Bird attracting. The fruit is a favourite food of fig birds and fruit pigeons. Also eaten by cassowaries.

Colour of fruits are not from anthocyanins, but from layered filters to create patterns of light interference. Rare in plants, but more common in insects.

Fruit stones were used by Aboriginal people for necklaces. Aboriginal people of the north were known to make up an edible paste of the ripe fruit by squashing them into a bark trough filled with water.

Prefers moist, well drained soil in full to partial sun. Germination of the seed is slow with a low strike rate.

The wood is easy to glue and stain and is very suitable for bent work. It is used for plywood, veneers, furniture, joinery, racing oars and boat planking.
