Prior to
settlement and colonisation of Australia, the area that was to become known as Riverstone was inhabited by the
Darug tribe. Most of these people died due to introduced diseases following the arrival of the
First Fleet, and the remainder were largely relocated to government farms and a series of settlements.
18th & 19th centuries The Sydney Cove region originally settled in 1788 turned out to be unsuitable for farming, and after a number of years of near-famine in the colony, efforts were made to relocate food production inland to hopefully more climatically stable regions. In 1803 a government stock farm was established in what was to become the Riverstone/Marsden Park area, on the basis of the abundant water supply and good grazing land there. In 1804, the infamous
Castle Hill convict rebellion broke out in nearby Castle Hill. Those who took part in the armed convict uprising who then tried to escape to the Hawkesbury would have traversed the Riverstone district. In 1810, Lieut-Col
Maurice Charles O'Connell was granted 2,500 acres (10 km2) of land in the district, which he named "Riverston Farm", after his birthplace in Ireland. (The "e" at the end first appeared on railway timetables in the 1860s, an apparent misprint that has become the accepted spelling, although in the Sydney region the name is still pronounced as though the "e" is not present). Originally, beef cattle farmed in the area were driven overland to the
Hawkesbury River for transport by sailing ship to the convict settlement at
Sydney Cove. The construction of the Sydney to Richmond Railway line in 1864 both eliminated the need for this and opened up the region to non-rural development. In June 1867 the largest flood in record happened in Riverstone, with flood waters up to 19.7 metres.
20th century In November 1961 there was a major flood in Riverstone. Flood waters rose up to 15 metres at nearby
Windsor. On 9 October 1970, a major fire at the Riverstone Meatworks killed six men. The men were attempting to lead sheep to safety, when a wall collapsed and trapped them. It had been the second fire in the building in three months. In 1988, as part of a Federal Government programme to commemorate the 200th anniversary of European settlement in Australia, a heritage museum was established in the old Masonic hall.
21st century The suburb boundaries of Riverstone were changed in November 2020, shrinking the size of the suburb and creating the new suburbs of
Grantham Farm in the east and
Richards and
Angus in the west. The suburb also no longer extended into the
Hawkesbury local government area, with those areas absorbed into the suburb of
Vineyard. There was again major flooding in 2021, which saw some homes along Marsden Road become completely submerged. == Heritage listings ==
