How bad is the flooding? Here's just one video.
There's dozens more videos and pictures all over the internet and things are still expected to get worse. They're currently predicting the floodwaters will peak on Thursday but obviously that depends whether more rain falls.
Many people are still missing though it's hoped everyone else will have enough warning to get to safety as the flooding continues.
Seriously scary stuff. Stay safe, Queenslanders! :(
