The old enemies will lock horns again in the opening Investec Test in Cardiff on Wednesday, their first Test meeting since England were humbled 5-0 Down Under 18 months ago.
The Aussies are favourites to retain the famous urn, despite not having won a series here since 2001, but England seem to have found some momentum at the right time following the recent thrilling Tests and one-dayers against New Zealand.
And fast bowler Finn said: “We are desperate to win back those Ashes. We hate the fact that we lost them in Australia, it’s something we want to put right.
“These guys have a burning desire to stand on the podium at the Oval after the last Test and lift those Ashes in front of our home crowd.
“We’ve seen how much the home crowd have got behind us this summer. There has been a big turnaround in people’s attitudes to the England cricket team and we want to make them proud.
“They’ve got the form going into it after the last series. But we are playing in completely different conditions and you need some different skills to win a series in England.
“We have guys who play here every summer, they come here once every four years. Our own conditions and our own crowds will help us.
“It doesn’t matter who’s favourite, when we walk out at Cardiff it’s 11 versus 11.”
Finn himself is unlikely to be involved in Wales with Mark Wood expected to take the third seamer’s spot behind James Anderson and Stuart Broad.
But his mere inclusion in the squad is a minor triumph for the 26-year-old, who has not played a Test since the summer of 2013 and was deemed “unselectable” while on that doomed Ashes series later the same year.
So Finn is comfortable in his role as understudy and ready to step up to the plate when needed over the gruelling seven-week showdown.
“In my head I’m prepared to play, I’m getting ready to go out there and do battle on Wednesday,” he added.
“If I’m being realistic I am back-up to the guys who bowled so well in the New Zealand series, and I’m comfortable with that. It’s a long summer and things may happen.
“All I can do is look after my own game, make sure I am in good rhythm and keep doing everything I can so that if I do get the opportunity to play, I can do myself justice and help England win a game of cricket.”
