The brilliant colour of the fruit is quite remarkable, I can think of few wild foods that are so colourful. Especially being blue, it is not often you see blue fruit in the wild!

The trees themselves are classified as a rainforest tree, and they possess impressive buttress roots.
Bunya Nuts
Another traditional food in this region are the Bunya nuts. They were associated with large inter-tribal gatherings and feasts, as the Bunya Pine drops massive pine cones the size of a basketball in great quantities at certain times of the year, which could easily feed large groups. The cones themselves are extremely heavy, and therefore a serious danger to those standing beneath the tree. For this reason, city councils often cut the cones form the trees before they can mature and drop on someones head!
