England's bowlers hit back hard on day two of the fourth Ashes Test to reduce Australia to 111-5 at lunch.
The tourists - 3-0 down in the series - were skittled for 159 on Boxing Day but soon had a boost when Ricky Ponting mistimed a pull off Andrew Flintoff.
Matthew Hoggard then bowled Mike Hussey and Steve Harmison had Michael Clarke caught behind in his first over.
Opener Matthew Hayden rode his luck to make an unbeaten 52 but the morning belonged to England and their seamers.
It was just what Flintoff's men needed after another demoralising day on Monday.
The skipper and Hoggard were right on target from the off, causing Ponting and Hayden plenty of problems with a combination of probing lines and movement through the air.
A breakthrough duly came when Ponting tried to pull a wide one and holed out to Alastair Cook at mid-wicket.
Hayden, who might have been given out lbw to Hoggard on the first evening, continued to look uncomfortable against his clever variation.
The big left-hander saw drives fly just between short cover and mid-off and through the slips.
But Hoggard finally had his reward with the first ball after the drinks break when he comprehensively bowled Hussey, who had previously made scores of 86, 91, 61 not out, 74 not out and 103 in this series.
Things got even better for England when Harmison found bounce to have Clarke edging behind during an impressive wicket maiden.
Andrew Symonds, who has struggled to establish himself at this level, began unconvincingly.
He was beaten all ends up by an absolute pearler from Harmison, who then saw an edge bounce just short of Paul Collingwood at slip.
But he hung around to provide support to friend Hayden, who reached his fifty just before the break to remind England they still had plenty of work to do.
Another worry was the sight of Hoggard feeling his right side and grimacing towards the end of the morning.
