Hempbush, Gynatrix pulchella, doesn’t have those rusty hairs and has finely crenate leaves. See http://plantnet.rbgsyd.nsw.gov.au/cgi-bin/NSWfl.pl?page=nswfl&lvl=sp&name=Gynatrix~pulchella
Possibly Pomaderris, as Rainer suggested. Wait till it flowers, and then create a second sighting, with the copied and pasted URL of this one in the Comments field, to provide a timeline.
