The border which runs along the eastern edge of Western Australia is not actually one continuous straight line. [...] The [1922] agreement set out the border as being a line determined by the 129th meridian east longitude. However, the agreement required that the boundary be defined by lines running north and south [...] and in June 1968 two monuments approximately 127 metres apart were erected at the junction of the boundaries. However, the border of Western Australia actually meets the Northern Territory border and South Australian border at the 26th parallel south, at what is known as Surveyor Generals Corner.AN HISTORICAL PERSPECTIVE - Longitude 129 degrees east, and why it is not the longest, straight line in the world Eyepiece - Official Organ of The Institution of Surveyors, Australia, W.A.
