England were skittled out for 251 to concede a hefty first-innings deficit before Australia piled on the runs to stretch their lead on day three of the third Ashes Test in Perth.
It was another dismal collapse from England as the tourists imploded from 180-4 overnight to 251 all out as Peter Siddle and Ryan Harris each took three wickets.
A hopeless day was made all the worse for Alastair Cook's side after Stuart Broad was struck on the foot by a Mitchell Johnson yorker and had to depart for a scan on the injury without bowling a ball in the second innings. He will not bowl in the remainder of the match.
David Warner then compounded the tourists' misery further with a brutal 112 off just 135 balls while Chris Rogers added 54 as Australia inched closer to regaining the Ashes with an enormous second-innings lead and seven wickets still in hand.
England 190-5 - Bell is trapped lbw as Harris gets a full delivery to nip back in and he goes for 15 after Australia successfully review the initial not out decision.
England 198-6 - Johnson pitches one right up to Stokes, who is lured into a drive and gets an edge through to Haddin to depart for 15 after a gutsy resistance.
England 207-7 - Prior's wretched run of form continues as he goes to pull a short ball from Siddle and gets a thin bottom edge through to Haddin to fall for eight.
England 229-8 - Broad is trapped flush on the toe in front of middle stump by a vicious Johnson yorker and he could well have suffered a foot injury as he goes for five.
England 233-9 - Harris hits a good length and Bresnan is caught in two minds on the crease as he edges behind to Haddin to go for a doughty 21.
England 251 all out - Siddle wraps up another hapless showing with the bat from England as Anderson goes for two, spooning a simple catch to Bailey at short leg.
Australia 157-1 - Rogers slaps a full and wide delivery from Bresnan straight to Carberry at point to depart for 54 in soft fashion.
Australia 163-1 - Warner drills a full ball from Swann past point for four runs and leaps into the air to celebrate another brilliantly belligerent century.
Australia 183-2 - Stokes shuffles back a few yards at mid on to take a simple catch as Warner miscues a slog sweep off Swann and goes for a brilliant 112.
Australia 223-3 - Stokes gets a full delivery to nip back in off the seam and bowl Clarke, who goes for 23 as he misses an attempted straight drive.
Australia 235-3 - Watson (29) and Smith (five) lead Australia to stumps with seven wickets still remaining and a lead of 369 runs on the board.
Warner, Haddin and Clarke have scored more runs in the series between them than the entire England team.
Warner now averages 111 for the series after his fifth Test 100 and his 2nd at the WACA.
It was the first 100+ opening partnership by Australia at home since 2002 with Matthew Hayden and Justin Langer's effort 27 innings ago.
Warner struck the 100th six conceded by Swann in Test cricket.
TALKING POINT OF THE DAY
Do England now have to make wholesale changes? Surely England cannot go into the fourth Ashes Test at Melbourne with the same players that are consistently collapsing in disastrous fashion, but continuity has been the key buzzword under Flower's management. Should the tourists make a string of changes to their underperforming side for the Boxing Day Test with the Ashes almost certainly gone by then?
QUOTE OF THE DAY
Geoffrey Boycott: "This was one of the worst days I can remember from England in a long time. The wheels are off. The brains are scrambled. I can see a five-nil drubbing."
