Comprehensive losses in the first two Tests had put Andrew Flintoff's men under pressure ahead of the third encounter.
Despite little separating the teams after the first innings, Australia showed their superiority after and wrapped up the victory and series early into the afternoon session on day five.
After folding under the pressure in Brisbane and Adelaide, the visitors were eager to not relinquish the Ashes at the earliest opportunity but could only produce 215 in response to the hosts' total of 244 first up.
On 265 for five, England needed heroics from Kevin Pietersen and Flintoff and while both made half-centuries, it was not enough.
Shane Warne made the breakthrough when he bowled the away skipper and finished with four for 115 to dismiss England for 350 just after lunch, with Pietersen stranded on 60 not out and the Ashes back in Australian hands.
Further defeats at Melbourne and Sydney saw head coach Duncan Fletcher and his players suffer a 5-0 series whitewash to lose possession of the urn in embarrassing fashion.
