Before The Ashes began, the odds for an Australian 5-0 series whitewash were 50/1. Now they are available with Ladbrokes at 7/2 to win every Test.
Already 2-0 up and with England looking in disarray, the odds on an Australian series win have been slashed to 1/12.
England are now 25/1 to win the series.
"The odds of an Aussie whitewash have collapsed quicker than England's batsmen," Ladbrokes cricket betting expert Jessica Bridge said.
"Before the series both teams were backed heavily to win 5-0, and despite the short price punters are still piling into Australia at 7/2."
Ladbrokes also think that Michael Carberry will not feature in the next Ashes contest in 2015, making him a 3/1 chance to start the first Test in 18 months.
Meanwhile, Alastair Cook (1/10), Joe Root (1/10), Ian Bell (1/8) and Kevin Pietersen (1/2) are expected to still be around when the Australians next land on English soil.
Cook is 1/5 to still be in charge of the side with Stuart Broad a 5/1 chance and Joe Root at 10/1 to have taken the reins before then.
