Over the course of the floods, the NSW coast has been drenched by at least 200 millimeters of rain, and in some places, more than 400 millimeters.
This is more than three times the Sydney average for the whole of March.
The flooding stretches 600 kilometres from Sydney to the Northern Rivers.
The Bureau of Meteorology's Victoria Dodd said the state had experienced "the most significant floods in decades".
