Ponting, who lost the Ashes for a second time as captain in a 2-1 series defeat in England last year, said the Australians had learnt from their mistakes and were a better side than that which played in the last Ashes contest.
Australia have slipped to fourth, narrowly ahead of England, in the Test rankings after their 1-1 drawn Test series against sixth-ranked Pakistan in England last month.
But Ponting, who met Cricket Australia officials in Melbourne on Monday to map out preparations for the November-January Ashes series, is undaunted.
"It's absolutely possible. There's no reason why not," Ponting told reporters at the Melbourne Cricket Ground when asked about a 5-0 Ashes sweep.
"It's all in our hands. It's how well we play and how well we take charge of different situations,” he said. "We've learnt from a lot of the mistakes that we've made. There's no doubt we made some mistakes in the last Ashes series in England that probably at the end of the day cost us the series.”
"We know now that we're a more experienced and probably a better team now than we were then,” Ponting asserted.
"I've got confidence in the squad of players that we've got that they are going to be good enough to win an Ashes series."
Ponting said England's form in winning the opening two of four Tests this month against Pakistan was impressive but added the tourists would offer few surprises this summer.
"We'll have a different set of conditions and a different ball when they come out here and I'm sure our guys will equip themselves really well,” he said.
The opening Ashes Test begins at Brisbane's Gabba ground on November 25.
