Knitting Nannas Against Gas activists have been sitting peacefully outside Member for Dubbo Troy Grant's Talbragar Street electoral office on a weekly basis since December last year.

When The Nationals opened an election campaign office in Macquarie Street at the start of February the knitters decided to protest at both locations.

This week they discovered Dubbo City Council rules on the use of footpaths had been breached.

Gasfield Free Dubbo convenor Sally Forsstrom said the Knitting Nannas were unintentionally at fault.

"We have council permission to protest outside Mr Grant's Talbragar Street electoral office and did not realise additional approval was needed for the Macquarie Street campaign office," she said.

"The Knitting Nannas have a philosophy of being very well mannered and certainly don't want to get a different reputation in Dubbo.

"We are aware of the Summary Offences Act and ensure we follow the rules outlined by police."

Ms Forsstrom said the protest group had enjoyed a cordial relationship with Mr Grant.

"He and his staff have always been very pleasant and so have we," she said.

"Mr Grant respects our right to protest against CSG and we ensure that we are not hindering people going into or out of his office. Our aim is to heighten awareness of the very real human and environmental dangers associated with CSG."

Mr Grant told the Daily Liberal he had not "pushed out" the protesters.

"Regulations over the use of the footpath are a matter for Dubbo City Council and have nothing to do with me," he said.

"The knitters have been sitting outside my Talbragar Street office for months and I have offered them tea, coffee and cake every week.

"I have had them in my office to talk about their concerns.

"I get on fine with them and agree that they have the right to protest.

"I have suggested they may also wish to sit outside the Labor and Greens offices because Labor granted all the CSG licences and The Greens supported the issuing of the licences."

Mr Grant's campaign director Peter Bartley said an application to use the footpath outside 37 Macquarie Street was lodged with council on January 28.

On February 2 approval was granted to use the area from February 9 to March 30.

"We want to display signs, put up tables with information and run a couple of street stalls," Mr Bartley said.

"I have been running election campaigns for a long time and the first thing I do at every shopfront location is make an application to use the footpath. It is a standard step to take.

"I knew the Knitting Nannas were sitting outside the state member's Talbragar Street office and didn't think about them wanting to use two sites.

"Council will not permit dual occupancy of the same area."

Mr Bartley said the knitters "showed up" on February 4 when The Nationals were moving furniture into the campaign office.

"They didn't talk to us or seek permission or approval.

"I said hello and asked them to let me know if they had any problems or needed anything.

"They didn't appear on February 11 but were back again on Wednesday. No malice was directed against them and we we're not trying to push them out.

"It is simply a matter of council not allowing two groups to use the same footpath.

"As the election draws closer we will be doing more outside the campaign office. We have already had a large stream of people coming in asking for postal vote applications."

Knitting Nannas Against Gas Narromine member Helen Jeffery was surprised to learn she was no longer able to protest outside the campaign office.

"I am not a malicious person or a professional protester," she said.

"I just want to make the community aware about CSG. I will be back protesting in Dubbo in the coming week in a different location."

Dubbo City Council manager business support environmental services Ken Williams said any group, charity or non-profit organisation that wished to occupy public space must seek formal approval from council.

"Application forms are available at the front counter or on council's website," he said.
