Meg Lanning believes her Australian side's ability to remain calm in the face of pressure has aided their success in this year's T20 World Cup, as the Australians prepare to face India in the semi-finals.

Australia confidently disposed of Sri Lanka in their final group stage match, winning by ten wickets, but are now facing their toughest test yet in the form of a 2020 T20 World Cup final rematch.

Speaking ahead of Thursday's do-or-die match, Lanning said the side was expecting toughness from India, but had belief in their own abilities.

"I do feel as a group we are very calm and we know that teams are going to come pretty hard at us and they have done that over the last few years," Lanning said.

"Just to be able to absorb some pressure is really important. You're not going to have it all your own way.

"Certainly with teams out there now, there's going to be times when they have got the momentum - but that's the nature of T20 cricket in particular.

"For us, it's just about staying calm in those moments, being really clear on what our plans are and trusting our ability as well.

"Depth does give us a lot of confidence as players going out there, knowing the strength that we're just trying to utilise that as best we can."

India have been the only team to defeat the Australians in the T20 format in close to two years, with Lanning's side now just one win away from making their seventh consecutive T20 World Cup final.

"We came here to be part of a game like this," Lanning said.

"We need to be able to adapt and play what's in front of us. I think that's really important in coming up with all the plans that you want.

"It's T20 cricket, it can change very, very quickly. We know we have to be on our game for the whole 40 overs.

"That's the challenge we've got because we know India are a great team and if we don't bring that then they'll certainly be allowed to play some good cricket.

"So we're excited about the challenge. I think that's what semi-finals are all about: playing your best cricket at the right time."

Australia's semi-final match against India gets underway on February 24, at Newlands Cricket Ground in Cape Town, scheduled for a 3pm local time start (12:00am AEDT).
