Australia has given the green light to the expansion of an existing coal port at Abbot Point in Queensland.
It is said to be one of the largest coal expansion projects in the world.
The approval from the Department of Environment lists some conditions the project must achieve before going ahead, including how and where the sediment can be moved.
It includes dredging no more than 1.1 million cubic metres of spoil. It also excludes the disposal of dredge material offshore in the Great Barrier Reef Marine Park and Great Barrier Reef World Heritage property.
Earlier this year, UK bank Standard Chartered cut links with the energy firm in the expansion project.
