The Australian team is here in India to play a four-Test series and the experts have already put their money on the hosts which is largely due to the inexperience among the visitors.
''I agree that the aura has somewhat been diminished by India's performance in Australia earlier this year. And that's why both teams will be a little bit uncertain of each other,'' Buchanan told cricinfo.com in an interview.
Buchanan, who is also the coach of the IPL's Kolkata Knight Riders' team, said the current Australian team is very different from the Australian teams of the past which had a formidable bowling line up.
''This Australian side is different. There is no question about that. For this team, consistency will be defined by how it relates against other Aussie sides previously,'' he noted.
However, the former Aussie coach believes that Ricky Ponting has a brave attitude towards the game and he is the one who can spark the confidence in others.
''Ricky Ponting will remain the key. He is a determined man and has an unshakeable confidence, which will bring out the best from his team-mates,'' he added.
Meanwhile, opener Matthew Hayden was not convinced that his team had lost the aura because of some quick retirements and said, Australia being an invincible side, was always a perception which never came into the minds of his teammates.
''The whole thing about aura is that it's a perception and not necessarily reality. Obviously there has been a change in personnel.
''We are in a situation where we've got some younger players.
We haven't got a McGrath, a Gillespie, or a Warne, Langer or Martyn. It is a development of a new and challenging Australian outfit. It's a matter of whether we are good enough to win series, to put Test match wins together,'' Hayden stated.
