The cache has been re-hidden today at the grave site of Thomas Lucas, a ticket of leave convict who was one of the first European settlers on the Southern Moreton Bay Islands. He lived on the Islands from 1853 to 1893, when he passed away.

Thomas Lucas lived at Corroboree Point for many years, and also set up as an oyster getter on Karragarra Island. He became a major land owner of Lamb Island in the late 1880s.

His grave lies just above the jetty on Lamb Island, the only known grave on the island. The main road on Lamb Island is named for him.
