Michael Clarke's side travelled from Hyderabad to Chandigarh on Thursday and will resume training on Sunday ahead of the third Test starting in nearby Mohali on March 14.
Australia trail 2-0 and Wade says MS Dhoni's men would have their tails up after scoring massive wins over the tourists in the first two Tests.
"Two-nil up, I'm sure they definitely feel they're on top and no doubt they are," said Wade, who played the second Test with the aid of painkillers because of a fractured cheekbone.
"We've got to find a way to try to swing the momentum.
"Momentum can turn in one session.
"They probably turned it in a couple of sessions that Dhoni came out in the first Test (and scored 224) and they've probably ran with that momentum now.
"We need someone to step up with ball or bat to try to pull the momentum back our way."
While Australia's batting woes have been well-documented with Clarke the only player in Australia's top six averaging over 30, Wade says the bowlers also need to show more consistency in maintaining pressure after conceding 500-plus in the first innings of both Tests.
"When we bowled we probably let them off with a boundary here and there," he said.
"As a team we have got to apply a little bit more pressure to their batters, make them come at us a little bit more rather than us coming to them and letting the game roll along like that.
"We probably need to be a little bit more aggressive with ball and with bat.
"I haven't played much in Mohali at all so it's pretty foreign to me as it would be to a lot of the guys that haven't played over here.
"We've got to talk to the guys we can talk to in Michael Clarke and (former Test opener) Matthew Hayden who we had a good chat with after this (second Test in Hyderabad earlier this week).
"We've spoken to Shane Warne and we've had plenty of information about the conditions we're going to face and we've seen it up close for two Test matches.
"We've just got to get better."
