Extreme Points of The Commonwealth of Nations - Longitude

Longitude

Using lines of longitude (rather than the International Date Line), the eastern-most and western-most points in the Commonwealth are the same, as the 180th meridian goes through three Fijian islands, as well as New Zealand's Antarctic Ross Dependency. The three Fijian islands are Vanua Levu (far eastern peninsula, near Nambouono), Taveuni (centre of the island), and Rabi (western tip). However, Fiji is currently suspended from the Commonwealth. Thus, including only active members (and excluding the Ross Dependency), Tuvalu contains the most western and eastern points.

Using the International Date Line yields different results for the most eastern-most and western-most points, as it is drawn such that all Commonwealth members lie either to the west or east of it – and not across it – to simplify administration. In this case, the westernmost point is on Banaba Island, in Kiribati, at 169°32'13"E. The easternmost point is on Niue, a state free association with New Zealand, at 169°52'11"W. Including only territories that are themselves directly members of the Commonwealth, the westernmost point would be on Vatoa, Fiji, at 178°15'W. Excluding suspended Fiji as well, it is Nukulaelae, Tuvalu, at 179°51'E.
