CANBERRA, AAP – Prime Minister Scott Morrison has left the door open for a new coal-fired power station in Queensland, despite endorsing a new climate policy.

Launching his plan to achieve net-zero emissions by 2050 on Tuesday, Mr Morrison was asked about a feasibility study being conducted into a proposed coal-fired plant in Collinsville.

He said the study was due to be completed in June 2022.

“Any investments that people wish to make, well they have to meet the necessary planning and other regulatory approvals for them to go ahead,” Mr Morrison told reporters in Canberra.

“They have to make sense to them commercially and if they stack up, they stack up.”

He said the plant would need to meet environmental and other approvals.

“Legal investments in this country are still legal,” he said.
