Virat Kohli believes the "remarkable" Glenn Maxwell has set a brilliant example for all cricketers by deciding to temporarily step away from the sport and focus on his mental health.

Cricket Australia announced ahead of the third Twenty20 against Sri Lanka two weeks ago that, following a talk with head coach Justin Langer, Maxwell would take a short break for personal reasons.

India captain Kohli commended the all-rounder and recalled difficulties he wrestled with alone while he struggled for runs during India's tour of England five years ago.

"I'm absolutely for it," Kohli said of Maxwell's decision ahead of the first Test against Bangladesh in Indore, which begins on Thursday.

"To be very honest, everyone is focused on what they need to do. It is difficult for anyone to figure out what is going around in another person's mind.

"I have gone through a phase in my career where I felt like it was the end of the world. In England in 2014, I did not know what to do and what to say to anyone and how to speak and how to communicate.

"I could not have said I am not feeling great mentally and I need to get away from the game because you never know how it is taken.

"I think these things should be of great importance because if you think that a player is important enough for the team or Indian cricket to go forward. I think they should be looked after. When you get to the international stage, every player needs that communication, that ability to just speak out.

"I think what Glenn has done is remarkable and he has set a right example for the cricketers all around the world that if you are not in the best frame of mind, you try, try and try but as human beings, you reach a tipping point at some stage when you need time away from the game. Not to say you give up, but just to gain more clarity."

Australia all-rounder Glenn Maxwell is taking a short break from cricket to address "difficulties" relating to his mental health.

Maxwell played and performed well in the opening two games of Australia's Twenty20 series against Sri Lanka but will not be involved in Friday's third and final match at the MCG following a discussion with coach Justin Langer.

Western Australia and Hobart Hurricanes batsman D'Arcy Short replaces him in the squad.

"Glenn Maxwell has been experiencing some difficulties with regards to his mental health," said team psychologist Michael Lloyd.

"As a result, he will spend a short time away from the game. Glenn was proactive in identifying these issues and engaging with support staff."

Australia coach Langer commended the short-form star for being open and honest about his struggles, which he said became more noticeable before last week's win in Adelaide.

Maxwell hit a quickfire 62 in that match and appeared to be in a jovial mood during Wednesday's second game at the Gabba as he spoke freely with broadcasters while wearing a microphone on the field.

"That's the mask he puts on, it's his armour, his energy and the way he plays," Langer told reporters in Melbourne.

"He's the great entertainer but underneath the mask - you probably just sense it.

"When you build relationships with people you sense when they're not quite right and I asked him the day before the Adelaide game and that's when he said we probably need that little chat.

"It took a lot of courage for him to say he wasn't feeling right."

Australia won the toss and chose to bat first against England in Thursday's Cricket World Cup semi-final at Edgbaston.

The tournament hosts struggled badly when chasing against Aaron Finch's men during the group-stage defeat at Lord's, while they also showed frailties in failing to overhaul a moderate score in a shock loss to Sri Lanka at Headingley.

England captain Eoin Morgan confirmed his side was unchanged from the one that hammered New Zealand to seal a place in the semis, while Australia's sole alteration sees Peter Handscomb come in for the injured Usman Khawaja, as had been announced by head coach Justin Langer prior to the game.

There had been talk that Matthew Wade - called into the squad as Khawaja's replacement - may be selected ahead of Glenn Maxwell, but the all-rounder retained his place in the XI.

Not since 1992 have England gone this deep at the World Cup, while Australia are aiming to continue their perfect record in semi-finals, having progressed from all seven of their previous matches at this stage of the competition.

The victors will go through to Sunday's final at Lord's to face New Zealand, who sensationally defeated India at Old Trafford on Wednesday.
