Prime Minister Julia Gillard says more help is needed from the corporate sector to rebuild flooded parts of Queensland.

She is in Brisbane for a meeting of the business taskforce she set up, which includes industry and farm lobby groups, major companies, and state and federal political leaders.

Ms Gillard says corporate Australia can work alongside the Government's recovery effort.

"We do need more money, we do need in-kind assistance, and we do need the benefits of the kind of expertise that leading business people have, going directly into communities that are rebuilding after all the devastation," she said.

Ms Gillard has not given a timeframe for when the Government will decide whether a levy will be introduced to help fund the recovery.

"We're still waiting for the full details of the damage to be known," she said.

"I want to make sure I'm working off the best possible information I can get and as soon as I'm in a position to explain my decisions to Australia, I'll do that."

Talk of a possible levy is not supported by the Shadow Treasurer Joe Hockey.

"If you want to keep the Australian economy strong, you cannot keep taking a baseball bat to Australian households with more taxes," he said.

But Infrastructure Minister Anthony Albanese says the levy may be needed to repair roads and rail networks which will have far more than a local impact.

"It is also of national economic importance," he said.

Head of the Australian Industry Group (AIG) Heather Ridout, who is a taskforce member, says she is open to the idea of a levy.

"If we're going to put a levy on every time we have a problem, I think that is not the way to go, that is a knee-jerk reaction," she said.

"However we do have a here-and-now problem - we don't have the resources to meet it.

"All these issues are going to have to be considered."

Treasurer Wayne Swan will detail preliminary cost estimates on Friday.
