Coal workers feel looked down on, something that was evident at the last election, the prime minister will say in a speech to the Queensland Chamber of Commerce.

"That debate has been done in the coalition and it is resolved and our policy was set out very clearly. (Net zero) has the strong support of the government," he said.
"We did the hard yards to get everyone together and of course, there'll be some who disagreed at the time and I suspect they still will, but that doesn't change the government's policy."
