Earlier this year, Hunt was given an award at the World Government Summit in the United Arab Emirates for his role in axing the carbon tax. Turnbull has taken the environment minister role from him, giving him the portfolio of industry, innovation and science.
The new environment minister is Josh Frydenberg, who will also pick up the energy portfolio in what could be considered conflicting areas of public policy.
"Can I say that Mr Hunt has been an outstanding environment minister and he served in that portfolio in government and, indeed, in opposition," said Turnbull.
Last year, Frydenberg as resources minister said there was a "strong moral case [for coal mining] that the green activists sometimes don’t comprehend".
