UPDATE 12.19PM: An evacuation order remains in place for Murwillumbah as NSW SES crews work to ensure the area is safe before residents are given the all clear to return.

Despite the order many residents were busy cleaning businesses and homes this morning as some got their first look at the devastation.

"The evacuation orders are still in place, so officially people aren't supposed to be there," NSW SES spokeswoman Heidi Groom said.

"The reasoning behind that is we can't issue the all clear until all the safety checks have been done…it is actually quite a hazardous environment."

Ms Groom said the SES still have 35 requests for rescue and confirmed some people remained stranded.

She said she understood people were keen to help with clean-up efforts but asked for patience.

"I know there's definitely a coordinated approach as far as clean-up and recovery processes," Ms Groom said.

"We just need people to be a little patient until the official word is given."

Ms Groom said motorists needed to use caution when driving through floodwater, after reports of further damage being caused from washes inundating homes and businesses.

Tweed Byron LAC police confirmed Tweed Valley Way remained closed.
