I will worry about cricket later: Clarke

His comeback may loom but Australian captain Michael Clarke claims cricket is the last thing on his mind ahead of Saturday's World Cup clash with Bangladesh as a cyclone batters the Queensland coast.

The Gabba match had been set to mark Clarke's return from December hamstring surgery.

Clarke is the only confirmed starter after the skipper refused to reveal their XI on Friday, saying it could change again if rain reduces the match's overs.

Clarke said they would not take Bangladesh lightly if they got on the field on Saturday but the match almost seemed to be an afterthought for the returning skipper due to Tropical Cyclone Marcia.

The cyclone hit the central Queensland coast on Friday morning as a category five system but has since been downgraded to three as it moves south down the coast.

"The forecast is obviously not great but to be honest our main focus is on the people of Queensland," Clarke said.

"As much as we would like to get out on the field and continue our form I think we need to realise how bad this cyclone is and hope that everyone is healthy and safe.

"We will worry about the cricket tomorrow.

"(But) if we get on the field we will be 100 per cent ready."

Australia had been tipped to unleash four quicks on a bouncy Gabba deck but Clarke would not give anything away on Friday.

"We have selected a team but I am not going to announce it today because it could change if the game's format changes," he said.

"That gives the selectors options.

"It wouldn't be smart to announce it right now."

Clarke said he was primed for a comeback after being rested from Australia's World Cup opening win over England.

"This is the first time in my career that I have had to have surgery," said Clarke who suffered the hamstring injury in the first Test against India in December.

"I had niggles in the past but I haven't missed as much cricket as I have in the last couple of months.

"But I put faith in my preparation and work I have done.

"I am 100 per cent confident I can walk out on the field and help the team achieve success."

Stand-in skipper George Bailey is tipped to make way for Clarke.

Clarke said Bangladesh loomed as a genuine threat after watching them thrash Afghanistan in their opening World Cup match.

Especially if they face them on a spicy Gabba deck, as expected.

"We are certainly not taking them lightly," he said.

"It is going to be a tough wicket to play on so we have to be as well prepared as we can be, and play our best cricket to beat them."

Australia abandoned training at the Gabba indoor nets on Friday afternoon, opting for Brisbane's National Cricket Centre.
