Uses

Building material

Ornamental brushwood fencing comprising the grey stems, twigs and dry foliage of ''Melaleuca uncinata'' has been in use in Australia for more than 80 years. It is an important market for melaleucas although representing only 1% of the fencing market in Western Australia. Other uses include the manufacture of garden furniture, gazebos and hanging baskets. About 600,000 bundles of brushwood, each about were used in Australia in 1994 with a predicted annual market growth of 5.5%.

Essential oils

The leaves of this species have been analysed for their oil content. There appears to be different types of oil collected from two groups of plants. One group contained 1,8-cineole as its major component and the other terpinen-4-ol.
