Ralph Kelly - ICV 25: Fourth Speaker

Colonial Signal Flag of Port Jackson 

Ralph Kelly from Australia gave an insightful presentation signal flag evolution at Port Jackson, Australia.  Port Jackson is a part of Sydney waterway.  Ralph asserts that Nicholson's chart was foundational to vexillology.  As communication was lacking in the colonial period, flags were used as signals for the community to detail the composition of ships in Port Jackson.  Kelly showed that evolution of the code signals, eventually it was used to indicate weather as well.  An important place was Ft. Philip as a key signal station.
