Coach Andrew McDonald has defended Australia's preparation for their series in India after the tourists suffered a humiliating collapse to lose the second Test in Delhi.
Australia were in a winning position at the start of day three but by tea the match, and their hopes of securing the Border-Gavaskar series, were gone.
The world's No.1 ranked Test team lost 9-48 in 90 minutes as they recklessly tried hitting and sweeping India's star spinners Ravi Jadeja and Ravichandran Ashwin.
While dealing with the fallout from the humiliating defeat, the tourists were also grappling with personnel issues on Monday.
Fast bowler Josh Hazlewood will head home after struggling with an achilles injury which kept him out of the first two Tests, and veteran opener David Warner could join him back in Sydney after suffering a concussion and a fractured elbow in Delhi.
Captain Pat Cummins has flown back to Sydney due to serious family illness but is expected to return ahead of the third Test from March 1.
Australia opted against playing a tour game in India, preferring to ready themselves for the blockbuster series by training on spin-friendly pitches in Sydney, and then in an intensive training camp in Bangalore.
Several Australian stars, including Steve Smith, Marnus Labuschagne, Usman Khawaja, and Warner, opted to play in the Big Bash League immediately before joining the side's training camp.
The second Test was an improvement on the series opener in Nagpur, when Australia were smashed by an innings and 132 runs, but their second innings in both matches were marred by nightmare collapses.
"I still wouldn't have changed what we did leading in, there's no doubt about that," McDonald said in Delhi on Monday.
"I think they had really good preparation in Bangalore, so there's not any excuses.
"At the end of day two, if you said our preparation was good, you'd probably have a different slant on it, but within an hour then people start to critique what happened in the past.
"I don't think that had a great bearing on what happened in that hour, we were prepared for that, and day three, as well as we could have been and we failed under the examination of India."
Former Test captains including Allan Border, Ian Chappell and Michael Clarke have slammed Australia's tactics in India with bat, ball and in the field.
Australia tried to counter Jadeja and Ashwin through aggressive sweeping but the tactics came unstuck in embarrassing fashion.
Jadeja could only laugh when asked post-game if it was a good idea to try to sweep his bowling on a pitch in Delhi.
"Our methods are going to be critiqued, and rightfully so," McDonald said.
"There were some people who went clearly away from the game plan that made them successful over a period of time and that's for us to own as a collective.
"We've got to be better than that, that's the bottom line, we've got to own it and we are not here to shy away from the fact that wasn't good enough."
Australia will weigh up multiple changes to the squad for the third Test in Indore, starting on March 1.
Bowling allrounder Ashton Agar and out-of-form batter Matt Renshaw are contenders to be sent home as both players are unlikely to feature in the remaining two Tests.
Australia wanted to train in Delhi on Monday and Tuesday, what would have been days four and five of the second Test, but have been unable to find available facilities.
