QRC chief executive Ian Macfarlane said in Mackay that the resources sector supported 38,200 jobs, which was 61% of total local employment, and contributed $7.3 billion to the city's economy.

"The Palaszczuk government's snap decision last year to impose the world's highest royalty taxes on coal producers is a serious threat to companies investing in resources projects that will provide the jobs and economic contribution regional areas need to secure their future," he said.

"We are taking that message direct to homes in each of these cities, so people know exactly what's at stake as the coal royalty tax increase pushes resources investment to other states and countries with much lower royalty tax regimes."

In Rockhampton, the resources sector supports 10,500 jobs, which is 36% of the total local employment and contributes $1.9 billion to the city's economy.

In Townsville, the resources sector supports 7100 local jobs and contributes $1.1 billion to the city's economy.

"We encourage people to keep an eye out for the material that will be delivered to letterboxes to explain just how high the new royalty taxes are compared to our main competitors for investors, and the negative impact they are having," Macfarlane said.

"Thanks to the hard-working men and women working at mines and gas fields across Queensland, the resources sector kept the state's economy strong during the global challenges of recent years, and last financial year contributed a record $94.6 billion."

Macfarlane said the QRC wanted people living in Rockhampton, Mackay and Townsville to be involved in the conversation about the future of the resources sector, so the coal industry could continue to support regional jobs and economies.
