Port Augusta is a small city in South Australia. Formerly a seaport, it is now a road traffic and railway junction city mainly located on the east coast of the Spencer Gulf immediately south of the gulf’s head and about 322 kilometres north of the state capital, Adelaide.  It is often called the “Crossroads of Australia” since it is at the intersection of the main north-south route between Adelaide and Darwin, and the east-west route between Sydney and Perth.
