Day three of the third Test in Perth may well go down as the day on which Australia finally pushed England's Ashes defence past the point of no return, closing it some 369 runs ahead.
England could only muster 251 in their first innings, replying to Australia's 385, and by stumps the home side had almost as many runs again for the loss of just three wickets.
David Warner cracked 112 and Chris Rogers 54 to compound England's problems, and with the pitch already developing large cracks, they can again expect to be asked to bat for more than four sessions to save the game.
And as if being completely outplayed wasn't enough punishment on another scorchingly hot day, they lost Stuart Broad to a foot injury and he will now bowl again in the game, although he will bat in England's second innings if at all possible.
England resumed on 180 for four and needed to get as close as possible to Australia's score to stay in the game, but managed to add just 71 more runs.
Ian Bell (15) and Ben Stokes (18) made little progress from their overnight scores and thereafter it was fits, starts and body blows for England.
Broad was struck on the foot by Mitchell Johnson to be trapped in front for five and the blow has effectively ruled him out of the rest of the match.
Matthew Prior made eight, Tim Bresnan 21, Graeme Swann was unbeaten on 19 and James Anderson fell for two as Australia mopped up England's lower order with a minimum of fuss, needing less than 20 overs to finish them off.
Peter Siddle ended with three for 36, Ryan Harris three for 48, Johnson two for 42, Nathan Lyon one for 39 and Shane Watson one for 48.
With a lead of 136 already, Australia set about their goal of putting the game beyond England's reach with gusto.
Warner was in superb form, hitting 17 fours and two sixes in a whirlwind 140-ball innings of 112 while Rogers made 54 in 135 balls - the perfect foil for Warners flashing blade at the other end.
Their combination proved mighty effective and together they added 157 before Rogers cut Bresnan to Michael Carberry at point and Warner fell soon after, caught in the deep by Stokes off Swann.
There was be no fairytale innings for Michael Clarke in his 100th Test as he was bowled by Stokes for 23, but Australia remained in complete control with Watson and Steve Smith unbeaten at stumps on 29 and five respectively.
Smith scored a century to set up Australia's first innings score before England fought back on day two, only for Australia to close the stronger - on day three they carried on from where they left off and did not allow England back into the contest at all.
