"Owned and operated by Tasmanians for Tasmanians," says the website of the Tasmanian Ports Corporation. It's owned by the Tasmanian state government and, the website says "Over 99% of Tasmania's freight moves through our ports." In fact, TasPorts operates all but one port in Northern Tasmania. The Australian Consumer and Competition Commission thinks that TasPorts tried to stop a company entering the pilotage and towing business with a view to lessening competition. It's the first test of a 2017 version of an existing law.
