More than 150 rescues were undertaken on Wednesday alone, including in Coffs Harbour and Taree, where the Manning River broke the record of six metres set in 1929, before plateauing towards noon.
More than 80 warnings were in place late on Wednesday morning after falls of up to 280mm in some areas.

Most rescues were in Taree, Wingham and Glenthorne, including several cars caught driving into floodwater.
