St Marys is a suburb in western Sydney, in the state of New South Wales, Australia. It is 45 kilometres west of the Sydney central business district, in the local government area of the City of Penrith. St Marys sits between South Creek which forms the western boundary and Ropes Creek, its eastern boundary. History The township of St Marys was first known as South Creek. The Bennett coach and wagon works manufactured horse-drawn wagons to meet the growing demand for transport in Sydney. There is a Bennett wagon on display in South Creek Park (on the northern side of the Great Western Hwy, east of South Creek). The suburb is named after the parish church of St Mary Magdalene, built between 1837 and 1840 and situated between the Great Western Highway and King Street. The church foundation stone was laid on 22 November 1837 by Bishop Broughton. It is one of the oldest churches in New South Wales that still has regular services. The church is heritage-listed.

Other land grants in the area included those to Anna Josepha King in 1807 (Dunheved), Samuel Marsden (Mamre), and Mary Putland (Frogmore). The area was first called South Creek because European settlement was originally centred along the banks of the creek. The land grants became working holdings because of the permanent water supply. The rich alluvial soil along the banks of the creek ensured an expanding agricultural community and its location on what was then called the Great Western Road, later renamed to the Great Western Highway, meant that it became a convenient staging post. The name St Marys was first used when the St Mary's Post Office was opened on 1 October 1840. The township formed part of a grant to Mary Putland (later married Sir Maurice O'Connell), the daughter of Governor William Bligh (former master of , during the famous mutiny in
