The timber industry has been a major influence of the Wyong Valley since the 1800’s.  During the 1820s, timber getters came into the Valley to fell cedar, forest oak and rarer rainforest trees.  This practice occurred in both the Dooralong (since the 1820s) and Yarramalong (since the 1830s) valleys, with timber often being shipped to Sydney.  By the 1880s, there were three timber mills operating in the Yarramalong Valley producing rims for wagon wheels, fruit cases and house timber.

The timber industry also opened up the valleys and attracted farmers and settlers who cleared the river flats in the 1850s.  Dairy farming was also a major industry in 1930s, peaking 40 years later when there were roughly 100 operational dairies in the area.  However, dairy farming declined in the 1980s, and by 1995/6 no dairy farms were operational in the Wyong Valley.  Poultry farming remained a smaller industry, which peaked in the 1960s.

An assessment of non-indigenous heritage has been undertaken as part of the Environmental Assessment studies.  Several surveys have been undertaken since 1999 in both the surface facilities areas and within the mine footprint. A number of possible items of heritage importance were noted during these studies however no items of national or State significance lie within the impact area of the Project.

Although the Project will not impact on any State significant heritage items and will be designed to safeguard items of local heritage significance, further assessment will be undertaken within the mining area as part of the ongiong Subsidence Management Plan process.
