The 26th parallel south latitude is a circle of latitude that is 26 degrees south of the Earth's equatorial plane. It crosses the Atlantic Ocean, Africa, the Indian Ocean, Australasia, the Pacific Ocean and South America.
Around the world
Starting at the Prime Meridian and heading eastwards, the parallel 26° south passes through:
Australian borders on 26th parallel south
In Australia, the northernmost border of South Australia, and the southernmost border of the Northern Territory are defined by 26° south. As well as these, 26° south also defines an approximately 127 metre section of the Western Australia/Northern Territory border.[1]
Longest straight border in the world?
The Western Australian border is defined by the 129th meridian east and if taken literally, it is the longest straight border in the world, however the border marked on the ground, at the point at which 129° east meets 26° south, the border turns 90° to the east to meet at what has been named as Surveyor Generals Corner.[1]
It is at Surveyor Generals Corner on 26° south that the border of Western Australia meets the western Northern Territory border and the western South Australian border.[1]
A Short straight border
Due to early inaccuracies in the 1920s for fixing positions under constraints of available technology, 26° south also defines an approximately 127 metre east-west section of the Western Australia/Northern Territory border.[1]
