The threat of a series of wells across the Manning is becoming more likely, as a result of mining companies' extended aerial exploration of the Mid North Coast.

The Times understands there have already been two successful test drillings on a property off Warrawillah Road, betwen Mooral Creek and Marlee, and at least one landowner in the Cedar Party area has consented to a test production well being drilled on his property.

A public meeting will be held at Mooral Creek Hall tomorrow night, as well as a forum, also tomorrow night, at Laurieton United Services Club, to more fully explain coal seam gas mining and the threat it could pose to the amenity of the local area.

The public meeting at Mooral Creek follows a gathering at Marlee about a fortnight ago.

Flyers have since been distributed to properties in the Upper Manning warning of the threat, and inviting public discussion on the issue.

One of the organisers of tomorrow night's meeting at Mooral Creek, Paul Segal, said "There's nothing definite (from the mining companies) at this stage, but the public needs to be aware of what they can do if they want to prevent this kind of operation happening in their area."

Mr Segal, who is president of the Mooral Creek Hall and Progress Association, will screen two videos which highlight what happens in coal seam gas production, including the controversial 'fracking' process.

He said the community needs to be alerted to the possible loss of amenity in their area caused by the noise, lights and environmental damage gas seam mining can cause.

Destruction of flora, fauna and aquatic species, as well as additional erosion and effect on water quality are high on the list of concerns, Mr Segal said.

He said community members share the concerns of MidCoast Water which has already sent a submission to the State government.
