However, the actual evidence shows otherwise.

“The land border of the state of Western Australia (WA) bisects mainland Australia, nominally along 129th meridian east longitude (129° East). That land border divides WA from the Northern Territory (NT) and South Australia (SA). However, for various reasons, the actual border (as surveyed and marked or otherwise indicated on the ground) deviates from 129° East, and is not a single straight line.[1]
The Western Australian town closest to the border is Kununurra, which is about 25 kilometres (16 mi) west of the border with the NT. The settlement outside WA that is closest to the border is Border Village, SA, which adjoins the border; the centre of Border Village is about 250 metres (820 ft) from the border, on the Eyre Highway.
Border delineation
In some cases, the physical signage and structures that mark the actual border deviate from the 129th meridian. The Northern Territory border with Western Australia and the South Australian border with Western Australia are displaced east–west by approximately 127 metres (417 ft), as a result of errors caused by the technical limits of surveying technology in the 1920s,[1] when the current border was surveyed.
Consequently, since the 1920s, the border has included an approximate 127-metre (417 ft) east–west “dog-leg”, which runs along the 26th parallel south latitude (26° south),[1] immediately west of Surveyor Generals Corner – the point at which WA officially meets both the NT and SA. In June 1968, monuments were erected to mark both ends of this 127-metre (417 ft) east–west line.[1]
