India batsman Rohit Sharma said Australia tour will be a different ball game for India but said his side were full on confidence after the victories against West Indies.
India extended their form in the T20s (3-0) after winning the ODI series (3-1) and Tests (2-0) against West Indies.
But Sharma said a series against Australia even without the trio of Smith, Warner and Bancroft would be a challenging ask.
"Australia is always challenging when it comes to going out there and performing. Every time you go there, you are tested as a player, as an individual and as a team as well," the veteran opener said after Sunday's win.
"I think we have got to be at our best and when you win a series like this (West Indies) and when you play like that in the tournament you are high on confidence. It's all about taking that confidence to Australia and doing what we did as a team."
The 31-year-old batsman stressed that it was important for his side to start fresh and not think a lot about what happened in the past.
"The best teams in the world keep repeating those performances. It will be important for us that we start fresh. Not think about what we have done in the past."
Sharma, who missed out on the Test series in England, said his focus was on the T20s first which start from November 21.
"I am someone who doesn't think too far ahead. So I am focusing on the T20 series first," said Sharma.
"Of course the Test match is something that I was looking forward for a long time and it will be nice to go out there and represent India in Tests, but we want to win the T20s first."
