Bunya Nuts are native to south-eastern Queensland especially the Bunya Mountains National Park. The bunya nut tree is a huge tree which bears a crop only after the tree itself is around 100 years old, and then it crops once every 2 or 3 years only. Football-sized green bunya pine cones are hidden in the tree canopy weighing  5-10 kilograms and containing between 30 and 100 nuts. The cones will fall from the tree when mature and should be harvested and frozen or processed within a week.
