LEON CADOGAN 1899–1973. One of the foremost ethnographic experts in Paraguay. He was noted for his research on the origins, languages and customs of the Forest Indians of Eastern Paraguay. The son of an Australian immigrant belonging to the New Australia Co-Operative Society ... he was one of the first people to denounce the mistreatment of the Ache (one of the tribes) at the hands of the Mezito population. (Historical Dictionary of Paraguay, 1993)

It was perhaps a fair return because in 1893, when the first 200 Australian settlers took up the land given to them by the Paraguayan Government to establish their Utopian paradise, they found one thousand Guarani Indians living on the land. They were ‘expelled’.
