One of the most popular bushwalks in northern New South Wales is becoming increasingly dangerous, rescuers say, with 15 rescues on Mount Warning this year.

Tweed Volunteer Rescue Association spokesperson, Drew Carr, told ABC Radio a combination of the track's condition and people being unprepared for its difficulty has led his group to discuss the need for a dedicated rescue service just for the mountain.

"We are being called upon more to the mountain so we are trying to work out what we are doing here," he said.

Mr Carr said the group is considering proposing a team of up to 40 volunteers who can form a dedicated mountain rescue team.

"They might be trained in not only land search but vertical rescue as well," he said.

Mr Carr said the Mt Warning track was damaged by ex-tropical cyclone Debbie last year.

"The water rushed down that mountain like you wouldn't believe, sweeping away part of it," he said.

Mr Carr said the track was closed to the public for repairs to the lower section, but that was not the only damaged part of the path.

"A lot of degradation all the way up which has exposed tree roots and slippery rocks and bigger steps now," he said.

"It's becoming quite a challenge to walk."

Mr Carr said the climb had become a "professional walk" and said a section that relies on people pulling themselves up with a chain is particularly difficult.

But he was also concerned by people who climbed the mountain without the proper clothing or preparation.

"People not wearing proper enclosed shoes or even hiking boots, people just wearing singlets — the weather can change up there so quickly they get cold," he said.

He is urging people to research the climb before doing the Mt Warning walk to make sure they understand track conditions and what they need to take on the hike.

The State Parliament Member for Lismore, Thomas George, said he was not aware of the call for a dedicated rescue service for the mountain.

"I have a strong working relationship with all the various volunteer emergency service organisations in the Tweed," Mr George said.

"To date I have not received any correspondence from the Tweed Volunteer Rescue Association regarding its concerns about rescues on Mt Warning and such I am unable to comment at this time."

Hikers asked not to climb the mountain

Destination Tweed chief executive Rose Wright said her organisation does not encourage tourists to climb the mountain, which is also known by its Indigenous name, Wollumbin.

"There is a lot of work that needs to be done on the Wollumbin track. There is limited parking there and there is certainly limited facilities," she said.

"There are signs there requesting people do not climb the mountain because it is a sacred site.

"It is a very special site for the traditional owners of our region, so we do discourage people from climbing the mountain out of respect."

Ms Wright said there are other low-grade walks around the mountain that can be walked, without going to the summit.
