Joseph Harrison, who had married Mary Ann Thompson, settled on a block in the area in 1839, planted orchards and built a small timber cottage they called "Cherrybrook Cottage". The name "Cherrybrook" is believed to have come from the fact they grew cherry trees near the creek, which passed through their land. Their 65-acre (260,000 m2) block, which became known as "Cherrybrook Farm", had been granted originally to Mary Russell during the 1820s. The orchards here produced peaches, apricots, pears, plums, and citrus fruit. Many years later the property was bought by Eric Vaux, who established a dairy and kept the name Cherrybrook.[citation needed]

In February 1959, the land was subdivided to become the first project home village in Sydney. The original bushland was bulldozed, and exhibition homes were built on cut and fill sites, then landscaped. Accelerated development occurred again in the remaining rural areas in the 1980s, and Cherrybrook Post Office opened on 20 July 1994.  (Wikipedia)
