Bermagui is a town on the south coast of New South Wales, Australia, in the Bega Valley Shire. It lies on the shores of the southern end of Horseshoe Bay. The name is derived from the Dyirringanj word, permageua, possibly meaning "canoe with paddles".

The Illawarra Steam Navigation Company was a shipping company that serviced the south coast of New South Wales, Australia from 1858 to the early 1950s. It was formed through the amalgamation of the General Steam Navigation Company, the Kiama Steam Navigation Company and the Shoalhaven Steam Navigation Company, each of whom serviced parts of the south coast with their respective vessels. After merging, the new company held a near monopoly in regard to shipping on the south coast, and their fleet visited every significant port between Sydney and the border of Victoria. The company transported both passengers and a range of produce, including livestock, and hence it became known as the 'Pig and Whistle Line': it was said that ships would wait an hour for a pig but not a minute for a passenger.
