There are dozen very interesting trees from the Kimberley region with the potential of providing an income for remote indigenous communities. Research is being carried out on several different species that show promise from an initial analysis. Work is being carried out at the University of Queensland and Curtin University in WA.
Terminalia ferdinandiana, called Gubinge in the West Kimberley and Kakadu Plum in the NT is one that has had substantial work done on it's properties, and is being used for different purposes commercially already. More information on this genus can be seen here: at northwestplants
