A huge sinkhole has opened up on a residential street, after rain drenched the NSW north coast.

In the last five days, more than 600mm of rain has been dumped in Coffs Harbour, causing the massive sink hole, which was shared to social media by ABC’s Jake Lapham.

Lapham said the sink hole appeared on Pearce Drive in Coffs Harbour, and a photo shows the area has already been taped off.

The Bureau of Meteorology has issued a severe weather warning for parts of the northern rivers and mid-north coast, with more heavy downpours and unusually high tides forecast.

The deluge has also prompted widespread flooding around the northern rivers, with evacuation orders remaining in place in Condong and Tumbulgum, north of Murwillumbah.

The order came after the Tweed River burst its banks near Tumbulgum on Tuesday, with minor to moderate flooding in the area.

Heavy rain severely damages road

The NSW SES Murwillumbah Unit shared a shocking photo of a damaged road to Facebook on Wednesday.

The photo was taken at 6.30am after the flood water at Dungay Road has receded, while parts of the road remain flooded, it appears the heavy rain has severely damaged the road.

“You never know what's under flood waters,” the post said.

On person in the comments said the photo showed why people should not drive through flooded waters.

“A disaster of a car overturning would result in deaths,” they said.

SES called to hundreds of jobs

The SES attended 85 jobs overnight and has performed 24 flood rescues since the extreme weather began on the weekend.

In total the SES has attended more than 1016 jobs.

"The majority of those jobs are fixing leaking roofs and damage due to heavy rainfall or trees down due to strong winds and we're also getting requests for sandbags," and SES spokeswoman said on Wednesday.
