"sixty-miler" MV Stephen Brown was donated by its owners, Coal and Allied, to the Australian Maritime College in Launceston, Tasmania, in April 1983. Most of the older "sixty-milers" had already gone to the breakers yard before then.Although local demand for coal was falling, demand in the export market increased particularly after the Oil Crises of 1973 and 1979. In 1967, the Ball's Head Coal Loader, reopened as an export trans-shipment terminal. In 1976, the cable loading system was replaced by a system of conveyor belts capable of loading at 1,000 tonnes per hour. A comparison of photographs, from the 1920s and late 1970s, shows that the gantry unloading crane was either extensively modified or completely replaced at some point. After 1990, most of the coal moved by the few remaining "sixty-milers" was destined for export. The last "sixty-miler" to carry coal to Sydney—the MV Camira built in 1980—ceased operating the run around 1993, with the final closure of the Ball's Head Coal Loader in that year marking the effective end of the coastal coal-carrying trade to Sydney. The MV Camira was sold in 1993 and converted to a livestock carrier. During the 1980s, the development of Newcastle as a bulk coal export port resulted in a revival of coastal coal shipping, this time to Newcastle. Purpose-built in 1986, a new self-discharging collier the MV Wallarah—the fourth collier to bear the name and, at 5,717 gross tonnage, far larger than a true 'sixty-miler'—carried coal from Catherine Hill Bay to Newcastle, where it was unloaded for export at the Port Waratah Coal Loader, Carrington. This last echo of the coastal coal-carrying trade ended on 22 July 2002. Remnants The Dyke and the Basin are still part of the enlarged Port of Newcastle. The last of the hydraulic cranes at The Basin were demolished in 1967 to make way for a modern export coal-loader but the bases for fixed cranes 7, 8, 9 and 10 survive. The associated Carrington Pump House building still survives in Bourke St Carrington, although its equipment was removed and its chimneys demolished long ago. Morpeth is now a picturesque riverside town; the decline of the port and other local industries has resulted in the preservation of many of its 19th-Century buildings. The wharves and most of the port's warehouses are gone. The Outer Harbour at Port Kembla and its breakwaters remain, as a part of an enlarged port
