documentation of this was in 1857, by Lieutenant Chimmo of the HMSV Torch writing of the ship names in the 'Post Office Cave'. The island became a stopping point for water and repairs for sailors traversing the Torres Strait in trading ships, and government ships from the early days of European colonisation, and many left their marks both alongside and overwriting the Indigenous rock art. The recollections of lighthouse keepers and their families in newspaper articles and books never fail to mention the painted caves, and some of their names also appear amongst the graffiti. The Indigenous rock art and graffiti was photographed by a Queensland Museum team in the 1980s and 1990s, and subsequent studies have shown that there are marks left by: Indigenous visitors/occupants including depictions of sea creatures passing ships from as early as 1841 individuals on the ships lighthouse keepers, their families and visitors (including a lighthouse inspector) Military personnel living on the island during WWII, members of a signals unit monitoring the Pacific.
