 The former Headmaster's Quarters was used as professional offices and the Main Building by the NSW Heritage Office (later the Heritage Division of the Office of Environment and Heritage).In 2011, the then-Labor state government negotiated the sale of 12% of the site to the Roman Catholic Diocese of Parramatta for $5.5 million, with the funds intended to go towards a major new arts precinct for Western Sydney to be established on the site.However, after the Labor government was defeated at the 2011 election, the incoming Liberal-National government cancelled the arts precinct in September 2011, labelling it an "unfunded promise".
