Footage has emerged online showing a north Bundaberg street completely submerged in water, as severe flooding in Queensland shows little sign of relief.

The death toll as a result of the floods has now reached four, with thousands evacuated and living in shelters.

Bundaberg, north of Brisbane, has been the hardest hit city according to local media. Rescue crews plucked 1,000 people to safety after the river that runs through town broke its banks, sending fast-moving, muddy water pouring into streets and homes.

Around 1,500 residents fled to evacuation centers, while patients at the local hospital were being airlifted to Brisbane as a precaution.

Floodwaters are expected to peak in most of the worst-hit areas later Tuesday, officials were rushing to move those in the highest-risk areas to safety.
