Australia captain Aaron Finch has described his side's comeback series win in India as "unbelievable" and is confident they have the ODI game plan to win the World Cup.
Australia fought their way back from 0-2 down to beat India 3-2 in the five-match series, with a 35-run win in Delhi overnight clinching the historic result.
No Australian side had ever bounced back after losing the first two games to win the next three in a five-match campaign, and Finch couldn't be prouder of his squad.
"The resilience and fight that we showed being down 0-2 it would have been easy to roll over in those small moments in the game, just let them drift away and India win the series," Finch said after the win.
"But the fight that we showed, we've had our backs against the walls for quite a while now so I'm really proud of the group.
"From 2-0 down to win 3-2 is pretty special.
"I've been coming here for a while now trying to win and haven't, so have a lot of Australian players, so it's a special moment."
It took an all-round effort from the Australians to topple India in the subcontinent for the first time in a decade, led by Usman Khawaja and Pat Cummins, the leading run-scorer and wicket-taker in the series, respectively.
Khawaja was at the forefront of a batting group that finally clicked after showing signs of promise in at home this summer, racking up big totals in the three wins including the record 6-359 run chase in Mohali.
Finch said having a well-balanced batting unit that can play at different tempos is important if touring sides want to have success.
"If you go in with all attacking players in these conditions you're going to struggle, because we know the wickets slow up and the quality of (spinners Yuzvendra) Chahal, Kuldeep (Yadav), (Ravindra) Jadeja these guys they're too good to just walk out and blast them out of the park," Finch said.
"You need good batsmanship on these wickets and guys who know how to play situations."
Australia's style of play is similar to what worked for them when they won the World Cup in 2015 – take on the new ball in the powerplay, tick over the scoreboard and conserve wickets in the middle overs before launching at the back end.
But in India there appeared to be a real effort from the batters to impose themselves on the India spinners, often taking them for a boundary early on to put the bowlers on the back foot.
With the ball, the ability of leg-spinner Adam Zampa to take wickets through the middle overs has been a huge asset for Finch and the Australians.
While Finch believes Australia to be an underdog at the upcoming World Cup, he says his team's approach can defend the 2015 title in England.
"People have written us off for quite a while now," Finch said.
"We always knew that the plans and the style that we wanted to play are all there, can win us the World Cup, win us big series against great teams and India are definitely a great team.
"It's about ourselves believing we're good enough and sticking to our game plan.
"We did that for four of the five games and India were too good in a close one in Nagpur.
"To get over the line in three of them was a great series all round."
