib Akhtar caught at mid-off by Darren Lehmann for one.
In virtually any other contest, McGrath's heroics would have earned him the man-of-the-match award, but that honour went to batsman Justin Langer, who scored 191 and 97 in his two innings.
