There is not enough detail in the photo to decide which species of wattle this is, though the leaflets are narrow enough and far enough apart to suggest Acacia decurrens rather than Acacia parramattensis. I presume you have also uploaded this as a bird sighting. If you could add a comment to each sighting with a link to the other, that would be very helpful to future users. Just click on the header southern-highlands.naturemapr.org at the top of the screen and the sighting number will appear. Then copy and paste.
