This paper presents a broker diagnostic for improving the state of Aboriginal participation in the environmental planning and management of dryland areas. This paper draws on perspectives of individuals, referred to as Brokers, who are funded by government programs to manage the interface between Aboriginal communities and government agencies. Results from thirty-two interviews with a range of Brokers working at local, regional and Lake Eyre Basin scales are presented. We conclude that a broker diagnostic enables the analysis of the problems of integrated environmental governance and highlights how to improve Aboriginal participation in environmental management decisions and management programs.
