[1][3] The Kamilaroi had a reputation as fierce warriors who defended their familial hunting grounds from other intruding bands and who also actively resisted European settlement for many years.
[1][4] The opening up of the Upper Hunter and Liverpool Plains area was facilitated in the first instance by explorers Benjamin Singleton and John Howe in 1818 and again in 1821.
Bigge recommended that private investment and enterprise, possibly in the growing of fine wool, was a crucial measure in the viable future of the Colony of NSW.
Surveyor General John Oxley was consulted on the possible location of land suitable for growing fine wool.
[1][7]: 22–30 In the first years of its operation the AACo struggled to establish its ambitious enterprise and this was not helped by the fact that the land at Port Stephens was not particularly suitable for raising sheep.
[1] The pressure for closer settlement brought to bear on Warrah Station at the turn of the century and the eastern part of the run around Willow Tree was subdivided in 1908.
In 1969 the Warrah homestead was sold and the company interests in the area comprised approximately 13,000 hectares (33,000 acres) on Windy Station in the north west corner of the original grant.
The entire structure, shearing shed, wool room and sweating pens were constructed of timber with a corrugated iron roof.
The upright members of the wool room and shearing shed are cut from single trees and extend from the foundation piers through to the roof.
[1] The shearing shed was constructed with a mechanised board powered by a steam engine located adjacent to the northern wall of the wool room evidence of which is still in situ.
[1] The building is in generally good condition for its age, although there is evidence of extensive deterioration of the bases of posts below the wool potential: room.
[1] As at 21 April 2015, Windy Station Woolshed is of state heritage significance for its historical role in the development of the fine wool industry the colony of NSW and its association with the Australian Agricultural Company (AACo), the colony's first private enterprise established with the aim of developing the fine wool industry in NSW.
[1] The Windy Station Woolshed's state heritage significance is enhanced through its association with the outstanding AACo superintendent Jesse Gregson who was also a noted amateur Botanist who contributed greatly to the Botanic Gardens National Herbarium of NSW.
[1] Windy Station Woolshed is of state significance for its research potential as its extensive extant fabric coupled with the overall design facilitating an efficient process flow layout and incorporating an efficiently designed mechanised shearing board clearly demonstrates the working of an productive and high quality early 20th Century woolshed set up to process fine wool.
Windy Station Woolshed is of state heritage significance because it represents the achievement of a technological high point in the AACo s development of a fine wool enterprise in New South Wales.
The Windy Station Woolshed's state heritage significance is enhanced through its direct associations with the AACo and its objective of developing a fine wool industry in NSW.
It also has associations with the outstanding AACo superintendent Jesse Gregson, who was also a noted amateur Botanist who contributed greatly to the Botanic Gardens National Herbarium of NSW.
Windy Station Woolshed is of state heritage significance for its aesthetic qualities as a majestic example of Federation Carpenter architecture.
Its surviving fabric includes most of the working components of a hydraulic dumping press and archaeological evidence of three phases of power transmission technology as well as its mechanised shearing apparatus.
It is of state heritage significance as a rare and intact example of a large and efficient woolshed with material evidence of its original equipment and fit-out.
Its finessed layout to promote the flow of work processes through the shed and attention to airflow through the building via the clerestory structure make it almost unique in NSW.
