Antipodes
The antipodes of the British Isles lie in the South Pacific, between New Zealand's Campbell Islands (off southern Ireland) and Antipodes Islands (across the Channel in Normandy). However, several British Overseas Territories are antipodal to land.
The antipodes of the Falkland Islands overlie the border of Chinese northern Inner Mongolia and Russian Siberia (Trans-Baikal Territory). Neighboring uninhabited South Georgia Island equates to the northern tip of Sakhalin. The southern South Sandwich Islands overlap with Russia near Magadan.
Gibraltar just touches the coast of New Zealand between Auckland and Whangarei. The Pitcairns are in Saudi Arabia, near the coast with Qatar and Bahrain, while neighboring Ducie's are in the UAE between Dubai and Abu Dhabi. Bermuda isn't antipodal to land, but is close, within 30 km of the Australian coast near Perth.
