Cuppacumbalong is an historic homestead located near the southern outskirts of Canberra in the Australian Capital Territory. It is also the name of a former 4,000-acre (16 km2) sheep and cattle grazing property that surrounded the homestead near the junction of the Murrumbidgee and Gudgenby Rivers. The word Cuppacumbalong is Aboriginal in origin and means 'meeting of the waters'. One of the property's early owners Leopold Fabius Dietegen Fane De Salis made a noteworthy contribution to political life during colonial times and furthermore, Cuppacumbalong has strong connections to the life of William Farrer, the father of the Australian wheat industry.
Englishmen James Wright and a friend John Hamilton Mortimer Lanyon migrated to Australia during the early 1830s. In 1833 they were amongst the first squatters to established sheep runs in the Queanbeyan region, building the Lanyon Homestead. In 1835 they acquired several adjoining blocks on the Murrumbidgee River. Wright established Cuppacumbalong located on the southern side of the Murrumbidgee River in 1839. At the time this region was situated outside the Nineteen Counties of New South Wales and despite the uncertainty of land tenure, many squatters ran large numbers of sheep and cattle beyond the boundaries. By one current-day account 'Cuppacumbalong' stretched 30 miles (48 km) southward to presentday Bredbo. In 1848 financial difficulties forced Wright to sell Lanyon to Andrew Cunningham and shift his operations to Cuppacumbalong. Wright sold 'Cuppacumbalong' to the de Salis family in 1855.
Leopold Fabius Dietegen Fane de Salis (1816–1898), pastoralist and politician, was born on 26 April 1816 in Florence, Italy, the fourth son of Jerome Fane, fourth Count de Salis, the third son by his third wife Henrietta, a daughter of William Foster (bishop). Sir William Foster Stawell, later the Chief Justice of the Supreme Court of the colony of Victoria was his first cousin.
