The northern Victorian town of Kerang will be isolated by floodwaters for a week as the state's flood disaster continues to unfold.
Victorian State Emergency Service chief operations officer Tim Wiebusch says a sandbag levee is expected to help keep the majority of Kerang dry, but with the Loddon River expected to peak Wednesday or Thursday the town will be cut off.
"We are asking the Kerang community to consider where they should now be moving to another location," Mr Wiebusch told reporters.
