Port Giles is not a town, but a port facility consisting of a large jetty equipped for bulk handling of grain which is operated by Flinders Ports, and a similarly large grain storage facility operated by Viterra. 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 can handle Panamax size ships or larger.
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.
The majority of Yorke Peninsula's wheat and barley crop is shipped out of Port Giles. (wheat and barley from Viterra's Ardrossan site is transported via road to Port Giles for export) In recent years, Port Giles has also accepted canola deliveries. While the site is relatively quite most of year, during the harvest season (Nov-Jan) the site very busy with long queues of trucks waiting to unload.
