Perhaps better known as an entomologist/zoologist, Hill was an all-round naturalist and collector. He collected in north-western Australia in 1909-1910, and in 1911-1912 was a member of Captain H.V.Barclay's expedition to the Macarthur River and the Gulf of Carpentaria. These latter collections formed much of the basis for Ewart & Davies' The Flora of the Northern Territory (1917). Hill's collections were acquired by Ewart through both donation and purchase, and are now at MEL, with duplicates in NSW.
