Demoralised England capitulated after tea against the home side's pace attack, losing seven wickets in 52 minutes on their way to being bundled out for 166 in 31.4 overs -- getting nowhere near the 448 target for victory.
It was the sixth time the beleaguered tourists had been skittled for under 200 in the series and the crushing defeat is expected to have major ramifications for English cricket just months after they beat Australia 3-0 in England.
Skipper Alastair Cook (7), Ian Bell (16) and Kevin Pietersen (6) all fell in the middle session as England limped to tea on 87-3 but it was carnage after the interval as four wickets tumbled in two overs with the tourists falling apart against inspired Australian bowling and fielding.
Michael Carberry (43) feathered Mitchell Johnson to wicketkeeper Brad Haddin just two balls after the resumption and three balls later debutant Gary Ballance was trapped plumb in front by Johnson for seven.
