Secondary forest pioneer species, usually in open scrub and grasslands on sunny places, below 1300 m elevation.
Planted as an ornamental in Australia. The fiber obtained from the inner bark of this species is used to make cordage throughout its range.
Australian Aborigines used the cordage for the construction of fish and kangaroo nets, while in Indonesia and the Philippines it is used for the
construction of ropes, and in Sumatra it is woven into mats. In the Bismarck Archipelago the fiber is used to make headbands and womens girdles.
As the trees grow quickly, the timber they produce is not strong but it is considered a good source for firewood.
