Harrington Park) as a single entity. The Swans upgraded the sections of Orielton's farm buildings and then allowed the Department of Defence to make the homestead liveable for their occupation, from 1942 to 1943. During World War II the Camden district was the scene of much military activity, and Orielton was occupied by the army for training and residential purposes. Post World War II Since 1944 Orielton has been owned by the Fairfax family who also own neighbouring Harrington Park. The Fairfax family resided at Harrington Park and Orielton was managed as part of the Harrington Park estate. Orielton was important in Sir Warwick Oswald Fairfax's pursuit of breeding Stud Hereford cattle. The yarding, sheds and paddocks were modified to cater for the extensive breeding program he undertook. He set Orielton up as his holding and breeding centre for Harrington Park Poll Hereford stud. Fencing, paddocks and shelters were established to raise and manage stud livestock. The steam mill appears to have been pulled down during this initial period of occupation. During this period, the property was an outstation with tenants occupying Orielton house. A dam visible in a 1947 aerial photograph south-west of the homestead was expanded by Fairfax , across the western boundary of the former picking garden and orchard. In the 1960s Warwick Fairfax was knighted, Orielton's windows were boarded up and some parts of the estate were used for goat farming. Realignment of The Northern Road to the east in the 1970s including a new bridge over Narellan Creek east of the previous one, led to the cutting off of Orielton's (south-eastern-running) main drive (towards Narellan Creek). A new extension was added, making the drive a "V" shape and joining the Northern road further north, roughly in line but to the east of the main homestead and farm management complex. The subdivision of Harrington Park in the 1990s for urban development has visually encroached upon Orielton estate, with suburb abutting The Northern Road alongside it and Kirkham Lane large-lot residences approaching its south-western flanks north of Narellan Creek. Cattle grazing fields and shelter sheds lining Orielton's northern edge of Narellan Creek are apparent in a 1990 aerial photograph but absent in a 2005 one. The original grant and its management for grazing can still be understood in the broader landscape of the Narellan Valley.
