The port has a combined import and export cargo capacity of more than 6 million tonnes per year, yet trade sits at about half this level.

North Queensland Bulk Ports said it was committed to investing in and upgrading port facilities and working with customers to progress trade opportunities to facilitate greater use of the port.

"With around $1.3 billion in state and Commonwealth funding from now to the end of 2022 committed to road infrastructure upgrades in the Mackay region, the efficiency of the transport corridors between the port, Mackay region, Central Highlands and Whitsundays will enjoy significant improvements," it said.

"We are actively pursuing growth opportunities at our ports, including planning, obtaining approvals for, and undertaking initial development works on the next Mackay industrial precinct expansion area."

Land areas behind the port already accommodate more than 50 industrial and commercial businesses with more than 155 hectares of land under lease. About 250 hectares of vacant land is available for development.

"This property represents a large land bank we can use to meet regional industry demands well into the future," it said.
