GIPPSLAND town Poowong is set declare itself the first coal seam gas-free town in Victoria on Sunday.

The declaration will be made after the CSG Free Poowong group found 95 per cent of the 500 residents surveyed said they did not want the controversial mining in their region.

The dairy community will mark announcement with a 50m long human sign on the Poowong football oval.

Lock The Gate founder from Queensland Drew Hutton, who spearheaded a campaign which has closed over 15,000 farms to coal seam gas exploration and extraction, will speak at the event.

According to the Department of Primary Industries there are 18 CSG exploration licences in Gippsland, which include the shires of Bass Coast, Baw Baw and South Gippsland and Wellington shires.

In June last year the Victorian Government declared a moratorium on coal seam gas exploration and fracking until national guidelines are established for the onshore industry.

"We're the very first town in Victoria to declare ourselves coal and coal seam gas free," CSG Free Poowong spokesperson Ursula Alquier said

Mr Hutton said Gippsland should be protected from coal and coal seam gas mining.

"Areas like Poowong all around Australia are under threat from the expansion of coal and coal seam gas mining onto good farm land.

"We must protect communities like Poowong from high-impact, destructive activities like mining and the best way to do that is for landowners to lock their gates," he said.
