Woorike (Koori name) was classified as in the Genus "Banksia" after Joseph Banks and "marginata" from Latin marginatus; bordered, referring to recurved leaf margins on some forms.Association of Societies for Growing Australian Plants (ASGAP) Banksia marginata
B. marginata does have some characteristics found throughout the species: it always has finely-toothed long foliage with a dark green upper surface and a silvery reverse; it is not tolerant of high-phosphorus soils or waterlogging; and it tends to be tolerant of dry soils. In most situations, it can form a dense shrub that will flourish in full sun to semi-shade with flowering from early spring through to autumn.- Metropolitan Tree Growers Pty Ltd

They have been there for a while and seemed not to be doing any harm to the tree or the neighbours.
