138th meridian east
The meridian 138° east of Greenwich is a line of longitude that extends from the North Pole across the Arctic Ocean, Asia, the Pacific Ocean, Australasia, the Indian Ocean, the Southern Ocean, and Antarctica to the South Pole.
In Australia, the border between the Northern Territory and Queensland approximates the meridian. The border runs north from Poeppel Corner at a bearing of 359° 59' 30", reaching the Gulf of Gulf of Carpentaria several hundred metres west of the meridian.
