"But we felt the team played well in Brisbane and it is important to keep a winning team.''
Christian would have added another bowling option but Clarke believed in his three-pronged pace attack complemented by spinner Nathan Lyon.
He said he would inject himself, Warner and Mike Hussey into the attack - as he did in Brisbane - to share the bowling load.
"There is a lot more grass (on the wicket) than I have ever seen at Hobart,'' Clarke said.
"Day one is going to be tough for the batters, especially if it is overcast, then hopefully it will turn into a pretty good wicket.
"I see Lyon playing a big role for us.
"There is probably a concern if your front line bowlers don't do the job with the new ball. It could be quite a long day but I am confident.''
The second Test starts on Friday.
Australia: David Warner, Phil Hughes, Usman Khawaja, Ricky Ponting, Michael Clarke (capt), Mike Hussey, Brad Haddin, Peter Siddle, James Pattinson, Mitchell Starc, Nathan Lyon. Dan Christian (12th man).
