 In the 1800s, John Blaxland built an original wooden weir at "Grove Farm" (now known as Wallacia) for a sandstone flour mill and additional brewery.The land was also used for wheat farming until 1861 when wheat rust infected the entire crop.The rural regions were chiefly one of dairying and grazing during the 19th century, but in the early 20th century - because of its rural atmosphere and proximity to Sydney - tourism developed as people opened their homes as guest houses.
