England endured a miserable day in Brisbane as Australia wrestled back control of the opening Ashes Test.
England - and Stuart Broad in particular - had dominated day one at the Gabba as they limited the hosts to 273-8 and they will have fancied their chances after wrapping up the innings for 295.
However Australia hit back in impressive fashion, with Mitchell Johnson, Ryan Harris and Nathan Lyon ripping the heart out of the England innings before David Warner and Chris Rogers piled on the pressure late on.
Although England lost Alastair Cook and Jonathan Trott cheaply, there was no sense of the drama that was about to unfold as the tourists reached 82-2.
A shocking collapse, though, saw England lose six wickets for just nine runs - and one stage it was even uncertain if they would avoid the follow-on.
Broad, England's second top scorer with a belligerent 32, helped ensure the tourists wouldn't have to bat again immediately. Yet that was scant consolation as England were dismissed for 136 - a deficit of 159 - on a pitch that has no real gremlins in it.
And with Warner and Rogers comfortably guiding Australia through the final 22 overs of the day to reach 65-0 at stumps for a lead of 224, the visitors now have a mountain to climb if they are to avoid a heavy defeat.
England had wrapped up the final two home wickets for the addition of just 22 runs, with Broad removing Harris to finish with 6-81 - the sixth best figures by a visiting bowler in Brisbane.
Brad Haddin was the last man out, falling six runs short of a century after he was caught short of his ground by Michael Carberry's throw from deep cover.
England had set about their first innings confidently enough as they survived the first 10 overs with few alarms.
However Harris once again accounted for captain Cook (13), getting the left-hander caught behind by Haddin. Trott also failed to last through to lunch, falling to what proved to be the last ball of the session as he nicked a short one from Johnson when attempting to flick to fine leg.
While two of England's more senior players fell cheaply, Carberry had looked solid during the morning session, only to then become completely becalmed after the break.
But while Kevin Pietersen was at the crease everything looked to be in hand. He had moved to 18 easily enough in his 100th Test appearance, only to then flick a leg-side half-volley from Harris straight to George Bailey at mid-wicket.
His departure sparked a quite astonishing turn of events that turned the tide in Australia's favour.
Opener Carberry (40) was undone by a good short ball from Johnson (4-61) that he could only fend off to Shane Watson at a wide first slip position.
Ian Bell, so often England's saviour during the summer series on home soil, perished for just five to Lyon, who then sent Matt Prior back for a first-ball duck. Both were taken at short leg by Steve Smith, his second catch only coming when he convinced skipper Michael Clarke to use the DRS.
The same fielder also pouched an outside edge from Joe Root's bat off Johnson's bowling, while Graeme Swann came and went without troubling the scorers, Bailey taking a simple bat-pad catch under the helmet.
Broad and Chris Tremlett guided England past the follow-on mark, however the return of Harris (3-28) broke their 19-run stand. Tremlett attempted to fend away a short delivery but he only succeeded in finding Lyon at leg gully.
Broad added some lusty blows late on before he became Peter Siddle's first victim - with Rogers taking the catch at deep mid-wicket as England registered their fifth lowest total at the Gabba.
And Australia's openers proved there are few issues with the pitch as Warner raced to 45 not out, while Rogers was unbeaten on 15 by stumps.
