Comments:

The only Victorian species of about 30 Australian species. Mangrove forests provide important habitat as fish nurseries, bird nesting sites and intertidal zones for coastal animals such as crabs, shellfish and prawns. The wood of mangrove was used by indigenous people for making boomerangs, spears and digging sticks, while sap was used as medicine for treating headache, ulcers, stings and snake bite. Crushed leaves floated on water was used to stun fish.
