Acacia parramattensis

Acacia parramattensis, commonly known as Parramatta wattle, is a tree of the family Fabaceae native to the Blue Mountains and surrounding regions of New South Wales. It is a tall shrub or tree to about 15 m (49 ft) in height with phyllodes (flattened leaf stalks) instead of true leaves. These are finely divided bipinnate . The yellow flowers appear over summer. It generally grows in woodland or dry sclerophyll forest on alluvial or shale-based soils, generally with some clay content. A fast-growing plant, it regenerates after bushfire by seed or suckering and can quickly colonise disturbed areas. Likewise it adapts readily to cultivation and is used in revegetation projects....read more on Wikipedia.
