Aboriginal (Ngunnawal) uses

The flower spike soaked in water makes a sweet drink.[3] The growing part of the leaf stem and the white leaf bases can be eaten.[3] The dried flower stems form a base for fire drills when making a fire.[3] The resin from the base of the leaves is a glue used when making weapons and axes.[3]
