TypeBeachDetailsIn Broken Bay immediately to the east of Flint and Steel Point. Also shown as White Horse Beach. It is said there was a house there in the 1920s and the owner sometimes exercised a white horse on the beach. Flint and Steel Beach is mentioned by Surveyor Larmer in 1832 as already being named as such. The origin of the name could possibly be connected with the shape of this feature. Flint and steel struck together produce sparks, and could be used to ignite gunpowder.
