Watanobbi is about 70 kms north-northeast of
NSW's capital city of Sydney. In the 2011

Although many believed the name's origin was
Aboriginal, with the Wyong Shire originally
claiming it meant "hills surrounded by water",
the Geographic Names Board later confirmed
there was no Aboriginal significance to the
name, with the two most likely sources being a
corruption of the Japanese surname
Watanabe, ascribed to a friend of well-travelled
pioneer Albert Warner, or a comment made by
early landowner Allan Chapman about the
"nobby" shape of the surrounding terrain, have
been suggested. Landowners, claiming they
were the butt of rude jokes and that the
suburb's house prices had remained static
relative to other areas, attempted
unsuccessfully to have the name changed to
Chapman Gardens in early 2002
