In the early days of British settlement in New South Wales, the main activity was cutting down the tall trees which grew there. The Wahroonga area was first settled in 1822 by Thomas Hyndes, a convict who became a wealthy landowner. Later there were many orchards, and when the railway was built it became a popular place for businessmen to build out-of-town residences with large gardens in the 1920s and 1930s.
