The old saying goes, if you dig down deep enough you'll reach China. But this is not true, rather if you dig down from the United States you'll end up in the Indian Ocean, unless you're in Hawaii. Directly straight down underneath Hawaii is the southern tip of Africa. Thus all of Hawaii can fly this flag. Likewise the small parts of Botswana and Namibia antipodal to Hawaii can fly this flag. However the flag should be flipped when flown in the Southern Hemisphere, so that the fly is white and the hoist is green. Also note the tilt of the blue stripe matches the Earth's tilt relative to its orbit around the sun at about 23 degrees. Coincidentally about 23 percent of the land on Earth is antipodal. Besides Hawaii, a small slice of Alaska and Montana can fly this flag. Alaska is underneath Antarctica while a northern nibble of Montana is underneath the Kerguelen.
Wholly Antipodal countries that can fly this flag anywhere across their lands include: the Philippines, Brunei, Sarawak, and Taiwan. Nations that are mostly Antiopdal include: Chile, Argentina, Cambodia, Greenland and Indonesia. And nations with a good part of the area Antipodal include: New Zealand's North Island, Ecuador, South Vietnam, and Peru.
