Named after John Oxley (1784-1828) the explorer, who, in 1823 was granted 600 acres in the St Marys area, which is now the present site of Oxley Park. The grant extended from Queen Street east to Ropes Creek and from the Great Western Highway to the railway line. Oxley never lived there nor was any homestead built there for occasional stays. It was most probably used as a cattle run. Oxley owned other properties near Minto, Appin and Bowral and resided at “Kirkham” near Camden, where he died in 1828. After the death of John Oxley, his property at St. Marys was purchased by Phillip Parker King. Anna Josepha King, Phillip’s mother chose a site on this land for the St Mary Magdalene Anglican Church. After World War One this land was subdivided into five acre lots and named Oxley Park.
