Australia needed less than an hour to wrap up the last four England wickets to move 2-0 up in the Ashes series with three to play.
Australia won the second Test in Adelaide by 218 runs, to go with their 381-run victory at the Gabba.
Their push for victory received an scarcely believable boost in the first over today when Stuart Broad was out hooking Peter Siddle.
The home side then moved to within two wickets of wrapping up the win when Grame Swann fell to Ryan Harris to leave them on 8-293.
And while Matt Prior gave it a bit of biff to take the tourists past 300, he also went to the hook shot for a well-made 69.
Monty Panesar was last man out as Siddle and Harris finished with seven wickets between them.
After early morning rain had delayed play by just 10 minutes, England resumed their second innings at 6-247, still 283 runs behind and with Australia needing just four more wickets on the final day to go 2-0 up in the five-Test series.
Broad (29) showed immediate intent by hooking Siddle for six over the deep square leg boundary.
But incredibly he tried the same shot again next ball and only succeeded in finding Nathan Lyon in the deep.
It was the latest example of poor judgement from England's shell-shocked batsmen.
The wicket signalled some increased aggression from Prior, who ended a barren run with a well-made fifty as he and Swann looked to delay the inevitable.
But in Harris' first over Swann (7) dangled out the bat and edged straight to Michael Clarke at second slip.
With only James Anderson and Panesar left, Prior went for broke and smashed a few more boundaries before picking out Harris to give Siddle his fourth wicket.
