The state's mud army is out in force as tonnes of flood-damaged possessions pile up outside homes and property damaged by the deadly floods.
"It's clear that the flooding disaster emergency here in the southeast is not over yet, but the recovery process has begun," Deputy Premier Steven Miles said on Wednesday.
"Early estimates suggests that the damage bill for this disaster could be up to a billion dollars."
As floodwaters slowly being to recede, volunteers are racing against mother nature with potentially severe storms forecast to batter the southeast in coming days.
More than 8000 volunteers have signed on to help with the massive relief and recover effort underway across the southeast.
While the true extent of the damage is still being assessed, Queensland claim numbers have already topped 13,000 with insurer Suncorp.
"That's an extraordinary number of claims in a very short period of time," Suncorp CEO Steve Johnston said.
"The key thing for us will be to get assessors on the ground and we're doing that in the next 24 hours starting in Gympie.
"And then we'll work our way down the coast."
But Mr Johnston said it was already clear the state would be dealing with "large losses" and urged the recovery to "build it back better".
"There's also a lot of flash flooding, a lot of damage from that extraordinary weather that we've seen.
"The inevitability here is that we are going to be repairing homes that have been repaired three or four times.
"And so what this really brings to bear is the need to build it back better.
"We need to take account of the water, where that water is flowed, and work with our customers and work with the industry more broadly to build homes that are more resilient."
The focus is now on getting people back to their homes and business while repairing vital infrastructure, Queensland Disaster Reconstruction Authority CEO Brendan Moon says.
"This will be a big task for Queenslanders, but we have done this before. The community, local government and state government and the Commonwealth Government will come together to support the recovery of our communities just as we've been done before."
A support package is needed for small businesses negotiating the pandemic before being hit by flood damage, the Liberal National opposition says.
"We've suggested targeted grants, payroll tax relief, sick leave cover and electricity and water rebates," small and family business spokesman Brent Mickelberg says.
