Arthur reported to the Colonial Office secretary in London that the Aboriginal people "already complained that the white people have taken possession of their country, encroached upon their hunting grounds, and destroyed their natural food, the kangaroo" and in a memo he proposed settling the Aboriginal people "in some remote quarter of the island, which should be reserved strictly for them, and to supply them with food and clothing, and afford them protection ... on condition of their confining themselves peaceably to certain limits". He said Tasmania's northeast coast was the preferred location for such a reserve and suggested they remain there "until their habits shall become more civilised". He pursued the proposal by issuing on 19 April 1828 a "Proclamation Separating the Aborigines from the White Inhabitants" that divided the island into two parts to regulate and restrict contact between blacks and whites.
