Greenough is a historical town 400 kilometres north of Perth, Western Australia and 24 kilometres south of Geraldton on the Brand Highway. The historic buildings are controlled by the National Trust of Australia. Another feature popular with tourists are the trees that are bent 90 degrees due to the coastal winds.
The mouth of the Greenough River is about 10 km to the north of the town.
On 16 February 1999, a rare annular solar eclipse of magnitude 0.9906 was visible from the area.
The area was first explored by George Grey in 1839 after which he named the area after Sir George Bellas Greenough, the president of the Royal Geographical Society in London. Grey claimed that the area could become the granary of Western Australia.
In 1851 Augustus Gregory surveyed 30,000 acres (120 km²) of land in the region which became known as the Greenough Flats. This was subdivided into 20- and lots with the view to encouraging English settlers who would be more used to the relatively small (by Australian standards) farm sizes. Within a few years it had developed into a highly successful wheat growing area and a population of over 1,000 from which a successful town developed.
A series of disasters starting with a major cyclone in 1872 and major flooding in 1888 as well as the discovery of gold in the goldfields caused the gradual decline and abandonment of the settlement so that by 1900 most of the settlers had left the area with many of the small farmlets converted to grazing. The town fell into disrepair until a tourism-based project in the 1980s helped refurbish many of the buildings.
In 1993, a woman and her three young children were brutally murdered in this small town. This tragic event featured on the Australian television show Crime Investigation Australia and is now known as the Greenough Family Massacre.
