Port Giles is the newest port on Yorke Peninsula in South Australia, between Stansbury and Edithburgh. Port Giles is not a town, but simply a large jetty equipped for bulk handling of grain, operated by Flinders Ports, and a similarly large grain storage facility operated by AusBulk. It was opened by the then Premier of South Australia, Steele Hall in 1970, and led to the closure of many of the smaller ports on the peninsula. Port Giles was deliberately built to be able to handle bulk grain, and load it onto larger modern ships. Many of the other ports were not deep enough for larger ships, and could only be serviced by small ketches and coastal steamships. They only handled grain in bags, not in bulk.
