BAFFLE Creek residents are worried about an international company planning to mine oil shale in the Lowmead/Baffle catchment area.
But, according to the company's website, the reserves in the area are considered unclarified or not viable at this stage.
Coal Free Wide Bay Burnett spokeswoman Vicki Perrin said residents of Baffle Creek were alarmed to hear of exploration permits being sought in the Baffle Creek catchment by Blackall Oil.
She said it was also learned that Greenvale Energy was proposing an oil-shale mine in the Lowmead/Baffle catchment area.
"Oil shale and shale gas are terribly polluting industries," she said.
"We have seen disaster after disaster in oil-shale mines and gas fields both here in Australia and in the US.
"Baffle Creek is renowned for being the last untouched waterway in Queensland.
"This Queensland icon should be protected."
Ms Perrin said every effort should be made to retain the health of the "national environmental treasure" for future generations to enjoy.
She said the Lowmead oil-shale deposit contained about 1.72 billion tons of oil shale.
She said its proximity to Gladstone and Bundaberg ports made it an attractive site to mine.
"Interest in the Lowmead oil-shale deposit is held by a joint venture consisting of Greenvale Mining NL and Queensland Energy Resources Limited," she said.
Ms Perrin called on the Queensland Government to prohibit oil-shale, coal and gas mining in the only remaining pristine waterway in the state.
"The Wide Bay, Burnett and Fraser Coast should not be turned into an industrial wasteland as we have witnessed on the coast in Gladstone and inland at Chinchilla/Hopelands," Ms Perrin said.
"Another disaster such as what has occurred in Gladstone Harbour in World Heritage-listed waters would annihilate our sustainable tourist and fishing industries."
Greenvale Energy did not return attempts to contact its Perth Australian headquarters.
But its website reports "commercial mine and processing development has not at this time been assessed against any current or forecast economic conditions to support commercial viability".
