Bottlebrush (Callistemon) is another popular garden and small tree/shrub in flower at this time of year. They are a native plant that according to my flower book does occur naturally in the stream and swamp communities of the Blue Mountains but I have not seen any. My photo is of one of the many used in park and highway landscaping.
