Australia need not only expedite new construction as well as expansion of varied mining infrastructure pipeline projects such as road, rail and port projects, but also ensure to manage them well in the light of expected surge in the demand of commodities.

A report by the federal Bureau of Resources and Energy Economic (BREE) released Monday said Australia's export volumes of coal, iron ore and liquefied natural gas (LNG) are expected to grow significantly in the future.

Main contributors to Australia's energy and resources exports, combined together, the three commodities have been estimated to surpass A$200 billion in fiscal 2012-13.

However, while the resources are just there lying around the tiny island-nation, "managing the completion of the projects is critical to reap the benefits of what is expected to be continuing strong growth in commodities and Australia's position in it," the Herald Sun quoted Simon Crean, Regional Development minister, as saying in Canberra on Monday.

"If we are going to maintain the efficiency, maintain that competitive edge, we have got to keep investing in capacity and in the infrastructure," he said.

The BREE said exports of Australian thermal coals will jump between 267 and 383 million tonnes by 2025, while metallurgical coal exports will grow between 260 and 306 million tonnes.

Iron ore, meanwhile, will be between 885 million and 1.08 billion tonnes, and LNG by between 86 and 130 million tonnes.

"For the medium to long term, planned infrastructure is more than adequate to meet growth to 2025, but it's got to be managed in a planned way," Crean said. "Australia's strength in many ways isn't just the fact that we have the resources, it's the efficiency with which we extract them and ship them."
