The Rural Fire Service is asking for community help in today's severe bushfire danger.
Very hot temperatures, combined with low humidity and gusty winds has the entire north coast subject to a total fire ban until at least midnight.
RFS spokesman Ben Shepherd said there are over 20 fires burning between the Great Lakes and the Queensland border.
He said the public has a huge role to play in reporting new fires.
"If you do see a fire today and there is no one in attendance you need to call Triple 0 immediately," he said.
"Don't just presume someone has actually reported it.
"It's in these conditions that if we're not there quickly the fire's can escalate and then actually cause a great deal of problems.
"We have got thousands of firefighters right across the state ready to respond and they'll be backed up by aircraft."
The conditions are expected to be challenging for crews working to control new bushfires in the Clarence Valley.
RFS Clarence controller Stewart Watts said of the 20 or so fires burning along the north coast most are currently under control and in remote areas.
"Unfortunately two other fires came in late yesterday afternoon south of Grafton around the Nymboida area," he said.
"These fires are going at this point in time which means there are very limited crews on the ground and no real containment strategy developed at this time.
"That is concerning given we're entering a day of severe bushfire danger."
