129th meridian east
The meridian 129° east of Greenwich is a line of longitude that extends from the North Pole across the Arctic Ocean, Asia, Australia, the Indian Ocean, the Southern Ocean, and Antarctica to the South Pole.
In Australia, the meridian defines the eastern border of Western Australia, and the western borders of the Northern Territory and South Australia. The border of Western Australia meets the Northern Territory border and South Australian border at the 26th parallel south, at what is known as Surveyor Generals Corner.
