The Courier-Mail says documents obtained through freedom of information show public servants were subjected to government demands that two projects be approved within weeks of each other.
The documents showed that as the $18 billion Santos GLNG project was nearing approval in May 2010, public servants were hit with government demands to deal also with the $16 billion QGC project and then the Origin-led APLNG proposal, approved in November of the same year.
The newspaper also said that just days before the QGC approval was granted, public servants had warned the government's assessment team they still had not been given detailed information on pipelines and the location of wells.
They had also warned a long list of environmental issues had not been fully analysed.
The documents show public servants believed they needed to provide a "bankable outcome", even without all the information that normally would be necessary for the government to grant approvals.
Mr Newman told reporters on Monday he was concerned about the CSG approval process and would refer the issue to the Crime and Misconduct Commission (CMC) himself if Close The Gate activist Drew Hutton did not.
"I have no reason to believe that anything has been done in a bad way, a detrimental way to the environment," he said.
"But in terms of the process and what may or may not have happened, well, Drew Hutton is right to raise those concerns.
"I share those concerns. I think the CMC should be looking at it."
Australia's peak gas body says environmental review processes for both projects were thorough.
"We provided every bit of information that we were asked for," Australian Petroleum Production and Exploration Association spokesman Rick Wilkinson told the ABC.
"That's all we can and should be able to do from our side of the fence," he said.
Lockyer appeared last week as the celebrity spearhead of APLNG's new TV and newspaper advertising campaign.
His contract is rumoured to be "north of a six-figure sum over three years", SBCT alleges.
"The science is untried and uncertain even at a world level, and yet here we have Lockyer coming out in an advertising campaign spruiking the benefits of CSG," he said in a statement.
"The mind boggles."
Comment is being sought from Darren Lockyer.
