Fairly common. It grows almost exclusively on wattles. A large number of Cootamundra Wattles in the Castlemaine Township have Wire-leaf Mistletoe.It is a hemi-parasite; it relies on the host plant for water and minerals, but has chlorophyll and is able to make its own sugars and other carbohydrates.
In some parts of Castlemaine e.g. Hunter Track and Campbell Street, its host is Tree Lucerne.
