There are thousands of Aboriginal engraving and shelter art sites recorded around Gosford and across the Central Coast region. These rock art sites include animals, birds, sea creatures, bird tracks, human footsteps, male and female figures, hunting weapons and ancestral beings. Many of the sites were documented by W. D. Campbell in 1899, and later by Fred McCarthy and Ian Sim. Many sites are protected in the national parks of the Central Coast, but a large number of recorded sites are on rural properties and industrial estates.
A significant site near Bulgandry in Kariong: "The whole group is particularly well drawn, and presents one of the best samples of this native art that the Writer has met with"
