Extreme points of the Commonwealth of Nations
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.
