The muddy streak that is the Brisbane River from above

If not this vision filmed on Tuesday by Brisbane creative agency The Hype Project gives you an idea of just what the Queensland capital copped over the weekend.

Mud Armies are now on hand to clean up south-east Queensland after the floods killed nine people and ruined thousands of homes and businesses. And this video gives you an idea of just what they're having to remove - not just from from streets but from homes, offices and the river itself.

The damage bill from Queensland's flood disaster could top $1 billion as thousands of homeowners begin to assess the scale of damage across the southeast.

The Insurance Council of Australia says that more than 37,800 claims have been lodged to date, but it is still too early to pinpoint the overall cost.

However, the clean-up is underway as the state's mud army collects tonnes of flood-damaged items that continue to pile up outside homes and businesses.

"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 suggest that the damage bill for this disaster could be up to a billion dollars."
