Tweed fires have all been extinguished
Updated, 10.54am: ALL fires burning in Tweed have been extinguished.
"They're all out," Far North Coast coordinator of operational services Inspector Matt Inwood said.
Investigators found the Clothiers Creek Rd fire, which burnt 20ha of land on Monday evening, was caused by an out of control burn off.
Insp Inwood reminds the public there are precautions that need to be taken when burning off.
"People need, by law, to take precautionary measures," he said.
"They have to have water nearby and they're obliged to stay with the fire."
There are many more rules when it comes to burning off, visit http://www.rfs.nsw.gov.au for more information.
A second fire at The Rock, Evrion Rd has also been extinguished.
Initial, 12.19pm: An initial investigation into the Clothiers Creek Rd fire has found it was started after "an escaped hazard reduction burn".
Far North Coast coordinator of operational services Inspector Matt Inwood said the investigation was still being finalised but a burn off was likely the cause.
Insp Inwood said he could not speak more on the issue until the investigation was finalised and a course of action decided.
He could not say if the person responsible would be charged.
The grass fire at Clothiers Creek Rd, Tanglewood Flats and a bush fire at The Rock, Eviron Rd are now listed as a controlled status.
"There's little to no fire activity," he said.
"We made it through the windy conditions over night."
Volunteer firefighters have worked tirelessly around the clock to keep both fires at bay.
Both fires caused extreme smoke haze in the Tweed on Monday afternoon and forced road closures.
