Victorious Australia captain Pat Cummins revelled in his side's World Cup victory over hosts India, capping a remarkable year by reaching "the top of the mountain."

Australia arrived in India as the underdogs, with the home team having a perfect record of 10 wins on their way to the final. The visitors also had to contend with a 110,000-strong partisan crowd.

Despite having the tournament's top scorer in Virat Kohli and leading wicket-taker in Mohammed Shami, India was unable to match Australia's ability to perform well in knockout cricket.

Travis Head took the starring role with a brilliant 137, making light work of India’s under-powered 240 all out, as a six-wicket win made his country six-time champions.

It also capped a great year for Australia across red and white-ball cricket, having also pipped India to the World Test Championship crown in June and retained the Ashes with a 2-2 draw on English soil.

Reflecting on a stunning sequence of results for his side, Cummins said: “It’s crazy. This year will be a year we remember for a long, long time.

“It’s been awesome. We’ve pretty much spent the whole Australian winter away playing overseas but we’ve had a lot of success and this pips it all. Top of the mountain. We saved our best for last.

“The passion in India is unrivalled around the world. Every single person here was wearing that blue shirt and whatever the result we were never going to forget a day like today.”

Cummins had a fine day at the office. He made the bold and inspired decision to send a power-packed Indian batting line-up in after winning the toss and then produced a superb, boundary-less 10-over spell that included the key wicket of player-of-the-tournament Virat Kohli.

But he was happy to give Head his moment in the limelight, as well as sharing with some of the backroom boys who helped him reach the final after he suffered a broken left hand.

He was not fit until their fifth match of the tournament and was not even in India when Australia lost their first two group games.

“Trav does what he does. He’s really brave, he takes the game on, puts pressure on bowlers and to do it on the biggest stage showed huge character,” Cummins said.

“It was amazing. We couldn’t be happier for Trav, he’s a legend and we love him… how fun is he to watch?

“It’s also on the unheralded few, the selectors that backed him in even when he had a broken hand and the medical team to get him back out there. It was a big risk that we took and it paid off.”

Head was struggling to take in the scale of his achievement, with each of his four sixes and 15 fours stamping down the hopes of the hordes of over a billion Indians.

He had earlier taken a cracking over-the-shoulder catch to remove India skipper Rohit Sharma in full flow.

“Not in a million years (could I have imagined this)… what an amazing day. I’m thrilled to be part of it,” he told Sky Sports.

“It’s a lot better than sitting on the couch at home (injured). I was very lucky to get back here.

“I couldn’t imagine getting a hundred, I couldn’t imagine holding on to that catch… but you want to help your team-mates and contribute so to do that on a big stage in front of a full house, under all that pressure, is something I’ll be able to look back on all my life.”

Home skipper Rohit, who had dreamed of delivering his country’s first global trophy in 12 years amid stifling expectation, cut a hollow figure at the close.

“It wasn’t our day, we tried everything but it wasn’t supposed to be,” he said.

“We know that we were not good enough today but I’m really proud of how we’ve played from game one.

“We kept losing wickets and couldn’t stitch up a big partnership, which is exactly what Australia did. Credit to Travis Head and Marnus Labuschagne, they stitched a big partnership and put us completely out of the game.”
