The flood-weary community has been ordered to evacuate for the second time in two days.
The Bureau of Meteorology (BoM) predicts the Wilsons River is likely to exceed 10.60 metres around 8.00am Wednesday.
“Further rises are possible in the afternoon,” BoM said.

The alert comes amid a severe weather warning for the Northern Rivers and parts of the Mid North Coast and Northern Tablelands.
