Gilchrist, leading the side in the absence of Ricky Ponting, who has been ruled out of the first one-dayer due to a hamstring injury, also warned of the depth in the Australian squad.
The Indians have been riding high ever since their unexpected triumph at the Twenty20 world championships in South Africa, with a raucous welcome and non-stop celebrations marking their return home.
"We have enough preparation leading into this series. We were probably caught short at the T20 tournament but there's no excuse now," Gilchrist told reporters here.
"We know the conditions well here and with the amount of networking we've done we should be good to go," the dashing wicketkeeper-batsman said.
Gilchrist made light of the fact that the side would be without the injured duo of Michael Hussey and Shane Watson and also Nathan Bracken, awaiting the birth of his first child back home.
"We definitely have to rely on the depth in our squad. We have six changes in this, our first ODI since the World Cup, owing to retirement and injuries and babies being born.
"We've got a few new faces, which not a lot of people would have seen a lot of, and we're confident about them," he said.
