Camden County was one of the original Nineteen Counties in New South Wales and is now one of the 141 Cadastral divisions of New South Wales. It included the coastal area near Wollongong south to the Shoalhaven River, and also inland encompassing Berrima and Picton. Its western boundary was the Wollondilly River. The first settlement in the area was Camden Park, established by John Macarthur in 1806, just across the Nepean River from Cumberland County. It was the first land across the Nepean to be settled.
