🇦🇺 Callaghan, Australia

Callaghan is a suburb of Newcastle in New South Wales, Australia. It is primarily known for being the location of the University of Newcastle's main campus. While it doesn't have any ports, shipyards, or factories producing ship parts, seafarers, shipowners, and crewing companies may find the city of interest due to its proximity to the Port of Newcastle, which is one of Australia's largest coal exporting ports and handles a significant amount of international trade.
