In 2020, researchers at the University of Queensland were researching a fruit native to Arnhem Land in the Northern Territory, "Buchanania obovata", known as the green plum. Eaten for more than 53,000 years but previously little-known among non-Indigenous people, the scientists learnt about the plum from people at the remote community of Yirrkala. It is harvested some time after the Kakadu plum harvests. Nutritional analysis showed high levels of protein, dietary fibre and the minerals potassium, phosphorus and magnesium. In addition, the folate level is among the highest of commercially available fruits. Its potential as a commercial crop for Indigenous communities is being investigated.
