Also found in Western Australia, Northern Territory, Queensland and New South Wales.

Seed collecting:
Collect capsules that are maturing, turning brown and contain hard seeds inside. 
Seed cleaning:
Place the capsules in a tray and leave to dry for one to two weeks. Then rub the capsules gently by hand or with a rubber bung to dislodge the seeds. Use a sieve to separate the unwanted material. Store the seeds with a desiccant such as dried silica beads or dry rice, in an air tight container in a cool and dry place.
