Liverpool Plains grain and cattle farmer Megan Kuhn said a bus leaving Dubbo on Sunday, March 15 would travel to Gunnedah for an event harnessing unity and spirit to protect water, farming land and the environment.

"Individuals, families and groups from a large part of NSW will be participating and I would like to see caring people from Dubbo and district involved," Mrs Kuhn said.

"We will be standing together to show that we are strong in our determination to keep our communities mining and gasfield free."

Mrs Kuhn said people from all walks of life were worried about CSG contamination incidents documented at Camden, Gloucester and Narrabri.

The Narrabri CSG project planned to put 850 gas wells into the Pilliga forest and recent approval for the Shenhau coal mine on the Liverpool plains would have further impact on ground water, she said.

Once the Narrabri gas field gained final approval activists feared there would be pressure for the industry to extend through Coonabarabran to Tooraweenah and the Goonoo forest where mining giant Santos had applied to renew a 5762km2 petroleum exploration licence north of Dubbo.

Mrs Kuhn said there were grave concerns about the risk of damage to the Great Artesian Basin, contamination of water resources, harm to the environment and heritage and significant impacts on human and animal health.

"As the NSW election draws near I urge people to take the opportunity to join the March 15 regional event to demonstrate a collective voice against mining and CSG," she said.

"I have been involved in a community survey process across more than three million hectares of the north-west.

"We have gone door to do door, neighbour to neighbour asking people if they want their properties, communities and roads to be gasfield free.

"The work has been carried out over two years with the intention of approaching 100% of communities.

"So far 2.7 million hectares have declared they want to be gasfield free.

"We are waiting on the final results from the rest of the survey areas."

Mrs Kuhn said companies stated communities wanted the security offered by mining.

But she said people on the ground were saying something very different.

"Communities are united in their objection to mining and CSG," she said.

"They are prepared to stand up for what they believe in."

Mrs Kuhn said mining companies did not understand "the sense of place" in north-western NSW.

"They don't have respect for the forest, valuable farm land and communities," she said.

"The companies seem to view the land as something to drill and dig up.

"People united by the survey process are prepared to keep a watchful eye and protect communities from the harmful effects of mining and CSG."

Mrs Kuhn and her family graze Angus beef and multi-purpose Merino sheep on the south-west corner of the Liverpool Plains in front of the Coolah Tops National Park.

"On a good day we used to be able to see Mount Kaputar from our place," she said.

"We haven't been able to do that for a couple of years due to the mine dust in the air.

"When our son Marcus was a baby, we were approached by a gas pipeline company wanting access to our property.

"We were just finding out that Marcus had medical conditions that would require special attention. We weren't really concentrating and the company didn't say the infrastructure would be the backbone of trying to unleash CSG in our whole area.

"When we discovered that we felt so betrayed. We felt the company had taken advantage of our situation."

Mrs Kuhn said other landholders had experienced difficult situations with mining companies.

"It is as if the industry has been trying to pluck us off one by one with a divide and conquer strategy," she said.

"That's why the community survey process has been so important - it has allowed people to have an ongoing conversation about CSG and mining."

Mrs Kuhn said she never expected to be vice-president of the SOS Liverpool Plains group, a Lock the Gate member or co-ordinator for the North West Alliance.

"I am a busy mum with a special needs child who requires virtual 24-hour care.

"The community helped us when we were in deep need. Assisting with the community survey process has allowed me to give something back.

"Surveys have not be carried out to isolate those who think differently about mining or CSG.

"The process has been a way of allowing people to have a genuine conversation about how they feel while heightening awareness of the risks mining poses to water, land and the environment."

Gasfield Free Dubbo convenor Sally Forsstrom echoed the statements made by Mrs Kuhn.

She said community concern about CSG and mining was growing on a daily basis.

"The Knitting Nannas Against Gas are a weekly presence outside the office of Member for Dubbo Troy Grant every Wednesday," Ms Forsstrom said.

"Dressed in yellow and black and surrounded by Lock The Gate and No Gasfields signs, the knitters talk to people passing by and hand out information on the dangers of CSG.

"Gasfield Free Dubbo is a non-political group so we don't care who people vote for but we do ask the people to consider the impact of CSG. It would be even better to talk to the candidates about a subject that is too important to ignore.

"People interested in participating in the day of community action at Gunnedah are welcome to travel there independently or to board the bus leaving Dubbo at 8am on March 15."

Greens candidate for Dubbo Matt Parmeter and Independent Colin Hamilton stand firmly opposed to CSG mining.

Labor candidate Stephen Lawrence said he was personally yet to be convinced it would ever be safe to proceed with CSG.

His party's policy was to impose a moratorium on the issuing of any more exploration or extraction licences until science demonstrated it was safe to allow the industry to expand.

Member for Dubbo Troy Grant believed CSG should only develop where it was safe and appropriate to do so.

Santos general manager energy Peter Mitchley told the Daily Liberal his company had no interest in going onto land where owners were not willing to host the company.

He said exploration work in the Goonoo forest was "a world away from getting out on the ground".

"At the moment we are focused fully on the Narrabri gas project," he said.

"The Goonoo exploration licence is in its infancy in terms of gas potential. More studies are needed to understand what the regional geology is doing."
