For many years prior to 1912, The Anglican Diocese of Newcastle’s office was located at Morpeth. The office building is still there in the grounds of St John’s Conference Centre.  In 1912, the Bishop moved to Newcastle and of course, so did the office.  Between 1912 and 1925 the office was located in various places in the inner city.  In 1925, the Diocese built Tyrrell House, at the very east end of Hunter Street and the office was housed there.

In 1981, the office moved to 250 Darby St Newcastle, to the old St. Hilda's Girls Hostel. This move took place because the Tyrell House site was redeveloped by the Church.  The office’s home was Darby Street until 1999 when staff temporarily moved to Closebourne House at Morpeth. This temporary move was in anticipation of a new office being built at the western end of the Cathedral. However, the new office never eventuated due to costs and planning issues preventing it.

The office moved back to more temporary offices in Hunter Street in 2001 and stayed there until January 2003 when staff moved to the current premises at 51 Newcomen Street.
