Today there are no registered Aboriginal sites within the Gwambygine farm property, but the Avon River and the Pool do have mythological significance.

At the age of 42, accompanied by his sister Eliza and four sons John, Henry, Frederick and Charles, Wittenoom left England on 14 August 1829 on the Wanstead, a barque bound for the Swan River and Tasmania.

This is believed to mean 'a good place to stay' and so it has proved for the three main families who have lived here, the Wittenooms, Hicks and Cliftons.

In 1836 the teenage sons of Reverend John Burdett Wittenoom, together with Thomas Carter an early settler from Norfolk, started building the first sections of the house.

Initially, Carter worked on the property undertaking improvement duties for the Reverend Wittenoom, and farmed wheat and sheep.

Reverend Wittenoom died on 23 January 1855 at the age of 66 years, a distinguished and much renowned clergyman and prominent member of the Swan River Colonial community.

On Charles' untimely death in 1866, aged only 42, he left the property to his two sons Frank and Edward Wittenoom who continued with the Hicks lease.

In 1899, Joseph Hicks junior's other daughter Florence married Claude Robert Henry Clifton, a northwest pastoralist.

The original, central, structure of the house is made of rammed earth, a mix of clay, sand and straw, with a mud and lime render.

Pamela's husband Nick was then treasurer of the Federation of Australian Historical Societies and heard through this body that part of the Rudd Governments job stimulus package was to be quarantined for Heritage projects if they were 'shovel ready'.

[4] Ron joined Pamela and Nick and Tony Clack of the River Conservation Society (the Gwambygine Group) in placing an application to the Federal Government for funds to undertake the restoration,[5] and another request was sent to the Western Australian Heritage Commission.

They also repaired the timberwork and carefully and painstakingly in-filled damage to the mud walls and brickwork, which they then whitewashed with a special formula.

Gwambygine, with its high-pitched roof and shady verandas, conforms to the early pattern for rural Western Australian houses.

It also shows the extensions carried out to provide additional accommodation for increased family needs and improved amenity over the life of the building.

As a building dating from 1836, the fabric reflects the means by which early buildings were constructed; mud walling from clay dug on the property plus sand and fermented straw, rough hewn timber roof framing cut on the property and supporting the original grasstree roof covering, later to be replaced with timber shingles, and later in the 19th century, when corrugated iron became available, with corrugated iron sheeting over the shingles for weatherproofing.

5561 Southern Highway, comprising 36.77 hectares (90.86 acres) incorporating Gwambygine Homestead, in the ownership of Margaret (Maggie) Venerys, the daughter of Brian Merton Clifton.

Former elements of Gwambygine Farm that have not survived the vicissitudes of time and decay due to flooding and earthquake, are the large shed north of the Homestead, the timber-framed building and the air raid shelter between the Homestead and the Pool, the duck yards, parts of the orchard which included olives, pears, figs and pomegranates, the vegetable garden and the jetty into the Pool.

The Clifton family's Cave Hill House opposite Gwambygine Homestead to the west and Millbrook to the southwest, survive as early 19th century elements in the rural and social life of the locality.
