 A number of small wordlists were recorded in the early days of the Swan River Colony, for example Robert Menli Lyon's 1833 publication "A Glance at the Manners and Language of Aboriginal Inhabitants of Western Australia".Lyon acquired much of his information from Yagan while Yagan was incarcerated on Carnac Island.Despite the significance of Lyons work in being the first of its kind, George Fletcher Moore diary republished in 1884 described Lyons work as "containing many inaccuracies and much that was fanciful".
