Australia captain Tim Paine acknowledged that his "inexperienced" and "inconsistent" side are missing the forbidden Steve Smith and David Warner.
Fast bowler Pat Cummins was the only Australian to cross 50 during the team's 137-team loss to India in Melbourne, with regular hitters again disappointed.
"I think he's inexperienced, it's pressure, India's bowling attack is probably as good as most of us have played," he said.
"I think it's pretty clear that if you take two or three of the best players out of the lineup of anyone around the world, sometimes you'll have problems and you'll have inconsistent performances.
"The positive side is that we have world-class players who will soon be available to come back to this side, and clearly when they do, they will make a big difference."
Smith and Warner are serving one year of suspension for handling the ball, and they will be back by the end of March.
Batting coach Graeme Hick said Australia should learn from India captain Virat Kohli and the first-inning centurion Cheteshwar Pujara with the unusually restricted Kohli 82 and Pujara, who is normally battling 106, providing the backbone of the total of 443/7 of the first entries from India.
Australia could only get 151 in response, with a slight improvement leading to 261 in its second chance, but still fell to a huge loss of 137 races.
"We talked about how Kohli did it (his 82)." We knew Pujara, and even Kohli, one of the most explosive hitters, got 20 of 25, 26 balls, and the rest of his innings took anything, "he said. .
"For the best player in the world to change his tickets and play like that, if he can not be in the same field as him and watch him and learn what he's doing, then he's in the wrong space."
"Certainly there are things that our players can get out of that, it takes a lot of discipline, a lot of patience and, besides that, you have to hit with the intention."
Aaron Finch's struggles as a trial opener continued, while Mitchell Marsh managed only 19 runs in both innings. There is a lot of speculation that one or both will be eliminated for this week's test in Sydney, although Paine did not commit to any changes in the XI.
"I think there will be a lot of things on the table in the next day or two and, of course, I have some ideas about what I think, but I will share them with JL (coach Justin Langer) before sharing them here." he said.
"But I think we have the best group of players available at the moment and we will choose the best combination of that group that we believe will win this final test."
The Marnus Labuschagne, of all races, has been added to the team as a possible replacement for Marsh.
