An antipode is something which is opposite or diametrically opposed to something else.
antipodal
The opposite end of the Earth from Spokane, also known as its antipode, is a point in the southern Indian Ocean. The nearest land mass is the French Southern and Antarctic Lands, which is the only antipodal land mass to the entire continental US. It is antipodal to a small area of northern Montana, near the Canadian border.

The antipodal (opposite side of the globe) of the continental US is in the Indian Ocean and therefore is the farthest point. So much for digging to China.
final, antipodal, aftermost, hindmost, farthest, furthest.
Oceans and Continents are diametrically opposite to each other

There's no country, only a big ocean - Pacific Ocean. Geographic coordinates of Estonia: 26 E, 59 N Coordinates of the antipodal point: 154 W, 59 S
Antipodes are the opposite ends of the Earth, and hence of anything. Antipode and antipodal derive from it.
