Experts from both the Surveyor-General Victoria (SGV) and NSW DCS Spatial Services recently travelled to Mildura to make inspections and determine the position of a portion of the Victoria-NSW state border.

Specifically, the inspection team determined the precise line of the border between the nine-span, 331-metre-long George Chaffey Bridge (part of the Sturt Highway) and the downstream weir.

The weeklong inspection was conducted with low water levels, enabling maintenance and examination of the weir’s submerged banks.

The border determination was a complex process that involved legal precedents and guidelines, with historical information such as water level recordings, survey documents, topographical surveys and old photographs being pressed into service.

Once agreement was reached on the location of the border, position recordings were made by SGV surveyors — those positions will now be formally surveyed and marked ahead of a forthcoming plan of survey of the State border.
