The Mater Dei site adjoins Harrington Grove to the west of Macquarie Grove Road (Figure 5-1).  It constitutes the northern portion of a larger site which is occupied by the heritage listed building called Wivenhoe, a functioning school, conference centre and collection of associated buildings. The site is bound to the east by Macquarie Grove Road, to the north by Cobbitty Road and to the west by the eastern edge of the access driveway to Wivenhoe and the remainder of the Mater Dei site.
