Course and features
Toongabbie Creek rises in the north-western suburbs of Sydney, west of the Old Northern Road, within the suburb of Castle Hill; with its headwaters forming the watershed boundary between the Hornsby Plateau and the Cumberland Plain. The creek flows generally south-west, then south by east, then south by west, then east before reaching its confluence with the Darling Mills Creek to form the Parramatta River, in the suburb of North Parramatta, in land adjoining the northern boundary of the Cumberland Hospital. The course of the creek is approximately 9 kilometres (5.6 mi).
Although only a small portion of Toongabbie Creek is contained within the Blacktown local government area, much of its sub-catchment, including the Blacktown and Lalor creeks and their associated tributaries are within the City of Blacktown. In 2005, the Toongabbie Creek catchment area was rated as the highest polluting catchment out of the twenty-two catchments in Blacktown. Much of the creek is channeled in a concrete drain; and domestic garbage is often scattered along the creek's banks. Prior to April 2015, the creek was dammed at many places by fallen trees, and the rapids at Mons Road were not visible. The stagnant water in the dams was bubbly. After the rain in April 2015, which caused a flood that damaged infrastructure at Parramatta, most of the dead trees were cleaned away and the rocks at Mons Road are now exposed.
The land adjacent to the Parramatta River and its tributaries, including the Toongabbie Creek, was occupied for many thousands of years by the Burramattagal, Toongagal, Wallumattagal, Wangal, and Wategora Aboriginal peoples. They used the river as an important source of food and a place for trade.
