Mr Morrison rebuked "senators listening to themselves" on the coal project after Queensland Liberal senator James McGrath put pressure on Environment Minister Melissa Price to issue the approval.
The Morrison government has moved to end a damaging split over the Adani coal mine and granted the controversial project its final Commonwealth environmental approval.
Despite the Federal Government's insistence that the project won't irrevocably mess up groundwater in Queensland's Galilee Basin, opponents have slammed the decision as a concession to mega-polluters and an insult to climate change realists.
"Throughout the past 18 months, the Federal Department provided us with certainty of process and timing, including the steps involved in the independent review by CSIRO and Geoscience Australia experts".
The government has given the green light to the groundwater plan for Adani's Carmichael mine.
The Groundwater Dependent Ecosystem Management Plan (GDEMP) is one of the two outstanding management plans that require approval from the Queensland Government to allow Adani to start construction and mining.
The last remaining management plan Adani still needs to secure concerns a local and protected bird species in the region, the black-throated finch.
Geoscience and CSIRO identified areas of improvement including the Doongmabulla Springs for a better protection of the surrounding environment, an advice which Adani has "accepted in full", according to Price.
Now, Adani plans to letter drop thousands of homes in the state's north, touting the number of jobs its project will create and challenging the state government on its approvals process. So far only 16 of 25 environmental plans have been finalised or approved by the Commonwealth and Queensland with nine more to be finalised.
"It's time the Queensland government gave us a fair go and stopped shifting the goal posts so we can get on with delivering these jobs".
"The project has been under the scrutiny of government agencies in Brisbane and Canberra under both sides of politics over the last nine years", the QRC said in a statement.
Environmental lobby group, Lock the Gate Alliance, wants the decision to be investigated.
Leeanne Enoch's environment department will need to sign off on Adani's groundwater plan.
"And, importantly, Adani does not have federal approval for the proposed above-ground water infrastructure it requires to support its proposed thirsty coal mine", Slattery said.
