Badgerys Creek is named after James Badgery who received a grant of 640acres in 1812. Badgery (1769-1827) had arrived in the colony in November 1799 as an emigrant in the employ of William Paterson of the New South Wales Corps. In 1803, Badgery obtained a grant of 100acres at in the area of Yarramundi Lagoon and an additional 39acres was granted the following year. However it was this large grant of 640acres that Badgery used to establish a farming enterprise which included property in the region and evolved over the nineteenth century into the agricultural company Pitt Son & Badgery. Badgery named the grant Exeter Farm after his English birthplace. By 1828 the Badgery family had 1900acres of land in the colony. Essentially rural and sparsely populated throughout the nineteenth century, local government representation was forced on the area by the New South Wales Government in 1906 through the establishment of Nepean Shire. In the early 1920s, Badgery’s old grant was divided under the provisions of the Soldier Settlement Act, while in 1936 a large area with frontage to South Creek was acquired by the Commonwealth of Australia for a CSIRO research station for animal health (McMaster’s Field Station) and also for a short time was a field station for research into radio astronomy. The site was sold by the CSIRO in 1996.[1]
