Australia captain Ricky Ponting was thrilled by the way his team had responded when put under pressure in the Champions Trophy final.
Australia celebrate as they take another wicket in Mumbai
A furious onslaught from player of the tournament Chris Gayle took West Indies to 49-0 after five overs.
But Australia cruised to victory by eight wickets after Nathan Bracken had triggered a Windies batting collapse.
Ponting said: "The bowlers did a terrific job when our backs were to the wall. Nathan was outstanding."
The first Australian captain to win the Champions Trophy in its fifth edition, Ponting added: "It's a great feeling to win a tournament like this - it's the one we haven't won and full credit to our guys.
"We've worked hard on specific things and it's come through in our performances.
"We had our backs to the wall after losing our first game but when the big games have come around we've managed to perform.
"The young guys in the side are improving, so we couldn't be happier. We've got a good mix of youth and experience and that's what you need."
For a few of us it might be our last Champions Trophy and it was a burning desire to win this trophy before the summer starts
Asked whether the tournament win might provide a springboard for Ashes glory, Ponting responded: "It doesn't hurt, that's for sure.
"We've got some big cricket to play when we get back to Australia but first we're going to enjoy what we've achieved in the last month."
Damien Martyn, whose unbeaten 47 gave him 241 runs in the tournament, said West Indies could have made the match more competitive with a few more runs.
"The wicket was a bit slow but it was turning at the end, so if they'd posted a better total it would have been interesting," he said.
"You need a bit of experience. It was hard to bat in most of these games and we needed to draw on that experience as much as we could.
"Having played in Indian conditions before and facing spinners on these wickets helps you."
Australia did lose two early wickets in their run chase after West Indies had collapsed to 138 all out, and there was some tension in the dressing-room at that point.
But Martyn and Shane Watson ultimately guided the Aussies smoothly to an eight-wicket win.
My goal was to get through to the end and it's one of those dreams, hitting the winning runs for your country
Martyn said: "When you lose a couple of wickets early you get a bit nervous.
"For a few of us it might be our last Champions Trophy and it was a burning desire to win this trophy before the summer starts.
"We have been wanting to win it for a long time and have played badly in past ones."
Man-of-the-match Watson, (57 not out and 2-11) said: "I've loved the opportunity of batting at the top order.
"It's easy to set a good platform with so many good players coming in down the order.
"There are so many legends of the game playing in our team so us youngsters are extremely lucky to be abe to learn from these guys.
"It's been a good challenge and to be able to chip in with a few wickets as well and contribute to the team's victory as well is a big thing.
"My goal was to get through to the end and it's one of those dreams, hitting the winning runs for your country."
