Westmead is located 26 kilometres west of the Sydney central business district, in the local governement area of the City of Parramatta.
With the British settlement of Parramatta, Westmead was originally part of the domain of Government House. What is left of this domain, including Government House, form Parramatta Park. The name Westmead came into use when the governor’s domain was first subdivided in 1859. The subdivision of the domain was completed in 1889. The Northern Meadow and Western Meadow of the domain were split off and called Northmead and Westmead. From this time orchards were established by many new settlers, including some whose names were well-known in the Parramatta area – George Oakes, Nat Payten and William Fullagar among them.
Parramatta Marist School was established by Fr. John Therry in Hunter Street Parramatta in 1820, under the direction of Mr. George Morley. The school was transferred to the site of the present junior school in 1837 and entrusted to the care of the Marist Brothers in 1875. This makes Parramatta Marist the oldest Catholic school in Australia.
