A new video shows Queensland's Environment Minister Leeanne Enoch telling a room full of people she has shed tears over the approval of Adani's Carmichael coal mine, while also saying current environmental legislation is flawed.

Key points: The mine is not named in the recording, but sources confirmed the speech was made about Adani

The new video sheds more light on Minister Leeanne Enoch's feelings towards the mine and also airs criticism of environmental legislation The footage appears to contradict comments Ms Enoch made about another video that emerged on Monday

The comments were in response to someone heckling Ms Enoch.

"I don't want to diminish anybody's feelings or thoughts with regards to this decision by the regulator — I think it is absolutely fair," Ms Enoch told an audience of hundreds at an environmental awards night in Cairns.

"Let me tell you, me personally, there have been some tears shed on this — very much.

"But my role will always be to uphold the regulator and I'll fight every day to make sure that the regulator is able to what they can do in this state — what they must do in this state — and hold those companies to account."

The recording comes after another video showed Ms Enoch telling a member of an activist group on Saturday she was "devastated" about the project.

The controversial mine is not specifically named in the latest recording, but sources at the event confirmed there was no doubt what the Minister was speaking about.

She refers to a project approved by the state's coordinator-general in 2014, which was when the Adani mine was first given the green light.

Her comments at the Cassowary Awards on Saturday night appear to contradict comments she made after the first video emerged on Monday.

In a statement in response to that video, Ms Enoch clarified she was not referring to her own feelings, but was instead devastated over the project's impact on traditional owners.

The new recording sheds more light on Ms Enoch's feelings towards the mine, and also shows her criticising the environmental legislation that saw it get the green light.

Environmental legislation flawed, Minister says

In the video, Ms Enoch also criticised current environmental legislation and vowed to defend the environmental regulator.

"The role of the Environment and Science Department has been to uphold the environmental conditions that were applied to that particular project," she said.

"There is no legislative power for a politician to intervene in environmental conditions — that is an absolute flaw in the legislation."

The room erupted into applause as Ms Enoch told the room she would devote time to working on those flaws.

But she also defended the role of the environmental regulator and vowed to "fight every day" to ensure it worked effectively.

"There's many people that don't like the outcome that the regulator arrived at, and that is where we're at," Ms Enoch said.

"The story now of course — my role is to ensure that the regulator can absolutely hold every single company in this state to account."

Ms Enoch said in a statement today that her comments on Saturday night "were about how this issue has divided traditional owners and the Queensland community".

"Understanding that this is an issue that people care a great deal about, I addressed the audience about the regulator's recent decision on the Carmichael mine project's groundwater plan," she said.

"I have shed tears over the offensive comments that have been directed at me and my family, and the division and heartache this one project has caused in the community, particularly amongst traditional owners.

"During Climate Week, I made it clear that Queensland is working on a Climate Transitions Options Green Paper that will help shape legislation in the future so that our laws, and the frameworks that regulators use to make decisions, are strengthened.

"The Morrison Government and its new Environment Minister need to review the Commonwealth Environment Protection and Biodiversity Conservation Act."

'Every Cabinet minister endorses the process'

After a backlash towards Labor in central Queensland over Adani in the federal election, Premier Annastacia Palaszczuk intervened by tasking the Queensland coordinator-general with brokering a speedier approval process by the Environment Department.

Ms Palaszczuk said her Government was united over the approvals process for the mine.

"The whole cabinet and the Government fully supports the processes that were set," Ms Palaszczuk said.

"And let me make it very clear, the whole cabinet supports jobs and regional jobs."

Police Minister Mark Ryan denied the controversial project had split the party.

"Not at all — we've always been on the same page when it comes to this project, that it has to stack up financially and environmentally, and there has to be a process followed," Mr Ryan said.

"All ministers, in fact, the Government supports the process and that process was followed."

'Complete and utter rabble'

Deputy Opposition Leader Tim Mander said the latest video was further evidence of a deeply divided Government.

"This proves that you cannot believe one word that this Premier says or this Government," Mr Mander said.

"They are contradicting each other, they are disunited, it is a complete and utter rabble.

"The Minister is criticising the legislation she is responsible for — it is beyond a joke."

Griffith University political analyst Paul Williams said the division could wreak havoc for the Government.

"Politically, this is potentially very explosive — it's no longer just a political he-said she-said, a slip-up recording," he said.

"Division is always death in politics.

"If Premier Palaszczuk and Minister Enoch cannot reconcile this difference, if the Cabinet can't appear to be unified, and if we suspect that there are other anti-Adani sympathisers in the Cabinet, well clearly the Cabinet is divided and that becomes a ticking time bomb for the Government," he said.
