Australia have won their first Ashes series since the 2006-07 whitewash, and England must now avoid the terrifying prospect of another 5-0 thrashing.
Here is the reaction from England and Australia greats from the past to defeat at the WACA...
Michael Vaughan, 2005 Ashes-winning captain: "England have been battered. It has been quite embarrassing."
Geoffrey Boycott, former England Test captain: "On paper, there is nothing to choose between the teams but one has got it significantly right in performance and planning. The other has cocked it up big time."
Glenn McGrath, former Australia Ashes winner: "There are a lot of negatives but with Carberry, Root and especially Stokes there are some positives. Mitchell Johnson produced some hostile, in-your-face bowling and he has been the stand-out difference in this series."
David Lloyd, former England coach: "There has got to be a reaction. The selectors, manager and captain must come up with something for the next game."
Ian Botham, former Ashes winner: "I'm disappointed I've not seen more fight and more guts from England. This is the Ashes."
Andrew Strauss, two-time Ashes-winning England captain: "England came into this series with fear of what might happen. Right from ball one we've seen a fearful England."
