Mitchell Johnson grabbed seven wickets with some fearsome fast bowling to skittle England for 172 on Saturday and give Australia a 398-run lead halfway through the five scheduled days in the second Ashes test.
After resuming day three at 35-1 in reply to Australia's 570-9 declared, England struggled to 116-4 at lunch. Johnson triggered the collapse after the interval and finished with 7-40 - including a spell of 5-12 in 18 balls.
Only Ian Bell (72 not out) and Michael Carberry (60) defied Johnson.
It was the third straight innings in this series that England has failed to reach 200, with Johnson's pace proving just as effective on the slower Adelaide Oval wicket as it was when he took nine wickets in Brisbane.
Australia did not enforce the follow-on.
