Brisbane and Ipswich are bracing for their worst ever floods, with tens of thousands of homes at risk and fears for citizens' safety, as the toll of dead and missing for the state-wide disaster continues to rise. The banks of the Brisbane River have broken and the flood peak will hit at 4am tomorrow. Already many suburbs are partially submerged, and 20,000 properties are likely to experience complete flooding in Brisbane. In Ipswich the river is rising, with 1,500 properties already evacuated and over 1,000 people waiting in evacuation centres. The death toll has risen to twelve people, the latest victims being two men found in Grantham in the Lockyer Valley. The number of missing people has been revised down to 51 people. We will be back updating this post tomorrow. Update: 5:45 pm Most of Brisbane's major roads have now been closed, with the Riverside Expressway now closed. Police are asking for people to avoid driving through Brisbane. More sad news from ABC 612:
Brisbane's Riverwalk will be demolished: engineers declare it poses a serious safety risk. It is already partially destroyed and submerged.

A quick update of some photos available, because 60 Minutes reporter Michael Usher took some truly incredible photos from Rockhampton and the Lockyer Valley today.

The infamous Wivenhoe Dam.
