“Roads are now likely to be flooded. If you are near floodwater, you may need to get up as high as you can to survive,” authorities said.

“Follow your emergency plan if you are in danger. If you do not have a plan, it may be too late to leave safely.

“If it’s flooded forget it.”

The wider Gold Coast was on a lower watch and act warning to prepare for moderate to major flooding.

Across the border, the evacuation order for the Lismore CBD was lifted today with residents advised to return home “with caution”.
