Macadamia nuts grow encased in a hard, woody shell, which is protected by a green-brown fibrous husk. In its natural state a macadamia tree will have flowers, nutlets and mature nuts growing simultaneously, in profusion for much of the year. The nuts fall to the ground between March and September each year and are harvested by pin wheel harvesters at regular intervals.
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.
