More than a week after the Queensland government announced a proposed package to help flood victims "build back better", the federal government has not responded to a request to split the cost.
Deputy Premier Steven Miles announced the $771 million package last Saturday, the same day the state government formally asked the Commonwealth to jointly fund the proposal.
Mr Miles said the funding has the potential to change the lives of people affected by the floods.
"I'm sure people whose houses have been inundated are disappointed the package hasn't been approved," he said.
Treasurer Cameron Dick said they want a "prompt and quick decision".
"More wild weather is predicted for Queensland in the coming week," he said.
"We don't want to muck about. It's an absolute no-brainer.
More than 4,300 homes and commercial buildings in Queensland have been assessed as having severe or moderate flood damage.
Almost 3,500 properties have minor damage.
The proposal includes a program to raise up to 1,000 homes and grants of $50,000 to help up to 5,500 households "build back better" by retrofitting to make them more flood resistant.
A voluntary buy-back scheme worth $350 million would see up to 500 high-risk homes resumed.
The structural assistance grant to help make homes safe and liveable would be increased from $15,000 to $50,000.
Under the package, councils would also receive $30 million for clean-up costs not covered under existing funding.
The Prime Minister's Office, when approached for comment, referred the ABC to comments made on Tuesday by Scott Morrison, when he said the proposal was being considered and going through the "normal process of assessments".
"The support that we've already provided here in Queensland is over half a billion dollars directly by the federal government," Mr Morrison said on Tuesday.
The office of the federal Emergency Management and National Recovery Minister, Senator Bridget McKenzie, did not return phone calls from ABC News for a response.
Homeless flood victims under pressure to build back quickly
Bianca and Dylan Macauley's house at Oxley in Brisbane's south-west was flooded most of the way up the second storey.
The couple has three young children and no insurance.
They consider themselves fortunate because they could borrow money from relatives to quickly rebuild their gutted house so they could have somewhere to live.
They're using cement sheeting and installing higher power points in the downstairs area, but won't flood proof the second storey.
"We'll do gyprock because of the cost, we can't afford the cement sheeting upstairs," Mr Macauley said.
Calls for flood resistant materials to avoid another repeat of the disaster
Nicole Johnston is the local councillor for Tennyson Ward, which takes in flood-hit suburbs including Oxley, Fairfield and Yeronga.
She said the "big danger" for flooded homeowners in building back is that they "do exactly the same as before".
"The gyprock goes back up and they move back in," Ms Johnston said.
"They remain at risk, they remain in houses that have flooded two or three times and this is going to happen to them again.
"Council and the state government have a critical role to play here in mandating flood-resistant materials so we can build back better," Ms Johnston said.
She said the state government's proposed flood resilience package "looks like it's heading in the right direction."
"All of the key issues that we need out here in the flooded south-western suburbs are addressed," she said.
"The key will be who will be eligible and hopefully state, federal and council can all contribute so that we can build back better in the future.
Ms Johnston said one month after the disaster struck, many vulnerable families were "in limbo".
"They don't have the money to undertake demolition and they don't have the money to rebuild, either their own money or grants," she said.
"They really need assistance now in helping them plan what their build back is going to look like."
