High Quality Content by WIKIPEDIA articles! 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 become 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.
