W.D. Campbell recorded and sketched about 250 Aboriginal rock art sites across Sydney across nine parishes (predominantly engraving sites). A number of the coastal and what are now inner-city sites have been lost to development and weathering, but many of the engravings are still in good condition.
The Wheeler Heights Aboriginal Site is large site documented by W.D. Campbell in 1899, who described it as “one of the finest groups the Writer has come across”. The scenes include two men fighting and a successful kangaroo hunt.
