In Australia the meridian nominally defines the eastern border of Western Australia with the Northern Territory and South Australia.

The 129th meridian east forms a great circle with the 51st meridian west.

In Australia, the meridian nominally defines the eastern border of Western Australia, and the western borders of the Northern Territory and South Australia.^[2] 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.^[3]
