Cameron Corner Survey Marker is a heritage-listed survey marker in the locality of Cameron Corner, Shire of Bulloo, Queensland, Australia. The survey marker is at the border corner of South-West Queensland with New South Wales and South Australia; it was established in 1880. It was added to the Queensland Heritage Register on 9 November 2012.
Cameron Corner Survey Marker was established in September 1880 during the first official survey of the western section of the border between Queensland and New South Wales (NSW) undertaken in 1879-1881. It defines the westernmost extension of the Queensland-New South Wales border. Its marking was a surveying feat of its time.
After debate about a suitable southern boundary for the proposed new colony to the north of New South Wales (NSW), letters patent were issued by Queen Victoria in June 1859 which separated the new Colony of Queensland from NSW. The letters patent described the border between the two colonies as having three components:
The eastern and western sections of the border required surveying but the central river section did not.
The eastern section was surveyed between 1863 and 1866. In 1863 surveyors Francis Edward Roberts from Queensland and Isaiah Rowland from New South Wales were chosen to survey the boundary line from Point Danger west to the Dumaresq River. Starting in June, two separate surveys were carried out, and although in many instances both surveyors used the same tree to mark the border, Rowland and Roberts defined the border in different positions. At the direction of the Queensland Surveyor-General, Roberts deviated from the definable position of the watershed in order to increase the accuracy of the survey. Subsequently, the New South Wales and Queensland governments essentially adopted the survey of Roberts.
Marking the river section formed by the Dumaresq, Macintyre and Barwon Rivers to 29 degrees South took place in 1865. Queensland and New South Wales arranged for the fixing of the 29th parallel of latitude, at the intersections of the Barwon, Mooni, Bokhara, Narran, Biri and Culgoa Rivers, to enable the colonial governments to adjust the rents of leases of several pastoral runs in the vicinity, some of which were partly in both colonies. In addition, about 450,000 acres of land on the Queensland border could not be leased until its position was determined.Augustus Charles Gregory, Queensland Surveyor-General and NSW District Surveyor of the Northern Rivers, William Albert Baylesford Greaves, conducted this initial survey of latitude 29S. The marking of the border was done with steel (iron) pins one inch in diameter and two feet long, driven a few inches below the surface, radial reference bearings being taken to adjacent trees.This process was repeated at each of the above named rivers, and the work was completed in five or six weeks.
