The Coastal coal-carrying trade of New South Wales involved the shipping of coal—mainly for local consumption but also for export or coal bunkering—by sea to Sydney from the northern and southern coal fields of New South Wales. It took place in the 19th and 20th centuries. It should not be confused with the export coal trade, which still exists today. There was also an interstate trade, carrying coal and coke to other Australian states that did not have local sources of black coal.
