In the early days of the colony, the hill behind old Government House had been named ‘Rose Hill’ by GovernorArthur Phillip, before the suburb had been namedParramatta.
On 25 March 1789, Henry Dodd took charge of a farm established at Rose Hill.[2]James Ruse came to farm there in November of the same year.[3] In December 1790, a crop of corn (wheat), described as "exceeding good," was harvested at Rose Hill.[4] By 1791, 200 acres of land had been cleared and were in production.[5]
Nearly a hundred years later in 1883, 850 acres (3.4 km2) ofJohn Macarthur'sElizabeth Farm were subdivided for industrial purposes. Part of the estate was set aside for a recreation area, which becameRosehill Racecourse.
A public school opened here in 1886 and the railway station opened in 1888 on theCarlingford railway line, which was privately owned until it was taken over by the state government in 1904 and later closed in January 2020.[6]
